f273b13ddb * Renamed xsi_ipc_init() to xsi_sem_init() as there will be a xsi_msg_init()
for message queue
* Removed unnecessary header Vector.h
* Removed HasSemaphoreSet method: since there will be an IPC table for each
  subsystem, if a key exist, it already has a semaphore set associated
  with it

4612433715 * Added parameter "size_t align" to file_map_translate(). If > 1, the
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.

1d059a02b9 Enabled swap file support by default. I successfully built Haiku with
256 MB RAM, 1.5 GB swap, and "jam -j2", so it basically seems to do its
job alright.

ec56835f51 Patch by David Powell:
* Implement color palette generation for the boot splash images in the
  generate_boot_screen build tool. Only 4-bit screen support is missing now.
* Adopted images.h with the new results from generate_boot_screen.

This should fix black boot screens for graphics cards that don't support
true color modes for the native resolution. I've tried to find the ticket,
#2177 almost looks like the one, but it looks more like the mode is out
of range if I understand the ticket right.

Thanks a lot, David, and sorry it took so very long to apply your patch!

740fe892ac Added a BColorQuantizer class to the "shared kit" based on a patch by David
Powel. The functionality was written by Jeff Prosise and Davide Pizzolato and
has been cleaned up and adopted to the Haiku coding style by David Powell and
myself. The class can perform a color quantization for generating the optimal
color index palette (with given maximum size) from a given RGBA image.

18f2a9c17d Added support for architecture specific debug variables, e.g. for
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 ;-)).

ed43619500 * vm_page: Swapped members usage_count and wired_count. We lost 4 bytes
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.

debug_{get,set}_debugged_thread(). By default the currently debugged
thread is the thread that dropped into the kernel debugger, but commands
like "in_context" can change it.

1cda5944ad Added object_cache_set_minimum_reserve() which sets the minimal number
of free objects an object cache should try to have ready. If the number
of free objects drops below the threshold, a new urgent priority thread
is asked to asynchronously resize the object cache (pretty similar to
the heap grower thread). Such a mechanism is necessary for code paths
that are supposed to free pages, but may need memory themselves (like
the swap support).

  given only the allocation for the specified heap are considered.

2a79a7686f * VMCache::Write(): Added "uint32 flags" argument which is supposed to
be passed on to the IORequest. Most relevantly physical pages can now
  be written directly by passing B_PHYSICAL_IO_REQUEST.
* Added VMCache::WriteAsync() which is supposed to write pages
  asynchronously. The base class version version falls back to the
  synchronous Write(). Only VMVnodeCache implements WriteAsync() ATM,
  VMAnonymousCache (swap support) still has to be adjusted accordingly.
* write_page() doesn't need to map the page anymore as it can write the
  physical page directly.
* Modified the page writer to write pages asynchronously. This shouldn't
  have any noticeable effect yet. It will though as soon as the I/O
  scheduler reorders I/O operations.

06ba3f0acb * Added two new ways to retrieve an icon from a device:
- B_GET_ICON_NAME: returns the name of an icon. This will then be read from
    a predefined location on disk (not yet implemented). This would also allow
    to add specifiers like "-boot", or "-fat|bfs|ntfs|...", and have special
    icons for those.
  - 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.
* Added get_device_icon(), BPartition::GetIcon(), and BVolume::GetIcon()
  variants that can also retrieve the icon data directly (like
  BNodeInfo::GetIcon()).
* Reenabled the previous BPartition::GetIcon(), based on a patch by
  Justin O'Dell - this fixes #1391.
* Tracker's MountMenu class now uses B_RGBA32 icons, instead of B_CMAP8.
* Added vector icon to scsi_disk, and scsi_cd. The former doesn't have any
  special removable icon, though.
* Header cleanup, added/updated license, whitespace cleanup.
* Marked deprecated/obsolete driver ioctls in Drivers.h.
* Removed OpenBeOS namespace in the headers I touched that still had them.

