https://bugzilla.kernel.org/show_bug.cgi?id=219556 Bug ID: 219556 Summary: AMDGPU monitoring is broken Product: Drivers Version: 2.5 Kernel Version: 6.13-rc1 Hardware: AMD OS: Linux Status: NEW Severity: normal Priority: P3 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: i.r.e.c.c.a.k.u.n+bugzilla.kernel.org@xxxxxxxxx Regression: Yes Bisected 831c1926ee728c3e747255f7c0f434762e8e863d commit-id: In 6.13-rc1, AMDGPU monitoring is broken. Many sysfs knobs simply output nothing. For example: # cd /sys/class/drm/card1/device # <gpu_busy_percent # <pp_dpm_sclk # <pp_od_clk_voltage # <hwmon/hwmon6/temp1_input Otherwise the kernel log seems to be totally fine and GPU itself appears to work normally. I tried AMD GPUs of different generations, so it doesn't appear to be series/model specific. I have done a bisection though. first bad commit: [831c1926ee728c3e747255f7c0f434762e8e863d] Merge tag 'uml-for-linus-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/uml/linux -- You may reply to this email to add a comment.
