Age	Commit message (Collapse)	Author
2008-08-13	Merge branch 'master' into modesetting-gem	Jesse Barnes
	Conflicts: libdrm/Makefile.am libdrm/xf86drm.h shared-core/i915_dma.c shared-core/i915_irq.c
2008-08-11	drm: add OS_HAS_GEM option.	Dave Airlie
	To build i915 driver pass OS_HAS_GEM=1 to make for now
2008-07-09	Merge remote branch 'origin/modesetting-101' into modesetting-gem	Dave Airlie
2008-06-22	NV50: Initial import of kernel modesetting.	Maarten Maathuis
2008-06-18	Merge commit 'origin/drm-gem' into modesetting-gem	Jesse Barnes
	Lots of conflicts, seems to load ok, but I'm sure some bugs snuck in. Conflicts: linux-core/drmP.h linux-core/drm_lock.c linux-core/i915_gem.c shared-core/drm.h shared-core/i915_dma.c shared-core/i915_drv.h shared-core/i915_irq.c
2008-06-13	Use /bin/pwd instead of trusting shell built-in	Keith Packard
2008-06-11	Remove override of drm module list in preparation for merge.	Eric Anholt
2008-06-10	Merge commit 'origin/drm-gem' into modesetting-gem	Jesse Barnes
	Passed the compile test; it's ready to ship. Conflicts: libdrm/Makefile.am linux-core/Makefile.kernel linux-core/drmP.h linux-core/drm_memrange.c linux-core/drm_stub.c shared-core/drm.h shared-core/i915_dma.c shared-core/i915_drv.h shared-core/i915_irq.c
2008-05-29	modeset: disable radeon ms by default	Dave Airlie
	as I'm going to break it.
2008-05-05	Emit clflush and chipset flush when mapping objects to gtt	Keith Packard
2008-04-29	Remove the remainder of the mmfs device.	Eric Anholt
2008-04-28	Merge branch 'master' into modesetting-101	Thomas Hellstrom
	Conflicts: linux-core/Makefile.kernel linux-core/drm_compat.c linux-core/drm_fops.c linux-core/drm_lock.c shared-core/drm.h shared-core/i915_dma.c shared-core/i915_drv.h shared-core/i915_irq.c
2008-04-23	Initial add of mmfs module.	Eric Anholt
2008-04-22	linux-core Makefile: add GIT_REVISION	Pekka Paalanen
	This tries to automatically fetch a git revision string and if succeeds, it #defines GIT_REVISION string macro. Packagers can override it by 'make GIT_REVISION=foo'. Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE in struct drm_driver. Signed-off-by: Pekka Paalanen <pq@iki.fi>
2008-01-18	Made radeon_ms not always compile	Jakob Bornecrantz
2007-12-04	radeon_ms: radeon modesetting first commit.	Jerome Glisse
	This should work on all radeon but there is still many things todo: - add crtc2 - tmds - lvds - add bios data table so we don't need to hardcode dac/crtc infos - separate clock control to make power saving easier & cleaner - tiling (warning tiling shouldn't be enable in double scan or interlace) - surface reg manager (this goes along with tiling) - suspend/resume hook - avivo & r500 family support - atom bios support (for posting card mostly) - finish superioctl skeleton - what else ? :)
2007-10-17	Revert "Remove the pinned buffer from the LRU when pinning."	Thomas Hellstrom
	This reverts 3a0bc518e35c62bb9c64c9105f836584d949653f commit.
2007-09-29	Don't build without any optimization on Linux.	Michel Dänzer
	Building without optimization causes the drm module not to link correctly on ppc.
2007-09-26	Allow parallel module compile	Keith Packard
2007-09-19	Merge branch 'origin' into bo-set-pin	Eric Anholt
2007-08-02	Remove the pinned buffer from the LRU when pinning.	Eric Anholt
	Also, be a little safer with setting the pinned flag within the struct lock. I'm not 100% sure if this is required, but it seems like it might be.
