Intel Skull Canyon NUC6i7KYK connected to HDMI2.0 monitor doesn't seem to find the display. The DP-to-HDMI2.0 LSPCon chip is Parade.

Can we have the dmesg logs please ? - Shashank
This is i915_display_info and attached dmesg bootlog from recent DRM-Tip debug kernel with HDMI2.0 monitor attached to Skull NUC HDMI port. It's different from earlier experience; I haven't bisected yet what has changed. I'll leave fi-skl-6770hq like this and see what information the fast-feedback and full runs bring forward. root@skl-6770hq:~# cat /sys/kernel/debug/dri/0/i915_display_info CRTC info --------- CRTC 41:

Shashank, any updates on this issue?
Tomi, is this issue occurs every time when Intel Skull Canyon NUC6i7KYK connected to monitor?
Yes, this issue was 100% reproducible. I haven't tried manually with recent kernels, so I can't tell if behaviour has changed from before. At least one Skull Canyon LSPcon fix by vsyrjala is in.
@Tomi, Can you verify this issue with latest drmtip and give the feedback?
Tomi, have you had any time for this. Perhaps I can give system to Lakshmi to try?
