memkind_hugetlb - Man Page


memkind_hugetlb — hugetlb memory memkind operations.
Note: This is EXPERIMENTAL API. The functionality and the header file itself can be changed (including non-backward compatible changes) or removed.


int memkind_hugetlb_check_available_2mb(struct memkind *kind);
int memkind_hugetlb_get_mmap_flags(struct memkind *kind, int *flags);
void memkind_hugetlb_init_once(void);


The hugetlb memory memkind operations enable memory kinds which use the Linux hugetlbfs file system.  For more information about the hugetlbfs see link below.

memkind_hugetlb_check_available_2mb() check if there are 2MB pages reserved in the default hugetlbfs.  If the kind implements ops.get_mbind_nodemask(), then only the NUMA nodes set by the nodemask are checked, otherwise every NUMA node is checked.

memkind_hugetlb_get_mmap_flags() sets the flags for the mmap() system call such that the hugetlbfs is utilized for allocations.

memkind_hugetlb_init_once() this function initializes MEMKIND_HUGETLB kind and it should not be called more than once. Note: memkind_hugetlb_init_once() may reserve some extra memory.
