Hello, Following is the output of cat /proc/interrupts

200: 9634 0 0 PCIe0-MSI eth0
I want to change the processor affinity of the above PCIe interrupt
By executing command echo 2 > /proc/irq/200/smp_affinity I get the following error
sh: write error: Input/output error
Even after changing the file permissions I have the same problem.
AFAIK, even if you change that file's permission, actually it stays the same. So you need to switch into root or use sudo to change the affinity -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
