NAME¶
irq_force_affinity - Force the irq affinity of a given irq
SYNOPSIS¶
int irq_force_affinity(unsigned int irq, const struct cpumask * cpumask);
ARGUMENTS¶
unsigned int irq
Interrupt to set affinity
const struct cpumask * cpumask
cpumask
DESCRIPTION¶
Same as irq_set_affinity, but without checking the mask against online cpus.
Solely for low level cpu hotplug code, where we need to make per cpu interrupts affine before the cpu becomes online.
