0x00 EXE fence. Signals when command stream interpreter has reached the point
where the fence was emitted.
0x01 FLUSH fence. Signals when command stream interpreter has reached the point
where the fence was emitted, and all previous drawing operations have been
completed and flushed.
Implements busy wait (for fastest response time / high CPU) and
lazy wait (User interrupt or timer driven).

This is a patch prepared by Guangdeng Liao based off of Tungsten Graphics's
final code drop.

This reverts af7b89d7246efbed7d05c38fcaa6a13c4b89db90 commit. It causes an oops
on X server shutdown here, and for the reporter of bug #7629 as well.

Commit 2a47f6bfecea5dabcbf79d5e1aaf271f50070b89 caused the CHIP_IS_AGP flag to
get 'restored' with PCI(e) cards. I can't think of a way to fix this without
introducing a (otherwise redundant) CHIP_IS_PCI flag.

The latter seems to be a read-only mirror of the former.
|
|
This allows using AGP after overriding to PCI mode in a previous session
without reloading the DRM.
|
|
Not doing this might waste bus bandwidth or even cause memory corruption or
system crashes on systems that check bus transfers. No such incident has been
reported though.
|
|
When this succeeds, userspace can read the scratch register contents from the
mapped writeback page directly.
|
|
|
|
Sort the merged file, remove the redundant explicit .ko lines and add
some generated symlinks.

32-bit physical device addresses are mapped directly to user-tokens. No
duplicate maps are allowed, and the addresses are assumed to be outside
of the range 0x10000000 through 0x30000000. The user-token is identical
to the 32-bit physical start-address of the map.
64-bit physical device addressed are mapped to user-tokens in the range
0x10000000 to 0x30000000 with page-size increments. The user_token should
not be interpreted as an address.
Other map types, like upcoming TTM maps are mapped to user-tokens in the
range
0x10000000 to 0x30000000 with page-size increments. The user_token should
not be interpreted as an address.
This keeps compatibility with buggy drivers, while still implementing a
hashed map lookup. The SiS and via device driver major bumps are
reverted.

0x10000000 to 0x90000000 in PAGE_SIZE increments.
Implement hashed map lookups.
This potentially breaks both 2D and 3D drivers. If so, the corresponding
2D and 3D driver should be fixed, and it's corresponding drm device driver
should have its major bumped as soon as possible.
Bump sis and via drm device driver majors.
The SiS and Unichrome 3D drivers are fixed in Mesa CVS HEAD and
mesa_6_4_branch.

i915 vblanks can be generated from either pipe a or b, however a disabled
pipe generates no interrupts. This change allows the X server to select
which pipe generates vblank interrupts.

more problems with flickering (bug #6637). drm may not be appropriate
place for this, since doing that flush there might both be overkill and
insufficient in some cases. However, it's hard to figure out when that
flush is needed, so this has to suffice. There does not seem to be a
performance penalty associated with it.

parameter matching the ioctl's command size there, since the copin/out
happened earlier.

though. Remove ids not known by ddx (secondary ids, non-existant,...).
Correct some entries (name/family). Make the radeon family enum look
more alike the ddx/dri versions. See #5413
