drm/i915/selftests: Silence compiler warning in igt_ctx_exec

2017-05-24T12:34:22Z

The compiler doesn't always spot the guard that object is allocated on the first pass, leading to: drivers/gpu/drm/i915/selftests/i915_gem_context.c: warning: 'obj' may be used uninitialized in this function [-Wuninitialized]: => 370:8 v2: Make it more obvious by setting obj to NULL on the first pass and any later pass where we need to reallocate.

dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro

2017-04-20T08:17:46Z

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro in highmem.h, the former can be aliased if any dma-buf user includes that header. I'm personally trying to include highmem.h inside scatterlist.h and this breaks the dma-buf code proper. Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP. To maintain consistency I've renamed all four of kmap* and kunmap* to be map* and unmap*. (Even though only kmap_atomic presently conflicts.)

drm/i915: Clear gt.active_requests before checking idle status

2017-03-31T20:08:22Z

commit 8490ae207f1d ("drm/i915: Suppress busy status for engines if wedged") moved the check for inflight requests to the intel_engines_are_idle() check to protect the idle worker. However, the request selftests were also checking the engine idle status and erroring out if they did not become idle within a short period of time after the final wait. In order to accommodate the new check, call retire requests prior to the engine check so that we flush all the waits.

drm/i915: Move retire-requests into i915_gem_wait_for_idle()

2017-03-31T11:03:46Z

As we now distinguish everywhere that can call i915_gem_retire_requests() following a successful wait_for_idle, we can remove the duplication by moving that call into i915_gem_wait_for_idle() itself.

drm/i915: Remove intel_ring.last_retired_head

2017-03-21T14:21:50Z

Storing the position of the breadcrumb of the last retired request as a separate last_retired_head is superfluous as we always copy that into head prior to recalculation of the intel_ring.space.
