2006-08-07	drm: whitespace cleanup in new files	Dave Airlie
2006-08-07	drm: remove extra whitespace from drm_mm.c	Dave Airlie
2006-08-07	drm: fixup whitespace and style for Linux kernel import	Dave Airlie
2006-07-26	Revert "Make sure busmastering gets disabled on module unload."	Michel Dänzer
	This reverts af7b89d7246efbed7d05c38fcaa6a13c4b89db90 commit. It causes an oops on X server shutdown here, and for the reporter of bug #7629 as well.
2006-07-26	Bug #7629: Fix for CHIP_IS_AGP getting 'restored' with non-AGP cards	Michel Dänzer
	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.
2006-07-24	remove incorrect exit marking on cleanup pci as this is called from other paths	Dave Airlie
2006-07-24	switch drm to use Linux mutexes instead of semaphore.	Dave Airlie
	I hope the fallback compat code works if not shout at me.
2006-07-19	Delete the pre-core DRM code with extreme prejudice.	Adam Jackson
2006-07-19	Make sure busmastering gets disabled on module unload.	Adam Jackson
2006-07-19	Use RADEON_RB3D_DSTCACHE_CTLSTAT instead of RADEON_RB2D_DSTCACHE_CTLSTAT.	Michel Dänzer
	The latter seems to be a read-only mirror of the former.
2006-07-19	Make sure CHIP_IS_AGP flag is set when not overriding to PCI mode.	Michel Dänzer
	This allows using AGP after overriding to PCI mode in a previous session without reloading the DRM.
2006-07-19	When writeback isn't used, actually disable it in the hardware.	Michel Dänzer
	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.
2006-07-19	Implement RADEON_PARAM_SCRATCH_OFFSET getparam.	Michel Dänzer
	When this succeeds, userspace can read the scratch register contents from the mapped writeback page directly.
2006-07-19	Some debug output when the getparam ioctl is called with an unknown parameter.	Michel Dänzer
2006-07-19	.cvsignore -> .gitignore	Michel Dänzer
	Sort the merged file, remove the redundant explicit .ko lines and add some generated symlinks.
2006-07-11	Keep hashed user tokens, with the following changes:	Thomas Hellstrom
	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.
2006-07-10	Change drm Map handles to be arbitrary 32-bit hash tokens in the range	Thomas Hellstrom
	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.
2006-07-05	SiS 315 Awareness.	Thomas Hellstrom
2006-07-05	Add missing semaphore release.	Thomas Hellstrom
2006-06-27	Disable building static libraries. Bump to 2.0.2 for header updates.	Adam Jackson
2006-06-23	Fix compilation problem on 2.6.9 kernels (bug #6211)	Alan Hourihane
2006-06-22	Remove spurious debug messages from i915 vblank config paths	Keith Packard
2006-06-21	i915: Save vblank pipe configuration to restore on resume	Keith Packard
2006-06-19	Add i915 ioctls to configure pipes for vblank interrupt.	Keith Packard
	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.
2006-06-19	Fix buffer cleanup on close. Move memory manager reset from final_context	Thomas Hellstrom
	to lastclose.
2006-06-19	via: Bump version number and date.	Thomas Hellstrom
2006-06-16	via: Return the requested size instead of the correct size of the allocated	Thomas Hellstrom
	regions. The 2D driver and XvMC lib has problems when the returned size is not the same as the allocated size.
2006-06-15	via:	Thomas Hellstrom
	-Remove out of memory error message. -Move sman cleanup from final_context to lastclose. -Add the P4VM800PRO (?) PCI ID.
2006-06-06	s/list_entry/drm_hash_entry/ for "drm_hash_item"s.	Thomas Hellstrom
2006-06-06	Fix drm_remove_magic potential memory leak / corruption. Move drm	Thomas Hellstrom
	authentication token hashing to new generic hash table implementation.
2006-06-06	Merge in the drm-sman-branch	Thomas Hellstrom
2006-05-28	file via_mm.c was initially added on branch drm-sman-branch.	Thomas Hellstrom
2006-05-28	file drm_sman.h was initially added on branch drm-sman-branch.	Thomas Hellstrom
2006-05-28	file sis_mm.c was initially added on branch drm-sman-branch.	Thomas Hellstrom
2006-05-28	file drm_sman.c was initially added on branch drm-sman-branch.	Thomas Hellstrom
2006-05-26	file drm_hashtab.h was initially added on branch drm-ttm-branch.	Thomas Hellstrom
2006-05-24	Add support for r200 vertex programs (R200_EMIT_VAP_PVS_CNTL, and new	Roland Scheidegger
	packet type for making it possible to address whole tcl vector space and have a larger count)
2006-05-20	add forgotten register define for previous commit	Roland Scheidegger
2006-05-20	Do a tcl state flush before accessing tcl vector space. This fixes some	Roland Scheidegger
	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.
2006-05-19	rip out unneeded back compat code	Dave Airlie
2006-05-18	add consts to radeon microcode.	Dave Airlie
	From: tilman
2006-05-17	Set entry->virtual for sg maps, fixing ATI PCI/PCIE GART support.	Eric Anholt
	PR: kern/97056 Submitted by: Stanislav Sedov <ssedov@mbsd.msk.ru>
2006-05-17	Add the bits for vblank support on FreeBSD, which most importantly avoids	Eric Anholt
	chasing a NULL pointer at the first 3d app invocation.
2006-05-17	Add the workaround that's in the kernel to suppress GCC's warning about	Eric Anholt
	refusal to inline functions that (in some cases, at least) aren't that large.
2006-04-23	fixup GFP_COMP for older kernels and get_page/put_page for newer	Dave Airlie
2006-04-23	Fix from Benh for ppc r300 scratch	Dave Airlie
2006-04-20	check for __FreeBSD_kernel__ (bug 3810)	Brian Paul
2006-04-18	Err, use "ifndef" rather than "if !", to avoid compiler warning.	Eric Anholt
2006-04-18	Reorder the DRM_*_AGP enum to match linux's numbers (oops). Fixes i915	Eric Anholt
	attachment. Make our mga_drv.c use them, while I'm here. Submitted by: Jonathan Fosburgh <jonathan@fosburgh.org>
2006-04-18	Use __LP64__ instead of checking the linux-specific BITS_PER_LONG.	Eric Anholt
