Age	Commit message (Collapse)	Author
2005-04-16	Use /*- to begin license blocks in BSD code to reduce diffs against FreeBSD	Eric Anholt
	CVS.
2004-11-06	Move the lock/unlock ioctls to a more logical place, in drm_lock.c.	Eric Anholt

2004-11-06	Commit WIP of BSD conversion to core model. Compiles for r128, radeon, but	Eric Anholt
	doesn't run yet. Moves the ioctl definitions for these two drivers back to the shared code -- they aren't OS-specific.
2003-08-19	- Remove $FreeBSD$ tags as they weren't too useful and merges are now being	Eric Anholt
	done through perforce. - Add copyright headers to drm_os_*bsd.h, still need to research the other copyright-less files better.
2003-04-25	Merge from FreeBSD-current.	Eric Anholt

2003-04-24	Remove more gamma DMA code. This isn't all of it, but it's a major portion.	Eric Anholt

2003-04-24	Remove a bunch of dead code and fix spelling of a couple of comments.	Eric Anholt

2003-03-29	Add DRMFILE definitions and supply filp for BSD in the	Eric Anholt
	post-drm-filp-0-1-branch world. The filp is a void * cast from the current pid. This is a temporary solution which maintains the status quo until a proper solution is implemented. What is really needed is a unique pointer per open, hopefully with a device private area. This can be done in FreeBSD for all entry points except mmap, but is difficult (sys/dev/streams/streams.c is an example). I have partially completed code for this but have not had time to debug, so this is a temporary fix.
2003-03-11	Merge back from FreeBSD-current, adding FreeBSD ID tags to aid future	Eric Anholt
	merging. Also includes an update to radeon PCI IDs.
2003-02-21	Merge from bsd-4-0-0-branch.	Eric Anholt

2002-07-05	merged bsd-3-0-0-branch	Alan Hourihane

2002-01-27	Initial revision	David Dawes
