CPU masks

CPU masks are used in sched_get_affinity()/sched_set_affinitity() functions
they contain set of cpuid's, on that thread is allowed to run.

cpuid is id of strand object taken from libhostinfo

Functions

cpumask_create

publicplat

Allocate and initialize new CPU mask

LIBEXPORT PLATAPI cpumask_t* cpumask_create()

cpumask_destroy

publicplat

Destroy CPU mask

LIBEXPORT PLATAPI void cpumask_destroy(cpumask_t* mask)

cpumask_reset

publicplat

Remove all CPUs from mask

LIBEXPORT PLATAPI void cpumask_reset(cpumask_t* mask)

cpumask_set

publicplat

Add CPU to mask

LIBEXPORT PLATAPI void cpumask_set(cpumask_t* mask, int cpuid)

cpumask_clear

publicplat

Remove CPU from mask

LIBEXPORT PLATAPI void cpumask_clear(cpumask_t* mask, int cpuid)

cpumask_isset

publicplat

Test to see if CPU is inside this mask

LIBEXPORT PLATAPI boolean_t cpumask_isset(cpumask_t* mask, int cpuid)

cpumask_count

publicplat

Returns count of CPUs in mask

LIBEXPORT PLATAPI int cpumask_count(cpumask_t* mask)

cpumask_eq

publicplat

Returns B_TRUE if masks a and b are equal

LIBEXPORT PLATAPI boolean_t cpumask_eq(cpumask_t* a, cpumask_t* b)

cpumask_contains

publicplat

Returns B_TRUE if b is submask of a

LIBEXPORT PLATAPI boolean_t cpumask_contains(cpumask_t* a, cpumask_t* b)

cpumask_or

publicplat

Returns new CPU mask that contains CPUs that are included in
both a and b masks (similiar to boolean or)

NOTES
Resulting mask should be freed with cpumask_destroy()

LIBEXPORT PLATAPI cpumask_t* cpumask_or(cpumask_t* a, cpumask_t* b)
