1 ================= 2 Memory Management 3 ================= 4 5 Linux memory management subsystem is responsible, as the name implies, 6 for managing the memory in the system. This includes implementation of 7 virtual memory and demand paging, memory allocation both for kernel 8 internal structures and user space programs, mapping of files into 9 processes address space and many other cool things. 10 11 Linux memory management is a complex system with many configurable 12 settings. Most of these settings are available via ``/proc`` 13 filesystem and can be queried and adjusted using ``sysctl``. These APIs 14 are described in Documentation/admin-guide/sysctl/vm.rst and in `man 5 proc`_. 15 16 .. _man 5 proc: http://man7.org/linux/man-pages/man5/proc.5.html 17 18 Linux memory management has its own jargon and if you are not yet 19 familiar with it, consider reading Documentation/admin-guide/mm/concepts.rst. 20 21 Here we document in detail how to interact with various mechanisms in 22 the Linux memory management. 23 24 .. toctree:: 25 :maxdepth: 1 26 27 concepts 28 cma_debugfs 29 damon/index 30 hugetlbpage 31 idle_page_tracking 32 ksm 33 memory-hotplug 34 multigen_lru 35 nommu-mmap 36 numa_memory_policy 37 numaperf 38 pagemap 39 shrinker_debugfs 40 soft-dirty 41 swap_numa 42 transhuge 43 userfaultfd 44 zswap
