Age	Commit message (Collapse)	Author
2008-02-13	start moving over to proper hierarchy wrt master accesses	Dave Airlie
2008-02-13	major port of multi-master ideas into modesetting	Dave Airlie
2007-11-22	drm: major whitespace/coding style realignment with kernel	Dave Airlie
2007-07-20	Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.	Eric Anholt
	The data is now in kernel space, copied in/out as appropriate according to the This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DRM is lost.
2007-07-20	Replace filp in ioctl arguments with drm_file *file_priv.	Eric Anholt
	As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.
2007-07-16	drm: detypedef drm.h and fixup all problems	Dave Airlie
2006-08-10	cleanup some whitespace issue and move compat code to compat header	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.
2006-06-23	Fix compilation problem on 2.6.9 kernels (bug #6211)	Alan Hourihane
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.
2006-02-18	major realigment of DRM CVS with kernel code, makes integration much easier	Dave Airlie
2005-06-04	misc cleanup patch from Adrian Bunk	Dave Airlie
2004-10-18	Update Doxygen configuration & comments.	Jose Fonseca
2004-10-12	Breakout heads into their own data structures.	Jon Smirl
2004-09-30	Lindent of core build. Drivers checked for no binary diffs. A few files	Jon 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.
2004-09-27	First check in for DRM that splits core from personality modules	Jon Smirl
2004-08-27	__NO_VERSION__ hasn't been needed since 2.3 days ditch it...	Dave Airlie
2004-07-20	first set of __user annotations from kernel (Al Viro)	Dave Airlie
2003-05-27	Merged DRM documentation.	Jose Fonseca
2002-02-14	First pass of mesa-4-0 branch merge into trunk.	David Dawes
