resized but still had dirty pages to be written back,
vm_cache_resize() (which is called with the inode lock being held)
deadlocked with the page writer.
* Now, I reintroduced busy_writing: it'll be set by everything that
writes back pages (vm_page_write_modified(), and the page writer),
and will be checked for in vm_cache_resize() - other functions are not
affected for now, AFAICT.
* vm_cache_resize() will clear that flag, and the writer will check it
again after it wrote back the page (which will fail when it's outside
the file bounds), and if it's cleared, it will get rid of the page
(if the file has been resized again in the mean time, writing it will
succeed then, and we'll keep the page around).

appear: when freeing a modified page, it wouldn't have a cache
anymore, but set_page_state_nolock() depended on it.
* To work around this, I added a vm_page_free() function, which the
caches that free modified pages have to call (but others may, too).
It will correctly maintain the sModifiedTemporaryPages counter in case
the cache has already been removed.

Moved GetMouse() calls near the check for exit conditions.
Reorganized a bit the code, and hopefully simplified it in some places.

* Implemented mapping the GTT area for i9xx chips other than the i965. This should also fix the
driver working with these chips at all.
* The memory used by the driver now take the GTT area into account - before the GTT could be
overwritten theoretically...
* Added fix for some i965 quirks from the X driver.
* Added some overlay definitions for the i965.
* Started support for G33 overlay (not complete yet).

Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).

- in order to set cursor position SVGA_CURSOR_ON_SHOW has to be written to register SVGA_REG_CURSOR_ON.
- do not use alpha cursor because it does not support inverting of source pixels.
- Fixed wrong usage of if-statement inside switch-statement
- Sync at end of SCREEN_TO_SCREEN_BLIT so that app_server does not write to frame buffer while accelerated operation is still running.

* Implemented MakeSpace() (not yet tested).
* Changed intel_wait_engine_idle() to spin() between reads and to timeout
after 1 second of waiting (could probably be done way earlier).

* ACPI is evaluated first as it also handles things like multi core or hyper threading setups
* Removed other (disabled) hyper threading code per the notes in the corresponding ToDo
* Limit the detected CPU count to 2 for now as I wasn't able to get it working in either emulation nor real hardware with more than 2 CPUs
* Added a reserved byte to the mp_config_table struct, it worked only by luck as the compiler did padding there to get to the same size
I can now boot my Core 2 Quad with two out of four processors active :-)

* Therefore, I've added an I/O control that let's it update the boot block
part of this block, so that makebootable can use it on a mounted volume
(this will probably be moved into a disk system API later).
* Added user_memcpy() to the fs_shell.
* Minor cleanup.

passes that information on to the kernel. This should fix wrong bytes per row with
certain resolutions and graphics cards.
* The boot loader now recognizes 15 bit modes that are advertised as 16 bit modes.
This should fix wrong colors in 16 bit modes on some cards.
* Reenabled setting MTRR for VESA mode - don't remember why I disabled it, but it
works fine on my test machines.

serial output, and puts it into the new kernel_args::debug_output field.
* syslog_init() will now check if there is anything in kernel_args::debug_output
and will put that into the syslog buffer.
* dump_block() now also prints an offset.
* Fixed warning in mmu.cpp.

* The debug_server now sends the registrar messages whenever the debug alert
is shown, and also, if the user wants to debug the team.
* In the latter case, the registrar will now cancel a shutdown process.
* Also, it will now wait with the shutdown process until the user has
acknowledged the debugger alert.

* the flags,
* and the disk geometry - and that now allows the session add-on to actually
detect a newly inserted CD.

* file_map_translate() now cuts down the request to the file bounds.
* Adjusted BFS and FAT to the API changes.

device geometry.
* If SetTo() reports no media, and GetGeometry() fails, the device geometry
is now reset as well.
* KDiskDeviceManager::_ScanPartition() no longer unmarks the partition busy;
this is now done by the caller, and done independently from the outcome of
_ScanPartition(). This also fixes the problem that devices with no media
were never marked unbusy (and thus were ignored subsequently).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22912 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added vfs_unmount(), which allows unmounting by dev_t (used by the DDM).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22910 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Unmount when uninitializing a partition.
* Finished the media checker implementation, i.e. we rescan when a media
was inserted and uninitialize when ejected.
* Turned the disk device media checker from a kernel daemon into a thread.

that can be used by file systems.
* Changed the way the file cache works: instead of reading/writing to the
underlying device directly, it can now be used for any data source, ie.
also network file systems.
* As a result, the former pages_io() moved to the VFS layer, and can now be
called by a file system via {read|write}_file_io_vec_pages() (naming
suggestions are always welcomed :-)). It now gets an FD, and uses that to
communicate with the device (via its fs_{read|write}_pages() hooks).
* The file_cache_{read|write}() functions must now be called without holding
an I/O relevant file system lock. That allows the file cache to prepare the
pages without colliding with the page writer, IOW the "mayBlock" flag can
go into the attic again (yay!).
* This also results in a much better performance when the system does I/O and
is low on memory, as the page writer can now finally write back some pages,
and that even without maxing out the CPU :)
* The API changes put slightly more burden on the fs_{read|write}_pages()
hooks, but in combination with the file_map it's still pretty straight
forward. It just will have to dispatch the call to the underlying device
directly, usually it will just call its fs_{read|write}_pages() hooks
via the above mentioned calls.
* Ported BFS and FAT to the new API, the latter has not been tested, though.
* Also ported the API changes to the fs_shell. I also completely removed its
file cache level page handling - the downside is that device access is no
longer cached (ie. depends on the host OS now), the upside is that the code
is greatly simplified.

actually forgot to commit the changes I made to the ide_adapter...
* the IDE bus master command/status stuff is now used via flags; it's no
bitfield anymore.
* Changed a few constants to upper case.

K{Disk,File,Partitioning}System writing methods. It is now required
that the caller has marked the concerned partitions busy, hence we can
(read-)access them without needing a lock. The module interfaces will
will be changed to take advantage of the fact as well. The methods take a
disk_job_id instead of a KDiskDeviceJob* now, though I haven't quite
decided, whether we need it at all or just want to add a special
handling in the cases where notifications during the operation make
sense.
* Reimplemented the disk device write support syscalls (save
_user_move_partition() for which other module hooks are needed). They
call the KDiskSystem methods, now.

synchronous scanning is supported.
* Removed the disk device job support from the disk device manager.
* K{Disk,File,Partitioning}System:
- Remove querying and validation methods.
- Commented out the modification methods until their fate is decided.
* Removed obsolete _user_get_partitionable_spaces().

(_kern_{supports,validate}_*(), etc.).
* Adjusted the prototypes of the disk device modification syscalls.
Commented out their implementations for the time -- they'll mostly
have to be rewritten completely.
* Implemented the userland disk device jobs.

acceleration works fine, but overlay doesn't - that's next on my list.
Turns out the i965 differentiates between RGB-32 and RGB-32-alpha, and
didn't like trying to use the latter as display mode (the i865 didn't
care at all)... finding that took me *way* too long, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22780 a95241bf-73f2-0310-859d-f6bbb57e9c96

completed the implementation of the job generator.

We will use SRP (supervisor root pointer) register to hold the current thread pointer.
Its use by the pmmu is optional and I don't plan on using it.
There are 32 other bits left.
Wonder if weshouldn't use it for system_time() instead... will see, but there are no other usable regs.

next/prev link order - that messed up the DoublyLinkedListCLink adapter.
* Since it's more likely that someone messes with the C version, the C++ version
now uses the same order than that one.
* This fixes a bug when TCP's BufferQueue tried to iterate over a list, messing
up its integrity.
