This feature is meant to unblock PSTATE for certain high end display configs on dcn315. This is achieved by allocating CRB to detile buffer based on display requirements to meet pstate latency hiding needs. Tested-by:

- Due to hardware related QoS issues, we need to limit certain SKUs with less memory channels to DPM1 and above. - At DPM0 + workload running, the urgent return latency can exceed 15us (the expected maximum is 4us) which results in underflow Cc: stable@vger.kernel.org Tested-by:

Currently, on a handful of ASICs. We allow the framebuffer for a given plane to exist in either VRAM or GTT. However, if the plane's new framebuffer is in a different memory domain than it's previous framebuffer, flipping between them can cause the screen to flicker. So, to fix this, don't perform an immediate flip in the aforementioned case. Cc: stable@vger.kernel.org Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2354Reviewed-by:

[Why] The bit for flip addr is being set causing the determination for FAST vs MEDIUM to always return MEDIUM when plane info is provided as a surface update. This causes extreme stuttering for the typical atomic update path on Linux. [How] Don't use update_flags->raw for determining FAST vs MEDIUM. It's too fragile to changes like this. Explicitly specify the update type per update flag instead. It's not as clever as checking the bits itself but at least it's correct.
