+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.

+Devres - Managed Device Resource
+================================
+
+Tejun Heo <teheo@suse.de>
+
+First draft 10 January 2007
+
+
+1. Intro : Huh? Devres?
+2. Devres : Devres in a nutshell
+3. Devres Group : Group devres'es and release them together
+4. Details : Life time rules, calling context, ...
+5. Overhead : How much do we have to pay for this?
+6. List of managed interfaces : Currently implemented managed interfaces
+
+
+ 1. Intro
+ --------
+
+devres came up while trying to convert libata to use iomap. Each
+iomapped address should be kept and unmapped on driver detach. For
+example, a plain SFF ATA controller (that is, good old PCI IDE) in
+native mode makes use of 5 PCI BARs and all of them should be
+maintained.
+
+As with many other device drivers, libata low level drivers have
+sufficient bugs in ->remove and ->probe failure path. Well, yes,
+that's probably because libata low level driver developers are lazy
+bunch, but aren't all low level driver developers? After spending a
+day fiddling with braindamaged hardware with no document or
+braindamaged document, if it's finally working, well, it's working.
+
+For one reason or another, low level drivers don't receive as much
+attention or testing as core code, and bugs on driver detach or
+initilaization failure doesn't happen often enough to be noticeable.
+Init failure path is worse because it's much less travelled while
+needs to handle multiple entry points.
+
+So, many low level drivers end up leaking resources on driver detach
+and having half broken failure path implementation in ->probe() which
+would leak resources or even cause oops when failure occurs. iomap
+adds more to this mix. So do msi and msix.
+
+
+ 2. Devres
+ ---------
+
+devres is basically linked list of arbitrarily sized memory areas
+associated with a struct device. Each devres entry is associated with
+a release function. A devres can be released in several ways. No
+matter what, all devres entries are released on driver detach. On
+release, the associated release function is invoked and then the
+devres entry is freed.
+
+Managed interface is created for resources commonly used by device
+drivers using devres. For example, coherent DMA memory is acquired
+using dma_alloc_coherent(). The managed version is called
+dmam_alloc_coherent(). It is identical to dma_alloc_coherent() except
+for the DMA memory allocated using it is managed and will be
+automatically released on driver detach. Implementation looks like
+the following.
+
+ struct dma_devres {
+ size_t size;
+ void *vaddr;
+ dma_addr_t dma_handle;
+ };
+
+ static void dmam_coherent_release(struct device *dev, void *res)
+ {
+ struct dma_devres *this = res;
+
+ dma_free_coherent(dev, this->size, this->vaddr, this->dma_handle);
+ }
+
+ dmam_alloc_coherent(dev, size, dma_handle, gfp)
+ {
+ struct dma_devres *dr;
+ void *vaddr;
+
+ dr = devres_alloc(dmam_coherent_release, sizeof(*dr), gfp);
+ ...
+
+ /* alloc DMA memory as usual */
+ vaddr = dma_alloc_coherent(...);
+ ...
+
+ /* record size, vaddr, dma_handle in dr */
+ dr->vaddr = vaddr;
+ ...
+
+ devres_add(dev, dr);
+
+ return vaddr;
+ }
+
+If a driver uses dmam_alloc_coherent(), the area is guaranteed to be
+freed whether initialization fails half-way or the device gets
+detached. If most resources are acquired using managed interface, a
+driver can have much simpler init and exit code. Init path basically
+looks like the following.
+
+ my_init_one()
+ {
+ struct mydev *d;
+
+ d = devm_kzalloc(dev, sizeof(*d), GFP_KERNEL);
+ if (!d)
+ return -ENOMEM;
+
+ d->ring = dmam_alloc_coherent(...);
+ if (!d->ring)
+ return -ENOMEM;
+
+ if (check something)
+ return -EINVAL;
+ ...
+
+ return register_to_upper_layer(d);
+ }
+
+And exit path,
+
+ my_remove_one()
+ {
+ unregister_from_upper_layer(d);
+ shutdown_my_hardware();
+ }
+
+As shown above, low level drivers can be simplified a lot by using
+devres. Complexity is shifted from less maintained low level drivers
+to better maintained higher layer. Also, as init failure path is
+shared with exit path, both can get more testing.
