+4. USERSPACE PROGRAMMING
+------------------------
+
+The cfag12864bfb describes a framebuffer device (/dev/fbX).
+
+It has a size of 1024 bytes = 1 Kbyte.
+Each bit represents one pixel. If the bit is high, the pixel will
+turn on. If the pixel is low, the pixel will turn off.
+
+You can use the framebuffer as a file: fopen, fwrite, fclose...
+Although the LCD won't get updated until the next refresh time arrives.
+
+Also, you can mmap the framebuffer: open & mmap, munmap & close...
+which is the best option for most uses.
+
+Check Documentation/auxdisplay/cfag12864b-example.c
+for a real working userspace complete program with usage examples.

+ Semantics and Behavior of Local Atomic Operations
+
+ Mathieu Desnoyers
+
+
+ This document explains the purpose of the local atomic operations, how
+to implement them for any given architecture and shows how they can be used
+properly. It also stresses on the precautions that must be taken when reading
+those local variables across CPUs when the order of memory writes matters.
+
+
+
+* Purpose of local atomic operations
+
+Local atomic operations are meant to provide fast and highly reentrant per CPU
+counters. 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 is made so a cast from this type to a
+long fails. The definition looks like :
+
+typedef struct { atomic_long_t a; } local_t;
+
+
+* How to use local atomic operations
+
+#include <linux/percpu.h>
+#include <asm/local.h>
+
+static DEFINE_PER_CPU(local_t, counters) = LOCAL_INIT(0);
+
+
+* Counting
+
+Counting is done on all the bits of a signed long.
+
+In preemptible context, use get_cpu_var() and put_cpu_var() around local atomic
+operations : it makes sure that preemption is disabled around write access to
+the per cpu variable. For instance :
+
+ local_inc(&get_cpu_var(counters));
+ put_cpu_var(counters);
+
+If you are already in a preemption-safe context, you can directly use
+__get_cpu_var() instead.
+
+ local_inc(&__get_cpu_var(counters));
+
+
+
+* Reading the counters
+
+Those local counters can be read from foreign CPUs to sum the count. Note that
+the data seen by local_read across CPUs must be considered to be out of order
+relatively to other memory writes happening on the CPU that owns the data.
+
+ long sum = 0;
+ for_each_online_cpu(cpu)
+ sum += local_read(&per_cpu(counters, cpu));
+
+If you want to use a remote local_read to synchronize access to a resource
+between CPUs, explicit smp_wmb() and smp_rmb() memory barriers must be used
+respectively on the writer and the reader CPUs. It would be the case if you use
+the local_t variable as a counter of bytes written in a buffer : there should
+be a smp_wmb() between the buffer write and the counter increment and also a
+smp_rmb() between the counter read and the buffer read.
+
+
+Here is a sample module which implements a basic per cpu counter using local.h.

+Red-black Trees (rbtree) in Linux
+January 18, 2007
+Rob Landley <rob@landley.net>
+=============================
+
+What are red-black trees, and what are they for?
+------------------------------------------------
+
+Red-black trees are a type of self-balancing binary search tree, used for
+storing sortable key/value data pairs. 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));

+ ---help---
+ If you have a LCD controlled by one or more KS0108
+ controllers, say Y. You will need also another more specific
+ driver for your LCD.
+
+ Depends on Parallel Port support. If you say Y at
+ parport, you will be able to compile this as a module (M)
+ and built-in as well (Y).
+
+ To compile this as a module, choose M here:
+ the module will be called ks0108.
+
+ If unsure, say N.
+
+config KS0108_PORT
+ hex "Parallel port where the LCD is connected"
+ depends on KS0108
+ default 0x378
+ ---help---
+ The address of the parallel port where the LCD is connected.
+
+ The first standard parallel port address is 0x378.
+ The second standard parallel port address is 0x278.
+ The third standard parallel port address is 0x3BC.
+
+ You can specify a different address if you need.
+
+ If you don't know what I'm talking about, load the parport module,
+ and execute "dmesg" or "cat /proc/ioports". You can see there how
+ many parallel ports are present and which address each one has.
+
+ Usually you only need to use 0x378.
+
+ If you compile this as a module, you can still override this
+ using the module parameters.
+
+config KS0108_DELAY
+ int "Delay between each control writing (microseconds)"
+ depends on KS0108
+ default "2"
+ ---help---
+ Amount of time the ks0108 should wait between each control write
+ to the parallel port.
+
+ If your driver seems to miss random writings, increment this.
+
+ If you don't know what I'm talking about, ignore it.
+
+ If you compile this as a module, you can still override this
+ value using the module parameters.
+
+config CFAG12864B
+ tristate "CFAG12864B LCD"
+ depends on X86
+ depends on FB
+ depends on KS0108
+ default n
+ ---help---
+ If you have a Crystalfontz 128x64 2-color LCD, cfag12864b Series,
+ say Y. You also need the ks0108 LCD Controller driver.
+
+ For help about how to wire your LCD to the parallel port,
+ check Documentation/auxdisplay/cfag12864b
+
+ Depends on the x86 arch and the framebuffer support.
+
+ The LCD framebuffer driver can be attached to a console.
+ It will work fine. However, you can't attach it to the fbdev driver
+ of the xorg server.
+
+ To compile this as a module, choose M here:
+ the modules will be called cfag12864b and cfag12864bfb.
+
+ If unsure, say N.
+
+config CFAG12864B_RATE
+ int "Refresh rate (hertz)"
+ depends on CFAG12864B
+ default "20"
+ ---help---
+ Refresh rate of the LCD.
+
+ As the LCD is not memory mapped, the driver has to make the work by
+ software. This means you should be careful setting this value higher.
+ If your CPUs are really slow or you feel the system is slowed down,
+ decrease the value.
+
+ Be careful modifying this value to a very high value:
+ You can freeze the computer, or the LCD maybe can't draw as fast as you
+ are requesting.
+
+ If you don't know what I'm talking about, ignore it.
+
+ If you compile this as a module, you can still override this
+ value using the module parameters.

+ help
+ Say "yes" here to get direct support for the real time clock
+ found in every PC or ACPI-based system, and some other boards.
+ Specifically the original MC146818, compatibles like those in
+ PC south bridges, the DS12887 or M48T86, some multifunction
+ or LPC bus chips, and so on.
+
+ Your system will need to define the platform device used by
+ this driver, otherwise it won't be accessible. This means
+ you can safely enable this driver if you don't know whether
+ or not your board has this kind of hardware.
+
+ This driver can also be built as a module. If so, the module
+ will be called rtc-cmos.
