Noticed a regression with VRR after updating the kernel. My main monitor's VRR stopped being recognized, I was no longer able to enable it in my desktop environment settings and /sys/kernel/debug/dri/0/DP-1/vrr_range showed a range of 0 to 0. I did a bisect on the linux kernel git tree, and found that the commit introducing this issue is 0159f88a99c9f5722dbe52ac42faf3446f371dea. The monitor is connected via DisplayPort, no converters as far as I know. The GPU in use is AMD Radeon RX 6700XT. There is another monitor, connected over HDMI and it has VRR working in all the versions I've tested. Attached the DisplayPort monitor's edid copied from sysfs. #regzbot introduced: 0159f88a99c9f5722dbe52ac42faf3446f371dea
Can you please share your bisect log? There was a regression from that commit but it was already fixed a long time back.
