Not a real programmer but....
I wonder if adding the following (taken from
shutdown_reset lines in kern_shutdown.c)
DELAY(1000000);
cpu_reset();
to the following in the cpu_halt(); area would work.
You would have to modify the delay time.
/*
* If the shutdown was a clean halt, behave
accordingly.
*/
static void
shutdown_halt(void *junk, int howto)
{
if (howto & RB_HALT) {
printf("\n");
printf("The operating system has halted.\n");
printf("Please press any key to reboot.\n\n");
switch (cngetc()) {
case -1: /* No console, just die */
cpu_halt();
/* NOTREACHED */
default:
howto &= ~RB_HALT;
break;
}
}
}