6ae7f6879f * Reworked the way sem_undo requests are processed by following
Ingo suggestions: instead of having one global sem_undo list,
  we now have two local list, one per semaphore set and one per team
  which is held in its xsi_sem_context structure, along with a mutex.
  A mutex has also been added to the semaphore set class in order to
  protect the local list, but also in order to (hopefully) improve
  concurrency.

our dma_restrictions structure (but we're using blocks instead of bytes,

* We might want to use blocks for the dma_restrictions structure as well in
  the future...

  segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.

afbd081a6f * TRACE macro no longer needs double parenthesis.
* The global BPathMonitor looper is now always used, no more optional looper
  and no more BApplication looper usage. This way we know how the looper behaves
  and PathHandler::Quit() can be synchronous. In the end, the bug I was
  observing was not caused by the previous asynchronous node monitor stopping,
  but this should be safer anyways. When BPathMonitor::StopWatching() returns,
  you have really stopped watching and not some time later.
* Introduced "FileEntry" which is an entry_ref plus node id. This is now used
  instead of the node_ref for the "watched files set". The whole point
  is to really be able to add the "path" field to the B_PATH_MONITOR message.
  Previously, the initial path that was passed to StartWatching() was added,
  regardless if the message was for an entry somewhere down the hierarchy when
  watching recursively. The downside of the new method is that it uses a lot
  more RAM per entry. Another option would be to store the node id of the parent
  directory and iterate the directory always when in need to construct the path.
* Watching a folder recursively now really adds all the existing subfolders
  as well as all the files if not watching for folders only. The tests for the
  old implementation only tested what happens when the watched folder was newly
  created and then subfolders were created. Those where already added by the
  code. Now it also adds the subfolders of folder that appear in a watched
  folder.
TODO: Remove folders and files recursively when they dissappear. More testing
for B_ENTRY_MOVED. Optimizations are possible when some information is
retrieved twice. I am also planning to add a way for the BPathMonitor user to
filter the automatically watched files/folders in B_WATCH_RECURSIVELY mode.

I grepped the entire Haiku tree for usage of BPathMonitor. Only net_server
and Mail were using it, but both in a way that is not affected by these
changes. Anyways, TextSearch works more reliable now, even for entries in
subfolders.

Feedback very welcome! :-)

f7c226f467 * StartWatching() now takes an optional BLooper pointer. This looper will
then be used for receiving node monitoring messages.
* Reenabled using be_app as default BLooper if the API user does not provide
  one. I think the problem that Stefano needed to work aroung in r23995 was
  actually caused by the incorrect locking (an never unlocking) of the looper
  before calling PathHandler::Quit().
->If I understand correctly, this code as supposed to work around the possible
  situation that the looper holding those PathHandlers may have already quit,
  leaving stale PathHandler pointers behind. But that case was not prevented
  by the old code anyways, since one would have had to access freed memory to
  even get the stale BLooper pointer. The real fix would be to store the
  BLooper pointer with each PathHandler so that the possible gone-ness of
  those loopers could be checked independent of accessing the PathHandler
  pointer. (The whole problem is that PathHandler adds itself to the BLooper
  and if the looper quits, it will free all its attached handlers.)
* Introduced a global fallback BLooper for the case that no BApplication is
  running, which resolves a TODO.

All this is yet untested, but should have a good chance of working.
(Famous last words...)

* Added vm_page_get_stats() which fills in the memory related part of
  the system_info structure. Used and cached pages are computed
  differently, now. The "available" (== not committed) memory is no
  longer used for the computation as it doesn't say anything about the
  actually used/free pages (with swap support enabled it is even
  less meaningful, since we first commit swap space when possible).
  We do also consider the memory used by the block cache as cached
  pages, now. All in all these changes should fix the memory statistics
  reported by get_system_info(), IOW bug #2574.

24593e2c79 * First baby steps in letting our drivers use the new I/O request/scheduler
architecture: for now, we do this on the lowest layer only, therefore all
  requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
  exporting a device on their own, and use an I/O scheduler with an appropriate
  DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
  you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
  of the previous read/write functions, moved preferred CCB size from those
  functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
  it); it's sometimes triggered by the code now, and I haven't yet looked into
  the issue -- doesn't seem to harm, at least.

  The stack size passed to _kern_spawn_thread() is now the actually usable
  size, and it is no longer possible to specify a size smaller than or
  equal to the guard pages size.
* vm_create_anonymous_area(): Precommit two pages maximum -- a stack with
  only one page usable size obviously doesn't need two pages.

