|
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/sysctl/vm.txt and in `man 5 proc`_.

||
|
|
||
|
.. _man 5 proc: http://man7.org/linux/man-pages/man5/proc.5.html
|
||
|
|
||
|
Here we document in detail how to interact with various mechanisms in
|
||
|
the Linux memory management.
