--- Comment #28 from Alexandre Demers alexandre.f.demers@gmail.com --- Alex, a simple question: you said bit 0 in EVERGREEN_CRTC_CONTROL stops the CRTC sync. With the culprit commit, when is it set? I mean, I had a quick look in the driver's code and I couldn't find it. When going in suspend state, shouldn't it be set to 0? Then, on resume, shouldn't it be set to 1? I may just have missed it, but could this be something missing? Same questions goes for GPU soft reset.
Before the culprit commit, we were setting bit 0 to 0 on stop and setting it back to 1 on resume, which was working great. Why aren't we doing it anymore when suspending and resuming?
