2005-11-28Assert an MIT copyright on sis_drm.h, since one was lacking and I createdEric Anholt
that particular file. Its contents have changed a good bit since the original sis code, and the original sis code didn't care much about attribution since it routinely disclaims Precision Insight/VA Linux from responsibility. Also, adjust formatting around license headers (have a comment open immediately before the "Copyright" line, not as a runon of any previous comments) for automatic processing into FreeBSD, where /*- is used to signal the beginning of license headers for automatic compilation of license lists.
2005-11-11cleanup ioctl/max_ioctl to use header file for extern symbolsDave Airlie
2005-09-11Add GART in FB support for ati pcigart, and PCIE support for r300Dave Airlie
2005-08-05Rename the driver hooks in the DRM to something a little moreEric Anholt
understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
2005-07-16revert last change due to me bring up too earlyDave Airlie
2005-07-16up the versionDave Airlie
2005-06-29add mga and r128 32/64 bitsDave Airlie
This is Egberts code, ported to Pauls framework by me..
2005-02-01cleanup patch from Adrian Bunk <bunk@stusta.de>Dave Airlie
2004-09-30Lindent of core build. Drivers checked for no binary diffs. A few filesJon Smirl
weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.
2004-09-27First check in for DRM that splits core from personality modulesJon Smirl
2004-08-24Merged drmfntbl-0-0-2Dave Airlie
2004-08-17Merged drmfntbl-0-0-1Dave Airlie
2003-12-16Don't ioremap the framebuffer area. The ioremapped area wasn't used byEric Anholt
anything, and took up valuable KVA. While I'm in the area, clean up BSD MTRR stuff some more. Suggested by: jonsmirl
2003-10-16Introduce COMMIT_RING() as in radeon DRM, stop using error prone writebackMichel Daenzer
for ring read pointer (Paul Mackerras) Get rid of some superfluous stuff, minor fixes
2003-07-26Add Rage 128 pageflipping support, defaults to off. DRM version bump toEric Anholt
2.5.0. It still has some issues, including a flicker in the fps meter in tuxracer and I've seen garbage left behind after moving/closing windows. However, it's usable. Add the Option "EnablePageFlip" "YES" to use it.
2003-05-26Add support to r128 for MESA_ycbcr_texture (Ian Romanick, Leif Delgass)Leif Delgass
2003-04-26Remove the map argument from DRM_*MEMORYBARRIER. Not all of the uses ofEric Anholt
DRM_*MEMORYBARRIER we had were related to an MMIO space. This means arch-specific code on the BSDs, unfortunately. Also add DRM_MEMORYBARRIER() and change the DRM_READMEMORYBARRIER()s that used to be read/write barriers to it.
