In earlier series, venus driver is switching the vcodec GDSC to HW control mode before disabling the GDSC by invoking vcodec_control_v4(..., false) in poweroff_coreid(). Due to this, the subsequent GDSC enable from venus driver is failing while polling for GDSC power ON status, since GDSC is under HW control mode and HW can keep the GDSC in disabled state. Now a check is added in poweroff_coreid() to avoid switching the GDSC to HW control mode before disabling the GDSC for Venus V6 variants that use this new API. Hence during the next GDSC enable, GDSC will be in SW mode and GDSC will powerup properly. Thanks, Jagadeesh > --- > bod >

Right so the intention is to have HW GDSC control during playback only - and then revert to SW control when no stream is active, right ? I tried your series on today's -next. Here is -next without your changes https://drive.google.com/file/d/1PFuLOlEp582rBQUvuwc9PNZUBxn1ioYf/view?usp=sharing and here is -next with your changes https://drive.google.com/file/d/1PHR4rZnWUH9Wp2B-itT5yCUXIMOMZrwM/view?usp=sharing The first time I tried that test the stopping/stuttering was worse. So yes the original crash was fixed but, this looks like a performance regression to me. Here's the tree I tested with. https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/linux-next-24-05-23-review?ref_type=heads --- bod

There is in the video capture three times that I count where the video halts briefly, I guess we need to vote or set an OPP so the firmware knows not to power-collapse quite so aggressively. We seem to be having some qualcomm-wide variance on perf/pwr usage on some odd boots.. Any chance you could try like 5 times and see if it was a fluke? Konrad

The second time, captured in the video is only noticeable because I was *looking* for this specific error i.e. I don't think I would have noticed the error on the second run, had I not seen the first run. I'll find some time to do 5x with and 5x without. --- bod
