Subject: [Intel-gfx] [PATCH 01/10] drm/i915/gt: Do not suspend bonded requests if one hangs
Date: Wed, 20 Jan 2021 12:21:56 +0000 [thread overview]
Message-ID: <20210120122205.2808-1-chris@chris-wilson.co.uk> (raw)
Treat the dependency between bonded requests as weak and leave the
remainder of the pair on the GPU if one hangs.
