/proc/interrupts

Altera_Forum · ‎01-12-2005

Why do I get repeated outputs from "cat /proc/interrupts" instead of just one? Has anyone else experienced this problem? What about the spurious interrupt? Has this been seen by anyone else?

I have a Microtronix uKit board.

The repeating display is a bug in the Nios II port. It has no other side-effects other than repeating 32 times.

OK, thanks for the info.

Is the spurios interrupt also a known software bug, or could this indicate a problem with the hardware/fpga design?

the "spurious" entry shows how many spurious interrupts have happened. It is a normal feature (and in your system there is 0 spurious interrupt, which is good).

One thing I am not sure is in your system there are more than 1 interrupts registered under the name of eth0. Do you really have 4 ethernet devices? If yes, it is better name them differently.
