Chris Wilson cda4b7d3a5 drm/i915: Unset cursor if out-of-bounds upon mode change (v4)
The docs warn that to position the cursor such that no part of it is
visible on the pipe is an undefined operation. Avoid such circumstances
upon changing the mode, or at any other time, by unsetting the cursor if
it moves out of bounds.

"For normal high resolution display modes, the cursor must have at least a
single pixel positioned over the active screen.” (p143, p148 of the hardware
registers docs).

Fixes:

  Bug 24748 - [965G] Graphics crashes when resolution is changed with KMS
              enabled
  https://bugs.freedesktop.org/show_bug.cgi?id=24748

v2: Only update the cursor registers if they change.
v3: Fix the unsigned comparision of x,y against width,height.
v4: Always set CUR.BASE or else the cursor may become corrupt.

Chris Wilson 86f100b136 drm/i915: Unreference object not handle on creation
When creating an object, we create the handle by which it is known to
the process and which own the reference to the object. That reference to
the new handle is what we want to transfer to the process, not the lost
reference to the object; so free the local object reference *not* the
process's handle reference.

This brings i915_gem_object_create_ioctl() into line with
drm_gem_open_ioctl()

Chris Wilson 8dc1775dce drm/i915: Attempt to uncouple object after catastrophic failure in unbind
If we fail to flush outstanding GPU writes but return the memory to the
system, we risk corrupting memory should the GPU recovery and complete
those writes. On the other hand, if we bail early and free the object
then we have a definite use-after-free and real memory corruption.
Choose the lesser of two evils, since in order to recover from the hung
GPU we need to completely reset it, those pending writes should
never happen.

Chris Wilson be72615bcf drm/i915: Repeat unbinding during free if interrupted (v6)
If during the freeing of an object the unbind is interrupted by a system
call, which is quite possible if we have outstanding GPU writes that
must be flushed, the unbind is silently aborted. This still leaves the
AGP region and backing pages allocated, and perhaps more importantly,
the object remains upon the various lists exposing us to memory
corruption.

I think this is the cause behind the use-after-free, such as

  Bug 15664 - Graphics hang and kernel backtrace when starting Azureus
              with Compiz enabled
  https://bugzilla.kernel.org/show_bug.cgi?id=15664

v2: Daniel Vetter reminded me that kernel space programming is never easy.
We cannot simply spin to clear the pending signal and so must deferred
the freeing of the object until later.
v3: Run from the top level retire requests.
v4: Tested with P(return -ERESTARTSYS)=.5 from i915_gem_do_wait_request()
v5: Rebase against Eric's for-linus tree.
v6: Refactor, split and add a comment about avoiding unbounded recursion.

Chris Wilson 534843dabf drm/i915: Use 128k alignment for untiled display surface on i965 (v2)
The original i965, including the revised G35 and Q35, requires an
alignment of 128K for the display surface with linear memory, so
increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)

Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.

v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

On some machines (currently only the Toshiba Tecra A11 is known), the GPU

Dan Carpenter 167ffc44ca drm: radeon: fix sign bug
The "error" variable is unsigned so it's never less than zero.  I
changed it to check if (freq < current_freq) directly.

"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative.  Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.

Dave Airlie 4c712e6c7e drm/radeon/kms: check/restore sanity before doing anything else with GPU.
On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset.

Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system.

This allows kexec to work on a Power6/RN50 system.

that hotkeys such as the video switch key emit ACPI events when
pressed.

errata functions
- Use rdev->family rather than rdev->flags & RADEON_FAMILY_MASK for kms
- replace rn50 check using ids with ASIC_IS_RN50 convenience macro

Adam Jackson a4967de6cb drm/edid: Fix the HDTV hack sync adjustment
We're adjusting horizontal timings only here, moving vsync was just a
slavish translation of a typo in the X server.

Fix error from the last pull request.  Making sure we shut the panel off
is more correct and saves power.

Chris Wilson 0cc4d4300c drm/i915: Fix panel fitting regression since 734b4157
The crtc mode fixup is run after the encoders adjust the mode to fit on
their output, so don't reset the mode!

Jesse Barnes fbd41a7e58 drm/i915: fix deadlock in fb teardown
At module unload time we'll tear down the fbdev state.  We do so under
the struct mutex, so we shouldn't try to use the unlocked variant of
the GEM object unreference function or we may deadlock.

Chris Wilson 127bd2ac91 drm/i915: Use the correct scanout alignment for fbcon.
This fixes a potential modesetting error during boot with plymouth on
Broadwater and Crestline introduced with 9df47c. The framebuffer was
hard-coding an alignment of 64K, but the modesetting code required the
documented alignment of 128K. The result was that we would attempt to
unbind the pinned fbcon buffer, triggering an ERROR and ultimately
failing the mode change.
