Since the series is fairly large, I can rebase it and send it to you if you'd prefer?

I had a look this morning, but couldn't reproduce it here > I didn't see this on my monitor when switching into/out of standby. > I didn't see when switching...

The only case where this could happen is if one of the functions in vc4_hdmi_encoder_pre_crtc_configure that can error (clk_set_rate, clk_set_min_rate, clk_prepare_enable or pm_runtime_resume_and_get) does return an error. Can you print...

Another thing I just remembered, we don't use the hotplug interrupts on the 3B and the polling interval is 10s so plugging/unplugging the monitor fairly fast might be ignored and...

I'm a bit puzzled by this bug. I did more testing today and neither my 3B or 3B+ shows it on any of the three monitors I tested it with....

I've done that for about 45 minutes now on a 3B, with and without X running, and making sure the kernel would detect the monitor status properly. I'm still not...

The first one is wow, that bug report is awesome, thanks! About the issue itself, yes, the analysis is accurate. It's been a while and it's fairly complex, so my...

I think it should work. In such a case, the core will wait for all CRTCs vblank in the commit https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/vc4/vc4_kms.c#L412 https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/drm_atomic_helper.c#L1562 Chances are the vsync will be synchronized, or...

I wonder if it's a similar issue to #4571. Does it occur only when playing a video or rendering on the GPU, or does it also stall the rest of...

I've been trying to reproduce it this afternoon and can't really see any meaningful difference with and without that patch applied. glxgears will stall for a couple of frames from...
