Bug 236933: graphics/libdrm: drmGetNodeTypeFromFd always fails
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236933



--- Description ---
For libva DRM backend to reliably support headless transcoding I need a way to
check if the opened device is a render node. drmGetNodeTypeFromFd() ==
DRM_NODE_RENDER appears to be the correct way but it doesn't work on FreeBSD.

$ pkg install libdrm pkgconf
$ cc test.c -o test $(pkg-config --cflags --libs libdrm)
$ ./test
unknown (-1) node