+
+
+ 3. Devres group
+ ---------------
+
+Devres entries can be grouped using devres group. When a group is
+released, all contained normal devres entries and properly nested
+groups are released. One usage is to rollback series of acquired
+resources on failure. For example,
+
+ if (!devres_open_group(dev, NULL, GFP_KERNEL))
+ return -ENOMEM;
+
+ acquire A;
+ if (failed)
+ goto err;
+
+ acquire B;
+ if (failed)
+ goto err;
+ ...
+
+ devres_remove_group(dev, NULL);
+ return 0;
+
+ err:
+ devres_release_group(dev, NULL);
+ return err_code;
+
+As resource acquision failure usually means probe failure, constructs
+like above are usually useful in midlayer driver (e.g. libata core
+layer) where interface function shouldn't have side effect on failure.
+For LLDs, just returning error code suffices in most cases.
+
+Each group is identified by void *id. It can either be explicitly
+specified by @id argument to devres_open_group() or automatically
+created by passing NULL as @id as in the above example. In both
+cases, devres_open_group() returns the group's id. The returned id
+can be passed to other devres functions to select the target group.
+If NULL is given to those functions, the latest open group is
+selected.
+
+For example, you can do something like the following.
+
+ int my_midlayer_create_something()
+ {
+ if (!devres_open_group(dev, my_midlayer_create_something, GFP_KERNEL))
+ return -ENOMEM;
+
+ ...
+
+ devres_close_group(dev, my_midlayer_something);
+ return 0;
+ }
+
+ void my_midlayer_destroy_something()
+ {
+ devres_release_group(dev, my_midlayer_create_soemthing);
+ }
+
+
+ 4. Details
+ ----------
+
+Lifetime of a devres entry begins on devres allocation and finishes
+when it is released or destroyed (removed and freed) - no reference
+counting.
+
+devres core guarantees atomicity to all basic devres operations and
+has support for single-instance devres types (atomic
+lookup-and-add-if-not-found). Other than that, synchronizing
+concurrent accesses to allocated devres data is caller's
+responsibility. This is usually non-issue because bus ops and
+resource allocations already do the job.
+
+For an example of single-instance devres type, read pcim_iomap_table()
+in lib/iomap.c.
+
+All devres interface functions can be called without context if the
+right gfp mask is given.
+
+
+ 5. Overhead
+ -----------
+
+Each devres bookkeeping info is allocated together with requested data
+area. With debug option turned off, bookkeeping info occupies 16
+bytes on 32bit machines and 24 bytes on 64bit (three pointers rounded
+up to ull alignment). If singly linked list is used, it can be
+reduced to two pointers (8 bytes on 32bit, 16 bytes on 64bit).
+
+Each devres group occupies 8 pointers. It can be reduced to 6 if
+singly linked list is used.
+
+Memory space overhead on ahci controller with two ports is between 300
+and 400 bytes on 32bit machine after naive conversion (we can
+certainly invest a bit more effort into libata core layer).

+ 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));
+
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 ... RTCs that can issue alarms beyond
+ * RTC_WKALM_SET, RTC_WKALM_RD ... RTCs that can issue alarms beyond
the next 24 hours use a slightly more powerful API, which supports
setting the longer alarm time and enabling its IRQ using a single
request (using the same model as EFI firmware).
operational state. For example, a system could enter a deep power saving
state until it's time to execute some scheduled tasks.
+Note that many of these ioctls need not actually be implemented by your
+driver. The common rtc-dev interface handles many of these nicely if your
+driver returns ENOIOCTLCMD. Some common examples:
+
+ * RTC_RD_TIME, RTC_SET_TIME: the read_time/set_time functions will be
+ called with appropriate values.
+
+ * RTC_ALM_SET, RTC_ALM_READ, RTC_WKALM_SET, RTC_WKALM_RD: the
+ set_alarm/read_alarm functions will be called. To differentiate
+ between the ALM and WKALM, check the larger fields of the rtc_wkalrm
+ struct (like tm_year). These will be set to -1 when using ALM and
+ will be set to proper values when using WKALM.
