Revision 5b2e31201c268c2331a209af799d667619216d40 authored by Chris Wilson on 07 December 2018, 13:40:37 UTC, committed by Joonas Lahtinen on 12 December 2018, 10:27:44 UTC
Adding an extra MI_STORE_DWORD_IMM to the gpu relocation path for gen3 was good, but still not good enough. To survive 24+ hours under test we needed to perform not one, not two but three extra store-dw. Doing so for each GPU relocation was a little unsightly and since we need to worry about userspace hitting the same issues, we should apply the dummy store-dw into the EMIT_FLUSH.
