It's first time to testing DP port on Baytrail. Please attach dmesg *always* with drm.debug=0xe module parameter. Thank you. Created attachment 94051 [details]
update dmesg with "drm.debug=0xe"
This bug still can be reproduce on latest -nightly(64fcdb139972db2663469d8799968260fb43a26d)
I think jinxian make a mistake here, the true behavior is that HDMI+DP can't all light up while loading BIOS step. Closing old verified. |
