<p>Do not make the pages in this range available to the child
after a fork(2). This is useful to prevent copy-on-write
semantics from changing the physical location of a page if
the parent writes to it after a fork(2). (Such page
relocations cause problems for hardware that DMAs into the
page.)</p>

<p>Undo the effect of MADV_DONTFORK, restoring the default
behavior, whereby a mapping is inherited across fork(2).</p>
</div><section id="variant.Mergeable" class="variant"><a href="#variant.Mergeable" class="anchor">§</a><h3 class="code-header">Mergeable = 12</h3></section><div class="docblock"><p><strong>MADV_MERGEABLE</strong> - Linux only (since Linux 2.6.32)</p>
<p>Enable Kernel Samepage Merging (KSM) for the pages in the
range specified by addr and length. The kernel regularly
scans those areas of user memory that have been marked as
mergeable, looking for pages with identical content.
These are replaced by a single write-protected page (which
is automatically copied if a process later wants to update
the content of the page). KSM merges only private
anonymous pages (see mmap(2)).</p>
<p>The KSM feature is intended for applications that generate
many instances of the same data (e.g., virtualization
systems such as KVM). It can consume a lot of processing
power; use with care. See the Linux kernel source file
Documentation/admin-guide/mm/ksm.rst for more details.</p>
<p>The MADV_MERGEABLE and MADV_UNMERGEABLE operations are
available only if the kernel was configured with
CONFIG_KSM.</p>
</div><section id="variant.Unmergeable" class="variant"><a href="#variant.Unmergeable" class="anchor">§</a><h3 class="code-header">Unmergeable = 13</h3></section><div class="docblock"><p><strong>MADV_UNMERGEABLE</strong> - Linux only (since Linux 2.6.32)</p>
<p>Undo the effect of an earlier MADV_MERGEABLE operation on
the specified address range; KSM unmerges whatever pages
it had merged in the address range specified by addr and
length.</p>
</div><section id="variant.HugePage" class="variant"><a href="#variant.HugePage" class="anchor">§</a><h3 class="code-header">HugePage = 14</h3></section><div class="docblock"><p><strong>MADV_HUGEPAGE</strong> - Linux only (since Linux 2.6.38)</p>
<p>Enable Transparent Huge Pages (THP) for pages in the range
specified by addr and length. Currently, Transparent Huge
Pages work only with private anonymous pages (see
mmap(2)). The kernel will regularly scan the areas marked
as huge page candidates to replace them with huge pages.
The kernel will also allocate huge pages directly when the
region is naturally aligned to the huge page size (see
posix_memalign(2)).</p>
<p>This feature is primarily aimed at applications that use
large mappings of data and access large regions of that
memory at a time (e.g., virtualization systems such as
QEMU). It can very easily waste memory (e.g., a 2 MB
mapping that only ever accesses 1 byte will result in 2 MB
of wired memory instead of one 4 KB page). See the Linux
kernel source file
Documentation/admin-guide/mm/transhuge.rst for more
details.</p>
<p>Most common kernels configurations provide MADV_HUGEPAGE-
style behavior by default, and thus MADV_HUGEPAGE is
normally not necessary. It is mostly intended for
embedded systems, where MADV_HUGEPAGE-style behavior may
not be enabled by default in the kernel. On such systems,
this flag can be used in order to selectively enable THP.
Whenever MADV_HUGEPAGE is used, it should always be in
regions of memory with an access pattern that the
developer knows in advance wont risk to increase the
memory footprint of the application when transparent
hugepages are enabled.</p>
<p>The MADV_HUGEPAGE and MADV_NOHUGEPAGE operations are
available only if the kernel was configured with
CONFIG_TRANSPARENT_HUGEPAGE.</p>
</div><section id="variant.NoHugePage" class="variant"><a href="#variant.NoHugePage" class="anchor">§</a><h3 class="code-header">NoHugePage = 15</h3></section><div class="docblock"><p><strong>MADV_NOHUGEPAGE</strong> - Linux only (since Linux 2.6.38)</p>
<p>Ensures that memory in the address range specified by addr
and length will not be backed by transparent hugepages.</p>
