SVN rev 202763 on 2010-01-21 17:55:47Z by jhb
MFC 198134,198149,198170,198171,198391,200948:
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().
