    OpenBSD has drm nodes and obviously DMA buffers. The bloq post is talking about a particular Linux feature of DRM nodes that allow users with CAP_SYS_ROOT/ADMIN to become a "drmMaster".
    Read it again. They have DRM CARD nodes and lack RENDER nodes - they omitted the "behave like drmMaster even if not root" behavior. Necessary code for DMA-Buf is commented out at this point, just grep around for #ifdef __linux__ parts in the imported drm code. You don't need to go further than:

    src/sys/dev/pci/drm/drm_drv.c at master · openbsd/src
    https://github.com/openbsd/src/blob/master/sys/dev/pci/drm/drm_drv.c#L210
    Read-only git conversion of OpenBSD's official CVS src repository. Pull requests not accepted - send diffs to the tech@ mailing list. - openbsd/src
