(v2) X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82ba384c10d598bee4786ef5f79e92a0e7b53892;p=mesa.git radv: force cs/ps/l2 flush at end of command stream. (v2) This seems like a workaround, but we don't see the bug on CIK/VI. On SI with the dEQP-VK.memory.pipeline_barrier.host_read_transfer_dst.* tests, when one tests complete, the first flush at the start of the next test causes a VM fault as we've destroyed the VM, but we end up flushing the compute shader then, and it must still be in the process of doing something. Could also be a kernel difference between SI and CIK. v2: hit this with a bigger hammer. This fixes a bunch of hangs in the vk cts with the robustness tests.
