51e39089c9 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.

67f435f03e The i915 driver was the only consumer of locked task support.
Now that it doesn't use it anymore, get right of the taskqueue

a87b4f7293 There is no reason to hold the lock here.
When I was LOCK_PROFILING this was pretty high up and there is no
reason for it.

c9e7b21284 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.

cdab8377da Replace calls to minor() with dev2unit(). Ed already fixed this once,
but I inadvertently overwrote the change when I synced to git.  Commit
the fix in both places, so this doesn't happen again.

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.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

ac165058b7 We need to lock around driver unload now.
The i915 driver installs it's register map at load time now.  We can't
remove the map during unload without holding the lock.

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.

149e9017bd Dont accidentally remove a filesocket which is still in use. This gives
problems when the DRM driver is loaded and the AIXGL extension is loaded
, the AIXGL driver requests a drm_close and this will cause the radeon
driver to fail while starting X windows.

90e545e597 Merge from DRM upstream:
- Add support for Intel 965 Express chipsets.
- Add support for R200 vertex programs, along with minor bugfixes.
- Add support for vblank synchronization to pipe B of Intel hardware
  (laptop screens).

e9aa66d283 - Bump FreeBSD version for the hostb(4) and vgapci(4) drivers as well as
the addition of pci_find_extcap().
- Change the drm drivers to attach to vgapci.  This is #ifdef'd so the
  code can be shared across branches.
- Use pci_find_extcap() to look for AGP and PCIE capabilities in drm.
- GC all the drmsub stuff for i810/i830/i915.  The agp and drm devices are
  now both children of vgapci.

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.
