* Added BShape::ArcTo() and BShapeIterator::IterateArcTo(), using a previously
unused virtual slot. (Added the symbols for binary compatibility for GCC2
and GCC4.)
* Added operator=(), operator==() and operator!=() to BShape.
* Added BShape::BezierTo() version taking three points, which is sometimes
more convenient.
* Added the four new shape data ops OP_LARGE_ARC_TO_CW, OP_LARGE_ARC_TO_CCW,
OP_SMALL_ARC_TO_CW and OP_SMALL_ARC_TO_CCW. For a single arc, provided the
radius is large enough, there are four possibilities to draw the arc, these
are controlled by the two boolean flags to ArcTo() and mapped to the new
commands accordingly.
* Some style cleanup in Shape.cpp (sorry for mixing it up, but it gets
worse below...)
* Added ShapeTest to src/tests/servers/app.
* Changed the way BShapes are transformed from view to screen space in the
app_server. For arcs, it would be nontrivial to apply a proper transformation,
it's much easier to let AGG take care of it. This affects ServerPicture as
well.
* Wrapped iterating the BShape into try/catch blocks in ShapeIterator. But
I really don't understand the purpose of the class in the first place.
Maybe it can now be dropped, since coordinates don't have to be transformed
in place anymore.
* Refactored copy&paste shape iteration code in Painter. The transformation
to screen space happens there.
* Since RemoteDrawingEngine needed to be adopted anyway, I also updated
it for the new DrawString() with offsets version. But the client still needs
to be adapted.
* Style cleanup in Painter.h

support file creation.
* Extended open() and open_from() to support O_CREAT to create files.
open_from() has got an optional "permissions" parameter for that purpose.
* Fixed errno. It would crash when being used. Also changed the POSIX functions
to return their error code via errno as expected.
* Added writev().
* FAT file system:
- Added support for reading long file names.
- Added support for creating files (8.3 name only) and writing to them.
- Enabled scanning partitions with it.
* Boot loader menu:
- Enabled the "Reboot" menu item unconditionally.
- Added "Save syslog from previous session" menu item to the debug menu.
Currently saving the syslog to FAT32 volumes is supported.

not be handled. Added thread::sig_temp_enabled, an additional mask of not
blocked signals, which is set by sigsuspend() and evaluated and reset by
handle_signals(). Fixes#5567.

* The kernel syslog ring buffer is no longer emptied by the syslog sender
thread. Instead we only drop the oldest data from the buffer when we're
writing to it and there's not enough free space in it.
Advantages: We drop old data rather than the most recent data when the buffer
is full. The "syslog" KDL command has more data available now. So the odds
are that kernel syslog messages not written to disk yet are at least still
in the kernel buffer.
* Changed dprintf_no_syslog() semantics: Now it writes to the syslog, but
doesn't notify the syslog sender thread.
boot loader:
* Added the ring_buffer implementation and a dummy user_memcpy().
* bios_x86: Moved the syslog stuff from serial.{cpp,h} to debug.{cpp.h}.
* Moved the debug options from the "Select safe mode options" menu to a new
"Select debug options" menu.
* Added option "Enable debug syslog" to the new menu (ATM available on x86
only). It allocates a 1 MB in-memory buffer for the syslog for this session
in such a way that it can be accessed by the boot loader after a reset.
* Added item "Display syslog from previous session" to the new menu, doing
what its name suggests.

* Reused the existing mechanism to to have hardcoded tokens for the system
cursors, i.e. removed cursor_which enumeration from ServerProtocol.h and
used BCursorID where cursor_which was previously used.
* Reworked CursorManager.h and CursorSet.h accordingly and removed some methods
that where intended to replace system cursors with client cursors, since
those would break the reference counting and forget to maintain the cursor
list.
* Replaced the cursors in CursorData.h/cpp with the new ones I just designed.
* Removed HaikuSystemCursor.h and HaikuLogo.h from the source, as those are/were
no longer used.
I hope I will not get too much beating for this one... :-) I know the new
default cursor is slightly larger, but I believe the old one was just too small.
Also I noticed that the cursor may be slightly too dark, at least the old one
seems noticeably brighter when compared side by side (the new one has a slight
gradient). That is something I may correct at least. Otherwise I hope nothing
is broken, I've tested in QEMU and so far everything works as intended.

* Extended BTime, BDate and BDateTime with archiving functionality.
* Adjusted code which uses these classes, since including DateTime.h
already imports the classes from the BPrivate namespace.
* Moved DateTime.h into Support Kit. It is still in the BPrivate namespace,
as I am uncertain what to do with time_type and diff_type. I'd favor
moving the constants into the classes itself. Possibly removing the B_
prefix from them. Feedback welcome.

* Made the page table allocation more flexible. Got rid of sMaxVirtualAddress
and added new virtual_end address to the architecture specific kernel args.
* Increased the virtual space we reserve for the kernel to 16 MB. That
should suffice for quite a while. The previous 2 MB were too tight when
building the kernel with debug info.
* mmu_init(): The way we were translating the BIOS' extended memory map to
our physical ranges arrays was broken. Small gaps between usable memory
ranges would be ignored and instead marked allocated. This worked fine for
the boot loader and during the early kernel initialization, but after the
VM has been fully set up it frees all physical ranges that have not been
claimed otherwise. So those ranges could be entered into the free pages
list and would be used later. This could possibly cause all kinds of weird
problems, probably including ACPI issues. Now we add only the actually
usable ranges to our list.
Kernel:
* vm_page_init(): The pages of the ranges between the usable physical memory
ranges are now marked PAGE_STATE_UNUSED, the allocated ranges
PAGE_STATE_WIRED.
* unmap_and_free_physical_pages(): Don't free pages marked as unused.

happen on syscalls or "int" instructions. The debug exception handler sets
the thread debug flags B_THREAD_DEBUG_STOP and
B_THREAD_DEBUG_NOTIFY_SINGLE_STEP (new) and lets the thread continue. Before
leaving the kernel the thread is stopped and a single-step notification is
sent. Fixes#3487.

they were never freed unless the cache was destroyed (I just wondered why
my system would bury >1G in the magazines).
* Made the magazine capacity variable per cache, ie. for larger objects, it's
not a good idea to have 64*CPU buffers lying around in the worst case.
* Furthermore, the create_object_cache_etc()/object_depot_init() now have
arguments for the magazine capacity as well as the maximum number of full
unused magazines.
* By default, you might want to initialize both to zero, as then some hopefully
usable defaults are computed. Otherwise (the only current example is the
vm_page_mapping cache) you can just put in the values you'd want there.
The page mapping cache uses larger values, as its objects are usually
allocated and deleted in larger chunks.
* Beware, though, I couldn't test these changes yet as Qemu didn't like to run
today. I'll test these changes on another machine now.

needs to be or'ed to the address specification), "uncached" is assumed.
* Set the memory type for the "BIOS" and "DMA" areas to write-back. Not sure, if
that's correct, but that's what was effectively used on my machines before.
* Changed x86_set_mtrrs() and the CPU module hook to also set the default memory
type.
* Rewrote the MTRR computation once more:
- Now we know all used memory ranges, so we are free to extend used ranges
into unused ones in order to simplify them for MTRR setup.
- Leverage the subtractive properties of uncached and write-through ranges to
simplify ranges of any other respectively write-back type.
- Set the default memory type to write-back, so we don't need MTRRs for the
RAM ranges.
- If a new range intersects with an existing one, we no longer just fail.
Instead we use the strictest requirements implied by the ranges. This fixes
#5383.
Overall the new algorithm should be sufficient with far less MTRRs than before
(on my desktop machine 4 are used at maximum, while 8 didn't quite suffice
before). A drawback of the current implementation is that it doesn't deal with
the case of running out of MTRRs at all, which might result in some ranges
having weaker caching/memory ordering properties than requested.

* Fix the TimeFormat API, there was a double free. Make it work as expected : you send it a number of seconds and it will format it properly in days, hours, minutes, seconds with proper plural.
* Cleanup other parts of the Format API from useless things. They may get reintroduced later if we feel the need to do so.
* AboutSystem now use TimeFormat to display the uptime in properly localized way.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35506 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added vm_clear_page_mapping_accessed_flags() and
vm_remove_all_page_mappings_if_unaccessed(), which combine the functionality
of vm_test_map_activation(), vm_clear_map_flags(), and
vm_remove_all_page_mappings(), thus saving lots of calls to translation map
methods. The backend is the new method
VMTranslationMap::ClearAccessedAndModified().
* Started to make use of the cached page queue and changed the meaning of the
other non-free queues slightly:
- Active queue: Contains mapped pages that have been used recently.
- Inactive queue: Contains mapped pages that have not been used recently. Also
contains unmapped temporary pages.
- Modified queue: Contains unmapped modified pages.
- Cached queue: Contains unmapped unmodified pages (LRU sorted).
Unless we're actually low on memory and actively do paging, modified and
cached queues only contain non-temporary pages. Cached pages are considered
quasi free. They still belong to a cache, but since they are unmodified and
unmapped, they can be freed immediately. And this is what
vm_page_[try_]reserve_pages() do now when there are no more actually free
pages at hand. Essentially this means that pages storing cached file data,
unless mmap()ped, no longer are considered used and don't contribute to page
pressure. Paging will not happen as long there are enough free + cached pages
available.
* Reimplemented the page daemon. It no longer scans all pages, but instead works
the page queues. As long as the free pages situation is harmless, it only
iterates through the active queue and deactivates pages that have not been
used recently. When paging occurs it additionally scans the inactive queue and
frees pages that have not been used recently.
* Changed the page reservation/allocation interface:
vm_page_[try_]reserve_pages(), vm_page_unreserve_pages(), and
vm_page_allocate_page() now take a vm_page_reservation structure pointer.
The reservation functions initialize the structure -- currently consisting
only of a count member for the number of still reserved pages.
vm_page_allocate_page() decrements the count and vm_page_unreserve_pages()
unreserves the remaining pages (if any). Advantages are that reservation/
unreservation mismatches cannot occur anymore, that vm_page_allocate_page()
can verify that the caller has indeed a reserved page left, and that there's
no unnecessary pressure on the free page pool anymore. The only disadvantage
is that the vm_page_reservation object needs to be passed around a bit.
* Reworked the page reservation implementation:
- Got rid of sSystemReservedPages and sPageDeficit. Instead
sUnreservedFreePages now actually contains the number of free pages that
have not yet been reserved (it cannot become negative anymore) and the new
sUnsatisfiedPageReservations contains the number of pages that are still
needed for reservation.
- Threads waiting for reservations do now add themselves to a waiter queue,
which is ordered by descending priority (VM priority and thread priority).
High priority waiters are served first when pages become available.
Fixes#5328.
* cache_prefetch_vnode(): Would reserve one less page than allocated later, if
the size wasn't page aligned.

