Re: modesetting vs intel in 10.0

Am I correct that even with all the improvements, there are still
Intel video systems that aren't supported?  On a Dell Latitude 7420,
dmesg shows:

[     1.051227] pchb0 at pci0 dev 0 function 0: Intel Tiger Lake (UP3
4Core) Host (rev. 0x01)
[     1.051227] i915drmkms: preliminary hardware support disabled
[     1.051227] genfb0 at pci0 dev 2 function 0: Intel UHD Graphics
(GT2, 96/80 EU) (rev. 0x01)
[     1.051227] genfb0: framebuffer at 0x4000000000, size 1920x1080,
depth 32, stride 7680
[     1.051227] genfb0: shadow framebuffer enabled, size 8100 KB
[     1.051227] wsdisplay0 at genfb0 kbdmux 1: console (default, vt100
emulation), using wskbd0
[     1.051227] wsmux1: connecting to wsdisplay0
[     1.051227] drm at genfb0 not configured

and X is only working with wsfb.  I've been intending to look into
this myself, but $DAYJOB keeps getting in the way.  (I even downloaded
about 9000 pages of Intel documentation as a start.)  On the other
hand, if there's something I'm doing wrong and am just missing the
boat, I'd love to know.  TIA
