2007-11-05drm: remove lots of spurious whitespace.Dave Airlie
Kernel "cleanfile" script run.
2007-11-05drm: move some of the OS stuff into the OS headerDave Airlie
2007-11-04nouveau: more nv20_graph_init.Pekka Paalanen
This patch is originally from malc0_, but since it used some NV40_* regs, I edited them into hex values with a comment. This seems to correspond quite well with my own mmio-trace, for the parts I cared to check.
2007-11-05nouveau: Use a sw method instead of notify interrupt to signal fence completion.Ben Skeggs
2007-11-05nouveau: disable m2mf buffer move for the momentBen Skeggs

2007-11-02nouveau: more filling in for ttm. Change copyright since it's based off of ↵Jeremy Kolb
radeon code.
2007-11-02User buffer support.Thomas Hellstrom
2007-11-02Return fence errors.Thomas Hellstrom
Time out properly in the presence of signals.
2007-11-03radeon: set the address to access the aperture on the CPU side correctlyDave Airlie
This code relied on the CPU and GPU address for the aperture being the same, On some r5xx hardware I was playing with I noticed that this isn't always true. I wonder if this will fix some of those r4xx DRI issues we've seen in the past.
2007-11-01Use unsigned long instead of u64 in drm_modeset_ctl_tJesse Barnes
A bad idea, ABI-wise, but we're going to be changing this structure anyway before we merge upstream, so just fix the build for now.
2007-11-01Cleanup vblank_init and fix drm_irq_installJesse Barnes
The vblank_init function wanted a couple of cleanups. Also, drm_irq_install wasn't checking the new return value of irq_postinstall. If it returns a failure, assume IRQs didn't get set up and take appropriate action.
2007-11-01nouveau: don't use AGP on PPC. It's a hopeless case.Stephane Marchesin
2007-10-31nouveau: add missing file.Jeremy Kolb
2007-10-31Merge branch 'master' of git+ssh://git.freedesktop.org/git/mesa/drmJeremy Kolb
2007-10-31nouveau: ttm stubsJeremy Kolb
2007-11-01drm/ttm: add support for cached un-snooped mappings.Dave Airlie
This mapping allows cached objects to be mapped in/out of the TT space with the appropriate flushing calls. It should put back the old CACHED functionality for snooped mappings
2007-11-01i915: fix compat code on 965/g33Dave Airlie
2007-10-31drm: add chipset flushing via agp supportDave Airlie
2007-10-31i915: add backwards compat chipset flushing codeDave Airlie
2007-10-31drm: call driver load after initing agp subsystemDave Airlie
2007-10-30Merge branch 'master' into vblank-rework, fixup remaining driversJesse Barnes
Conflicts: linux-core/drmP.h linux-core/drm_drv.c linux-core/drm_irq.c shared-core/i915_drv.h shared-core/i915_irq.c shared-core/mga_drv.h shared-core/mga_irq.c shared-core/radeon_drv.h shared-core/radeon_irq.c Merge in the latest master bits and update the remaining drivers (except mach64 which math_b is working on). Also remove the 9xx hack from the i915 driver; it seems to be correct.
2007-10-30Nouveau: add a comment about SKIPS for next API breakage.Stephane Marchesin
2007-10-30Nouveau: fold some loops.Stephane Marchesin
2007-10-30drm/i915: add driver cache flush entry pointDave Airlie
Use clflush on Intel hardware to flush cached objects.
2007-10-29Move struct drm_drawable_info out of public header file.Kristian Høgsberg
2007-10-29Remove unused memory save areasJesse Barnes
These need to be kmalloc'd separately anyway or we may hit kmalloc size limits.