* Remove no longer necessary support functions.
* The new version uses a single BString as input/output parameter and only
modifies that one by removing non-fitting chars and inserting the ellipsis
where appropriate, so avoids copying around bytes/chars/strings in a few
places. It uses the new Chars functions of BString so also no need for manual
multibyte handling.
* Adjusted the BFont and ServerFont usage of truncate_string() which are both
simplified by using the single BString. It avoids a lot of temprary
allocations and string copying. The char * version of BFont
GetTruncatedStrings() now uses the BString version and not the other way
around anymore which requires us to allocate temporary BString objects, it's
not worse than before though.
* This fixes a bunch of problems with the previous functions like always
prepending the ellipsis for B_TRUNCATE_BEGINNING, crashing on short enough
widths, violating the width in the B_TRUNCATE_END case when the width was
short enough, non-optimal truncation in a few cases and sometimes truncation
where none would've been needed. Also fixes#4128 which was a symptom of the
broken B_TRUNCATE_BEGINNING.

general "flags" parameter. It encodes the target state of the page -- so
that the page isn't unnecessarily put in the wrong page queue first -- a
flag whether the page should be cleared, and one to indicate whether the
page should be marked busy.
* Added page state PAGE_STATE_CACHED. Not used yet.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35333 a95241bf-73f2-0310-859d-f6bbb57e9c96
flag. The obvious advantage is that one can still see what state a page is in
and even move it between states while being marked busy.
* Removed the vm_page::is_dummy flag. Instead we mark marker pages busy, which
in all cases has the same effect. Introduced a vm_page_is_dummy() that can
still check whether a given page is a dummy page.
* vm_page_unreserve_pages(): Before adding to the system reserve make sure
sUnreservedFreePages is non-negative. Otherwise we'd make nonexisting pages
available for allocation. steal_pages() still has the same problem and it
can't be solved that easily.
* map_page(): No longer changes the page state/mark the page unbusy. That's the
caller's responsibility.

argument. They replace the previous special-purpose allocation functions
(malloc_nogrow(), vip_io_request_malloc()).
* Moved the I/O VIP heap to heap.cpp accordingly.
* Added quite a bit of passing around of allocation flags in the VM,
particularly in the VM*AddressSpace classes.
* Fixed IOBuffer::GetNextVirtualVec(): It was ignoring the VIP flag and always
allocated on the normal heap.

memory and page reservation functions have a new "priority" parameter that
indicates how deep the function may tap into that reserve. The currently
existing priority levels are "user", "system", and "VIP". The idea is that
user programs should never be able to cause a state that gets the kernel into
trouble due to heavy battling for memory. The "VIP" level (not really used
yet) is intended for allocations that are required to free memory eventually
(in the page writer). More levels are thinkable in the future, like "user real
time" or "user system server".
* Added "priority" parameters to several VMCache methods.
* Replaced the map_backing_store() "unmapAddressRange" parameter by a "flags"
parameter.
* Added area creation flag CREATE_AREA_PRIORITY_VIP and slab allocator flag
CACHE_PRIORITY_VIP indicating the importance of the request.
* Changed most code to pass the right priorities/flags.
These changes already significantly improve the behavior in low memory
situations. I've tested a bit with 64 MB (virtual) RAM and, while not
particularly fast and responsive, the system remains at least usable under high
memory pressure.
As a side effect the slab allocator can now be used as general memory allocator.
Not done by default yet, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35295 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added support to do larger raw allocations (up to one large chunk (128 pages))
in the slab areas. For an even larger allocation an area is created (haven't
seen that happen yet, though).
* Added kernel tracing (SLAB_MEMORY_MANAGER_TRACING).
* _FreeArea(): Copy and paste bug: The meta chunks of the to be freed area
would be added to the free lists instead of being removed from them. This
would corrupt the lists and also lead to all kinds of misuse of meta chunks.
object caches:
* Implemented CACHE_ALIGN_ON_SIZE. It is no longer set for all small object
caches, but the block allocator sets it on all power of two size caches.
* object_cache_reserve_internal(): Detect recursion and don't wait in such a
case. The function could deadlock itself, since
HashedObjectCache::CreateSlab() does allocate memory, thus potentially
reentering.
* object_cache_low_memory():
- I missed some returns when reworking that one in r35254, so the function
might stop early and also leave the cache in maintenance mode, which would
cause it to be ignored by object cache resizer and low memory handler from
that point on.
- Since ReturnSlab() potentially unlocks, the conditions weren't quite correct
and too many slabs could be freed.
- Simplified things a bit.
* object_cache_alloc(): Since object_cache_reserve_internal() does potentially
unlock the cache, the situation might have changed and their might not be an
empty slab available, but a partial one. The function would crash.
* Renamed the object cache tracing variable to SLAB_OBJECT_CACHE_TRACING.
* Renamed debugger command "cache_info" to "slab_cache" to avoid confusion with
the VMCache commands.
* ObjectCache::usage was not maintained anymore since I introduced the
MemoryManager. object_cache_get_usage() would thus always return 0 and the
block cache would not be considered cached memory. This was only of
informational relevance, though.
slab allocator misc.:
* Disable the object depots of block allocator caches for object sizes > 2 KB.
Allocations of those sizes aren't so common that the object depots yield any
benefit.
* The slab allocator is now fully self-sufficient. It allocates its bootstrap
memory from the MemoryManager, and the hash tables for HashedObjectCaches use
the block allocator instead of the heap, now.
* Added option to use the slab allocator for malloc() and friends
(USE_SLAB_ALLOCATOR_FOR_MALLOC). Currently disabled. Works in principle and
has virtually no lock contention. Handling for low memory situations is yet
missing, though.
* Improved the output of some debugger commands.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35283 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added optional parameter "void** oldTable" to Resize(). If given the old
allocation for the table is returned instead of freeing it.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35278 a95241bf-73f2-0310-859d-f6bbb57e9c96
CACHE_DONT_LOCK_KERNEL_SPACE. If the former is given, the slab memory manager
does not wait when reserving memory or pages. The latter prevents area
operations. The new flags add a bit of flexibility. E.g. when allocating page
mapping objects for userland areas CACHE_DONT_WAIT_FOR_MEMORY is sufficient,
i.e. the allocation will succeed as long as pages are available.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35246 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented a more elaborated raw memory allocation backend (MemoryManager).
We allocate 8 MB areas whose pages we allocate and map when needed. An area is
divided into equally-sized chunks which form the basic units of allocation. We
have areas with three possible chunk sizes (small, medium, large), which is
basically what the ObjectCache implementations were using anyway.
* Added "uint32 flags" parameter to several of the slab allocator's object
cache and object depot functions. E.g. object_depot_store() potentially wants
to allocate memory for a magazine. But also in pure freeing functions it
might eventually become useful to have those flags, since they could end up
deleting an area, which might not be allowable in all situations. We should
introduce specific flags to indicate that.
* Reworked the block allocator. Since the MemoryManager allocates block-aligned
areas, maintains a hash table for lookup, and maps chunks to object caches,
we can quickly find out which object cache a to be freed allocation belongs
to and thus don't need the boundary tags anymore.
* Reworked the slab boot strap process. We allocate from the initial area only
when really necessary, i.e. when the object cache for the respective
allocation size has not been created yet. A single page is thus sufficient.
other:
* vm_allocate_early(): Added boolean "blockAlign" parameter. If true, the
semantics is the same as for B_ANY_KERNEL_BLOCK_ADDRESS.
* Use an object cache for page mappings. This significantly reduces the
contention on the heap bin locks.

one for each per CPU store):
* The depot is now protected by a R/W lock combined with a spinlock. It is
required to either hold read lock + spinlock or just the write lock.
* When accessing the per CPU stores we only need to acquire the read lock
and disable interrupts. When switching magazines with the depot we
additionally get the spinlock.
* When allocating a new magazine we do completely unlock.

* The threads beside the main thread are killed earlier now (in the new
team_shutdown_team()), before removing the team from the team hash and from
its process group. This fixes#5296.
* Use a condition variable instead of a semaphore to wait for the non-main
threads to die. We notify the condition right after a thread has left the
team. The semaphore was released by the undertaker.

VMCacheRef object which points to the cache. This allows to optimize
VMCache::MoveAllPages(), since it no longer needs to iterate over all pages
to adjust their cache pointer. It can simple swap the cache refs of the two
caches instead.
Reduces the total -j8 Haiku image build time only marginally. The kernel time
drops almost 10%, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35155 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added "bool consumerLocked" parameter to VMCache::Unlock() and
ReleaseRefAndUnlock(). Since Unlock() may cause the cache to be merged with
a consumer cache, the flag is needed to prevent a deadlock in case the
caller still holds a lock to the consumer. Hasn't been a problem yet, since
that situation never occurred.
* VMCacheChainLocker: Reversed unlocking order to bottom-up. The other
direction could cause a deadlock in case caches would be merged, since the
locking order would be reversed. The way VMCacheChainLocker was used this
didn't happen, though.
* fault_get_page(): While copying a page from a lower cache to the top cache,
we do now unlock all caches but the top one, so we don't unnecessarily
kill concurrency.

* Reorganized the code for [un]mapping pages:
- Added new VMTranslationMap::Unmap{Area,Page[s]}() which essentially do what
vm_unmap_page[s]() did before, just in the architecture specific code, which
allows for specific optimizations. UnmapArea() is for the special case that
the complete area is unmapped. Particularly in case the address space is
deleted, some work can be saved. Several TODOs could be slain.
- Since they are only used within vm.cpp vm_map_page() and vm_unmap_page[s]()
are now static and have lost their prefix (and the "preserveModified"
parameter).
* Added VMTranslationMap::Protect{Page,Area}(). They are just inline wrappers
for Protect().
* X86VMTranslationMap::Protect(): Make sure not to accidentally clear the
accessed/dirty flags.
* X86VMTranslationMap::Unmap()/Protect(): Make page table skipping actually
work. It was only skipping to the next page.
* Adjusted the PPC code to at least compile.
No measurable effect for the -j8 Haiku image build time, though the kernel time
drops minimally.

currently similar to HashMap, which is also based on that version. The kernel
has OpenHashTable by Hugo Santos, which is a bit nicer, but I didn't want to
change too much code, although HashMap and HashSet exist for this as well.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35077 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Pulled the physical page mapping functions out of vm_translation_map into
a new interface VMPhysicalPageMapper.
* Renamed vm_translation_map to VMTranslationMap and made it a proper C++
class. The functions in the operations vector have become methods.
* Added class GenericVMPhysicalPageMapper implementing VMPhysicalPageMapper
as far as possible (without actually writing new code).
* Adjusted the x86 and the PPC specifics accordingly (untested for the
latter). For the other architectures the build is, I'm afraid, seriously
broken.
The next steps will modify and extend the VMTranslationMap interface, so that
it will be possible to fix the bugs in vm_unmap_page[s]() and employ
architecture specific optimizations.

* ioapic_init(): map_physical_memory() was called for already mapped
addresses. This worked fine, but only because the x86 page mapping code
didn't mind.

Changed strings to sentence case in various places. This is the
case-misc.diff part of ticket #5169.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35043 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added myself to copyrights, since I added some stuff to MediaExtractor.

* Use atomic_{and,or}() instead of atomic_set(), as there are no built-ins
for the latter.