7491000f20 Added functions file_cache_{disable,enable}(). They allow to disable
actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

59e13a3f06 Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
  interface, the ones for the solid cover simply pass through the existing
  methods, so only one subpixel blending function is left which does the actual
  work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
  implements subpixel anti-aliasing for any generic AGG vector pipelines. It
  is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
  rotated, sheared or big enough fonts) depending on the global subpixel
  setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
  FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
  to InterfaceDefs.cpp where other such functions live. They are not related
  to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
  them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

7f12cc54a7 * It is now supported that I/O operations and requests are only handled
partially (e.g. due to hitting the end of file). The respective
  classes have grown new methods and attributes to deal with that. The
  "finished" callbacks have got additional parameters to indicate
  whether the transfer was only partial and how much has been
  transferred. Other callbacks and functions have a size_t* in/out
  parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
  of the underlying FS's {read,write}_pages() hooks (those should be
  unused now). Furthermore they've got an additional "flags" parameter,
  which is passed to IORequest::Init(), i.e. it allows to specify that
  the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
  pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
  pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
  do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
  driver I/O requests are passed all the way from the VFS/VM to the
  driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
  methods.
* Disabled some debug output by default. Added new optional debug
  output.

* Added _kern_*() syscall prototypes to syscalls.h.
* Added a TODO in xsi_sem.cpp and xsi_semaphore.h about moving union semun to
  a shared header.
* Made the team::xsi_sem_undo_requests int32 - due to padding, it would have
  needed 4 bytes anyway; please always use specific types over int/short/long.
* xsi_sem_undo() now checks if it needs to do anything - the calls in team.cpp
  no longer needs to do this.

ec598fe493 * Added FS interface hooks io() and cancel_io(). The former is supposed
to provide asynchrounous (or only synchronous, if asynchronous is not
  supported) I/O request support. It will eventually replace
  {read,write}_pages(). None of the FS implementations implement them
  yet.
* Implemented some support functions for request-based I/O. File system
  implementations can use do_fd_io() which passes an I/O request to the
  layer responsible for a given FD, and do_iterative_fd_io(), which
  translates a request for a file to subrequests for the underlying
  device and passes them on. Both fall back to synchrounous processing
  when the io() hook is not supported.
  Furthermore added vfs_synchronous_io() which should be handy for the
  devfs to perform io_requests synchronously for devices that don't
  support the io() hook.

8881176ff3 A module that hooks into the debugger to provide it with a demangle() so at least when using C++ in the kernel stack crawls are meaningful.
It does its job by using part of libsupc++, with fake malloc and friends to make sure it won't double fault.
Works here, but cp-demangle must be extracted by hand from the lib, can't get the rule to work as I want, Ingo ?
Maybe using it directly without malloc hack would be ok with 16KB buffer, but I'm not sure of that.

5c99d63970 Merged branch haiku/branches/developer/bonefish/vm into trunk. This
introduces the following relevant changes:
* VMCache:
  - Renamed vm_cache to VMCache, merged it with vm_store and made it a
    C++ class with virtual methods (replacing the store operations).
    Turned the different store implementations into subclasses.
  - Introduced MergeStore() callback, changed semantics of Commit().
  - Changed locking and referencing semantics. A reference can only be
    acquired/released with the cache locked. An unreferenced cache is
    deleted and a mergeable cache merged when it is unlocked. This
    removes the "busy" state of a cache and simplifies the page fault
    code.
* Added VMAnonymousCache, which will implement swap support (work by
  Zhao Shuai). It is not integrated and used yet, though.
* Enabled the mutex/recursive lock holder asserts.
* Fixed DoublyLinkedList::Swap().
* Generalized the low memory handler to a low resource handler. And made
  semaphores and reserved memory handled resources. Made
  vm_try_resource_memory() optionally wait (with timeout), and used that
  feature to reserve memory for areas.

