This patchset implements synchronous accelerated migration and clearing for i915 on TTM. We plan to follow up with these operations made asynchronous to the extent of TTM support for that: A couple of patches from Chris which implement pipelined migration and clears by atomically writing the PTEs in place before performing the actual blit. Some ww utilities mainly for the accompanying selftests added by Thomas, as well as modified the above patches for ww locking- and lmem support. Hooked up to our TTM backend by Ramalingam Finally, on request from Daniel, we ditch old blit code which is now obsolete. v2: - A couple of minor style fixes pointed out by Matthew Auld - Export and use intel_engine_destroy_pinned_context() to address a CI warning / failure. v3: - Acceleration hooked up to TTM - Minor fixes to review comments (Pointed out by Matthew Auld) - Fix pipelined blit handling of engine instances (Pointed out by Matthew Auld) - Ditch old blit code, (Pointed out by Daniel) v4: - Rescue a selftest that was removed with the old blit code (Pointed out by Matthew Auld) - Extended gpu waits in the TTM accel move function (Pointed out by Thomas Hellström) v5: - Minor rebase on buddy series. - Added R-Bs for the last patches.