This makes appending the pages to the active queue more efficient and we
don't need the vm_page::is_cleared bit anymore.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35011 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added Debug{First,Next}() methods to allow easy iteration through the
address spaces in kernel debugger commands.

device path + child partition name. When a "raw" device is unpublished the node
removal notification triggers the partition and child partitions to be
unpublished/removed. Since in that case the "raw" node is already unpublished
trying to resolve it in devfs_unpublish_partition() again to unpublish the child
partitions would fail, leaving the child partition nodes behind. When a new raw
device would then become available publishing its partitions would fail because
of these left behind nodes, causing bug #4587. Seeing that this code is more
compact and straight forward anyway I don't quite see why it was changed in the
first place.

table. It is now inline and uses double-checked locking. This reduces the
contention on the lock to insignificant. Total -j8 Haiku image build speedup
is marginal, but the total kernel time drops 12%.

access to a vm_page. It is basically an atomically accessed thread ID field
in the vm_page structure, which is explicitly set by macros marking the
critical sections. As a first positive effect I had to review quite a bit of
code and found several issues.
* Added several TODOs and comments. Some harmless ones, but also a few
troublesome ones in vm.cpp regarding page unmapping.
* file_cache: PrecacheIO::Prepare()/read_into_cache: Removed superfluous
vm_page_allocate_page() return value checks. It cannot fail anymore.
* Removed the heavily contended "pages" lock. We use different policies now:
- sModifiedTemporaryPages is accessed atomically.
- sPageDeficitLock and sFreePageCondition are protected by a new mutex.
- The page queues have individual locks (mutexes).
- Renamed set_page_state_nolock() to set_page_state(). Unless the caller says
otherwise, it does now lock the affected pages queues itself. Also changed
the return value to void -- we panic() anyway.
* set_page_state(): Add free/clear pages to the beginning of their respective
queues as this is more cache-friendly.
* Pages with the states PAGE_STATE_WIRED or PAGE_STATE_UNUSED are no longer
in any queue. They were in the "active" queue, but there's no good reason
to have them there. In case we decide to let the page daemon work the queues
(like FreeBSD) they would just be in the way.
* Pulled the common part of vm_page_allocate_page_run[_no_base]() into a helper
function. Also fixed a bug I introduced previously: The functions must not
vm_page_unreserve_pages() on success, since they remove the pages from the
free/clear queue without decrementing sUnreservedFreePages.
* vm_page_set_state(): Changed return type to void. The function cannot really
fail and no-one was checking it anyway.
* vm_page_free(), vm_page_set_state(): Added assertion: The page must not be
free/clear before. This is implied by the policy that no-one is allowed to
access free/clear pages without holding the respective queue's lock, which is
not the case at this point. This found the bug fixed in r34912.
* vm_page_requeue(): Added general assertions. panic() when requeuing of
free/clear pages is requested. Same reason as above.
* vm_clone_area(), B_FULL_LOCK case: Don't map busy pages. The implementation is
still not correct, though.
My usual -j8 Haiku build test runs another 10% faster, now. The total kernel
time drops about 18%. As hoped the new locks have only a fraction of the old
"pages" lock contention. Other locks lead the "most wanted list" now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34933 a95241bf-73f2-0310-859d-f6bbb57e9c96
the internal dependencies into account. This should fix bugs #5166, #5120,
and #5150.
* Also, the time source object manager, as well as the dormant node manager
are now recreated on media roster restart (when the media server is
restarted).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34906 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Renamed page_queue to VMPageQueue and made it a proper C++ class. Use
DoublyLinkedList instead of own list code.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34874 a95241bf-73f2-0310-859d-f6bbb57e9c96
have one anymore anyway.
* Removed unnecessary setting the list links to NULL after removing a node.
* Replaced "element == NULL" check in Insert() by an assert. This just hid
potential errors.
* Added Insert{Before,After}() methods and declared the Insert() version
with the InsertBefore() semantics obsolete.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34873 a95241bf-73f2-0310-859d-f6bbb57e9c96
sure that the kernel's frame buffer console points to the right data.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34835 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Changed the rw_lock_{read,write}_unlock() return values to void. They
returned a value != B_OK only in case of user error and no-one checked them
anyway.
* Optimized rw_lock_read_[un]lock(). They are inline now and as long as
there's no contending write locker, they will only perform an atomic_add().
* Changed the semantics of nested locking after acquiring a write lock: Read
and write locks are counted separately, so read locks no longer implicitly
become write locks. This does e.g. make degrading a write lock to a read
lock by way of read_lock + write_unlock (as used in the VM) actually work.
These changes speed up the -j8 Haiku image build on my machine by a few
percent, but more interestingly they reduce the total kernel time by 25 %.
Apparently we get more contention on other locks, now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34830 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added VMCache::MovePage() and MoveAllPages() to move pages between caches.
* VMAnonymousCache:
- _MergeSwapPages(): Avoid doing anything, if neither cache has swapped out
pages.
- _MergeSwapPages() does now also remove source cache pages that are
shadowed by consumer swap pages. This allows us to call _MergeSwapPages()
before _MergePagesSmallerSource(), save the swap page shadowing check
there and get rid of the vm_page::merge_swap flag. This is an
optimization based on the assumption that usually none or only few pages
are swapped out, so we save a lot of checks.
- Implemented _MergePagesSmallerConsumer() as an alternative to
_MergePagesSmallerSource(). The former is used when the source cache has
more pages than the consumer cache. It iterates over the consumer cache's
pages, moves them to the source and finally moves all pages back to the
consumer. The final move is relatively cheap (though unfortunately we
still have to update all pages' vm_page::cache field), so that overall we
save iterations of the main loop with the more expensive checks.
The optimizations particularly improve the common fork()+exec*() situations.
fork() uses CoW, which is implemented by putting two new empty caches between
the to be copied area and its cache. exec*() destroys one copy of the area,
its cache and thus causes merging of the other new cache with the old cache.
Since this usually happens in a very short time, the old cache does still
contain many pages and the new cache only few. Previously the many pages were
all checked and moved individually. Now we do that for the few pages instead.
A very extreme example of this situation is the Haiku image build. jam has a
huge heap (> 200 MB) and it fork()s+exec*()s for every action to be executed.
Since during the cache merging the cache is locked, any write access to a
heap page causes jam to block until the cache merging is done. Formerly that
took so long that it killed a lot of parallelism in multi-job builds. That
could be observed particularly well when lots of small actions where executed
(like the Link, XRes, Mimeset, SetType, SetVersion combos when building
executables/libraries/add-ons). Those look dramatically better now.
The overall speed improvement for a -j8 image build on my machine is only
about 15%, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34784 a95241bf-73f2-0310-859d-f6bbb57e9c96
another. The code originates from vm_copy_on_write_area(). We now generate
the VM cache tracing entries, though.
* count_writable_areas() -> VMCache::CountWritableAreas()
* Added debugger command "cache_stack" which is enabled when VM cache tracing
is enabled. It prints the source caches of a given cache or area at the
time of a specified tracing entry.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34751 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Replaced the "userOnly" parameter by a "flags" parameter, that allows to
specify kernel and userland stack traces individually.
- x86, m68k: Don't always skip the first frame as that prevents the caller
from being able to record its own address.
* capture_tracing_stack_trace(): Replaced the "userOnly" parameter by
"kernelOnly", since one is probably always interested in the kernel stack
trace, but might not want the userland stack trace.
* Added stack trace support for VM cache kernel tracing.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34742 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added Lock()/Unlock() for explicit locking by a service user.
* Added NotifyLocked() and made Notify() inline.
* Added HasListeners() so one can check whether there is a listener at all
before preparing the event message.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34736 a95241bf-73f2-0310-859d-f6bbb57e9c96
- enqueue_in_run_queue() no longer returns whether rescheduling is supposed
to happen. Instead is sets cpu_ent::invoke_scheduler on the current CPU.
- reschedule() does now handle cpu_ent::invoke_scheduler_if_idle(). No need
to let all callers do that.
* thread_unblock[_locked]() no longer return whether rescheduling is supposed
to happen.
* Got rid of the B_INVOKE_SCHEDULER handling. The interrupt hooks really
can't know, when it makes sense to reschedule or not.
* Introduced scheduler_reschedule_if_necessary[_locked]() functions for
checking+invoking the scheduler.
* Some semaphore functions (e.g. delete_sem()) invoke the scheduler now, if
they wake up anything with greater priority.
I've also tried to add scheduler invocations in the condition variable and
mutex/rw_lock code, but that actually has a negative impact on performance,
probably because it causes too much ping-ponging between threads when
multiple locking primitives are involved.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34657 a95241bf-73f2-0310-859d-f6bbb57e9c96
* simple_smp scheduler: Rewrote the interesting part of
enqueue_in_run_queue(). It always selects a target CPU for the inserted
thread, now. If no CPU is idle, the CPU running the thread with the lowest
priority is chosen. If the thread running on the target CPU has a lower
priority than the inserted one, it will be asked to reschedule. If that's
the current CPU, we'll return the correct value (wasn't done before at
all).
These changes help reducing latencies. On my machine in an idle system
playing music DebugAnalyzer shows maximum latencies of about 1 us. I still
find that a bit much, but it's several orders of magnitude better than
before. The -j8 Haiku image build time dropped about 10%.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34635 a95241bf-73f2-0310-859d-f6bbb57e9c96
implemented by means of an additional member in cpu_ent.
* Removed thread::keep_scheduled and the related functions. The feature
wasn't used yet and wouldn't have worked as implemented anyway.
* Resurrected an older, SMP aware version of our simple scheduler and made it
the default instead of the affine scheduler. The latter is in no state to
be used yet. It causes enormous latencies (I've seen up to 0.1s) even when
six or seven CPUs were idle at the same time, totally killing parallelism.
That's also the reason why a -j8 build was slower than a -j2. This is no
longer the case. On my machine the -j2 build takes about 10% less time now
and the -j8 build saves another 20%. The latter is not particularly
impressive (compared with Linux), but that seems to be due to lock
contention.

accessible from the outside.
* Instead, request_data now retrieves/releases a reply port on its own.
* There were some more places that still used write_port()/read_port() instead
of QueryServer().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34597 a95241bf-73f2-0310-859d-f6bbb57e9c96
usual structures.
* Also, they now use the QueryServer()/SendToServer() functions instead of
duplicating them.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34596 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed at least two reference counting problems, but nodes from killed teams
still remain alive (will look into this at a later point).
* GetLiveNodes() is now using transfer_area() as well.
* Made all sizes in the SendTo*() and Query*() functions size_t.
* Replaced reinterpret_casts with static_casts when casting void pointers.
* Ordered the request/reply structures by target.
* Tried to consolidate the use of add_on vs. addon.
* More cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34591 a95241bf-73f2-0310-859d-f6bbb57e9c96
look into this now.
* Renamed the MMediaFilesManager to MediaFilesManager.
* Got rid of its Map usage, we're using std::map now instead.
* The media_server is using an unsafe method to transfer areas from the server
to the client. I've changed this for the BMediaFiles API to use Haiku's new
transfer_area() function. However, this seems to cause the above mentioned
problems.
* Improved naming and data exchange structures used for the BMediaFiles API.
* Fixed BMediaFiles leaking its lists.
* Cleanup.

