CPUPRI_FIND(9) Driver Basics CPUPRI_FIND(9)
NAME
cpupri_find - find the best (lowest-pri) CPU in the system
SYNOPSIS
int cpupri_find(struct cpupri * cp, struct task_struct * p, struct cpumask * lowest_mask);
ARGUMENTS
cp
The cpupri context
p
The task
lowest_mask
A mask to fill in with selected CPUs (or NULL)
NOTE
This function returns the recommended CPUs as calculated during the current invocation. By the time the call returns, the CPUs may have in
fact changed priorities any number of times. While not ideal, it is not an issue of correctness since the normal rebalancer logic will
correct any discrepancies created by racing against the uncertainty of the current priority configuration.
RETURN
(int)bool - CPUs were found
