The fix adds waiting for shaders and flushing the L2 cache after every submission on these older GPUs to prevent VM faults and GPU hangs caused by EVENT_WRITE_EOP signaling fences while L2 is still dirty. Additionally, a prior RADV workaround for Hawaii GPUs has been reverted since an equivalent fix was upstreamed to the AMDGPU kernel driver, which had been causing performance regressions on Hawaii hardware. ## Full article daily.dev links to this article rather than hosting it.
