Is there any reason that a Critical Input Interrupt will not work reliably
on a 44x powerpc?
I am using an AMCC now Applied Micro AMCC460EX
and changed
CRITICAL_EXCEPTION(0x0100, CriticalInput, unknown_exception)
to
CRITICAL_EXCEPTION(0x0100, CriticalInput, do_MyCritIntr)
The code for the handler is trivial
ie.
int crintrcount;
void do_MyCritIntr(void)
{
crintrcount++;
}
The code runs for a while but eventually I get panic messages and the
system hangs. Is there something I must alter in the kernel to do this
reliably?
