Thanks. Updating says:

A metaport, graphics/drm-kmod, was introduced for users of both the LinuxKPI-
based DRM components as well as the legacy ones. It is recommended to use the
metaport from now on, which will select a recommended DRM version based on
the FreeBSD version.
Attempting to build it on my 11.2 says:
===>>> This port is marked IGNORE
===>>> requires kernel source files in /usr/src
But one needs to read Makefile to see what, if anything, is actually required.
11.2 is marked IGNORE, although it specifies
RUN_DEPENDS= ${KMODDIR}/drm.ko:graphics/drm-stable-kmod
I do not have drm-stable-kmod installed, nor gpu-firmware-kmod on which
drm-stable-kmod depends. Given the RUN_DEPENDS, it seems like the IGNORE
might be a bug.

scanning pkg-plist in all ports comes up empty for amdgpu_dri
