Hello,
I just inserted in my student mini pc
OpenBSD 7.2
a brand new DP(male) to HDMI(female) adapter:
https://amazon.it/dp/B08GFJF7LP/
The adapter runs well as I'm able to interact with the station.
But just before the disk initialization some DRM message are reported
as diplayed below.
The tail of the dmesg says this:
drm:pid0:drm_dp_dual_mode_detect *ERROR* [drm] *ERROR* Unexpected DP
dual mode adaptor ID 20
inteldrm0: 1920x1080, 32bpp
wsdisplay0 at inteldrm0 mux 1: console (std, vt100 emulation), using
wskbd0
wskbd1: connecting to wsdisplay0
wsdisplay0: screen 1-5 added (std, vt100 emulation)
drm:pid901:drm_dp_dual_mode_detect *ERROR* [drm] *ERROR* Unexpected DP
dual mode adaptor ID 20
drm:pid65608:drm_dp_dual_mode_detect *ERROR* [drm] *ERROR* Unexpected DP
dual mode adaptor ID 20
drm:pid65608:drm_dp_dual_mode_detect *ERROR* [drm] *ERROR* Unexpected DP
dual mode adaptor ID 20
drm:pid65608:drm_dp_dual_mode_detect *ERROR* [drm] *ERROR* Unexpected DP
dual mode adaptor ID 20
Hope it is just fine to work around the prb.
