on this specific 'dmabuf' topic: from my understanding of
https://docs.kernel.org/driver-api/dma-buf.html, and my previous
experience in https://bugzilla.mozilla.org/show_bug.cgi?id=1840272
(which got 'fixed' by adding some ifdefs in
https://hg.mozilla.org/integration/autoland/rev/15d494dac453),
proper 'dmabuf' support (whatever that is) requires eventfd.h, and some
kernel support. I dont think we have such thing in our drm support, and
*think* freebsd has some, but i haven't looked much there.
