Hi,
I tried to change value in interface interrupt's smp_afinity value
as per my understanding , smp_afinity values
1 for cpu0
2 for cpu1
4 for cpu2
8 for cpu3
that way cpu0+cpu1 = 1 + 2 = 3
so i set different values for test .but each time it only binds with
single cpu from cpu0 / cpu1 / cpu2 or cpu3.
i also start cpuspeed service and irqbalance --oneshot.
But same result.i am not able to use more than 1 cpu for single interface.
Regards,
Benjo
