Module name: src
Changes by: ketteniscvs.openbsd.org 2008/12/14 10:10:44

Modified files:
        sys/arch/sparc64/sparc64: db_interface.c
        sys/arch/sparc64/include: db_machdep.h
        sys/arch/sparc64/dev: bbc.c

Log message:
Implement a "machine xir" ddb command, making it possible to send an
External Initiated Reset (XIR) to processors. A XIR is non-maskable and will
drop us at the PROM ok prompt. This makes it possible to diagnose problems
where a CPU is spinning with interrupts disabled.

For now, this is only supported on machines with bbc(4).
