John Baldwin 992029ba10 Reliably enable debug exceptions on all CPUs. ... Previously, debug exceptions were only enabled on the boot CPU if DDB was enabled in the dbg_monitor_init() function. APs also called this function, but since mp_machdep.c doesn't include opt_ddb.h, the APs ended up calling an empty stub defined in <machine/debug_monitor.h> instead of the real function. Also, if DDB was not enabled in the kernel, the boot CPU would not enable debug exceptions. Fix this by adding a new dbg_init() function that always clears the OS lock to enable debug exceptions which the boot CPU and the APs call. This function also calls dbg_monitor_init() to enable hardware breakpoints from DDB on all CPUs if DDB is enabled. Eventually base support for hardware breakpoints/watchpoints will need to move out of the DDB-only debug_monitor.c for use by userland debuggers.
