unable to set smp_affinity of PCIe interrupt

[Amit Mahadik]

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

           CPU0       CPU1       CPU2

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.

I would like to know how to change the affinity of the above virtual interrupt??

Regards,
Amit.