69dddbdea1 Initial work towards supporting IO APICs. This cannot work for PCI interrupts
though until we use ACPI for proper PCI IRQ routing through the IO APIC.
Therefore the IO APIC code path is not yet enabled and the IO APIC isn't used.
ISA interrupts would work though, as would PCI interrupts if you'd hardcode
them for your specific configuration.
Note that this change also modifies some parts in the bootloader and in the PIC
setup to make local APICs available even on non-SMP systems. This causes APIC
timers to be used instead the normal PIT if it is available (also on non-SMP
configurations).
Also fixes some general errors in SMP and PIC code as well as some code cleanup.

aebcc506e2 Corrected by previous assumption, since gethostbyname() has nothing to do with
struct sockaddr_in - the real culprits were BNetAddress::GetAddr(sockaddr_in&)
and BNetAddress::SetTo(const sockaddr_in&):
* moved check_r5_compatibility() into r5_compatibility.h to make that function
  available to BNetAddress, too
* adjusted sockaddr_in-handling methods of BNetAddress to deal with R5-addresses
  if in compatibility mode
* removed is_r5_sockaddr() again, since it is no longer needed

With this less hacky solution, Beam, NetPositive, NetworkTime and Vision still work. So, there's hope that the R5 compatibility layer is now complete.

b1f4df4a62 Implement heap classes that each have their own range of allocation sizes they
serve, bin sizes and page size. This minimizes the amount of "large"
allocations made in heaps that don't have a bin for the allocation size
(combining multiple pages). This is desirable as such large allocations
are generally pretty inefficient, and also because it separates larger from
smaller allocations better, making the chance of a heap becoming empty higher.
For now there are three heap classes "small", "large" and "huge", with a
predefined set of bin sizes for each. This might need some finetuning later on.
Reduce the grow size to 4MB though as the allocations should now be spread
across heap classes which each grow on their own.

8531599a27 * KDiskDeviceManager::RescanDiskSystems() now also rescans all partitions with
the newly found disk systems.
* _ScanPartition() now allows to restrict the disk systems to a predefined set.
* _ScanPartition() now even scans partitions that already have a disk system
  assigned; if a better one is found, the existing one is replaced. It will
  ignore mounted or partitions with children, though.
* KPartition now also stores the priority of the disk system assigned to it.

e1b630c55d * Replaced the global cache pages hash table by an IteratableSplayTree
per cache.
* Changed the strategy vm_cache_acquire_page_cache_ref() uses to ensure
  that the cache isn't deleted while trying to get a reference. Instead
  of the global cache pages hash table lock, it holds the global cache
  list lock now. We acquire + release this lock in delete_cache() after
  removing all pages and just before deleting the object.
* Some small optimizations using the property that the cache's pages are
  ordered, now (vm_cache_resize(), vm_page_write_modified_page_range(),
  vm_page_schedule_write_page_range()).
* Replaced some code counting a cache's pages by simply using
  vm_cache::page_count.

2965c99fea * Changed the _kern_exec() and _kern_load_image() syscalls. They expect
a flattened argument/environment buffer now. This simplifies the work
  for the kernel a bit, since it can just copy the buffer and check
  whether it looks OK instead of messing around with individual strings.
  The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
  When more arguments are passed, we fail with a proper error code
  (instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
  name, which is not correct.

df7096a4aa * Added malloc_nogrow() function that does allocation without triggering or
waiting for a heap grow.
* Use that nogrow version in the VM code to avoid a deadlock with the address
  space lock when a grow operation would try to create an area while a malloc
  happened from such a function in the VM.
* When waiting for a grow to happen, notify the waiting thread from the grower
  also if it failed to allocate a new heap. Otherwise a thread would just sit
  there and wait until another thread requested growing too and that one
  succeeded (or just forever in the worst case).
* Make the dedicated grow heap growable too. If the current grow heaps run low
  on memory it will instruct the grower to allocate a new grow heap. This
  reduces the likelyhood of running out of memory with no way to grow to a
  minimum. As the growing is done asynchronously it is still possible to
  happen, but it is highly unlikely as the grow heap is solely used to
  allocate memory in the process of creating new heap areas and it will even
  try using normal public memory if the dedicated memory has run out.
* Reduced the dedicated grow heap from 2 to 1MB. As it can now grow itself, it
  doesn't need to last so long.
* Extract heap creation into it's own function that does area creation and heap
  attach and use this function for growing normal and grow heaps.

