is controlled via ACPI methods.
4 combinations of systems typically exist - with 2 ACPI methods.
Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method
ATI/ATI - some ASUS - use ATPX ACPI Method
Intel/Nvidia - - use _DSM ACPI method
Nvidia/Nvidia - - use _DSM ACPI method.
TODO:
This patch adds support for the ATPX method and initial bits
for the _DSM methods that need to written by someone with
access to the hardware.
Add a proper non-debugfs interface - need to get some proper
testing first.
v2: add power up/down support for both devices
on W500 puts i915/radeon into D3 and cuts power to radeon.
v3: redo probing methods, no DMI list, drm devices call to
register with switcheroo, it tries to find an ATPX method on
any device and once there is two devices + ATPX it inits the
switcher.
v4: ATPX msg handling using buffers - should work on more machines
v5: rearchitect after more mjg59 discussion - move ATPX handling to
radeon driver.
v6: add file headers + initial nouveau bits (to be filled out).
v7: merge delayed switcher code.
v8: avoid suspend/resume of gpu that is off
v9: rearchitect - mjg59 is always right. - move all ATPX code to

drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page and beyond
radeon's have a special ability to passthrough writes in their internal
memory space directly to PCI, this ability means that if some of the internal
surfaces like the depth buffer point at 0x0, any writes to these will
go directly to RAM at 0x0 via PCI busmastering.
Now mesa used to always emit clears after emitting state, since the
radeon mesa driver was refactored a year or more ago, it was found it
could generate a clear request without ever sending any setup state to the
card. So the clear would attempt to clear the depth buffer at 0x0, which
would overwrite main memory at this point. fs corruption ensues.
Also once one app did this correctly, it would never get set back to 0
making this messy to reproduce.
The kernel should block this from happening as mesa runs without privs,
though it does require the user be connected to the current running X session.
This patch implements a check to make sure the depth offset has been set
before a depth clear occurs and if it finds one it prints a warning and
ignores the depth clear request. There is also a mesa fix to avoid sending
the badness going into mesa.
This only affects r100/r200 GPUs in user modesetting mode.

drm/i915: reuse i915_gpu_idle helper
We have it, so use it. This required moving the function to avoid
a forward declaration.

drm/i915: ensure lru ordering of fence_list
The fence_list should be lru ordered for otherwise we might try
to steal a fence reg from an active object even though there are
fences from inactive objects available. lru ordering was obeyed
for gpu access everywhere save when moving dirty objects from
flushing_list to active_list.
Fixing this cause the code to indent way to much, so I've extracted
the flushing_list processing logic into its on function.

drm/i915: extract fence stealing code
The spaghetti logic in there tripped up my brain's code parser for a
few secs. Prevent this from happening again by extracting the fence
stealing code into a seperate functions. IMHO this slightly clears up
the code flow.
v2: Beautified according to ickle's comments.
v3: ickle forgot to flush his comment queue ... Now there's also a
we-are-paranoid BUG_ON in there.
v4: I've forgotten to switch on my brain when doing v3. Now the BUG_ON
actually checks something useful.
v5: Clean up a stale comment as noted by Eric Anholt.

drm/i915: reuse i915_gem_object_put_fence_reg for fence stealing code
This has a few functional changes against the old code:
* a few more unnecessary loads and stores to the drm_i915_fence_reg
objects. Also an unnecessary store to the hw fence register.
* zaps any userspace mappings before doing other flushes. Only changes
anything when userspace does racy stuff against itself.
* also flush GTT domain. This is a noop, but still try to keep the
bookkeeping correct.

drm/i915: Add dependency on the intel agp module
See http://bugzilla.kernel.org/show_bug.cgi?id=15021
Make sure that the appropriate AGP module is loaded and probed before
trying to set up the DRM. The DRM already depends on the AGP core,
but in this case we know the specific AGP driver we need too, and can
help users avoid the trap of loading the AGP driver after the DRM
driver.