2007-07-19	Initial pass at converting driver to DRM infrastructure.	Ian Romanick
2007-06-26	Add XGI driver to Makefiles.	Ian Romanick
2007-05-17	nouveau: don't build the module by default	Stephane Marchesin
2007-04-07	fixup install target, not sure what I was smokin...	Dave Airlie
2007-04-05	add an install target to the drm modules makefile	Dave Airlie
2007-03-19	Remove old i830 kernel driver.	Alan Hourihane
2006-12-20	Merge branch 'nouveau-1'	Dave Airlie
2006-12-20	fixup symlinks via Makefile	Dave Airlie
2006-12-19	drm: remove all 2.4 support for drm development tree.	Dave Airlie
	Bye bye 2.4 you served us well..
2006-12-01	Track linux-core symlinks in git.	Michel Dänzer
2006-10-15	Merge branch 'master' of git://anongit.freedesktop.org/git/mesa/drm into ↵	Stephane Marchesin
	nouveau-1
2006-09-28	Add support for tracking drawable information to core	Michel Dänzer
	Actually make the existing ioctls for adding and removing drawables do something useful, and add another ioctl for the X server to update drawable information. The only kind of drawable information tracked so far is cliprects.
2006-08-27	initial import of nouveau code from nouveau CVS	Dave Airlie
2006-06-06	Merge in the drm-sman-branch	Thomas Hellstrom
2006-02-18	major realigment of DRM CVS with kernel code, makes integration much easier	Dave Airlie
2005-10-06	Skeleton nv drm driver, to enable DMA in EXA. (Lars Knoll, minor updates by	Adam Jackson
	me)
2005-09-11	fix makefile bug	Dave Airlie
2005-07-20	Add latest r300 support from r300.sf.net CVS. Patch submitted by volodya,	Eric Anholt
	with BSD fix from jkim and the r300_reg.h license from Nicolai Haehnle. Big thanks to everyone involved!
2005-06-29	Remove the AGP requirement from Makefile and Kconfig for MGA. Remove the	Ian Romanick
	AGP requirement from Kconfig for SIS. There never was a requirement in Makefile, and Eric Anholt confirms that the Makefile was correct.
2005-06-29	Move to linux specific directory	Alan Hourihane
2005-05-17	Savage doesn't require AGP any more. Enable build even without CONFIG_AGP.	Felix Kuehling
2005-03-28	Via updates:	Thomas Hellstrom
	New PCI command parser. Moved from via_dma.c to via_verifier.c so functions with similar functionality are close to eachother. Moved video related functions to via_video.c, which might be extended in the future, as new video functionality is added. New device-specific generic IRQ IOCTL, similar to the general VBLANK IOCTL, but with support for multiple device IRQ sources and functionality. Support for Unichrome Pro PM800/CN400 video DMA commands in verifier and PCI parser. Support for Unichrome Pro PM800/CN400 HQV IRQs in the new generic IRQ IOCTL. Bumped minor. New version 2.6.0.
2005-01-19	Fix cut & paste problem	Alan Hourihane
2005-01-07	via updates: moved the verifier state struct to dev_priv. Implemented AGP	Thomas Hellstrom
	alignment check.
2005-01-01	Completeley rewritten Savage DRM which can be considered secure (modulo	Felix Kuehling
	implementation errors). Direct hardware (MMIO, BCI) access is no longer needed in the Mesa driver. Bumped version to 2.0.0. Corresponding changes to the DDX and Mesa drivers are being committed.
2004-12-03	Added 3D functionality to the via command verifier. Modified the via	Thomas Hellstrom
	ring-buffer code somewhat to workaround hardware problems. Bumped via minor version number.
2004-09-30	Remove unused drm_module.h	Jon Smirl
2004-09-27	First check in for DRM that splits core from personality modules	Jon Smirl
2004-09-27	Flip the 2.4 check so that it looks for 2.6 instead. This will allow builds	Jon Smirl
	where we can't determine the version through.
