I looked at this, and can say it is not an easy thing to implement. The system call is trivial to do in qemu, but the problem is that we have to catch reads from the file descriptor returned, and convert signalfd_siginfo structure between host and target. That's probably why it hasn't been implemented so far. Hwell... /mjt
