[PATCH] drm/amd/display: Allow dirty rects to be sent to dmub when abm is active

From: Josip Pavic
Date: Fri Feb 09 2024 - 16:05:18 EST


[WHY]
It's beneficial for ABM to know when new frame data are available.

[HOW]
Add new condition to allow dirty rects to be sent to DMUB when ABM is
active. ABM will use this as a signal that a new frame has arrived.
