Hi,
Where can I find the Open Programmable Interrupt Controller (PIC)
Specification? Does anybody know the URL that I can get it? It seems that
the openpci@amd•com does not work now.
thanks in advance,
Haitao

I've just sent you a copy by personal email.

While not the openpic spec if you grab any of the Freescale RM for =
MPC85xx chips there will be a chapter on the PIC that is an "openPIC" =
based interrupt controller.

I ever searched openpic specification on google for several times, but
unfortunately nothing found.
Could anybody point me where I can get the openpic specification?
The source code seems being from IBM: arch/powerpc/sysdev/mpic.c
Thanks in advance,
Gavin

Thanks, Kumar. Actually, I'm facing a wired issue on my system: some times, the interrupt
from external devices can't be seen from CPU. That means the CPU was never disturbed by
extern interrupts at some point. I don't know why, it seems the PIC just ignored the
external interrupts.
We're using Pasemi 1682M part, which integrated a openpic compatible PIC. But the CPU part has 2
cores. There're 3 kinds of interrupts:
several internal interrupts - priority 8
one external interrupt - priority 8
IPI - priority 10
Thanks,
Gavin
