Revision 0abfe7e2570d7c729a7662e82c09a23f00f29346 authored by Chris Wilson on 22 March 2017, 20:59:30 UTC, committed by Jani Nikula on 27 March 2017, 08:56:27 UTC
Commit e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc") converted the legacy intel_ringbuffer submission to the same context pinning mechanism as execlists - that is to pin the context until the subsequent request is retired. Previously it used the vma retirement of the context object to keep itself pinned until the next request (after i915_vma_move_to_active()). In the conversion, I missed that the vma retirement was also responsible for marking the object as dirty. Mark the context object as dirty when pinning (equivalent to execlists) which ensures that if the context is swapped out due to mempressure or suspend/hibernation, when it is loaded back in it does so with the previous state (and not all zero).
