Introduce a gem migrate interface, add a selftest and use it for display fb pinning and dma-buf mapping. This series should make accelerated desktop work on DG1 with DG1-enabled OpenGL. v2: - Address review comments by Matthew Auld on patch 1/5. More details on the patch commit message. - Address a dma-buf locking issue pointed out by Michael Ruhl, and add a selftest to catch that issue moving forward. - Rebase the dma-buf migration patch on the above-mentioned fix. v3: - Fix i915_gem_object_can_migrate() to return true if object is already in the correct region, even if the object ops doesn't have a migrate() callback. - Update typo in commit message. v4: - Ditch dma-buf patches for now. - Improve documentation (Suggested by Mattew Auld and Michael Ruhl) - Always assume TTM migration hits a TTM move and unsets the pages through move_notify. (Reported by Matthew Auld) - Add a dma_fence_might_wait() annotation to i915_gem_object_wait_migration() (Suggested by Daniel Vetter) - Selftest updates (See specifics on that patch). - Added R-Bs v5: - Re-add might_sleep() annotation to i915_gem_object_wait_migration() - Added R-B.
