Re: DRM IOCTLS come regularly(every minute) still even after screen off

    Good morning,

    
    for the background I advised to contact you Michel since we couldn't
    find an explanation.

    
    Alex explanation might be correct, but the CS seems to come from the
    X server and is always roughly 60 seconds after going into power
    save.

    
    Any idea what that could be?

    
    Thanks,

    Christian.

        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?
