I have kept yours CPUs affinity with reply queues logic as it is. This
patch doesn't break any of it's original CPUs affinity with reply
queues calculation even when nr_cpus > the number of reply queues.
since below loop will help us to calculate CPU groups which needs to
affinity to particular reply queue when nr_cpus > the number of reply
queues
for (i = 0 ; i < group ; i++) {
ioc->cpu_msix_table[cpu] = index;
+ cpumask_or(reply_q->affinity_hint,
+ reply_q->affinity_hint, get_cpu_mask(cpu));
cpu = cpumask_next(cpu, cpu_online_mask);
}
I am iterating over the queues to get the MSIX vector number easily,
while calling irq_set_affinity_hint() API for setting CPUs affinity
hint for that MSIX vector.
