Thanks everyone for the information. I am trying to implement a software callable interrupt so it can be called by user-mode code to indicate that certain events have occurred (it's part of an instrumentation package I'm working on). I don't want to add a syscall since there is other code on the system that is already monitoring int 0x80, and I don't want these instrumentation interrupts to be visible by the code already monitoring syscalls. Unless someone has a more specific suggestion, I will look into request_irq(). However, it appears that will require creation of a new device (so I can pass the devname and dev_id params), which I'd rather not do, since I'd rather that the instrumentation impacts/changes the system as little as possible. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