+
+ * RTC_IRQP_SET, RTC_IRQP_READ: the irq_set_freq function will be called
+ to set the frequency while the framework will handle the read for you
+ since the frequency is stored in the irq_freq member of the rtc_device
+ structure. Also make sure you set the max_user_freq member in your
+ initialization routines so the framework can sanity check the user
+ input for you.
+
+If all else fails, check out the rtc-test.c driver!

+ASoC currently supports the three main Digital Audio Interfaces (DAI) found on
+SoC controllers and portable audio CODECS today, namely AC97, I2S and PCM.
+
+
+AC97
+====
+
+ AC97 is a five wire interface commonly found on many PC sound cards. It is
+now also popular in many portable devices. This DAI has a reset line and time
+multiplexes its data on its SDATA_OUT (playback) and SDATA_IN (capture) lines.
+The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
+frame (FRAME) (usually 48kHz) is always driven by the controller. Each AC97
+frame is 21uS long and is divided into 13 time slots.
+
+The AC97 specification can be found at :-
+http://www.intel.com/design/chipsets/audio/ac97_r23.pdf
+
+
+I2S
+===
+
+ I2S is a common 4 wire DAI used in HiFi, STB and portable devices. The Tx and
+Rx lines are used for audio transmision, whilst the bit clock (BCLK) and
+left/right clock (LRC) synchronise the link. I2S is flexible in that either the
+controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
+usually varies depending on the sample rate and the master system clock
+(SYSCLK). LRCLK is the same as the sample rate. A few devices support separate
+ADC and DAC LRCLK's, this allows for similtanious capture and playback at
+different sample rates.
+
+I2S has several different operating modes:-
+
+ o I2S - MSB is transmitted on the falling edge of the first BCLK after LRC
+ transition.
+
+ o Left Justified - MSB is transmitted on transition of LRC.
+
+ o Right Justified - MSB is transmitted sample size BCLK's before LRC
+ transition.
+
+PCM
+===
+
+PCM is another 4 wire interface, very similar to I2S, that can support a more
+flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
+to synchronise the link whilst the Tx and Rx lines are used to transmit and
+receive the audio data. Bit clock usually varies depending on sample rate
+whilst sync runs at the sample rate. PCM also supports Time Division
+Multiplexing (TDM) in that several devices can use the bus similtaniuosly (This
+is sometimes referred to as network mode).
+
+Common PCM operating modes:-
+
+ o Mode A - MSB is transmitted on falling edge of first BCLK after FRAME/SYNC.
+
+ o Mode B - MSB is transmitted on rising edge of FRAME/SYNC.

+Audio Clocking
+==============
+
+This text describes the audio clocking terms in ASoC and digital audio in
+general. Note: Audio clocking can be complex !
+
+
+Master Clock
+------------
+
+Every audio subsystem is driven by a master clock (sometimes refered to as MCLK
+or SYSCLK). This audio master clock can be derived from a number of sources
+(e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
+audio playback and capture sample rates.
+
+Some master clocks (e.g. PLL's and CPU based clocks) are configuarble in that
+their speed can be altered by software (depending on the system use and to save
+power). Other master clocks are fixed at at set frequency (i.e. crystals).
+
+
+DAI Clocks
+----------
+The Digital Audio Interface is usually driven by a Bit Clock (often referred to
+as BCLK). This clock is used to drive the digital audio data across the link
+between the codec and CPU.
+
+The DAI also has a frame clock to signal the start of each audio frame. This
+clock is sometimes referred to as LRC (left right clock) or FRAME. This clock
+runs at exactly the sample rate (LRC = Rate).
+
+Bit Clock can be generated as follows:-
+
+BCLK = MCLK / x
+
+ or
+
+BCLK = LRC * x
+
+ or
+
+BCLK = LRC * Channels * Word Size
+
+This relationship depends on the codec or SoC CPU in particular. In general
+it's best to configure BCLK to the lowest possible speed (depending on your
+rate, number of channels and wordsize) to save on power.
