I managed to get my whiskey lake GPU working

vgapci0 at pci0:0:2:0:     class=0x030000 card=0x08a51028 chip=0x3ea08086 rev=0x00 hdr=0x00
     vendor     = 'Intel Corporation'
     device     = 'UHD Graphics 620 (Whiskey Lake)'
     class      = display
     subclass   = VGA

I'm now running FreeBSD 12.0-RELEASE and using the drm-current-kmod.

Xorg log is here:

Multi-monitor works.

The only thing I have noticed is that when using ctrl-mousewheel to zoom in xfce4, the zooming is sluggish.

Much appreciation to the people working on X stuff for FreeBSD.

Best regards