system_time_nsecs(), returning the system time in nanoseconds. The function
is only really implemented for x86. For the other architectures
system_time() * 1000 is returned.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34543 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Renamed global variable _DormantNodeManager to gDormantNodeManager.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34538 a95241bf-73f2-0310-859d-f6bbb57e9c96
waits for certain events on a given page, NotifyPageEvents() wakes up
waiting threads respectively.
* Used the new feature instead of condition variables for waiting on busy
pages. We save publishing and unpublishing of a condition variable whenever
a page is marked busy. There's only something to do, if there's at least
one thread waiting in the list of the respective cache. The general
assumption is that this is only rarely the case and even if it happens,
there should be only very few threads.
* Added an apparently missing notification in cache_io(). At least I didn't
see the reason for it not being there.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34537 a95241bf-73f2-0310-859d-f6bbb57e9c96
to clarify that they never enlarge the area.
* Reimplemented VMKernelAddressSpace. It is somewhat inspired by Bonwick's
vmem resource allocator (though we have different requirements):
- We consider the complete address space to be divided into contiguous
ranges of type free, reserved, or area, each range being represented by
a VMKernelAddressRange object.
- The range objects are managed in an AVL tree and a doubly linked list
(the latter only for faster iteration) sorted by address. This provides
O(log(n)) lookup, insertion and removal.
- For each power of two size we maintain a list of free ranges of at least
that size. Thus for the most common case of B_ANY*_ADDRESS area
allocation, we find a free range in constant time (the rest of the
processing being O(log(n))) with a rather good fit. This should also
help avoiding address space fragmentation.
While the new implementation should be faster, particularly with an
increasing number of areas, I couldn't measure any difference in the -j2
haiku build. From a cursory test the -j8 build hasn't tangibly benefitted
either.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34528 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Renamed to AVLTreeBase and moved it into its own header/source file.
- Renamed FindClose() to FindClosest().
- Added CheckTree() method for debugging purposes. It checks the validity
of the tree.
* Added a templatized class AVLTree which doesn't offer a map-like interface
like AVLTreeMap, but rather one similar to BOpenHashMap and SplayTree. It
is more convenient to use, if one wants to store objects that already
contain the key.

each buffer, and once for each buffer group.
* Also, SharedBufferList::Get() now gets the area to clone from itself, if
necessary, the caller no longer has to provide it.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34502 a95241bf-73f2-0310-859d-f6bbb57e9c96
into smaller parts:
media_addon_server:
* Removed (broken) use of (broken and inefficient) home-brewn Map, and List
classes. This also fixes a crash on shutdown when used with the malloc_debug
implementation. It's using stl::vector, and stl::map now instead.
_shared_buffer_list:
* Renamed _shared_buffer_list to SharedBufferList, and put it into the BPrivate
namespace. Also, made a class out of it.
* Separated shared buffer list creation from cloning.
* Enlarged maximum number of buffers to something that is not that evil, but
actually uses the space it has (ie. is a useful multiple of
shared_buffer_info that fills a multiple of B_PAGE_SIZE as much as possible).
* No longer drops into the debugger if the
* The list that is currently used is very inefficient for the features it
provides though (no change there).
_buffer_id_cache:
* Renamed to BufferCache, and put it into the private namespace
* It now deletes its buffers on deletion; since the BBufferConsumer will be
gone, too, at this point, there is little chance that there are still buffers
in use.
* Also, it's now using std::map instead of the (see above) Map class.
BBuffer:
* Got rid of the fBufferID member.
Misc.:
* Got rid of the global "team" variable; the media kit is now using the
private app kit's current_team() now.
* Added a lot of missing error checks (mostly memory allocations).
* Renamed fields like "flavorid" to flavor_id, renamed "dfi_*" fields to
something more detailed.
* Moved ServerInterface.h from src/servers/media/ to headers/private/media.
* Notifications.h was not self contained.
* Added missing licenses.
* Lots of cleanups, and coding style fixes.
What this doesn't fix:
* Bug #4954 which started all this (this comes next, though)
* Deinitialization is broken, as the PortPool is uninitialized too early, and
still used afterwards.
* The strange add-on monitoring code in the media_addon_server

link to them.
* VM{Kernel,User}AddressSpace manage the respective VMArea subclass now, and
VMAddressSpace has grown factory methods {Create,Delete}Area.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34493 a95241bf-73f2-0310-859d-f6bbb57e9c96

identical, but that will change.

and size.
* Made VMArea::Set{Base,Size}() private and made VMAddressSpace a friend.
In vm.cpp the new VMAddressSpace::ResizeArea{Head,Tail}() are used
instead.
Finally all address space changes happen in VMAddressSpace only. *phew*
Now it's ready to be thoroughly butchered. :-)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34467 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Instead, added a new function is_local_link_address() which returns the
interface with the matching link level address, and can additionally test
for unconfigured interfaces.
* Merged the two versions of fill_sockaddr_in() together in ipv4.cpp.
* ipv4 now uses the new is_local_link_address() function to figure out whether
the received packet should be processed or not. This should fix a few DHCP
issues with multiple and configured interfaces as recently explained on the
mailing list.

simplify migration of the area management, but as a side effect, it also
makes area deletion O(1) (instead of O(n), n == number of areas in the
address space).
* Moved more area management functionality from vm.cpp to VMAddressSpace and
VMArea structure creation to VMArea. Made the list and list link members
itself private.
* VMAddressSpace tracks its amount of free space, now. This also replaces
the previous mechanism to do that only for the kernel address space. It
was broken anyway, since delete_area() subtracted the area size instead of
adding it.
* vm_free_unused_boot_loader_range():
- lastEnd could be set to a value < start, which could cause memory
outside of the given range to be unmapped. Haven't checked whether this
could happen in practice -- if so, it would be seriously unhealthy.
- The range between the end of the last area in the range and the end of
the range would never be freed.
- Fixed potential integer overflows when computing addresses.

into methods, made all attributes (but "areas") private, and added
accessors.
* Also turned the vm.cpp functions vm_area_lookup() and
remove_area_from_address_space() into VMAddressSpace methods. The rest of
the area management functionality will follow soon.

CreateAsmStructOffsetsHeader mechanism to generate a header with macros
defined to the sizes of the structures we're interested in and when compiling
in C mode define the structures as "struct { char bytes[size]; }".
It works in principle, but due to how jam works, one would have to specify the
dependency to the generated header for all sources that include it directly or
indirectly.

another invocation of InitializeDefault() could theoretically initialize the

* The kernel backend for faccessat() does not yet differentiate between

abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

checking the physical frame buffer location.
* This allows us to map the whole frame buffer at once, which means there is no
need anymore to remap the memory on mode change.
* Also, this will ease the burden of the MTRRs, as the memory size will be
properly aligned.

all MTRRs at once.
* Added a respective x86_set_mtrrs() kernel function.
* x86 CPU module:
- Implemented the new hook.
- Prefixed most debug output with the CPU index. Otherwise it gets quite
confusing with multiple CPUs.
- generic_init_mtrrs(): No longer clear all MTRRs, if they are already
enabled. This lets us benefit from the BIOS's setup until we install our
own -- otherwise with caching disabled things are *really* slow.
* arch_vm.cpp: Completely rewrote the MTRR handling as the old one was not
only slow (O(2^n)), but also broken (resulting in incorrect setups (e.g.
with cachable ranges larger than requested)), and not working by design for
certain cases (subtractive setups intersecting ranges added later).
Now we maintain an array with the successfully set ranges. When a new range
is added, we recompute the complete MTRR setup as we need to. The new
algorithm analyzing the ranges has linear complexity and also handles range
base addresses with an alignment not matching the range size (e.g. a range
at address 0x1000 with size 0x2000) and joining of adjacent/overlapping
ranges of the same type.
This fixes the slow graphics on my 4 GB machine (though unfortunately the
8 MTRRs aren't enough to fully cover the complete frame buffer (about 35
pixel lines remain uncachable), but that can't be helped without rounding up
the frame buffer size, for which we don't have enough information). It might
also fix#1823.

- Rename "Configure Favorites..." to "Edit Favorites...".
- Remove the old-style Configure Favorites dialog in favor of simply
opening the favorites folder (~/config/settings/Tracker/go) in a
Tracker window for the user to manipulate.
- Rename the "Favorite Folders" section to simply "Favorites" as files
are also allowed (i.e. to easily open a template document).
- Removed completely arbitrary (and silent) 20 item limit to favorites
list.
- Automatic whitespace cleanup
Still to do: Grab the ref filter from the file panel (if any) and run the
favorites through it as well, since we want to filter out any non-folder
favorites that the app is incapable of handling. Also, the setting for
the favorites menu to show recent documents needs a new home, as it was
previously in the no longer existing Configure Favorites window. Suggestions
welcome, as I'm not currently seeing a spot in the Tracker prefs that would
make good sense.

* When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is
held longer than DEBUG_LATENCY micro seconds (currently 200). If your system
doesn't boot anymore, a new safemode setting can disable the panic.
* Besides some problems during boot when the MTRRs are set up, 200 usecs work
fine here if all debug output is turned off (the output stuff is definitely
problematic, though I don't have a good idea on how to improve upon it a lot).
* Renamed the formerly BeOS compatible safemode settings to look better; there
is no need to be compatible there.

(hopefully) correct place.
* It seems to be even harder to understand basic locking primitives: when you
think about it, it shouldn't surprise you that conditional variables never
return B_WOULD_BLOCK. This fixes gdb again.
* Added tracing support to the ports subsystem.
* get_port_message() will now resize the port heap if needed (but will also
take timeouts into account while doing so, more or less). The initial port
space is 4MB (as before), the growth rate is the same, and the system wide
limit is arbitrarily set to 64 MB (all swappable). A team limit has been set
to 8 MB, but is not enforced yet. Since ports are using up address space in
the kernel, those seems to be proper limits.
* This also fixes a strange, and rare lockup where the mouse cursor would still
move, but everything else would basically hang, but look perfectly normal from
KDL on the first look. As recently happened on Brecht's laptop, and debugged
by mmlr and me: the cbuf space got used up when lots of windows wanted to
redraw after a workspace switch. The app_server wouldn't answer anymore to
client requests, but thought it would have done so, as LinkSender::Flush()
doesn't care if it got a B_NO_MEMORY (the ports will now block until memory
is available if possible, so that should not be a problem anymore).
* Improved "port" KDL command, it now also prints the messages in the port.

therefore removed it from the kernel. The heap is swappable, so lifts the
kernel's resource usage a bit. In the future, the heap should grow as well;
right now it should be at least as good as before.
* it no longer uses spinlocks, but just mutexes now for better scalability - it
was not usable with interrupts turned off anyway (due to its semaphore usage).
* it no longer uses semaphores, but condition variables.

wasn't usable that early.

as the one from libkernelland_emu but uses a mutex per lock instead of emulating
a global thread lock. Also added MutexLocking and RWLock{Read|Write}Locking and
AutoLockers based on them. It's cased with __cplusplus so the locks are also
usable from C. Everything's currently exposed in shared/private/locks.h but I
think we should make these locking primitves public.

are required to be physically contiguos, which should be reworked to put them
into seperate iovecs. Still this manages to combine a great deal of page
writes into larger bursts already. Reduces the amount of IO requests being
scheduled (and greatly benefits media where page wise writes are slow when
they are accessed through a non-IOScheduler path, i.e. USB mass storage until
that is properly implemented).
* Abstracted per page page writing tasks into a PageWriteWrapper class.
* Abstracted per transfer page writing tasks into PageWriteTransfer class which
formerly was the PageWriterCallback.
* Use both classes from the PageWriterRun and from
vm_page_write_modified_page_range to remove code duplication.
* Adjusted synchronous VMAnonymousCache::Write() to cope correctly with larger
iovecs and more than one iovec. It assumed that there was exactly one page per
vector previously.
* Introduced MaxPagesPerWrite() and MaxPagesPerAsyncWrite() to VMCache to allow
a cache to specify restricitions. VMAnonymousCache does restrict the max pages
to 1 for WriteAsync right now as I didn't feel like reworking that one to cope
with non single page writes just yet.

importantly block until the operation is done (waiting for the reply).

