b19e758b80 * The Keymap::IsDeadKey() of the Keymap preferences which was the main source
of BKeymap was not compatible with IsDeadKey() of the other Keymap
  incarnations.
* Now, I've renamed IsDeadKey() to DeadKey(), and introduced a new
  ActiveDeadKey() method that works like the other former IsDeadKey().
* This fixes the dead key problems my earlier BKeymap work introduced.

efeca209a1 Made VMCache::Resize() virtual and let VMAnonymousCache override it to free
swap space when the cache shrinks. Currently the implementation stil leaks
swap space of busy pages.

b44c25de42 * Factored out a single base class out of the three Keymap implementations we
had in our tree.
* Adapted Keymap, <input>keyboard, and consoled to use it - the additional
  functionality is implemented via a subclass in the first two cases.
* "keymap" will come next.

f71274580b * Private libroot locking primitives:
- Reimplemented mutex to use the _kern_mutex*() syscalls.
  - The initializer functions cannot fail anymore -- changed their return type
    to void.
  - Changed the initializer function semantics to not copy the name by default
    anymore (as in the kernel). Also added *_etc() versions of them that take an
    additional flags.
  - Added static initializer macros.
  - Made the mutex (and thus recursive_lock) lock functions non-interruptable.
  - Got rid of the "lazy" version. They are no longer needed, since the
    initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
  locking primitives to the new semantics.
* pthreads mutexes and condition variables:
  - Reimplemented using the _kern_mutex*() syscalls.
  - Consistently use POSIX error codes.
  - Fixed some not quite POSIX compliant behavior.

186058c517 Some corrections and cleanup to ACPI Embedded controller:
* Exposed ACPI API needed by Embedded Controller
	This will be removed again if moved inside the bus manager.
	It also duplicates ACPI's own headers so it might go out of sync atm.
 * Added mutex to controller and fixed the mixup between acpi_status needed in int handlers and Haiku status.
 * Major code cleanup
	Not for headers as they are mostly redundant if we move the controller.
	Variable names still needs some cleanup

This makes the ACPI errors from the controller understandable. I get AE_NO_HARDWARE_RESPONSE now.

can safely be used.
* Since using the I/O APIC is disabled by default, I've removed the "return"
  that prevented its use when enabled. Let's see if it already does anything.

a608485f26 * Added new team flag B_TEAM_DEBUG_PREVENT_EXIT that prevents teams from exiting
via exit() (the calling thread will drop into the debugger instead).
* The DebugServer now uses this flag by default.
* Added TODO comment: the default debugger should already be able to set a flag
  like this in order to close a race condition between dropping a thread into
  the debugger and setting the flag.
* Cleaned up the debug_server sources a bit.

897ca37d52 * Introduced a new debugger access to the keyboard drivers, and implemented that
in the PS/2 driver for now. The basic idea is to allow everyone to open the
  device, but only allow one key reader (as usual). However, once someone
  registers itself as a debugger, the original reader is blocked, and the
  debugger can read the key presses instead.
* Renamed ps2_keyboard.c to .cpp.

c3676b54bf * Added vm_debug_copy_page_memory() which copies memory from a potentially not
mapped page.
* debug_{mem,strl}cpy():
  - Added "team" parameter for specifying the address space the address are
    to be interpreted in.
  - When the standard memcpy() (with fault handler) fails, fall back to
    vm_debug_copy_page_memory().
* Added debug_is_debugged_team(): Predicate returning true, if the supplied
  team_id refers to the same team debug_get_debugged_thread() belongs to.
* Added DebuggedThreadSetter class for scope-based debug_set_debugged_thread().
  Made use of it in several debugger functions.
* print_demangled_call() (x86): Fixed unsafe memory access.

Allows KDL stack traces to work correctly again, even if the page daemon has
already unmapped the concerned pages.

