Don't know why you want to handle it from user space, but the easiest way to notify an application would be to send a signal. Have a special ioctl() to notify the driver that this application wants a signal, and then when the driver receives the interrupt it clears the condition and sends a signal to the registered application(s). -Bret -- Bret Indrelee QLogic Corporation Bret.Indrelee at qlogic.com 6321 Bury Drive, St 13, Eden Prairie, MN 55346 ** Sent via the linuxppc-embedded mail list.
