KTHREAD_BIND(9) Driver Basics KTHREAD_BIND(9)NAME
kthread_bind - bind a just-created kthread to a cpu.
void kthread_bind(struct task_struct * p, unsigned int cpu);
thread created by kthread_create.

This function is equivalent to set_cpus_allowed, except that cpu doesn't need to be online, and the thread must be stopped (i.e., just
returned from kthread_create).

CPUSET(3) BSD Library Functions Manual CPUSET(3)NAME
cpuset_create, cpuset_destroy, cpuset_zero, cpuset_set, cpuset_clr, cpuset_isset, cpuset_size -- dynamic CPU sets
cpuset_set(cpuid_t cpu, cpuset_t *set);
cpuset_clr(cpuid_t cpu, cpuset_t *set);
cpuset_isset(cpuid_t cpu, const cpuset_t *set);
cpuset_size(const cpuset_t *set);
This section describes the functions used to create, set, use and destroy the dynamic CPU sets.
This API can be used with the POSIX threads, see pthread(3) and affinity(3).
The ID of the primary CPU in the system is 0.
Allocates and initializes a clean CPU-set. Returns the pointer to the CPU-set, or NULL on failure.
Destroy the CPU-set specified by set.
Makes the CPU-set specified by set clean, that is, memory is initialized to zero bytes, and none of the CPUs set.
Sets the CPU specified by cpu in set. Returns zero on success, and -1 if cpu is invalid.
Clears the CPU specified by cpu in the CPU-set set. Returns zero on success, and -1 if cpu is invalid.
Checks if CPU specified by cpu is set in the CPU-set set. Returns the positive number if set, zero if not set, and -1 if cpu is
Returns the size in bytes of CPU-set specified by set.

The dynamic CPU sets appeared in NetBSD 5.0.