</div><section id="variant.DontDump" class="variant"><a href="#variant.DontDump" class="anchor">§</a><h3 class="code-header">DontDump = 16</h3></section><div class="docblock"><p><strong>MADV_DONTDUMP</strong> - Linux only (since Linux 3.4)</p>
<p>Exclude from a core dump those pages in the range
specified by addr and length. This is useful in
applications that have large areas of memory that are
known not to be useful in a core dump. The effect of
<strong>MADV_DONTDUMP</strong> takes precedence over the bit mask that is
set via the <code>/proc/[pid]/coredump_filter</code> file (see
core(5)).</p>
</div><section id="variant.DoDump" class="variant"><a href="#variant.DoDump" class="anchor">§</a><h3 class="code-header">DoDump = 17</h3></section><div class="docblock"><p><strong>MADV_DODUMP</strong> - Linux only (since Linux 3.4)</p>
<p>Undo the effect of an earlier MADV_DONTDUMP.</p>
</div><section id="variant.HwPoison" class="variant"><a href="#variant.HwPoison" class="anchor">§</a><h3 class="code-header">HwPoison = 100</h3></section><div class="docblock"><p><strong>MADV_HWPOISON</strong> - Linux only (since Linux 2.6.32)</p>
<p>Poison the pages in the range specified by addr and length
and handle subsequent references to those pages like a
hardware memory corruption. This operation is available
only for privileged (CAP_SYS_ADMIN) processes. This
operation may result in the calling process receiving a
SIGBUS and the page being unmapped.</p>
<p>This feature is intended for testing of memory error-
handling code; it is available only if the kernel was
configured with CONFIG_MEMORY_FAILURE.</p>
</div><section id="variant.PopulateRead" class="variant"><a href="#variant.PopulateRead" class="anchor">§</a><h3 class="code-header">PopulateRead = 22</h3></section><div class="docblock"><p><strong>MADV_POPULATE_READ</strong> - Linux only (since Linux 5.14)</p>
<p>Populate (prefault) page tables readable, faulting in all
pages in the range just as if manually reading from each
page; however, avoid the actual memory access that would have
been performed after handling the fault.</p>
<p>In contrast to MAP_POPULATE, MADV_POPULATE_READ does not hide
errors, can be applied to (parts of) existing mappings and
will always populate (prefault) page tables readable. One
example use case is prefaulting a file mapping, reading all
file content from disk; however, pages wont be dirtied and
consequently wont have to be written back to disk when
evicting the pages from memory.</p>
<p>Depending on the underlying mapping, map the shared zeropage,
preallocate memory or read the underlying file; files with
holes might or might not preallocate blocks. If populating
fails, a SIGBUS signal is not generated; instead, an error is
returned.</p>
<p>If MADV_POPULATE_READ succeeds, all page tables have been
populated (prefaulted) readable once. If MADV_POPULATE_READ
fails, some page tables might have been populated.</p>
<p>MADV_POPULATE_READ cannot be applied to mappings without read
permissions and special mappings, for example, mappings
marked with kernel-internal flags such as VM_PFNMAP or VM_IO,
or secret memory regions created using memfd_secret(2).</p>
<p>Note that with MADV_POPULATE_READ, the process can be killed
at any moment when the system runs out of memory.</p>

<p>Populate (prefault) page tables writable, faulting in all
pages in the range just as if manually writing to each each
page; however, avoid the actual memory access that would have
been performed after handling the fault.</p>
<p>In contrast to MAP_POPULATE, MADV_POPULATE_WRITE does not
hide errors, can be applied to (parts of) existing mappings
and will always populate (prefault) page tables writable.
One example use case is preallocating memory, breaking any
CoW (Copy on Write).</p>
<p>Depending on the underlying mapping, preallocate memory or
read the underlying file; files with holes will preallocate
blocks. If populating fails, a SIGBUS signal is not gener
ated; instead, an error is returned.</p>
<p>If MADV_POPULATE_WRITE succeeds, all page tables have been

fails, some page tables might have been populated.</p>
