Or, associate the interrupt with a file descriptor, while in userspace, utilize inotify to react when there is a change in file status? One I also heard about user space interrupt handling, but that requires separate kernel patches too (I believe it is described in LWN.net, please search there) Hope it helps. regards Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
