453130d9bf sys/dev: minor spelling fixes.
Most affect comments, very few have user-visible effects.

7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

c8aef31d30 Similar to the (1 << 31) case it is not defined to do (2 << 30). 2013-11-30 22:16:37 +00:00

f588a0bda5 Add kernel support for Radeon R6/7xx 3D.
You will still need Mesa from git and possibly an updated DDX driver,
but this is working fairly well now.

4fcda8938e Import support for ATI Radeon R600 and R700 series chips.
Tested on an HD3850 (RV670) on loan from Warren Block.

Currently, you need one of the following for this to be useful:

	x11-drivers/xf86-video-radeonhd-devel (not tested)
	xf86-video-ati from git (EXA works, xv is too fast)
	xf86-video-radeonhd from git (EXA works, xv works)

There is no 3d support available from dri just yet.

a2a2d95441 Update drm kernel drivers.
This is a sync to mesa/drm pre-gem, with a few fixes on top of that.
It also contains one local patch supplied by kib@ that I can't apply to
git.master shared code.

72ab0eff0f Update to DRM CVS as of 2006-04-09. The most notable new feature is the updated
Radeon memmap code, which with a new DDX driver and DRI drivers should fix
long-term stability issues with Radeons.  Also adds support for r200's
ATI_fragment_shader, r300 texrect support and texture caching fixes, i915
vblank support and bugfixes, and new PCI IDs.

9fb0767374 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.

af088425f7 Add the latest r300 code from r300.sf.net. This is based on the patch supplied
by Vladimir Dergachev for inclusion in DRM CVS, with minor modifications for
FreeBSD CVS and the appropriate license from Nicolai Haehnle on r300_reg.h.
Fixes hangs when using r300.sf.net userland, tested on a Radeon 9600 on amd64.

b8aa843c63 Update to DRM CVS as of 2005-04-12, bringing many changes:
- Split core DRM routines back into their own module, rather than using the
  nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
  course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
  testbox).  Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
  to the drmsub device.  Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work.  Covers the
  Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.

suspend/resume support and Rage 128 pageflipping support (both of which require

43e2d1e384 Update the DRM to latest from DRI CVS. This is approximately the version
included in XFree86 4.3, but includes some fixes.  Notable changes include
Radeon 8500-9100 support, PCI Radeon/Rage 128 support, transform & lighting
support for Radeons, and vblank syncing support for r128, radeon, and mga.
The gamma driver was removed due to lack of any users.
