* Got rid of <dirent_private.h> -- the __DIR structure is private to dirent.c,
now. The attribute directory, index directory, and query functions use the
the public POSIX API, so does the kernel module code. Those components were
not initializing the structure correctly anymore since the introduction of
telldir()/seekdir().

workspace activation message was asynchronous, whether or not the
BWindowScreen stopped drawing in time was pure luck (this also caused crashes
with the VESA driver, as that one unmaps its frame buffer during mode switch).
Introduced a new AS_DIRECT_SCREEN_LOCK protocol for this.
* In the long term, we should let BWindowScreen use the same mechanism as
BDirectWindows, though.
* Removed superfluous locking in BDirectWindow::_InitData().

B_CURRENT_WORKSPACE_INDEX constant.

* scheduler_enqueue_in_runqueue() now allows the scheduler to return a hint as to whether a reschedule is desirable or not. This is used in a few other places in order to relegate scheduling decisions entirely to the scheduler rather than the priority hacks previously used. There are probably other places in the kernel that could now make use of that information to more intelligently call reschedule() though.
* Switch over the default scheduler to scheduler_affine().

make it work, one would need to use versioning for all libbe symbols. This is
worth an 8k price per file that links against libbe.so, so I didn't want to
commit this as is. An alternative to this solution would be to write a
separate application that is responsible for the app_server's window. Comments
welcome.
* Removed BeOS compatbility of the libbe_test stuff.
* Renamed the libbe_test targets from *haiku* to *test*, ie. libbe_haiku.so is
now called libbe_test.so, haiku_registrar is now test_registrar, etc.
* This also removes BeOS compatibility from tracker/FSUtils.cpp (all BeOS
compatibility should be removed, but I don't want to make Alexandre more work
in his branch, and it's not urgent at all).
* Replaced the former "run" scripts for the test environment with a single
run script (see updated NOTES file).
* Removed the libbe_test target from some applications - this was only to help
developing them under BeOS, and is thus no longer necessary.

* Keep track of the currently running threads.
* Make use of that info to decide if a thread that becomes ready should preempt
the running thread.
* If we should preempt we send the target CPU a reschedule message.
* This preemption strategy makes keeping track of idle CPUs by means of a bitmap
superflous and it is therefore removed.
* Right now only other CPUs are preempted though, not the current one.
* Add missing initialization of the quantum tracking code.
* Do not extend the quantum of the idle thread based quantum tracking as we want
it to not run longer than necessary. Once the preemption works completely
adding a quantum timer for the idle thread will become unnecessary though.
* Fix thread stealing code, it did missed the last thread in the run queue.
* When stealing, try to steal the highest priority thread that is currently
waiting by taking priorities into account when finding the target run queue.
* Simplify stealing code a bit as well.
* Minor cleanups.

device is not compatible, after all.
* No longer accept color changes if the mode is not an 8 bit one. I think that
BWindowScreen does that after changing the mode, so that is messes up the
colors, at least that's the theory, will test on real iron now.
* Use VGA as a fallback if setting the palette via VBE failed. This brings back
the colors for ParticlesII in Qemu (but not in VirtualBox, which seems to be
completely broken in this regard).

Start of framebuffer initialization for the Verdex board.
For now it points to the data section as framebuffer for testing and shows an RGB pattern.

* The vesa driver no longer uses VGA programming if the chip does not support
VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
the new vesa_set_indexed_colors() that is now used for palette programming.
This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
right now, the colors are garbled after a workspace switch. Stefano, are you
looking into that already?

- don't clobber the parameter regs in the entry point,
- fix entry point address for netbsd loader emulation,
- added a gUImage global to point to the uimage blob with the tgz,
- added tgz info to platform stage2 args,
- add simple uimage support, just dumps the header and gets the nth blob in the image, (seems we have a bug in the math code, some infos don't print),
- made devices.cpp use them to publish the MemoryDisk,
- add an haiku_loader_nbsd.ub target which puts both the loader and kernel_arm for now (need to replace with the tgz).

