221478e4c6 We don't know what these pages are going to be used for, they should be
un-cached.  This got lost somewhere with all the bus_dma fixups.

254c58f9fd Change the flags to bus_dmamem around to allow it to sleep waiting for
resources during allocation, but not during map load.  Also, zero the
buffers here.

f00755f06b Rework memory allocation to allocate memory with different type names. This
will ease the identification of memory leaks as the OS will be able to track
allocations for us by malloc type.  vmstat -m will show all of the
allocations.

Convert the calls to drm_alloc() and friends, which are used in shared code
to static __inline__ while we are here.

4cd2e9581f resync to git master
This reverts a private patch which is causing issues with many Intel chipsets.
I will review that patch and see what we need to do to fix it up later, but
for the time being, we will just get these chips working again.

This update contains a lot of code cleanup and is post gem merge
(no, we don't have gem support).  It should prove much easier to read the
code now.  A lot of thanks goes to vehemens for that work.  I have adapted
the code to use cdevpriv for tracking per open file data.  That alleviates
the old ugly hack that we used to try and accomplish the task and helped to
clean up the open / close behavior a good bit.  This also replaces the hack
that was put in place a year or so ago to prevent radeons from locking up
with AIGLX enabled.  I have had a couple of radeon testers report that it
still works as expected, though I no longer have radeon hardware to test with
myself.  Other various fixes from the linux crew and Intel, many of
which are muddled in with the gem merge.

0020a2cded We should never call drm_pci_alloc() while holding locks, due the the
calls to bus_dma.  There were multiple paths that held different locks or
no locks at all. This patch ensures that all of the calling paths drop
their lock(s) before calling drm_pci_alloc().

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.

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.

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.
