https://bugzilla.kernel.org/show_bug.cgi?id=216814 Bug ID: 216814 Summary: amdgpu: CTM support has disappeared (vega) Product: Drivers Version: 2.5 Kernel Version: 6.0 Hardware: AMD OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: maxijac@xxxxxxx Regression: No Hello, I noticed the CTM support from X is no longer advertised with recent kernels. Card: Vega64 xf86-video-amdgpu: 22.0.0-1 With older kernels, xrandr reports CTM correctly. With the same X stack, simple rebooting on a more recent kernel, CTM is not advertised anymore. >$ uname -r >5.15.83-1-lts >$ xrandr --prop | grep -i ctm > CTM: 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 > CTM: 0 > CTM: 0 > CTM: 0 > CTM: 0 > CTM: 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 >$ > > -- Reboot to 6.1 -- > >$ uname -r >6.1.0-arch1-1 >$ xrandr --prop | grep -i ctm >$ I also have a custom config 6.0 kernel that shows no CTM so the break has happened between 5.15 and 6.0. I tried looking at commits in between and code changes in amdgpu but did not notice anything obvious. -- You may reply to this email to add a comment.
