drm/i915: fix 945 fence register writes for fence 8 and above.

2009-03-11T18:02:06+00:00

The last 8 fence registers sit at a different offset, so when we went to set
fence number 8 in the lower offset, we instead set PGETBL_CTL, and the GPU
got all sorts of angry at us.

fd.o bug #20567.  Easily reproducible by running glxgears and killing it about
6 times.

drm/i915: Protect active fences on i915

2009-03-11T17:33:28+00:00

The i915 also uses the fence registers for GPU access to tiled buffers so
we cannot reallocate one whilst it is on the active list. By performing a
LRU scan of the fenced buffers we also avoid waiting the possibility of
waiting on a pinned, or otherwise unusable, buffer.

drm/i915: Check to see if we've pinned all available fences

2009-03-11T03:32:13+00:00

We need to check and report if there are no available fences - or else we
spin endlessly waiting for a buffer to magically unpin itself.

drm/i915: Check fence status on every pin.

2009-03-11T03:25:32+00:00

As we may steal the fence register of an unpinned buffer for another,
every time we repin the buffer we need to recheck whether it needs to be
allocated a fence.

drm/i915: First recheck for an empty fence register.

2009-03-11T03:22:24+00:00

If we wait upon a request and successfully unbind a buffer occupying a
fence register, then that slot will be freed and cause a NULL derefrence
upon rescanning.

drm/i915: Don't restore palettes through VGA registers.

2009-03-10T20:11:12+00:00

The VGA registers just hit the pipe registers that we already set through
MMIO.  This fixes strange colors on resume.

i915: add newline to i915_gem_object_pin failure msg

drm: Return EINVAL on duplicate objects in execbuffer object list

2009-03-10T20:11:11+00:00

If userspace passes an object list with the same object appearing more
than once, we end up hitting the BUG_ON() in
i915_gem_object_set_to_gpu_domain() as it gets called a second time
for the same object.
