Hi As with recent 13-CURRENT, we're pushing some updates that might break build of drm modules temporarily on 12-STABLE. One of those changes is moving lindebugfs.ko from ports to base. If you're building your kernel with MODULES_OVERRIDE, don't forget to include it since it is required by drm drivers that use linuxkpi. A new drm-fbsd12.1-kmod port for 12-STABLE (later includes also 12.1-RELEASE) will be created. The goal is to provide support for hardware that is supported by Linux 5.0, in FreeBSD 12.1. In an emergency, drivers for 12-STABLE can (hopefully) be built directly from github here https://github.com/FreeBSDDesktop/kms-drm (drm-v4.16 or drm-v5.0 branches), once today's series of commits are in. Any testing on 12-STABLE is welcome. drm-v5.0 is still WIP but should be quite usable. Cheers!
