Add a facility for associating optional descriptions with active interrupt handlers. This is primarily intended as a way to allow devices that use multiple interrupts (e.g. MSI) to meaningfully distinguish the various interrupt handlers. - Add a new BUS_DESCRIBE_INTR() method to the bus interface to associate a description with an active interrupt handler setup by BUS_SETUP_INTR. It has a default method (bus_generic_describe_intr()) which simply passes the request up to the parent device. - Add a bus_describe_intr() wrapper around BUS_DESCRIBE_INTR() that supports printf(9) style formatting using var args. - Reserve MAXCOMLEN bytes in the intr_handler structure to hold the name of an interrupt handler and copy the name passed to intr_event_add_handler() into that buffer instead of just saving the pointer to the name. - Add a new intr_event_describe_handler() which appends a description string to an interrupt handler's name. - Implement support for interrupt descriptions on amd64, i386, and sparc64 by having the nexus(4) driver supply a custom bus_describe_intr method that invokes a new intr_describe() MD routine which in turn looks up the associated interrupt event and invokes intr_event_describe_handler(). |