* Fleshed out the Encoder API to support parameter setters/getters and returning
a BView for configuration. (Not yet sure if this is a good idea.)
BMediaTrack:
* Implemented all but one of the unimplemented methods in BMediaTrack. It should
be working as far as that class is concerned, unless I missed some of the
vision. ReplaceFrames() remains a stub, added a comment on why it probably
stays that way.
* Release the Encoder reference in the destructor.
FFmpeg plugin:
* Refactoring to delay opening the AVCodec until encoding the first chunk,
so that we can still adjust parameters.
* Support adjusting parameters via [Set|Get]EncodeParameters(). Currently,
only quality is supported, added TODOs about supporting the bit_rate setup
versus the automatically calculated bit_rate.
* Extended EncoderDescription by a bit_rate scale. The Encoder calculates the
raw bitrate needed by the current media format, and then divides that
number by the specific codec's bit_rate_scale, while taking into account the
desired quality. This seems to work very well already (tested with MPEG4),
although a lot more parameters could be specified for libavcodec, depending
on the desired quality.
* Enabled the ogg muxer in libavformat, although it is currently still disabled
in MuxerTable.cpp, because it rejects unknown codecs. Added TODO to this
effect.

* The BView API can probably be regarded as good enough; the implementation
might need to be improved over time (also, some things as archivability
aren't fully implemented yet). The ToolTip.h header should get public once
finalized.
* Added new B_MOUSE_IDLE message that is sent to a BView after a certain
time has passed (BToolTipManager::ShowDelay()).
* Added small test app (ToolTipTest) that shows what is already working.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32078 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added some multiboot support code:
- dump some of the passed info,
- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

allow for more parallelism. Also introduce seperate locks for the bins and
for page allocation. This greatly reduces lock contention and reduces the
duration the locks are held due to them overall protecting less code. Now only
allocations of the same size hitting the same allocator or allocating larger
chunks of memory should block. Previously, basically any allocation and also
free would be mutually exclusive, making it scale pretty badely.
* Added memalign_nogrow(). As it uses heap_memalign() anyway, there's no real
reason not to allow for an alignment.
* Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32074 a95241bf-73f2-0310-859d-f6bbb57e9c96
ROUNDUP to use '*' and '/' -- the compiler will optimize that for powers of
two anyway and this implementation works for other numbers as well.
* The thread::fault_handler use in C[++] code was broken with gcc 4. At least
when other functions were invoked. Trying to trick the compiler wasn't a
particularly good idea anyway, since the next compiler version could break
the trick again. So the general policy is to use the fault handlers only in
assembly code where we have full control. Changed that for x86 (save for the
vm86 mode, which has a similar mechanism), but not for the other
architectures.
* Introduced fault_handler, fault_handler_stack_pointer, and fault_jump_buffer
fields in the cpu_ent structure, which must be used instead of
thread::fault_handler in the kernel debugger. Consequently user_memcpy() must
not be used in the kernel debugger either. Introduced a debug_memcpy()
instead.
* Introduced debug_call_with_fault_handler() function which calls a function
in a setjmp() and fault handler context. The architecture specific backend
arch_debug_call_with_fault_handler() has only been implemented for x86 yet.
* Introduced debug_is_kernel_memory_accessible() for use in the kernel
debugger. It determines whether a range of memory can be accessed in the
way specified. The architecture specific back end
arch_vm_translation_map_is_kernel_page_accessible() has only been implemented
for x86 yet.
* Added arch_debug_unset_current_thread() (only implemented for x86) to unset
the current thread pointer in the kernel debugger. When entering the kernel
debugger we do some basic sanity checks of the currently set thread structure
and unset it, if they fail. This allows certain commands (most importantly
the stack trace command) to avoid accessing the thread structure.
* x86: When handling a double fault, we do now install a special handler for
page faults. This allows us to gracefully catch faulting commands, even if
e.g. the thread structure is toast.
We are now in much better shape to deal with double faults. Hopefully avoiding
the triple faults that some people have been experiencing on their hardware
and ideally even allowing to use the kernel debugger normally.
