Author: Samuel Pitoiset <[email protected]> Date: Thu Jan 25 15:46:50 2018 +0100 radv: fix a GPU hang with RADV_DEBUG=syncshaders The GPU hangs when the driver forces a PS_PARTIAL_FLUSH after a dispatch call (and vice versa for graphics). Something has changed in the kernel driver because it used to work.