Also fixed a type in the ScreenSaverRunner header.

* Added new header headers/private/system/disk_device_types.h, which defines
the <DiskDeviceTypes.h> constants as macros and which can be used where the
constants cannot be used. The constants are defined using the macros, so now
there's only one place where the string literals should be specified.
* Use the macros in the partitioning systems. I was too lazy to also adjust the
file systems -- most of them seem to hard-code the string literal yet.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33386 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Fixed vfs_get_vnode_from_fd() return type.
- Added vfs_open_vnode().
- Added a "bool traverseLeafLink" parameter to vfs_get_fs_node_from_path().
It was always resolving symlinks.
* device manager/devfs:
- devfs: get_node_for_path() no longer resolves leaf symlinks. That still
doesn't help with file disk devices, as creating partition wouldn't work
anyway.
- Pulled the module-related implementation part of BaseDevice into new class
AbstractModuleDevice and made all methods of BaseDevice virtual. Small
adjustments to devfs to be happy with the new BaseDevice interface.
- Added BaseDevice subclass FileDevice, which maps the interface to a file's
file descriptor. Still got a few TODOs, but should basically work.
- Use FileDevice for publishing file disk devices in devfs. Now those do
actually work, though there's some BFS trouble with one of the images I
tested.

Remove the 4 cores limit at boot, and fix the allocator to handle 8 cores.

- Removed passing the hpet_regs around, since there's a static variable.
- Added lots of debug dprintfs.

- Use the timer 0 instead of 2.

-Jamrule for collectcatkeys no longer print all the strings, only a message when it can't parse one (happens for TR(variable) basically)
-Added fingerprint check in the plaintext catalog ReadFromFile. However, the adler checksum is different each time the catalog is loaded because it relies on the string being iterated always in the same order, but this is not always the case with an HashMap ! Some rethinking is needed, so disabled the check for now so it does not breaks the build
-Some try to debug the bluetooth preflet localization. Still buggy, but I wanted to commit all this mess before I break everything up again.
-Also sorted the fr.catkeys files to be in the same order as the autogenerated en.catkeys (this is useless but makes them easier to check) and updated their fingerprint even if they are still not checked.
-Miscelaneous style fixes, small bugfixes, more error checking and error messages saying where they come from.

Maybe it's possible to even have both current Mesa Software Renderer add-on

Net_server starts services by invoking fork() followed by exec(). If the latter
fails (for instance because the service isn't installed), the forked child is
invoking exit(). This in turn unloads libbe, triggering static cleanup code in
BMessage, which deletes a couple of message ports that were inherited from the
parent during the fork. After that, net_server was desparately missing those
ports and no longer worked reliably.
* in InitTerminateLibBe, we now register an atfork-(child-)handler, which
takes care to re-initialize the static reply ports used by BMessage code
* added BMessage::Private::StaticReInitForkedChild wrapper and
BMessage::_StaticReInitForkedChild() implementation which overwrites the
inherited port IDs with a set of own ports

workspace activation message was asynchronous, whether or not the
BWindowScreen stopped drawing in time was pure luck (this also caused crashes
with the VESA driver, as that one unmaps its frame buffer during mode switch).
Introduced a new AS_DIRECT_SCREEN_LOCK protocol for this.
* In the long term, we should let BWindowScreen use the same mechanism as
BDirectWindows, though.
* Removed superfluous locking in BDirectWindow::_InitData().

* scheduler_enqueue_in_runqueue() now allows the scheduler to return a hint as to whether a reschedule is desirable or not. This is used in a few other places in order to relegate scheduling decisions entirely to the scheduler rather than the priority hacks previously used. There are probably other places in the kernel that could now make use of that information to more intelligently call reschedule() though.
* Switch over the default scheduler to scheduler_affine().

make it work, one would need to use versioning for all libbe symbols. This is
worth an 8k price per file that links against libbe.so, so I didn't want to
commit this as is. An alternative to this solution would be to write a
separate application that is responsible for the app_server's window. Comments
welcome.
* Removed BeOS compatbility of the libbe_test stuff.
* Renamed the libbe_test targets from *haiku* to *test*, ie. libbe_haiku.so is
now called libbe_test.so, haiku_registrar is now test_registrar, etc.
* This also removes BeOS compatibility from tracker/FSUtils.cpp (all BeOS
compatibility should be removed, but I don't want to make Alexandre more work
in his branch, and it's not urgent at all).
* Replaced the former "run" scripts for the test environment with a single
run script (see updated NOTES file).
* Removed the libbe_test target from some applications - this was only to help
developing them under BeOS, and is thus no longer necessary.

* Keep track of the currently running threads.
* Make use of that info to decide if a thread that becomes ready should preempt
the running thread.
* If we should preempt we send the target CPU a reschedule message.
* This preemption strategy makes keeping track of idle CPUs by means of a bitmap
superflous and it is therefore removed.
* Right now only other CPUs are preempted though, not the current one.
* Add missing initialization of the quantum tracking code.
* Do not extend the quantum of the idle thread based quantum tracking as we want
it to not run longer than necessary. Once the preemption works completely
adding a quantum timer for the idle thread will become unnecessary though.
* Fix thread stealing code, it did missed the last thread in the run queue.
* When stealing, try to steal the highest priority thread that is currently
waiting by taking priorities into account when finding the target run queue.
* Simplify stealing code a bit as well.
* Minor cleanups.

device is not compatible, after all.
* No longer accept color changes if the mode is not an 8 bit one. I think that
BWindowScreen does that after changing the mode, so that is messes up the
colors, at least that's the theory, will test on real iron now.
* Use VGA as a fallback if setting the palette via VBE failed. This brings back
the colors for ParticlesII in Qemu (but not in VirtualBox, which seems to be
completely broken in this regard).

* The vesa driver no longer uses VGA programming if the chip does not support
VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
the new vesa_set_indexed_colors() that is now used for palette programming.
This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
right now, the colors are garbled after a workspace switch. Stefano, are you
looking into that already?

* Fleshed out the Encoder API to support parameter setters/getters and returning
a BView for configuration. (Not yet sure if this is a good idea.)
BMediaTrack:
* Implemented all but one of the unimplemented methods in BMediaTrack. It should
be working as far as that class is concerned, unless I missed some of the
vision. ReplaceFrames() remains a stub, added a comment on why it probably
stays that way.
* Release the Encoder reference in the destructor.
FFmpeg plugin:
* Refactoring to delay opening the AVCodec until encoding the first chunk,
so that we can still adjust parameters.
* Support adjusting parameters via [Set|Get]EncodeParameters(). Currently,
only quality is supported, added TODOs about supporting the bit_rate setup
versus the automatically calculated bit_rate.
* Extended EncoderDescription by a bit_rate scale. The Encoder calculates the
raw bitrate needed by the current media format, and then divides that
number by the specific codec's bit_rate_scale, while taking into account the
desired quality. This seems to work very well already (tested with MPEG4),
although a lot more parameters could be specified for libavcodec, depending
on the desired quality.
* Enabled the ogg muxer in libavformat, although it is currently still disabled
in MuxerTable.cpp, because it rejects unknown codecs. Added TODO to this
effect.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32124 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The BView API can probably be regarded as good enough; the implementation
might need to be improved over time (also, some things as archivability
aren't fully implemented yet). The ToolTip.h header should get public once
finalized.
* Added new B_MOUSE_IDLE message that is sent to a BView after a certain
time has passed (BToolTipManager::ShowDelay()).
* Added small test app (ToolTipTest) that shows what is already working.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32078 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added some multiboot support code:
- dump some of the passed info,
- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32076 a95241bf-73f2-0310-859d-f6bbb57e9c96
allow for more parallelism. Also introduce seperate locks for the bins and
for page allocation. This greatly reduces lock contention and reduces the
duration the locks are held due to them overall protecting less code. Now only
allocations of the same size hitting the same allocator or allocating larger
chunks of memory should block. Previously, basically any allocation and also
free would be mutually exclusive, making it scale pretty badely.
* Added memalign_nogrow(). As it uses heap_memalign() anyway, there's no real
reason not to allow for an alignment.
* Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32074 a95241bf-73f2-0310-859d-f6bbb57e9c96
ROUNDUP to use '*' and '/' -- the compiler will optimize that for powers of
two anyway and this implementation works for other numbers as well.
* The thread::fault_handler use in C[++] code was broken with gcc 4. At least
when other functions were invoked. Trying to trick the compiler wasn't a
particularly good idea anyway, since the next compiler version could break
the trick again. So the general policy is to use the fault handlers only in
assembly code where we have full control. Changed that for x86 (save for the
vm86 mode, which has a similar mechanism), but not for the other
architectures.
* Introduced fault_handler, fault_handler_stack_pointer, and fault_jump_buffer
fields in the cpu_ent structure, which must be used instead of
thread::fault_handler in the kernel debugger. Consequently user_memcpy() must
not be used in the kernel debugger either. Introduced a debug_memcpy()
instead.
* Introduced debug_call_with_fault_handler() function which calls a function
in a setjmp() and fault handler context. The architecture specific backend
arch_debug_call_with_fault_handler() has only been implemented for x86 yet.
* Introduced debug_is_kernel_memory_accessible() for use in the kernel
debugger. It determines whether a range of memory can be accessed in the
way specified. The architecture specific back end
arch_vm_translation_map_is_kernel_page_accessible() has only been implemented
for x86 yet.
* Added arch_debug_unset_current_thread() (only implemented for x86) to unset
the current thread pointer in the kernel debugger. When entering the kernel
debugger we do some basic sanity checks of the currently set thread structure
and unset it, if they fail. This allows certain commands (most importantly
the stack trace command) to avoid accessing the thread structure.
* x86: When handling a double fault, we do now install a special handler for
page faults. This allows us to gracefully catch faulting commands, even if
e.g. the thread structure is toast.
We are now in much better shape to deal with double faults. Hopefully avoiding
the triple faults that some people have been experiencing on their hardware
and ideally even allowing to use the kernel debugger normally.

- stubbed out arch_cpu_init_percpu(),
- make atomic ops declarations extern "C",
- move calls to [i]sync inside the asm code that needs it.

