HW context lost under mempressure, fixed circa 4.9. Definitely fixed as of commit 5d4bac5503fcc67dd7999571e243cee49371aef7 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Mar 22 20:59:30 2017 +0000 drm/i915: Restore marking context objects as dirty on pinning 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). which is v4.12. |
