Title:
HDMI cause display malfunctioning on BMG hardware
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Oracular:
Fix Committed
Bug description:
[ Impact ]
* There are 4 ports on the BMG (3 DP and 1 HDMI). Display for those 3
DP ports are working fine, including single and double monitor
display. However, whenever the HDMI port is used, after that, the 3 DP
ports will not be working. Meanwhile, the HDMI port is still working.
[ Fix ]
* Upstream fix:
drm/xe: Remove runtime argument from display s/r functions
drm/xe/display: Separate the d3cold and non-d3cold runtime PM handling
drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM
resume
drm/xe: Fix missing conversion to xe_display_pm_runtime_resume
[ Test Plan ]
1. Plug in HDMI
2. Plug out HDMI
3. Plug in DP
This is already tested/verified on oracular:linux-intel which includes
those fixes.
[ Where problems could occur ]
* BMG specific regression
[ Other Info ]
* Fix pointed out by intel engineer. Backport done by them, just
checked/modified it to follow the SRU process.