+
+It's also desireable to use the codec (if possible) to drive (or master) the
+audio clocks as it's usually gives more accurate sample rates than the CPU.
+
+
+

+ASoC Codec Driver
+=================
+
+The codec driver is generic and hardware independent code that configures the
+codec to provide audio capture and playback. It should contain no code that is
+specific to the target platform or machine. All platform and machine specific
+code should be added to the platform and machine drivers respectively.
+
+Each codec driver *must* provide the following features:-
+
+ 1) Codec DAI and PCM configuration
+ 2) Codec control IO - using I2C, 3 Wire(SPI) or both API's
+ 3) Mixers and audio controls
+ 4) Codec audio operations
+
+Optionally, codec drivers can also provide:-
+
+ 5) DAPM description.
+ 6) DAPM event handler.
+ 7) DAC Digital mute control.
+
+It's probably best to use this guide in conjuction with the existing codec
+driver code in sound/soc/codecs/
+
+ASoC Codec driver breakdown
+===========================
+
+1 - Codec DAI and PCM configuration
+-----------------------------------
+Each codec driver must have a struct snd_soc_codec_dai to define it's DAI and
+PCM's capablities and operations. This struct is exported so that it can be
+registered with the core by your machine driver.
+
+e.g.
+
+struct snd_soc_codec_dai wm8731_dai = {
+ .name = "WM8731",
+ /* playback capabilities */
+ .playback = {
+ .stream_name = "Playback",
+ .channels_min = 1,
+ .channels_max = 2,
+ .rates = WM8731_RATES,
+ .formats = WM8731_FORMATS,},
+ /* capture capabilities */
+ .capture = {
+ .stream_name = "Capture",
+ .channels_min = 1,
+ .channels_max = 2,
+ .rates = WM8731_RATES,
+ .formats = WM8731_FORMATS,},
+ /* pcm operations - see section 4 below */
+ .ops = {
+ .prepare = wm8731_pcm_prepare,
+ .hw_params = wm8731_hw_params,
+ .shutdown = wm8731_shutdown,
+ },
+ /* DAI operations - see DAI.txt */
+ .dai_ops = {
+ .digital_mute = wm8731_mute,
+ .set_sysclk = wm8731_set_dai_sysclk,
+ .set_fmt = wm8731_set_dai_fmt,
+ }
+};
+EXPORT_SYMBOL_GPL(wm8731_dai);
+
+
+2 - Codec control IO
+--------------------
+The codec can ususally be controlled via an I2C or SPI style interface (AC97
+combines control with data in the DAI). The codec drivers will have to provide
+functions to read and write the codec registers along with supplying a register
+cache:-
+
+ /* IO control data and register cache */
+ void *control_data; /* codec control (i2c/3wire) data */
+ void *reg_cache;
+
+Codec read/write should do any data formatting and call the hardware read write
+below to perform the IO. These functions are called by the core and alsa when
+performing DAPM or changing the mixer:-
+
+ unsigned int (*read)(struct snd_soc_codec *, unsigned int);
+ int (*write)(struct snd_soc_codec *, unsigned int, unsigned int);
+
+Codec hardware IO functions - usually points to either the I2C, SPI or AC97
+read/write:-
+
+ hw_write_t hw_write;
+ hw_read_t hw_read;
+
+
+3 - Mixers and audio controls
+-----------------------------
+All the codec mixers and audio controls can be defined using the convenience
+macros defined in soc.h.
