Information About FreeBSD Graphics: DRM-specific Notes

General

The way you need to manage your Direct Rendering Manager (DRM) bits depends on your OS update strategy.

In either case you will need to install the graphics/drm-kmod metaport. It should install the correct things for you for your OSVERSION as reported. See the table below for further explanation of what it will try to install.

Release Versions

• If you are running a release version of FreeBSD:

  • You can use pkg install to install the graphics/drm-kmod metaport.

  • You can use pkg upgrade to stay in sync.

STABLE or CURRENT Versions

• If you are instead running stable or current:

  • "When using stable (or current) it is important that the kernel and the drm-kmod modules are in sync." -- NiclasZeising, in PR 245923, 20200427. Therefore:

    • You will have to build and install the graphics/drm-kmod port manually, using the Ports Collection.

    • Whenever you rebuild the kernel, you will also need to rebuild and reinstall graphics/drm-kmod to stay in sync.
