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
