Function affinity_mask 

Source 
pub fn affinity_mask(cpu: usize) -> String
Expand description

The /proc/irq/<n>/smp_affinity mask that names exactly cpu: comma-separated 32-bit hex words, most significant first.

scripts/tune-nic.sh writes the same format, so a worker’s log line and the IRQ it should be fed by can be compared by eye.

assert_eq!(compio_pool::cpu::affinity_mask(3), "00000008");
assert_eq!(compio_pool::cpu::affinity_mask(35), "00000008,00000000");
