Peter Antoine 364aece01a drm/i915: Avoid GPU hang when coming out of s3 or s4 ... This patch fixes a timing issue that causes a GPU hang when the system comes out of power saving. During pm_resume, We are submitting batchbuffers before enabling Interrupts this is causing us to miss the context switch interrupt, and in consequence intel_execlists_handle_ctx_events is not triggered. This patch is based on a patch from Deepak S <deepak.s@intel.com> from another platform. The patch fixes an issue introduced by: commit e7778be1ea drm/i915: Fix startup failure in LRC mode after recent init changes The above patch added a call to init_context() to fix an issue introduced by a previous patch. But, it then opened up a small timing window for the batches being added by the init_context (basically setting up the context) to complete before the interrupts have been turned on, thus hanging the GPU.
