is only really implemented for x86. For the other architectures
system_time() * 1000 is returned.

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.

- 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 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.

* 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

* VM{Kernel,User}AddressSpace manage the respective VMArea subclass now, and
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.

of the condition variable and synchronization subsystem of the freebsd compat
layer which will be committed next.

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.

BApplication creates it as done in BeOS. This requires manual

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.

* 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.

* Moved O_NOCACHE, and O_NOFOLLOW to the section with implemented modes.
* Added O_DIRECTORY.

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

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

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