  (currently only 'us' and 'sg' are available though).
* Provide a third keymap that is used when the alt modifier is used (the swiss
  german keymap is pretty useless without alt as all the useful keys like
  backslash and curly braces use alt).

Our KDL is so powerful and nice to use, the only thing that bothered me was
that I always had to think about where some of the special keys are located in
the US keymap. So this simple compile-time keymap switching provided to be
helpful for me and might be for others too. Keymaps for other layouts obviously
have to be written before this becomes really useful.

B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
  structure (thus breaking BeOS binary compatibility), containing a
  counter which is incremented whenever a thread has to wait for the
  spinlock.
* Added macros for spinlock initialization and access and changed
  code using spinlocks accordingly. This breaks compilation for BeOS --
  the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
  the team spinlocks.

73aa393d73 * Introduced pipes in the kernel debugger. The syntax is similar to
pipes in the shell, though the semantics is a little different: The
  second command is invoked whenever the first command has written a
  complete line. The line is passed as last argument to the second
  command. The new command flag B_KDEBUG_PIPE_FINAL_RERUN causes the
  second command to be invoked again (with NULL argument) after the
  first command is done.
* Added kprintf_unfiltered() and kputs_unfiltered() which bypass the
  pipe mechanism and directly print to the bluescreen/serial output.
* Moved most commands from debug.cpp to the new
  debug_builtin_commands.cpp.
* B_KDEBUG_DONT_PARSE_ARGUMENTS commands don't get an argument anymore,
  if it would consist of white space only.
* Added new debugger command return value B_KDEBUG_ERROR, which
  indicates that executing the command failed. This return code will
  abort a complete pipe.
* Since debugger commands can nest (i.e. one command can invoke another
  one) the setjmp()/longjmp() mechanism to restore the stack after a
  page fault in a command needs more than one jump buffer.
* Added abort_debugger_command(), which longjmp()s out of the currently
  executed command. This will also abort the current pipe.
* When pagination is enabled pressing "a" will abort the running command
  (as opposed to "q" which only disables the blue screen output, but
  lets the command continue).
* Added debugger commands:
  - "grep" which can be used to filter output by pattern. Removed the
    "filter" command and the underlying mechanism that did that before.
  - "head" which prints only the first lines of output of another
    command.
  - "wc" counts lines, words, and characters of another command's
    output.

590c0d667c Darn... should have been part of my last commit:
Export the Read/Write locking strategies from the BPrivate namespace. Fixes
Icon-O-Matic build (RWLocker).

9101535322 Added new kernel thread "undertaker" which gets rid of dead thread
remains. This replaces the previous mechanism of switching the thread to
a dedicated death stack. We might consider moving more cleanup work to
the undertaker, but that seems a little more involved.

R/W locks.

1c18a5df87 Replaced R/W lock implementation. Should have a little less overhead
than a semaphore, and can already be used in the early boot process.

b0f5179aa5 * Changed recursive_lock to use a mutex instead of a semaphore.
* Adjusted code using recursive locks respectively. The initialization
  cannot fail anymore, and it is possible to use recursive locks in the
  early boot process (even uninitialized, if in BSS), which simplifies
  things a little.

9f16184577 Patch by Jan Klötzke with minor changes by myself:
* Use vm86 mode to call the VESA BIOS to do the actual mode switching by
  providing an ioctl in the vesa driver.
* Fix vm86.h.

368167ede8 * Integration of the new driver architecture.
* Moved devfs from fs/ to device_manager/, and separated the legacy driver
  support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
  - legacy SATA and ISA IDE support is disabled, the drivers haven't been
    ported yet.
  - The not yet used ATA bus manager hasn't been ported yet, either.
  - AHCI changes have not been tested.
  - the listdev command has been removed from the build (as it currently
    doesn't work anymore).
  - device manager generated IDs currently are not freed anymore when a device
    node is removed.
  - generic drivers can't yet use the new driver architecture.
  - simple busses that do not support device types won't work yet.
  - legacy driver publishing/unpublishing (ie. what USB needs) has not been
    tested, and may be broken.

0f448d21e5 * Added vm_page_write_modified_page_range(), which is similar to
vm_page_write_modified_pages(), save that it only writes pages in the
  given range.
* Added vm_page_schedule_write_page_range() which schedules all modified
  pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.
