HugePages_Total: xxx HugePages_Free: yyy -Hugepagesize: zzz KB +HugePages_Rsvd: www +Hugepagesize: zzz kB + +where: +HugePages_Total is the size of the pool of hugepages. +HugePages_Free is the number of hugepages in the pool that are not yet +allocated. +HugePages_Rsvd is short for "reserved," and is the number of hugepages +for which a commitment to allocate from the pool has been made, but no +allocation has yet been made. It's vaguely analogous to overcommit. /proc/filesystems should also show a filesystem of type "hugetlbfs" configured in the kernel. |
