 | Core API Documentation | 
 | ====================== | 
 |  | 
 | This is the beginning of a manual for core kernel APIs.  The conversion | 
 | (and writing!) of documents for this manual is much appreciated! | 
 |  | 
 | Core utilities | 
 | ============== | 
 |  | 
 | This section has general and "core core" documentation.  The first is a | 
 | massive grab-bag of kerneldoc info left over from the docbook days; it | 
 | should really be broken up someday when somebody finds the energy to do | 
 | it. |

 |    printk-basics | 
 |    printk-formats | 
 |    symbol-namespaces | 
 |  | 
 | Data structures and low-level utilities | 
 | ======================================= | 
 |  | 
 | Library functionality that is used throughout the kernel. | 
 |  | 
 | .. toctree:: | 
 |    :maxdepth: 1 | 
 |  | 
 |    kobject | 
 |    kref |

 |    rbtree | 
 |    generic-radix-tree | 
 |    packing | 
 |    timekeeping | 
 |    errseq | 
 |  | 
 | Concurrency primitives | 
 | ====================== | 
 |  | 
 | How Linux keeps everything from happening at the same time.  See | 
 | :doc:`/locking/index` for more related documentation. |

 |  | 
 | Low-level hardware management | 
 | ============================= | 
 |  | 
 | Cache management, managing CPU hotplug, etc. | 
 |  | 
 | .. toctree:: | 
 |    :maxdepth: 1 | 
 |  | 
 |    cachetlb | 
 |    cpu_hotplug |

 |    genericirq | 
 |    protection-keys | 
 |  | 
 | Memory management | 
 | ================= | 
 |  | 
 | How to allocate and use memory in the kernel.  Note that there is a lot | 
 | more memory-management documentation in :doc:`/vm/index`. |

 | =============== | 
 |  | 
 | Documents that don't fit elsewhere or which have yet to be categorized. |
