Functions

func UpdateIRQSmpAffinityMask

func UpdateIRQSmpAffinityMask(cpus, current string, set bool) (cpuMask, bannedCPUMask string, err error)

UpdateIRQSmpAffinityMask take input cpus that need to change irq affinity mask and the current mask string, return an update mask string and inverted mask, with those cpus enabled or disable in the mask.
