Subject: unable to set smp_affinity of PCIe interrupt
Date: Wed, 8 May 2013 05:05:09 -0700 (PDT)	[thread overview]
Message-ID: <1368014709.52476.YahooMailNeo@web125704.mail.ne1.yahoo.com> (raw)

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.
