Hello, Misc; I've been playing around with the kqueue(2) syscall and have a question about the EVFILT_DEVICE filter; what does the the descriptor in the identifier refer to? I've tried opening device files in /dev/ however upon invoking kqueue it returns immediately with 0 in fflgas.
I noticed in the release notes for 6.3 that it was added to make drm(4) work, so I'm not sure whether or not it's limited to that particular driver, or if I can use it with any other device; has anyone worked with EVFILT_DEVICE filter and have they gotten it to work for other devices? Thank you in advance. Ben Raskin
