Hi, all.
I found info that IO APIC limit the number of cpu cores for
interrupt handling to 8(because of just 4 bits using for cpu number
or something like this). But now MSI/MSI-X is used for interrupts
and i don't know is this limit is actual now.
For example, i have 4 nic with 8 rx/tx queues each and 32 cpu cores.
Can i scale nic interrupt handling to all this cores with smp_affinity?
Thanks.
