We observe black lines (underflow) on display when playing a 4K video with UVD. On Disabling Low memory P state this issue is not seen. In this patch ,disabling low memory P state only when video size >= 4k. Multiple runs of power measurement shows no impact Signed-off-by: suresh guttula <suresh.guttula@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
