[−][src]Enum nix::sys::mman::MmapAdvise
Usage information for a range of memory to allow for performance optimizations by the kernel.
Used by madvise
.
Variants
MADV_NORMAL
No further special treatment. This is the default.
MADV_RANDOM
Expect random page references.
MADV_SEQUENTIAL
Expect sequential page references.
MADV_WILLNEED
Expect access in the near future.
MADV_DONTNEED
Do not expect access in the near future.
MADV_REMOVE
Free up a given range of pages and its associated backing store.
MADV_DONTFORK
Do not make pages in this range available to the child after a fork(2)
.
MADV_DOFORK
Undo the effect of MADV_DONTFORK
.
MADV_HWPOISON
Poison the given pages.
Subsequent references to those pages are treated like hardware memory corruption.
MADV_MERGEABLE
Enable Kernel Samepage Merging (KSM) for the given pages.
MADV_UNMERGEABLE
Undo the effect of MADV_MERGEABLE
MADV_SOFT_OFFLINE
Preserve the memory of each page but offline the original page.
MADV_HUGEPAGE
Enable Transparent Huge Pages (THP) for pages in the given range.
MADV_NOHUGEPAGE
Undo the effect of MADV_HUGEPAGE
.
MADV_DONTDUMP
Exclude the given range from a core dump.
MADV_DODUMP
Undo the effect of an earlier MADV_DONTDUMP
.
MADV_FREE
Specify that the application no longer needs the pages in the given range.