* SMP:
- Added smp_send_broadcast_ici_interrupts_disabled(), which is basically
equivalent to smp_send_broadcast_ici(), but is only called with interrupts
disabled and gets the CPU index, so it doesn't have to use
smp_get_current_cpu() (which dereferences the current thread).
- Added cpu index parameter to smp_intercpu_int_handler().
* x86:
- arch_int.c -> arch_int.cpp
- Set up an IDT per CPU. We were using a single IDT for all CPUs, but that
can't work, since we need different tasks for the double fault interrupt
vector.
- Set the per CPU double fault task gates correctly.
- Renamed set_intr_gate() to set_interrupt_gate and set_system_gate() to
set_trap_gate() and documented them a bit.
- Renamed double_fault_exception() x86_double_fault_exception() and fixed
it not to use smp_get_current_cpu(). Instead we have the new
x86_double_fault_get_cpu() that deducts the CPU index from the used stack.
- Fixed the double_fault interrupt handler: It no longer calls int_bottom to
avoid accessing the current thread.
* debug.cpp:
- Introduced explicit debug_double_fault() to enter the kernel debugger from
a double fault handler.
- Avoid using smp_get_current_cpu().
- Don't use kprintf() before sDebuggerOnCPU is set. Otherwise
acquire_spinlock() is invoked by arch_debug_serial_puts().
Things look a bit better when the current thread pointer is broken -- we run
into kernel_debugger_loop() and successfully print the "Welcome to KDL"
message -- but we still dereference the thread pointer afterwards, so that we
don't get a usable kernel debugger yet.

info is not part of the media_format otherwise.
* Finished enough in the AVFormatWriter and AVCodecEncoder that we can now
actually create AVIs and MPGs and encode MPEG1, MPEG2 and MPEG4 video.
But no audio as of yet. Also, there is no bit-rate/quality setup, so it seems
libavformat is using the least possible bit-rate/quality.
* Enable some more muxers and encoders in the FFmpeg libs.
* Uses pixel format conversion from libswsscale, need to read the documentation
again, but I think it makes the plugin GPL.
* Fixed includes in libswscale/swscale.h, this is now an unmodified FFmpeg 0.5
header again (AFAICT).

storage.
* Remove reduntant information from the header (field_count vs. fields_size).
* Remove checksums previously used to validate the message passing by area
mechanism.
* Move variables that are purely used by the instance out of the header and into
the BMessage object.
* Use more sensible types for the different message fields.
* Reduce some field sizes to realistic values.
* Make size_t values into uint32 values so the message format will not change
when later moving to 64 bits.
* Pack the structures used for flat message storage so it doesn't change
because of padding.
* Fix message passing by area. It never worked because the created area was
never actually filled with any data!
* Some more allocation checks with graceful fallbacks (should be all now).
* Some more checks for negative index values (should also be all now).
* Make printing more inline with how the rest of the class works and make some
of the output more consistent.
* Also add the new unsigned types to PrintToStream() output.
* Fix printing of unknown types and invalid BMessages, it would always have
printed only the first entry respectively the same error.
* Added some clarifying comments.
* Cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32039 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added x86_double_fault_get_cpu(), a save way to get the CPU index when in
the double fault handler. smp_get_current_cpu() requires at least a somewhat
intact thread structure, so we rather want to avoid it when handling a double
fault. There are a lot more of those dependencies in the KDL entry code.
Working on it...

media_file_format as input, so that the Writer knows what kind of file is
needed.
* Also, since information about the stream format is going to be needed at the
Writer level as well, the AllocateCookie() method gets the stream
media_format.
* Fleshed out some aspects of AVFormatWriter, many TODOs are left.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32025 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Improved Encoder API towards what we need for the get_next_encoder() variants
and the BMediaTrack API.
* Implemented the rest of MediaWriter. Still undecided what to make of
AddTrackInfo(). BMediaEncoder has that as well, which hints that this is
something the Encoder needs to support. But it could also be that this is
only possible to support in Writer.
* Wired a lot of previously unimplemented methods in BMediaFile and BMediaTrack
needed for write support. If I have not overlooked anything, only the

This is all untested, since the FFMpeg Encoder and Writer are still only stubs.

The AddOnManager in the media_server registers one encoder entry per
successful EncoderPlugin::RegisterNextEncoder(). This gives us a first idea
what media_format_family and input/output media_type is supported. The
mechanism may have to be extended, or the Encoder needs an API to specialize
a format further. In that case, the get_next_encoder() version that takes
optional _acceptedInput/OutputFormat needs to instantiate the plugin and
needs to ask the Encoder. But AFAIK, no app uses it like that anyway.

in PluginManager is reenabled. We use the media_codec_info.id to reference
a specific plugin, while the sub_id will be used to reference individual
Encoders that the plugin supports. No idea if that's how it was intented, but

comments are of course very welcome on any of these commits, as always.

* Renamed the new Haiku call fs_open_attr() to fs_fopen_attr(), and added a new
function fs_open_attr() that takes a path (same semantics as the
fs_[f]open_attr_dir() functions already present in BeOS).

there are prefixed with the respective architecture name. Useful for remote
debugging a different architecture.
* <x86/arch_debugger.h>: Introduced a structure for the FPU state, so that it
isn't left to the debugger.
* Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for
bdb compatiblity, but isn't really needed.
* Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since
it reinits the FPU after saving the state. This resulted in weird results
when debugging functions using the FPU. We now use fxsave, if available.
Otherwise fnsave + frstor should be used -- not fully implemented yet.
Same for arch_set_debug_cpu_state().

patch from about a year ago (I couldn't use any code of his yet, though,
but there are a few things left). The emergency keys are triggered by
pressing Alt-SysReq + key.
* By default, only Alt-SysReq+'d' is used as a means to deliberately enter
the kernel debugger. F12 belongs to userland again, now :-)
* Debugger add-ons now have another optional method to implement their own
emergency keys - 'd' for the debugger cannot be overridden, though.
* The mechanism can be turned off via a new kernel setting, so it's not that
easy anymore to "crash" Haiku if you don't want to.
* Right now, the PS/2 driver, and the pre-input_server in-kernel debugger
keyboard mini-driver support this, USB not yet.
* Minor cleanup.

* Added missing name parameter to the partitioning system module child creation
and child creation validation hooks. Pass the name to them.
* Added BPartitionParameterEditor interface, which is/will be used for editing
disk system specific parameters.
* Implemented partition parameter editors for BFS initialization and Intel
partition map child creation.
* Fixed the incorrect supported child partition type iteration in the Intel
partition map add-on. It does now return actual types.
* Handle the "active" flag parameter in the Intel partitioning system module.
* DriveSetup:
- Replaced the "Create" submenu by a simple menu item. The type can now by
chosen in the dialog.
- Make use of initialization and child creation parameter editors. Some
non-generic code has been moved to the respective editor implementations
(BFS, intel partitioning system).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31658 a95241bf-73f2-0310-859d-f6bbb57e9c96

* devfs:
- devfs_[un]publish_partition(): They no longer get the partition path as
parameter, but rather the device path and the partition name.
- Added devfs_rename_partition(), which renames an already published
partition node.
* KPartition/KDiskDevice:
- Replaced the fPublished flag by fPublishedName, the name under which the
partition is published. This simplifies UnpublishDevice() and makes it
practically infallible.
- Added GetFileName(), which only returns the partition's file name.
Simplified GetPath() by using it.
- When a partition is added/removed the subsequent sibling partitions get a
new index. Now we also rename their published device nodes (and those of
their descendents). When something goes wrong we unpublish the concerned
partition's device to be on the safe side. Would be a shame to accidentally
format the wrong partition, eh? :-)

* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
not running thread. Introduced arch_get_thread_debug_cpu_state() for that
purpose, which is only implemented for x86 ATM (uses the new
i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
after a instruction breakpoint debug exception. This should prevent
breakpoints from being triggered more than once (e.g. when the breakpoint is
on an instruction that can cause a page fault). I still saw those with bdb
in VMware, but that might be a VMware bug.

which are set when the PluginManager hands out new instances. This way the
manager knows what plugin created the Decoder or Reader instance in the
Destroy*() methods and can decrease the reference count accordingly. Also added
some FBC stuffing to Decoder and Reader. All media plugins need to be recompiled,
in case anyone has some outside the Haiku tree.

stupid use of the write overlay (just saw this happening on an older

this was writable, and this also avoids casting away the const when adding
the default swap file.

- While walking down the cache chain, we keep all upper caches locked.
- When we have to unlock -- when waiting for a busy page or reading a page in
-- we unlock completely, including the address space, and restart
vm_soft_fault().
- Folded fault_get_page() and fault_find_page() into one.
This simplifies and improves things considerably:
- We no longer need dummy pages.
- We no longer need vm_area::no_cache_change.
- #2710 is fixed, since we no longer hold the address space lock while
waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
is already mapped at the address. If it is already our page, we just change
its protection. If not, we unmap it first. Fixes race conditions when multiple
threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
vm_translation_map::protect() call.

gcc could apparently assume that the register assigned to the one in the
clobber list would keep its value (as can be observed when disassembling
add_debugger_command_etc()).
Using a dummy output register works around the problem and also avoids the
unnecessary initialization of the register.
Comments explaining the mystery welcome.

the syscall. Anything beyond st_mtim was therefore not filled in. Fixes
the incorrectly shown creation times in Tracker.
* The BStatable::GetStat() solution was not sufficient yet. We still have to
provide the old GetStat() symbol for BNode and BEntry, since those could be
used by old applications/libraries. We also still have to implement the old
GetStat() slots in the derived classes, but don't need to implement it in
the base class (was purely virtual before and is private now).
* The old BStatable::_OhSoStatable1() slot function was not implemented
correctly. Calling the virtual function at the vtable slot obviously results
in an infinite recursion. The correct implementation would make use of the
Perform() method, but Be didn't provide one for BStatable, so we have to use
the old GetStat() method. Fixed#3960.

separate the two stacks.
* Continued renaming stuff in drivers/bus/ATA.h
* Make all the busses/ata drivers include the new headers,
specifically ata_types.h, ata_adapter.h and bus/ATA.h,
they were all including ide_types and bus/IDE.h still
* Some renaming of global variables for coding style consistency
* Removed the promise driver from the build, it's not used on the
image and I don't believe it compiled even for the old IDE stack.
* There is no more Command Queueing in the new ATA stack, so I
removed the capability indication from the busses/ata drivers
and ata_adapter.h.
The new ATA stack still boots fine on my computer and I proof-read
the diff like two times. Basically, this was a careful search&replace
job only. The only things I am not sure about is renaming some
publishing related strings, but it seems to all work fine.

* Implemented a way to do asynchronous pre-fetching when mapping files.
* There are slight code duplications in some places that could benefit
from cleaning up, but nothing too bad.
* Implementing smarter ways to trigger prefetching and more analysis of
the situations in the kernel would be nice. Currently up to 10 MB
of every mapped file are pre-fetched without further analysis.
* The speed improvement is nice for certain operations. On our test
system (real hardware), Firefox took 9 seconds from being launched
to display a window. Now it takes 5 seconds. Both measurements
right after booting. The same system took 35 seconds from launching
Haiku in the GRUB menu to displaying the Tracker desktop background
image. Now it takes 27 seconds.

CD boot, but potentially, they could speed it up a lot.

socket could be acquired, ie. when its reference count is 0, it cannot be
acquired anymore. This requires the protocol to do proper locking, though.
* The TCP EndpointManager now checks the return value of acquire_socket(), and
only returns the endpoint if that succeeded.
* This fixes bug #2197.
* Minor cleanup.

- Moved scheduler listening interface to <listeners.h> and added more
convenient to use templatized notification functions.
- Added a listener mechanism for the wait objects (semaphores, condition
variables, mutex, rw_lock).
* system profiler:
- Hopefully fixed locking issues related to notifying the profiler thread
for good. We still had an inconsistent locking order, since the scheduler
notification callbacks are invoked with the thread lock held and have to
acquire the object lock then, while the other callbacks acquired the object
lock first and as a side effect of ConditionVariable::NotifyOne() acquired
the thread lock. Now we make sure the object lock is the innermost lock.
- Track the number of dropped events due to a full buffer.
_user_system_profiler_next_buffer() returns this count now.
- When scheduling profiling events are requested also listen to wait objects
and generate the respective profiling events. We send those events lazily
and cache the infos to avoid resending an event for the same wait object.
- When starting profiling we do now generate "thread scheduled" events for
the already running threads.
- _user_system_profiler_start(): Check whether the parameters pointer is a
userland address at all.
- The system_profiler_team_added event does now also contain the team's name.
* Added a sem_get_name_unsafe() returning a semaphore's name. It is "unsafe",
since the caller has to ensure that the semaphore exists and continues to
exist as long as the returned name is used.
* Adjusted the "profile" and "scheduling_recorder" according to the system
profiling changes. The latter prints the number of dropped events, now.

