Subject: RFC: Add write flag to reservation object fences
Date: Thu, 9 Aug 2018 13:37:07 +0200 [thread overview]
Message-ID: <20180809113713.48024-1-christian.koenig@amd.com> (raw)
Hi everyone,
This set of patches tries to improve read after write hazard handling for reservation objects.
It allows us to specify for each shared fence if it represents a write operation.
Based on this the i915 driver is modified to always wait for all writes before pageflip and the previously used workaround is removed from amdgpu.
Please comment,
Christian.
