They minimize the performance cost of standard atomic operations by +removing the LOCK prefix and memory barriers normally required to synchronize +across CPUs. + +Having fast per CPU atomic counters is interesting in many cases : it does not +require disabling interrupts to protect from interrupt handlers and it permits +coherent counters in NMI handlers. It is especially useful for tracing purposes +and for various performance monitoring counters. + +Local atomic operations only guarantee variable modification atomicity wrt the +CPU which owns the data. Therefore, care must taken to make sure that only one +CPU writes to the local_t data. This is done by using per cpu data and making +sure that we modify it from within a preemption safe context. It is however +permitted to read local_t data from any CPU : it will then appear to be written +out of order wrt other memory writes on the owner CPU. + + +* Implementation for a given architecture + +It can be done by slightly modifying the standard atomic operations : only +their UP variant must be kept. It typically means removing LOCK prefix (on +i386 and x86_64) and any SMP sychronization barrier. If the architecture does +not have a different behavior between SMP and UP, including asm-generic/local.h +in your archtecture's local.h is sufficient. + +The local_t type is defined as an opaque signed long by embedding an +atomic_long_t inside a structure.

This differs from radix trees (which +are used to efficiently store sparse arrays and thus use long integer indexes +to insert/access/delete nodes) and hash tables (which are not kept sorted to +be easily traversed in order, and must be tuned for a specific size and +hash function where rbtrees scale gracefully storing arbitrary keys). + +Red-black trees are similar to AVL trees, but provide faster real-time bounded +worst case performance for insertion and deletion (at most two rotations and +three rotations, respectively, to balance the tree), with slightly slower +(but still O(log n)) lookup time. + +To quote Linux Weekly News: + + There are a number of red-black trees in use in the kernel. + The anticipatory, deadline, and CFQ I/O schedulers all employ + rbtrees to track requests; the packet CD/DVD driver does the same. + The high-resolution timer code uses an rbtree to organize outstanding + timer requests. The ext3 filesystem tracks directory entries in a + red-black tree. Virtual memory areas (VMAs) are tracked with red-black + trees, as are epoll file descriptors, cryptographic keys, and network + packets in the "hierarchical token bucket" scheduler. + +This document covers use of the Linux rbtree implementation. For more +information on the nature and implementation of Red Black Trees, see: + + Linux Weekly News article on red-black trees + http://lwn.net/Articles/184495/ + + Wikipedia entry on red-black trees + http://en.wikipedia.org/wiki/Red-black_tree + +Linux implementation of red-black trees +--------------------------------------- + +Linux's rbtree implementation lives in the file "lib/rbtree.c". To use it, +"#include <linux/rbtree.h>". + +The Linux rbtree implementation is optimized for speed, and thus has one +less layer of indirection (and better cache locality) than more traditional +tree implementations. Instead of using pointers to separate rb_node and data +structures, each instance of struct rb_node is embedded in the data structure +it organizes. And instead of using a comparison callback function pointer, +users are expected to write their own tree search and insert functions +which call the provided rbtree functions. Locking is also left up to the +user of the rbtree code. + +Creating a new rbtree +--------------------- + +Data nodes in an rbtree tree are structures containing a struct rb_node member: + + struct mytype { + struct rb_node node; + char *keystring; + }; + +When dealing with a pointer to the embedded struct rb_node, the containing data +structure may be accessed with the standard container_of() macro. In addition, +individual members may be accessed directly via rb_entry(node, type, member). + +At the root of each rbtree is an rb_root structure, which is initialized to be +empty via: + + struct rb_root mytree = RB_ROOT; + +Searching for a value in an rbtree +---------------------------------- + +Writing a search function for your tree is fairly straightforward: start at the +root, compare each value, and follow the left or right branch as necessary. + +Example: + + struct mytype *my_search(struct rb_root *root, char *string) + { + struct rb_node *node = root->rb_node; + + while (node) { + struct mytype *data = container_of(node, struct mytype, node); + int result; + + result = strcmp(string, data->keystring); + + if (result < 0) + node = node->rb_left; + else if (result > 0) + node = node->rb_right; + else + return data; + } + return NULL; + } + +Inserting data into an rbtree +----------------------------- + +Inserting data in the tree involves first searching for the place to insert the +new node, then inserting the node and rebalancing ("recoloring") the tree. + +The search for insertion differs from the previous search by finding the +location of the pointer on which to graft the new node. The new node also +needs a link to its parent node for rebalancing purposes. + +Example: + + int my_insert(struct rb_root *root, struct mytype *data) + { + struct rb_node **new = &(root->rb_node), *parent = NULL; + + /* Figure out where to put new node */ + while (*new) { + struct mytype *this = container_of(*new, struct mytype, node); + int result = strcmp(data->keystring, this->keystring); + + parent = *new; + if (result < 0) + new = &((*new)->rb_left); + else if (result > 0) + new = &((*new)->rb_right); + else + return FALSE; + } + + /* Add new node and rebalance tree. */ + rb_link_node(data->node, parent, new); + rb_insert_color(data->node, root); + + return TRUE; + } + +Removing or replacing existing data in an rbtree +------------------------------------------------ + +To remove an existing node from a tree, call: + + void rb_erase(struct rb_node *victim, struct rb_root *tree); + +Example: + + struct mytype *data = mysearch(mytree, "walrus"); + + if (data) { + rb_erase(data->node, mytree); + myfree(data); + } + +To replace an existing node in a tree with a new one with the same key, call: + + void rb_replace_node(struct rb_node *old, struct rb_node *new, + struct rb_root *tree); + +Replacing a node this way does not re-sort the tree: If the new node doesn't +have the same key as the old node, the rbtree will probably become corrupted. + +Iterating through the elements stored in an rbtree (in sort order) +------------------------------------------------------------------ + +Four functions are provided for iterating through an rbtree's contents in +sorted order. These work on arbitrary trees, and should not need to be +modified or wrapped (except for locking purposes): + + struct rb_node *rb_first(struct rb_root *tree); + struct rb_node *rb_last(struct rb_root *tree); + struct rb_node *rb_next(struct rb_node *node); + struct rb_node *rb_prev(struct rb_node *node); + +To start iterating, call rb_first() or rb_last() with a pointer to the root +of the tree, which will return a pointer to the node structure contained in +the first or last element in the tree. To continue, fetch the next or previous +node by calling rb_next() or rb_prev() on the current node. This will return +NULL when there are no more nodes left. + +The iterator functions return a pointer to the embedded struct rb_node, from +which the containing data structure may be accessed with the container_of() +macro, and individual members may be accessed directly via +rb_entry(node, type, member). + +Example: + + struct rb_node *node; + for (node = rb_first(&mytree); node; node = rb_next(node)) + printk("key=%s\n", rb_entry(node, int, keystring)); + diff --git a/Documentation/rtc.txt b/Documentation/rtc.txt index 7cf1ec5..1ef6bb8 100644 --- a/Documentation/rtc.txt +++ b/Documentation/rtc.txt @@ -149,7 +149,7 @@ RTC class framework, but can't be supported by the older driver. is connected to an IRQ line, it can often issue an alarm IRQ up to 24 hours in the future. - * RTC_WKALM_SET, RTC_WKALM_READ ...