* strlcpy() isn't a particularly good string compare function.

BDebugEventOutputStream.

* One can now select which system profiling events one is interested in.

much the ones recorded when scheduler tracing is enabled. Still missing are
the "wait object" events that allow to interpret what a thread is waiting
for.

a "flags" field for the same purpose.
* Renamed protected DefaultNotificationService methods (removed "_" prefix).
* Adjusted the code providing a notification service accordingly.
* Changed the event message several notification services generated by renaming
the "opcode" field to "event".
* Implemented the TEAM_ADDED event and also added a TEAM_EXEC event.

kits/shared since i plan to use it in other places like Tracker. Animated replicants like
ActivityMonitor wont stall anymore when initiating the drag. (On the desktop, Tracker's mouse
tracking still busy loops sometimes, that's next on my list).
I had asynchronous long click detection (one button mouse support) in it but decided to get rid of
it, it adds unneeded complexity in the code and is even getting in your way sometimes (ex: now you can
take your time to drag the dragger, you wont be interrupted). If we want to reimplement that
someday it should be done system wide anyway (only Tracker and replicants have that 'feature'
AFAIK).

the protocoll less prone to errors, reduces possible points of failure and
most importantly, reduces the number of function calls to the link API.
I only know the numbers for StrokeLine(), which I tested via the Benchmark
test app. With this change, drawing random colored and positioned lines
actually doubled in speed. On the BView side, the calls to
ServerLink::Attach() only halfed, while on the app_server side, the number
of calls to ServerLink::Read() is now 1/4th. It will also be worth
investigating why the link stuff is so slow at all. I also optimized
BView::DrawString() a lot in this change, but I don't have any numbers
yet. Some other commands which used multiple Attach()/Read() calls were
also optimized, at least the most important ones. Begin/EndLineArray() was
also pretty bad on the app_server side.

KernelRequest which has respective attributes.
* Server: RequestThreadContext does now also save the request that is being

We do some caching using a hash table indexed by the operations vector.
* Pass the vnode capabilities to the kernel module.
* In the kernel tailor the operation vectors for volumes and vnodes passed to
the VFS according to the respective capabilities. This way those vectors look
pretty much like those from the client FS. This saves unnecessary calls when
hooks are not implemented and should also fix compatibility problems in cases
where not implementing a hook and returning an error don't mean the same to
the VFS.
* Inlined some of the kernel module Volume class getters.

- Send() now also gets the message to send as parameter.
- Added methods to reserve and unreserve space in the buffer.
* RequestAllocator: Uses the port buffer reservation methods now. This allows

* Change Port::Receive() semantics. It does no longer use the buffer associated
with the object. Instead it allocates heap memory for the caller. Since
there's only one caller who clones the message anyway, we save one copy this
way (though we have an additional syscall in userland) and don't overwrite
a request being prepared for sending.
* Changed RequestAllocator::ReadRequest() to also read the request from the
port.

/system/servers, now.
* Got rid of the dispatcher application. It was the entity the kernel module
talked to when mounting a yet unknown FS. It started the client FS server
applications. Now the kernel module starts them directly. They use
respectively named ports, so the kernel module can find them when already
running.

* The I/O context related vfs_*() functions have io_context* instead of void*
parameters/return values, now.
* vfs_new_io_context(): Lock the parent I/O context before getting its table
size. Otherwise the table size could change until we do.
* vfs_resize_fd_table(): Fixed use of MutexLocker. We created only a temporary
object, not one with function scope.
* Renamed load_image_etc() to load_image_internal() and added a parameter for
specifying the parent team of the one to create.
* Introduced a kernel private load_image_etc() with a few more arguments than
load_image().

volume, and the vnodes, since we have three independent FS interface
structures, now. The latter is not supported in the kernel add-on, yet.
* Server:
- Temporarily removed some things from the build (the BeOS interface
and the cache implementations).
- Some WIP in HaikuKernelVolume and [haiku_]kernel_emu.{h,cpp}.
- Added HaikuKernelNode, which wraps fs_vnode for the client FS.
The server is still quite a bit away from being buildable again.

* Extended the debugger message for B_DEBUGGER_MESSAGE_HANDED_OVER by the
causing thread.
* Also send B_DEBUGGER_MESSAGE_HANDED_OVER to the debugger to which the team
was handed over. The message will be the very first one the debugger gets
from the team in question.
* Some harmless refactoring (added thread_hit_serious_debug_event()).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29302 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.
This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.
Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.
On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.
Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

the changes to the other filesystems.

It causes the interrupt handler to be inserted at the very end of the list
instead of at the top. It is intended to be used as a workaround when a
interrupt handler cannot know if it actually handled the interrupt. This
should never be used by native drivers. Also if we know that the result is
not valid because of this flag we won't disable the vector in case we count
many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
instead of the doubly linked one used with insque and remque as it greatly
simplifies things for such an easy use case and is more compact.

node. That is needed for a layered filesystem to be able to construct a full
fs_vnode out of a volume/inode pair.
* Adapt places where get_vnode is used. Sadly this is a C API and we can't just
use a default NULL for that argument.
* Introduce a flag B_VNODE_WANTS_OVERLAY_SUB_NODE that can be returned in the
flags field of a fs get_vnode call. A filesystem can use this flag to indicate
that it doesn't support the full set of fs features (attributes, write support)
and it'd like to have unsupported calls emulated by an overlay sub node.
* Add a perliminary overlay filesystem that emulates file attributes using files
on a filesystem where attributes aren't supported. It does currently only
support reading attributes/attribute directories though. All other calls are
just passed through to the super filesystem.
* Adjust places where a HAS_FS_CALL() is taken as a guarantee that the operation
is supported. For the overlay filesystem we may later return a B_UNSUPPORTED,
so make sure that in that case proper fallback options are taken.
* Make the iso9660 filesystem request overlay sub nodes. This can be fine tuned
later to only trigger where there are features on a CD that need emulation
at all.
If you happened to know the attribute file format and location you could build
an iso with read-only attribute support now. Note that this won't be enough to
get a bootable iso-only image as the query and index support is yet missing.

* Replaced the use of offsetof() for structs that aren't PODs. Add a
offset_of_member() macro to util/khash.h because that's what it's used for
in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
GCC > 2 to avoid the depricated conversion from string constants to char *.

it pointed out at least one bug that is fixed here as well.

- Default buffer size is now set to 1 instead of 0, which would cause the
construction without a given size to fail.
- Added copy constructor.
- Changed _GrowToFit() to have a boolean parameter to indicate if we want
to resize the buffer to an exact size. Used by the copy constructor.

This is a very welcome addition.
* There are a few issues, and maybe questionable decisions (like the dependence
on ACPI), but I see no reason why it shouldn't be added in its current form
already.
* Unfortunately, I could not test it yet, though, as the CPU of my laptop is
not supported; will see if I can find a supported hardware, though.

old invalid user listeners yet, though (ie. if a team dies).
* Implemented userland network monitor functions.
* Added a few notifications to the network stack, even though this part isn't
complete yet (especially notify_interface_changed()).
* Added optional debug output to the notifications module.
* Added the module to the image, it basically works now (tested).

* Compiles, but doesn't work at all yet. For those who wonder: the networking
notifications are put into a separate module, so that the network stack can
be unloaded without losing connection, IOW user applications will continue
to retrieve notifications when the stack is loaded again.

a message.
* The DesktopSettings class is now using that to send the new
AS_SYSTEM_FONT_CHANGED message to all windows.
* The ServerWindow now propagates font changes to its decorator, causing it
to update its drawing. That means changing the bold font in the "Fonts"
preferences application will instantly change all window titles.
* Factored out a _RebuildAndRedrawAfterWindowChange() out of several Desktop
methods, simplifying some code.
* The DefaultDecorator no longer calls _DoLayout() twice (through SetLook()),
but instead calls the new _UpdateFont() method now also called by
FontsChanged(), and SetLook().
* BWindow::GetDecoratorSettings() now also includes "tab frame" BRect with the
exact footprint of the tab, allowing apps to know the size of the tab to
position itself accordingly.
* Automatic white space cleanup.

the per-root-image breadth-first sorted image array. Instead we have a
per-image hook function to resolve the symbols. The default function
uses the sLoadedImages list directly, which is breadth-first sorted
anyway. There's also a BeOS function for old-style symbol resolution
and one for add-ons, which lacks a proper implementation yet (just
uses old-style ATM).
* Made the dl*() functions POSIX compliant:
- dlopen() does no longer use load_add_on(), but loads the object as a
library. It also properly supports a NULL name, now -- the previous
"_APP_" work-around did only work, if this soname was set on the
program (unlikely for programs using this API).
- Implemented RTLD_{GLOBAL,LOCAL}.
- dlsym() looks up symbols properly now, i.e. not just in the given
image, but breadth-first for an actual image or in load order for
the global scope. It also supports the not-quite POSIX RTLD_DEFAULT
and RTLD_NEXT extensions. Our RTLD_NEXT finds more symbols than in
Linux (also in later dlopen()ed libraries), but that should be fine.

gWidthBuffer.
* Tracker PoseView now uses BPrivate::gWidthBuffer instead of it's own
instance.
* TextView.h and PoseView.h are now a little cleaner.
* InterfaceDefs.cpp now deletes gWidthBuffer in _fini_interface_kit_().
* Added binary compatibility support for NetPositive in WidthBuffer.h and .cpp.
Obviously it kind of defeats the purpose of having WidthBuffer neatly tucked
away in the BPrivate namespace, but Haiku should run NetPositive, I guess.
Fixes#2879.

add-on) we create a breadth-first sorted image list and use that to

* Added support for preloading libraries. The environment variable
LD_PRELOAD can contain a whitespace-separated list of shared objects

This is not necessary, since userland teams' page directories also
contain the kernel mappings, and avoids unnecessary TLB flushes. To make
that possible the vm_translation_map_arch_info objects are reference
counted now.
This optimization reduces the kernel time of the Haiku build on my
machine with SMP disabled a few percent, but interestingly the total
time decreases only marginally. Haven't tested with SMP yet, but for
full impact CPU affinity would be needed.

