    Kernel Device Driver signalling the User....

    I want the device driver to issue a signal to the user. The user should have a signal handler. The signal must be sent from device driver interrupt sub-routine. The interrupt source in the kernel can be anything - basically any peripheral interrupt.

    Can someone point me a link to get some sample code? I am not sure how to do the above.
