freebsd-skq/sys/dev/drm/radeon_cp.c
anholt 3de8a0378f Update DRM to CVS snapshot as of 2005-11-28. Notable changes: 
- S3 Savage driver ported.
- Added support for ATI_fragment_shader registers for r200.
- Improved r300 support, needed for latest r300 DRI driver.
- (possibly) r300 PCIE support, needs X.Org server from CVS.
- Added support for PCI Matrox cards.
- Software fallbacks fixed for Rage 128, which used to render badly or hang.
- Some issues reported by WITNESS are fixed.
- i915 module Makefile added, as the driver may now be working, but is untested.
- Added scripts for copying and preprocessing DRM CVS for inclusion in the
  kernel.  Thanks to Daniel Stone for getting me started on that.

* bufs until freelist code is used. Note this hides a problem with
* the scratch register * (used to keep track of last buffer
* completed) being written to before * the last buffer has actually
* completed rendering.
*
* KW: It's also a good way to find free buffers quickly.
*
* KW: Ideally this loop wouldn't exist, and freelist_get wouldn't
* sleep. However, bugs in older versions of radeon_accel.c mean that
* we essentially have to do this, else old clients will break.
*
* However, it does leave open a potential deadlock where all the
* buffers are held by other clients, which can't release them because
* they can't get the lock.
