[AMD Official Use Only] Hi Michel, After the system idle for a while, the screen will be off(blank out) and AMD GPU will be put into a very low power state(BACO) due to runpm. However, I found there will be still DRM IOCTLS(which I paste below) coming regularly. And those IOCTLS(especially those for AMDGPU) will wake and back our GPU into normal state. To me, that’s a little weird as the system was just left there for nothing. I do not know what and why these DRM IOCTLs come for. Per Alex, it seems “desktop environments poll for display updates at regular intervals”. Do you also think so? Or any other insights?
