2018-09-20drm/i915/guc: Restore preempt-context across S3/S4Chris Wilson
Stolen memory is lost across S4 (hibernate) or S3-RST as it is a portion of ordinary volatile RAM. As we allocate our rings from stolen, this may include the rings used for our preempt context and their breadcrumb instructions. In order to allow preemption following hibernation and loss of stolen memory, we therefore need to repopulate the instructions inside the lost ring upon resume. To handle both module load and resume, we simply defer constructing the ring to first use.