33fbe25496 * Add code to allocate and free interrupt vectors for message signaled
interrupts (MSI).
* Add the remaining IDT entries and redirection functions in the interrupt code.
* Make the PIC end_of_interrupt() return a result to indicate whether the vector
  was handled by this PIC. If it isn't we now issue a apic_end_of_interrupt()
  in the assumption of apic local interrupt, MSI or IPI. This also removes
  the need for the gUsingIOAPIC global and doing manual apic_end_of_interrupt()
  calls in the SMP and timer code.

b289aaf66b * A BBuffer does not know where it came from, so
BBufferConsumer::BufferReceived() cannot know whom to send the "buffer is
  late" notification (unless we only have a single input). To solve this, the
  media_header now contains extra fields that can be used to create a
  media_source object.
* Unfortunately, BBufferProducer::SendBuffer() cannot know the output either in
  case there is more than one. Hence, I deprecated the existing SendBuffer()
  call and moved it into "private" - IOW old sources using it won't compile
  anymore under Haiku.
* I introduced a new SendBuffer() variant that also gets the media_source as
  argument.
* Updated all sources (that are part of the image) to use the new variant.
* Removed some purposely commented out code in the audio mixer.
* Implemented late buffer notification, as well as late buffer handling in the
  audio mixer; this is a bit of work in progress, so the debug output is left
  in there.
* Some cleanup.

f7b0c08cae This modifies the Postscript printer to be able to insert a pipe in between the Postscript generation
and the transport addon. The actual command use as pipe is retrieved from the PPD that can be selected
at printer creation time.

Currently PPD selection is not shown (as the PPD directory is not available) and therefore the pipe
will not be inserted.

This still needs a bit of TLC, so hope to commit the last changes to fully support this later this week.

813d4cbe94 * Moved created subdirectory src/system/kernel/lock.cpp to new subdirectory
locks.
* Added syscalls for a new kind of mutex. A mutex consists only of an int32 and
  doesn't require any kernel resources. So it's initialization cannot fail
  (it consists only of setting the mutex value to 0). An uncontended lock or
  unlock operation can basically consist of an atomic_*() in userland. The
  syscalls (when the mutex is contended) are a bit more expensive than semaphore
  operations, though.

550376ffb8 * vm_delete_areas(): Changed return type to void (was status_t and not used).
* _user_map_file(), _user_unmap_memory(): Verify that the address (if given) is
  page aligned.
* Reworked memory locking (wiring):
  - VMArea does now have a list of wired memory ranges and supports waiting for
    a range to be removed.
  - vm_soft_fault():
    - Added "wirePage" parameter that, if given, makes the function wire the
      page and return it.
    - Added "wiredRange" parameter (for calls from lock_memory_etc()) and made
      sure we never unmap wired pages. This could e.g. happen when a page from a
      lower cache was read-mapped and a write fault occurred. Now in such a
      situation the function waits for the page to be unwired and restarts.
  - All functions that manipulate areas in a way that could affect wired ranges
    do now either require the caller to make sure there are no wired ranges in
    the way or do that themselves. Added a few wait_if_*_is_wired() helper
    functions for that purpose.
  - lock_memory_etc():
    - Does now also work correctly when the range spans more than one area.
    - Adds VMAreaWiredRanges to the affected VMAreas and retains an address
      space reference (so that the address space won't be deleted as long as a
      wired range exists).
    - Resolved TODO: The area's caches are now locked when
      increment_page_wired_count() is called.
    - Resolved TODO: The race condition due to missing locking after looking up
      the page mapping is now prevented. We hold the cache locks (in case the
      page is already mapped) and the new vm_soft_fault() parameter allows us
      to get the page wired.
  - unlock_memory_etc(): Changes symmetrical to those in lock_memory_etc() and
    resolved all TODOs.

feddedab0c x86:
Added fields for temporary storage of the debug registers dr6 and dr7 to the
arch_cpu_info structure. The actual registers are stored at the beginning of
x86_exit_user_debug_at_kernel_entry() and read in
x86_handle_debug_exception().
The problem was that x86_exit_user_debug_at_kernel_entry() itself overwrote
dr7 and, if kernel breakpoints were enabled, dr6 could be overwritten anytime
after. So x86_handle_debug_exception() would find incorrect values in the
registers (definitely in dr7) and thus interpret the detected debug condition
incorrectly. Usually watchpoints were recognized as breakpoints.

76ab3f88df Basically, this changeset implements BShape::ArcTo(). In more detail:
* 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

  - 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.

    Currently saving the syslog to FAT32 volumes is supported.

28a2172c3f kernel:
* 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.

e59dc33e21 * Added BCursorID enumeration in App Kit's Cursor.h and new constructor which
takes such an id.
 * 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.

a070cf5306 * Indentation update in DateTime.h
* 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.

d40a935560 Boot loader (x86 mmu.cpp):
* 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.

8b3d3d8a15 Correctly handle cases when a thread single-steps into the kernel as it can
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.

ff59ce680d * The low resource handler now empties the cache depot's magazines; before,
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.

dac21d8bfe * map_physical_memory() does now always set a memory type. If none is given (it
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.

