This is the same value as before, but it just makes the code slightly more readable to use the local variable than converting the aperture size into bytes every time. Signed-off-by:Chris Wilson <chris@chris-wilson.co.uk>

More precisely: For those that _need_ to be mappable. Also add two BUG_ONs in fault and pin to check the consistency of the mappable flag. Changes in v2: - Add tracking of gtt mappable space (to notice mappable/unmappable balancing issues). - Improve the mappable working set tracking by tracking fault and pin separately. Signed-off-by:

This way we can make some more educated guesses as to why exactly we can't use 2G apertures to their full potential ;) Signed-off-by:

On VT-d supporting platforms the GGTT is allocated in a stolen mem section separate from graphcis stolen mem. The GMCH register contains a bitfield specifying the size of that region. Docs suggest that this region can only be used for GGTT and PPGTT. Hence ensure that the PPGTT is disabled and use the complete area for the GGTT. Unfortunately the graphics core on G33/Pineview can't cope with really large GTTs and the BIOS usually enables the maximum of 512MB. So don't bother with maximizing the GTT on these platforms.

... and switch to a more classical store-reg-on-suspend, restore-on-resume way of doing things. Obviously this is just preparation for the future, the code is not there at all, yet. This is needed because the next patch adjusts this register and everything in it (not just the pagetable address) needs to be restored on resume. Signed-off-by:

In i915_gem_object_pin obviously unbind only if mappable is true. This is the last part to enable gtt_mappable_end != gtt_size, which the next patch will do. v2: Fences on g33/pineview only work in the mappable part of the gtt. Signed-off-by:

Like before add a parameter mappable (also to gem_object_pin) and set it depending upon the context. Only bos that are brought into the gtt due to an execbuffer call can be put into the unmappable part of the gtt, everything else (especially pinned objects) need to be put into the mappable part of the gtt.

Daniel Vetter authored
Add a mappable parameter to i915_gem_evict_something to distinguish the two cases (non-restricted vs. mappable gtt allocations). No functional changes because the mappable limit is set to the end of the gtt currently. Signed-off-by:

Currently, we believe the GPU is idle if just the RENDER ring is idle. This is obviously wrong if we only using either the BLT or the BSD rings and so masking genuine hangs. Signed-off-by: -

In the event that we fail to dispatch the execbuffer, for example if there is insufficient space on the ring, we were leaving the objects in an inconsistent state. Notably they were marked as being in the GPU write domain, but were not added to the ring or any list.

Preparing the ringbuffer for adding new commands can fail (a timeout whilst waiting for the GPU to catch up and free some space). So check for any potential error before overwriting HEAD with new commands, and propagate that error back to the user where possible. Signed-off-by: -

The ringbuffer keeps a pointer to the parent device, so we can use that instead of passing around the pointer on the stack. Signed-off-by: -
