[Why] When we transfer the WM range table to SMU, they can perform a watermark switch right away. This can be a problem if we're in not in accelerated mode during hw_init as SMU may initiate a dummy p-state change before the rest of the watermarks are programmed. Watermark set A is defined to be sufficient for all cases, so we can copy the values from set A to all other sets, avoiding any issues from SMU doing WM switches. [How] - new hubbub func init_watermarks - copy register values from set A to all other sets - call init_watermarks before calling notify_wm_ranges Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Eryk Brol <eryk.brol@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