081ff2db28 * Add heap_debug_set_memory_reuse() which allows to disable memory reuse,
keeping all returned heap memory in the 0xdeadbeef state (including the
  first sizeof(void *) bytes otherwise for the free list). While wasting a lot
  of memory it allows you to rely on 0xdeadbeef being always present as no
  future allocation will reuse the freed memory block.
* Also added heap_debug_malloc_with_guard_page() which is intended to allocate
  a memory block so it is aligned that the start of invalid memory past the
  allocation is in an unmapped guard page. However the kernel backend that would
  guarantee this is not yet implemented, so right now this works only by chance
  if no other area happens to be allocated exactly past the created one. With a
  very specifc suspicion you can put that one allocation you get to good use
  though. It causes a crash when accessing memory past the allocation size so
  you actually get a backtrace from where the access happened instead of only
  after freeing/wall checking.

40bb94819e * Removed useless return parameter from vm_remove_all_page_mappings().
* 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.

5bc9fb9d24 * Replace the truncate_string() helper function with a new, simplified version.
* 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.

72382fa629 * Removed the page state PAGE_STATE_BUSY and instead introduced a vm_page::busy
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.

  (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.

cff6e9e406 * The system now holds back a small reserve of committable memory and pages. The
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.

b4e5e49823 MemoryManager:
* 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.

8d1316fd23 Replaced CACHE_DONT_SLEEP by two new flags CACHE_DONT_WAIT_FOR_MEMORY and
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.

86c794e5c1 slab allocator:
* 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.

Side effect : all languages in Locale window are now displayed in the current locale. It makes more sense as otherwise the list would be unsortable. However it can get annoying if you mistakenly set a strange language as default.

453a2bdd18 Replaced the locking strategy (formerly a recursive lock for the depot and
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.

  team. The semaphore was released by the undertaker.

6379e53e2d vm_page no longer points directly to its containing cache, but rather to a
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

* 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.

f082f7f019 * Added vm_page::accessed flag. Works analogously to vm_page::modified.
* 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

* Renamed vm_translation_map to VMTranslationMap and made it a proper C++

* Added class GenericVMPhysicalPageMapper implementing VMPhysicalPageMapper

* Adjusted the x86 and the PPC specifics accordingly (untested for the

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

14429e896e Reverted the part of r31520 that made devfs_unpublish_partition() take a raw
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.

8ab820f076 VMAddressSpace::Put() is too hot to always write lock the address spaces
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%.

3cd2094396 * Added new debug feature (DEBUG_PAGE_ACCESS) to detect invalid concurrent
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.

3a57be2aea * Indentation and naming cleanup in the header
* Small coding style cleanups in the .cpp
 * When reading raw chunks, keep fCurrentFrame updated anyway
 * When decoding frames and chunks, don't change the meaning of fCurrentTime,
   it's supposed to be the start time of the next chunk/frame, same as
   CurrentFrame(), not the time of the frame/chunk we just decoded/read.
   BMediaTrack::CurrentFrame() is actually documented like this in the BeBook,
   but CurrentTime() is not. However, when seeking to a specific time, it is
   understood that this is the time of the next frame/chunk. If we decode/read
   it and set fCurrentTime to the start_time as specified in the media_header,
   it would actually not change for the first frame/chunk after seeking.
   To be able to know the duration of chunks, fWriterFormat had to be changed
   to just fFormat and is now used for decoding as well.
* Simplified handling of media_header in some methods, saves one assignment.

These changes are not so well tested, yet.

2ea2527fe4 R/W lock implementation:
* 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.

eb8dc1ebfb * Removed DEBUG_PAGE_CACHE_TRANSITIONS debugging.
* 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.

0338371f26 * All scheduler implementations:
- enqueue_in_run_queue() no longer returns whether rescheduling is supposed

  - 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.

* 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%.

3533b6597d * Reintroduced the SMP_MSG_RESCHEDULE_IF_IDLE ICI message. This time
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.

  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

* 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.

522c2f19d4 * Added a simple mechanism to wait for events to VMCache. WaitForPageEvents()
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.

40cd019ea0 * Renamed VMAddressSpace::ResizeArea{Head,Tail}() to ShrinkArea{Head,Tail}()
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.

a54549a8cd * AVLTree:
- 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.

9dec231042 Sorry for this large commit in advance; it's not really possible to divide this
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
