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.

of the condition variable and synchronization subsystem of the freebsd compat
layer which will be committed next.
* Also there was a discussion about adding these functions on the commit
mailing list. The mail in http://www.freelists.org/post/haiku-commits/r34395-in-haikutrunksrclibscompatfreebsd-network-compatsys,3
is a good sum up of it (need to scroll somewhat down, though).

* "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.

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

and doesn't have to find it every time), and create_desktop_connection() that
is now used from BApplication::_ConnectToServer() as well as the DesktopLink.
* Move PortLink::SetTo() into base class ServerLink.
* Eliminated duplicated member fReplyPort in DesktopLink.
* Cleanup.

* be_clipboard is no longer created at libbe initialization time. The
BApplication creates it as done in BeOS. This requires manual
initialization in the registrar to avoid a deadlock on shutdown.

changes the semantics slightly: Previously after a failed initialization
another invocation of InitializeDefault() could theoretically initialize the
converter. Since the only error conditions are out of memory and broken app
server connection, this shouldn't really matter, though.

but wouldn't work when running it on Haiku anyway. At any rate, it was
relatively expensive (uname()) and used already in the libbe
initialization.
* Got rid of the non-Haiku support of main_thread_for().

subdirectory locks/).
* runtime_loader no longer includes the rw_lock, allowing removal of the TLS
dependency again.

Bosii is a transcription of 802.11. It is a work-in-progress title to
point out parts of the wlan stack which are still in an experimental state.
For example the control codes within bosii_driver.h are moving targets.

as a mutex, but allocates its semaphore lazily. This comes at the cost of an
additional atomic_add() when the semaphore has actually to be acquired, but
saves the semaphore creation completely in single-threaded programs and in
any program when there's no lock contention.

- Request channel pointer also for non l2cap signal frames
- Add locks for packet queues

resource manager.
* Could be drastically improved, though, by taking the fragmentation into
account.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34309 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented renameat(), faccessat(), fchownat(), fchmodat(), and mkfifoat().
* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
effective and real user/group IDs, though.
* Removed B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT, as we now support everything
(more or less). This also closes ticket #4928.

(O_MOUNT, O_EXLOCK, and O_SHLOCK). I only left the non-standard O_TEMPORARY
for the time being (as it shouldn't fool anyone).
* Fixed libutil that already used O_EXLOCK, even though it did not do anything.
* Moved O_NOCACHE, and O_NOFOLLOW to the section with implemented modes.
* Added O_DIRECTORY.

regards to locking and seeking.
* Furthermore, we now not only cache 4 chunks, but chunk up to a certain
memory size (MediaExtractor uses 1 MB for now).
* Since I still have occasional hickups, it looks like this wasn't the main
cause for our audio problems. Still, this will reduce drive access
considerably during play.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34243 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added FSSH_[S]SIZE_MAX to headers/private/fs_shell/fssh_types.h.
* Fixed various 64 bit compiler warnings. Nothing too serious, though.

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,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

checking the physical frame buffer location.
* This allows us to map the whole frame buffer at once, which means there is no
need anymore to remap the memory on mode change.
* Also, this will ease the burden of the MTRRs, as the memory size will be
properly aligned.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34206 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
