64b15ec174 Back out r261266 pending security buy-in.
r261266:
  Add a jail parameter, allow.kmem, which lets jailed processes access
  /dev/kmem and related devices (i.e. grants PRIV_IO and PRIV_KMEM_WRITE).
  This in conjunction with changing the drm driver's permission check from
  PRIV_DRIVER to PRIV_KMEM_WRITE will allow a jailed Xorg server.

658534ed5a Switch vm_object lock to be a rwlock.
* VM_OBJECT_LOCK and VM_OBJECT_UNLOCK are mapped to write operations
* VM_OBJECT_SLEEP() is introduced as a general purpose primitve to
  get a sleep operation using a VM_OBJECT_LOCK() as protection
* The approach must bear with vm_pager.h namespace pollution so many
  files require including directly rwlock.h

d39bb93731 Address some WITNESS panics that occur when using the via driver.
Some of these cases should be safe in a non-atomic fashion, however
since all of the driver ioctls are locked, a lot of work is required to
fix it correctly.  Just don't sleep now.

50a4503e46 re-write scatter gather memory allocation yet again...
This time, abandon the use of busdma and start interacting with the VM
system directly.  Make use of the new kmem_alloc_attr() which allows us
to easily allocate non-contiguous pages to back the GART table.  This
should help a lot when starting or restarting X after the system has
been running for a while and memory has become fragmented.

b733ebaa1c Rework how drm maps are handled.
* On 32 bit platforms we steal the upper 4 bits of the map handle
   to store a unique map id.
 * On 64 bit platforms we steal the upper 24 bits.

Resolves issues where the offsets that are handed to mmap may overlap the VRAM on some cards.

Tested on: radeon, intel, mga, and via.

This will break nouveau.  I will spin new patches shortly.

ddd5c68e84 Initialize the vblank structures at load time. Previously we did this
at irq install/uninstall time, but when we vt switch, we uninstall the
irq handler.  When the irq handler is reinstalled, the modeset ioctl
happens first.  The modeset ioctl is supposed to tell us that we can
disable vblank interrupts if there are no active consumers.  This will
fail after a vt switch until another modeset ioctl is called via dpms
or xrandr.  Leading to cases where either interrupts are on and can't
be disabled, or worse, no interrupts at all.

1b619f003f We only want drm to ever attach to the primary pci device.
Intel 855 chips present the same pci id for both heads.  This prevents
us from attaching to the dummy second head.  All other chips that I
am aware of either only present a single pci id, or different ids
for each head so that we only match on the correct head.

3e6eb1349a rework drm_scatter.c which allocates scatter / gather pages for use by
ati pci gart to use bus_dma to handle the allocations.  This fixes
a garbled screen issue on at least some radeons (X1400 tested).  It is
also likely that this is the correct fix for PR# 119324, though that
is not confirmed yet.

192b3600be 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.

bbc754f502 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.

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.

ed881e3d94 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.
