[Intel-gfx] [CI 1/2] drm/i915: Apply i915_request_skip() on submission

[Intel-gfx] [CI 1/2] drm/i915: Apply i915_request_skip() on submission

[Chris Wilson]

Trying to use i915_request_skip() prior to i915_request_add() causes us
to try and fill the ring upto request->postfix, which has not yet been
set, and so may cause us to memset() past the end of the ring.

Instead of skipping the request immediately, just flag the error on the
request (only accepting the first fatal error we see) and then clear the
request upon submission.

[Intel-gfx] [CI 2/2] drm/i915/gt: Propagate change in error status to children on unhold

[Chris Wilson]

As we release the head requests back into the queue, propagate any
change in error status that may have occurred while the requests were
temporarily suspended.
