Subject: drm/amd/display: Cursor lag with PSR1 eDP
Git-commit: 4e65878de0db0a2f6778b78e10fd3b71eda4e4a5
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[Why]
On edp with psr1, we do not provide updates
of the cursor position regularly to firmware
like with PSR2. To send updates regularly,
the flag enable_sw_cntl_psr has to equal 1,
but cursor update should be provided
regularly to FW regardless of that flag.
[How]
Ensure that we always send cursor updates to
firmware when PSR version equals 1.