scheduler_set_thread_priority(). Setting the thread priority was the
only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
an operation vector now, which is initialized at kernel init time.
This allows for picking the most suitable scheduler for the machine
(e.g. a non-SMP scheduler on a non-SMP machine).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28262 a95241bf-73f2-0310-859d-f6bbb57e9c96

added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
added respective functions to the vm_translation_map operations. The
architecture specific implementation can now decide how to implement
them most efficiently. Added generic implementations that can be used,
though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
Instead it returns an implementation-specific handle that has to be
passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
and *_debug() variants, that work only for the current CPU,
respectively when in the kernel debugger. Also adjusted the
vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
tree.
* Also adjusted the m68k and ppc implementations with respect to the
vm_translation_map operation changes, but they are probably broken,
nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
suboptimal in any case. For systems with small memory it is too much
overhead, since one can just map the complete physical memory (that's
not done yet, though). For systems with large memory it counteracts
the VM strategy to reuse the least recently used pages. Since those
pages will most likely not be mapped by the page mapper anymore, it
will keep remapping chunks. This was also the reason why building
Haiku in Haiku was significantly faster with only 256 MB RAM (since
that much could be kept mapped all the time).
Now we're using a different strategy: We have small pools of virtual
page slots per CPU that are used for the physical page operations
(memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
Furthermore we have four slots per translation map, which are used to
map page tables.
These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28244 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Introduced flag "invoke_scheduler" in the per CPU structure. It is
evaluated in hardware_interrupt() (x86 only ATM).
* Introduced SMP_MSG_RESCHEDULE_IF_IDLE message, which enters the
scheduler when the CPU currently runs an idle thread.
* Don't do dprintf() "CPU x halted!" when handling a SMP_MSG_CPU_HALT
ICI message. It uses nested spinlocks and could thus potentially
deadlock itself (acquire_spinlock() processes ICI messages, so it
could already hold one of the locks). This is a pretty likely scenario
on machines with more than two CPUs, but is also possible when the
panic()ing thread holds the threads spinlock. Probably fixes#2572.
* Reworked the way the kernel debugger is entered and added a "cpu"
command that allows switching the CPU once in KDL. It is thus possible
to get a stack trace of the thread not on the panic()ing CPU.
* When a thread is added to the run queue, we do now check, if another
CPU is idle and ask it to reschedule, if it is. Before this change, the
CPU was continuing to idle until the quantum of the idle thread
expired. Speeds up the libbe.so build about 8% on my machine (haven't
tested the full Haiku image build yet).
* When spinlock debugging is enabled (DEBUG_SPINLOCKS) we also record
the spinlock acquirer on non-smp machines. Added "spinlock" debugger
command to get the info.
* Added debugger commands "ici" and "ici_message", printing info on
pending ICI message respectively on a given one.
* Process not only a single ICI message in acquire_spinlock() and other
places, but all pending ones.
* Also process ICI messages when waiting for a free one -- avoids a
potential deadlock.
* Mask out non-existing CPUs in send_multicast_ici(). panic() instead of
just returning when there's no target CPU left.

* Fixed a general problem with respect to overriding of the reserved
virtual function slots: instead of statically invoking the method
that corresponds to the reserved slot on the class that contains the
slot, we now invoke the virtual Perform() method. Perform() then dispatches
the method invocation to the "proper" class, i.e. the highest class in the
hierarchy that actually implements the requested method.
This fixes a crash in apps that use liblayout's MSlider class and
should fix one or other spurious bug with old apps or libraries, too.
* added new header folder 'binary_compatibility' that contains files that
define the method codes and data structures required by Perform()
* looked for and implemented all used reserved virtual slot functions to
invoke Perform() where necessary or to pass on the method call statically
(for slots that were already maintained by Be)

BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.

* app_server/View can convert a BGradient layout to screen

* Instead, I followed Marcus' great idea and added a compatibility check in
the runtime loader: now, R5 binaries (also shared libraries) are detected,
and they get special versions for stat(), fstat(), and lstat() that return
the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
larger stat field for now, as this breaks some of our optional packages.
So until we rebuild them all, this shouldn't be enabled.

arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
vm_translation_map_arch_info indicating on which CPUs the address
space is active. This allows flush_tmap() to avoid ICI for user
address spaces when the team isn't currently running on any other CPU.
In this context ICI is relatively expensive, particularly since we map
most pages via vm_map_page() and therefore invoke flush_tmap() pretty
much for every single page.
This optimization speeds up a "hello world" compilation about 20% on
my machine (KDEBUG turned off, freshly booted), but interestingly it
has virtually no effect on the "-j2" haiku build time.

buffer format, the buffer can now also contain other events than just
stack traces. ATM these are only references to the image events
(created/deleted). Therefore we no longer have to flush the profiling
buffer after such an event, since the debugger can exactly match the
samples. Since we couldn't flush when the profiling timer hit while the
thread was in the kernel, that wasn't working that well anyway.
"profile -f" fails to translate stack trace addresses only very rarely,
now.

been mounted, before anyone could try to load any modules from it.
Also pass it a flag whether the boot volume is where the boot loader
pre-loaded the modules from.
* module_init_post_boot_device() changes the pre-loaded module image
paths to normalized boot volume paths, now. Got rid of the code in
register_preloaded_module_image() which tried something like this.
* Changed module image ref counting. A referenced module has single
reference to its image, which is released when the module becomes
unreferenced.
* get_module() for a reference module will not try to re-get and re-set
the module's image anymore. That could lead to a similar module (from
different paths) being loaded at the same time. A module from a new
file can only be loaded when the old one has been put completely.
* Simplified B_KEEP_ALIVE module handling a bit. When the module is
initialized, we add another reference, which we'll never free. Thus
the module remains loaded without special handling. Removed
module_image::keep_loaded. A B_KEEP_ALIVE module remains referenced
and thus its image remains referenced, too.
* Removed module::file, a cached path to the module's image. An
optimization that wouldn't work with multiple root directories for
modules (/boot/beos/..., /boot/common/...) or when module files were
moved. get_module() does now always search the image file, when the
module is still unreferenced. This should be a bit slower than before,
but I didn't notice any difference in VMware at least. If it turns out
to be a problem we could introduce a more intelligent cache that stays
up to date by using node monitoring.

before.
* Added "bool traverseLink" parameter to vfs_normalize_path(). When
true and the leaf component is a symlink, it will be resolved.
* KPath:
- Added similar leaf link traversal parameter to SetTo() and
SetPath().
- Added Normalize().
- Added DetachBuffer(), which returns the object's current buffer and
unsets itself.

* Extended the profiling API by an option to record a variable number of
samples per tick. The stack depth is used as a maximum.
* Added new option "-f" to the "profile" tool. When specified it
increments the hit counts of all symbols in the full available caller
stack. I.e. the resulting hit counts will approximate the total time
spent in each function or any function directly or indirectly called
by it. Thus "_start" and "main" will usually get 100% and leaf
functions only what time has actually been spent in them.

is a variably-sized structure with the small data region at the end.
Changed that to a ref-counted, shared member instead.

buffer during a timer event that interrupted a kernel function: We do
now flush the buffer as soon as it is 70% full, *if* we didn't interrupt
a kernel function. When the buffer runs full and we still haven't hit a
user function, we drop the tick. The number of dropped ticks is recorded
and sent to the debugger with the next update message.
Reverted the previous partial solution (the temporary disabling of
profiling while in debugger support code).

sent with several debugger messages.
* Track the image event counter that is used when samples are added to
the profiling buffer. If the current team counter differs, we flush
the buffer first (sending an update message to the debugger), so that
the debugger has a chance to match the addresses to the correct images.
* Disable profiling for a thread while it runs in the debugger support
code. This fixes potential deadlocks which could occur when a
profiling timer event occurred that would require the buffer to be
flushed while the thread was just sending something to the debugger or
waiting for a command. As it turns out, this is not sufficient either,
since we should never try to flush the buffer when the timer event
occurred in the kernel, since the thread might hold a lock that the
debugger thread could try to acquire. Will implement a more general
solution later.

BTextView classes:
* Declared the directly used BTextView helper classes as private BTextView
classes and changed all affected files.
* Realized that Tracker's BPoseView was (accidentally?) using what used to
be _BWidthBuffer_. It had declared it's own class with the same name and
same members/size in headers/private/tracker/TextViewSupport.h, but the
implementation was nowhere to be found. I can only explain this that
the BTextView implementation was then actually linked and used. But the big
problem was that it was used without locking (unlike in BTextView)! When
many Tracker windows opened during system startup or later and they happened
to each request characters not yet in the cache, I imagine things could have
gone bad and corrupted memory. Anyways, since I can see the usefulness of
the cache, BPoseView uses BTextView::WidthBuffer on purpose now. And I moved
the locking inside BTextView::WidthBuffer::StringWidth().
* Adjusted InterfaceDefs.cpp accordingly.
* TODO: Move subsequent classes into BTextView namespace as well, ie derived
classes that BTextView doesn't directly know about. All stuff in src/kits/
inteface/textview_support/
* Added preliminary and not yet implemented layout friendly BTextView
constructors.
* I will try to handle the insets imposed by BTextView::fTextRect a bit
differently when used inside the new layout management framework. For this,
I added BTextView::SetInsets() and GetInsets(). SetInsets() doesn't do
anything yet.
So far, everything seems to work still... ;-)

newly introduced callback feature, which notifies the debugger right
before returning from the interrupt.
* We didn't indicate that the profiling buffer was full and that the

unscheduled was incorrect.
* Introduced _kern_analyze_scheduling() syscall. It requires scheduler
kernel tracing to be enabled. It uses the tracing entries for a given
period of time to do a similar analysis the "scheduler" debugger
command does (i.e. number of runs, run time, latencies, preemption
times) for each thread. Additionally the analysis includes for each
thread how long the thread waited on each locking primitive in total.
* Added kernel tracing for the creation of semaphores and initialization
of condition variables, mutexes, and rw locks. The enabling macro is
SCHEDULING_ANALYSIS_TRACING. The only purpose is to provide
_kern_analyze_scheduling() with more info on the locking primitives
(the name in particular).

vector at the end of the file will be aligned to the given value.
* BFS uses an alignment of 512 bytes (should be block size of the
underlying device or BFS block size, whatever is less), which should
be fine, since file data are only stored in BFS blocks. This totally
avoids any partial operations at the I/O scheduler level, thus saving
disk operations. Not that I could measure any performance difference.
Theoretically it should help a lot though, particularly when dealing
with lots of small files, since we avoid using bounce buffers, which
are (a) limited in number and (b) require copying of the data.

referencing iframe registers. Their prefix is "$". E.g. "$eax" refers to
the eax register of the current iframe. The features cooperates with the
"in_context" command, i.e. "in_context 92 $eip = 0" will set the eip
register of thread 92 to 0 (thus sealing its fate ;-)).

due to alignment padding before.
* Reorganized merging of caches a bit. Renamed MergeStore() to Merge()
and moved some more functionality into it. The method also moves the
pages from source to consumer, now. This is necessary, since
VMAnonymousCache needs to consider both physical pages and swap pages
at the same time. Before we first moved the physical pages and the
swap pages later, which was broken for two reasons: (1) A swap page in
the consumer cache shadows a physical page of the source cache, which
we ignored. (2) A source cache's physical page that also had a swap
page would lose the latter in the process when moved to the consumer
cache, i.e. if the page was not marked modified, it could be stolen
and its data would be lost.
These changes improve the situation when building Haiku with 256 MB RAM
in that jam doesn't crash anymore, but in my test the system became
totally unusable after about an hour or 7000 targets (GUI froze). For
some reason it didn't manage to free pages anymore although swapping
heavily.

VMAnonymousCache (swap support) still has to be adjusted accordingly.
* write_page() doesn't need to map the page anymore as it can write the

- B_GET_VECTOR_ICON: retrieves the vector icon of a device, if any.
* get_device_icon(BBitmap*, ...) now supports other color spaces than B_CMAP8.
