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.

- 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
* Cleaned up private method names as much as possible (it's probably not a good
idea to rename BStatable::set_stat() for compatibility reasons).
* Cleaned up sources.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34690 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.

header. This shall ensure uniqueness of the ioctls.
* Added a special SIOCEND define to Haiku's sockio.h, so that drivers can define
private ioctls as can be seen in src/add-ons/kernel/drivers/network/wlan/atheros/dev/ath/if_athioctl.h.
* Modified ioccom.h of the FreeBSD compat layer, to make use of the special
SIOCEND define.

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().

* 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.

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.

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.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34521 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added operator== and !=
* Added check for list != this in operator=
* Added HasItem() and IndexOf() versions that take const void*, duplicating
the code, since I didn't want to introduce another function call in these
potentially time critical methods.

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.

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

VMAddressSpace has grown factory methods {Create,Delete}Area.

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. :-)

* 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.

layer which will be committed next.

mailing list. The mail in http://www.freelists.org/post/haiku-commits/r34395-in-haikutrunksrclibscompatfreebsd-network-compatsys,3

* "Classified" VMAddressSpace, i.e. turned the vm_address_space_*() functions
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.

* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between

That's just leading to problems.
* Fixed various 64 bit warnings when building libbe_build.so. One of the more
serious issues, that might bite us, is that 64 bit Linux defines dev_t to
unsigned long, while Haiku code assumes that it is signed and 32 bit. We'll
see...

and types.h. The idea is to provide a basic architecture/compiler
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,

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.

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).

(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.

* its own heap allocator instead of cbuf - this makes cbuf superfluous, and I
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.
* Needed to move the port initialization to a later point, as swappable memory
wasn't usable that early.
* All ports test are still passing, hopefully I didn't mess anything up :-)

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

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.
* Pulled out PageWriteTransfer methods for better readability.

- 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.

also providing Lock() and Unlock(). Applied public header style.

Remove the 4 cores limit at boot, and fix the allocator to handle 8 cores.
There are still performance problems, but this allows booting with 8 cores.
WARNING: since this changes x86 platform kernel args, you really don't want to update haiku_loader and kernel_x86 separately!

aren't routed correctly over the 8259, it seems.
- Removed passing the hpet_regs around, since there's a static variable.
- Added lots of debug dprintfs.
- Fixed setting the timer interrupt to edge
- Timer is initialized once.
- Use the timer 0 instead of 2.
- Renamed register definitions to be more readable
- Use 64 bits registers and unions where applicable.
- Other things I don't remember

Also shortened some defines using "TN" instead of "TIMER". It's also
the same scheme used in the specs
