Memory Management
|
|
=================
|
|
|
|
Linux memory management subsystem is responsible, as the name implies,
|
|
for managing the memory in the system. This includes implemnetation of
|
|
virtual memory and demand paging, memory allocation both for kernel
|
|
internal structures and user space programms, mapping of files into
|
|
processes address space and many other cool things.
|
|
|
|
Linux memory management is a complex system with many configurable
|
|
settings. Most of these settings are available via ``/proc``
|
|
filesystem and can be quired and adjusted using ``sysctl``. These APIs
|
|
are described in Documentation/admin-guide/sysctl/vm.rst and in `man 5 proc`_.

|
|
Linux memory management has its own jargon and if you are not yet
|
|
familiar with it, consider reading
|
|
:ref:`Documentation/admin-guide/mm/concepts.rst <mm_concepts>`.
|
|
|
|
Here we document in detail how to interact with various mechanisms in
|
|
the Linux memory management.
