| | | | | | | | | | | | | | | | | | | | | | Previous to the last GTT rework we always rewrote the GTT then unmapped the object, somehow this got reversed in the rework in 2.6.37-rc5 timeframe. This fix needs to go to stable in an alternate form since the code changed. This fixes DMAR reports on my Ironlake HP2540p. Signed-off-by: Dave Airlie <airlied@redhat.com>

| | * drm/i915/execbuffer: Reorder binding of objects to favour restrictionsChris Wilson2011-01-112-26/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the mappable portion of the aperture is always a small subset at the start of the GTT, it is allocated preferentially by drm_mm. This is useful in case we ever need to map an object later. However, if you have a large object that can consume the entire mappable region of the GTT this prevents the batchbuffer from fitting and so causing an error. Instead allocate all those that require a mapping up front in order to improve the likelihood of finding sufficient space to bind them. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
| | * drm/i915: If we hit OOM when allocating GTT pages, clear the apertureChris Wilson2011-01-111-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than evicting an object at random, which is unlikely to alleviate the memory pressure sufficient to allow us to continue, zap the entire aperture. That should give the system long enough to recover and reap some pages from the evicted objects, forestalling the allocation error for the new object.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to retire active buffers whilst no client is active, we need to insert our own flush requests onto the ring. This is useful for servers that queue up some rendering and then go to sleep as it allows us to the complete processing of those requests, potentially making that memory available again much earlier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dave Airlie spotted that his ILK laptop with DMAR enabled was generating the occasional DMAR warning. "The ordering in the previous code was to rewrite the GTT table before unmapping the pages and that makes sense to me." This is his stable patch ported to d-i-n.

Adds a debugfs file to check current RC state, adds a missing workaround for Ironlake MI_SET_CONTEXT instructions, and renames MCHBAR_RENDER_STANDBY to RSTDBYCTL to match the docs. Keep RC6 and the power context disabled on pre-ILK. It only seems to hang and doesn't save any power.
