I re-enabled PSR and booted into the 5.11 kernel. I see: => sudo cat /sys/kernel/debug/dri/0/i915_edp_psr_status Sink support: yes [0x03] PSR mode: PSR2 enabled Source PSR ctl: enabled [0xc2044a99] Source PSR status: SLEEP [0x30000111] Busy frontbuffer bits: 0x00000000 Frame: PSR2 SU blocks: 0 0 1 0 2 0 3 0 4 0 5 0 6 0 7 0 PSR2 selective fetch: disabled
The value for PSR status varies between SLEEP, DEEP_SLEEP, CAPTURE, and IDLE. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947326 Title: [Dell Latitude 7320] Clipping and pointer lag after update to kernel 5.13 (fixed by i915.enable_psr=0) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1947326/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
