If anyone has any objections, please let me know. ------------------ From: Tim Huang commit 36e7ff5c13cb15cb7b06c76d42bb76cbf6b7ea75 upstream. Use a proper MEID to make sure the CP_HQD_* and CP_GFX_HQD_* registers can be touched when initialize the compute and gfx mqd in mes_self_test. Otherwise, we expect no response from CP and an GRBM eventual timeout.
