commit 821ed7df6e2a1dbae243caebcfe21a0a4329fca0 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Sep 9 14:11:53 2016 +0100 drm/i915: Update reset path to fix incomplete requests Update reset path in preparation for engine reset which requires identification of incomplete requests and associated context and fixing their state so that engine can resume correctly after reset. The request that caused the hang will be skipped and head is reset to the start of breadcrumb. This allows us to resume from where we left-off. Since this request didn't complete normally we also need to cleanup elsp queue manually. This is vital if we employ nonblocking request submission where we may have a web of dependencies upon the hung request and so advancing the seqno manually is no longer trivial.
