When I updated my stable/13 machine from source, from
March 16 to March 30, DRM was broken (did nothing).
Rebuilding graphics/drm-fbsd13-kmod fixed it.

So there was an ABI break in this time window.=C2=A0 This entry from
UPDATING implicates LinuxKPI changes as a likely candidate:

20220327:
=C2=A0 =C2=A0 =C2=A0 =C2=A0 Bump __FreeBSD_verion to 1301501 after merging = LinuxKPI and
=C2=A0 =C2=A0 =C2=A0 =C2=A0 net80211 changes in order to help out-of-tree c= onsumers to deal
=C2=A0 =C2=A0 =C2=A0 =C2=A0 accordingly.

Yes. So there was. https:/= /reviews.freebsd.org/D33915 should unbreak the KPI and give us wiggle r= oom in the future after 13.0 is no longer supported. That will restore the = KBI and we'll pretend that March 27 - April 2nd/3rd never happened (the= least bad of several bad alternatives).