+
+ #define SOC_SINGLE(xname, reg, shift, mask, invert)
+
+Defines a single control as follows:-
+
+ xname = Control name e.g. "Playback Volume"
+ reg = codec register
+ shift = control bit(s) offset in register
+ mask = control bit size(s) e.g. mask of 7 = 3 bits
+ invert = the control is inverted
+
+Other macros include:-
+
+ #define SOC_DOUBLE(xname, reg, shift_left, shift_right, mask, invert)
+
+A stereo control
+
+ #define SOC_DOUBLE_R(xname, reg_left, reg_right, shift, mask, invert)
+
+A stereo control spanning 2 registers
+
+ #define SOC_ENUM_SINGLE(xreg, xshift, xmask, xtexts)
+
+Defines an single enumerated control as follows:-
+
+ xreg = register
+ xshift = control bit(s) offset in register
+ xmask = control bit(s) size
+ xtexts = pointer to array of strings that describe each setting
+
+ #define SOC_ENUM_DOUBLE(xreg, xshift_l, xshift_r, xmask, xtexts)
+
+Defines a stereo enumerated control
+
+
+4 - Codec Audio Operations
+--------------------------
+The codec driver also supports the following alsa operations:-
+
+/* SoC audio ops */
+struct snd_soc_ops {
+ int (*startup)(struct snd_pcm_substream *);
+ void (*shutdown)(struct snd_pcm_substream *);
+ int (*hw_params)(struct snd_pcm_substream *, struct snd_pcm_hw_params *);
+ int (*hw_free)(struct snd_pcm_substream *);
+ int (*prepare)(struct snd_pcm_substream *);
+};
+
+Please refer to the alsa driver PCM documentation for details.
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
+
+
+5 - DAPM description.
+---------------------
+The Dynamic Audio Power Management description describes the codec's power
+components, their relationships and registers to the ASoC core. Please read
+dapm.txt for details of building the description.
+
+Please also see the examples in other codec drivers.
+
+
+6 - DAPM event handler
+----------------------
+This function is a callback that handles codec domain PM calls and system
+domain PM calls (e.g. suspend and resume). It's used to put the codec to sleep
+when not in use.
+
+Power states:-
+
+ SNDRV_CTL_POWER_D0: /* full On */
+ /* vref/mid, clk and osc on, active */
+
+ SNDRV_CTL_POWER_D1: /* partial On */
+ SNDRV_CTL_POWER_D2: /* partial On */
+
+ SNDRV_CTL_POWER_D3hot: /* Off, with power */
+ /* everything off except vref/vmid, inactive */
+
+ SNDRV_CTL_POWER_D3cold: /* Everything Off, without power */
+
+
+7 - Codec DAC digital mute control.
+------------------------------------
+Most codecs have a digital mute before the DAC's that can be used to minimise
+any system noise. The mute stops any digital data from entering the DAC.
+
+A callback can be created that is called by the core for each codec DAI when the
+mute is applied or freed.
+
+i.e.
+
+static int wm8974_mute(struct snd_soc_codec *codec,
+ struct snd_soc_codec_dai *dai, int mute)
+{
+ u16 mute_reg = wm8974_read_reg_cache(codec, WM8974_DAC) & 0xffbf;
+ if(mute)
+ wm8974_write(codec, WM8974_DAC, mute_reg | 0x40);
+ else
+ wm8974_write(codec, WM8974_DAC, mute_reg);
+ return 0;
+}

+Dynamic Audio Power Management for Portable Devices
+===================================================
+
+1. Description
+==============
+
+Dynamic Audio Power Management (DAPM) is designed to allow portable Linux devices
+to use the minimum amount of power within the audio subsystem at all times. It
+is independent of other kernel PM and as such, can easily co-exist with the
+other PM systems.
+
+DAPM is also completely transparent to all user space applications as all power
+switching is done within the ASoC core. No code changes or recompiling are
+required for user space applications. DAPM makes power switching descisions based
+upon any audio stream (capture/playback) activity and audio mixer settings
+within the device.
+
+DAPM spans the whole machine. It covers power control within the entire audio
+subsystem, this includes internal codec power blocks and machine level power
+systems.
+
+There are 4 power domains within DAPM
+
+ 1. Codec domain - VREF, VMID (core codec and audio power)
+ Usually controlled at codec probe/remove and suspend/resume, although
+ can be set at stream time if power is not needed for sidetone, etc.
+
+ 2. Platform/Machine domain - physically connected inputs and outputs
+ Is platform/machine and user action specific, is configured by the
+ machine driver and responds to asynchronous events e.g when HP
+ are inserted
+
+ 3. Path domain - audio susbsystem signal paths
+ Automatically set when mixer and mux settings are changed by the user.
+ e.g. alsamixer, amixer.
+
+ 4. Stream domain - DAC's and ADC's.
+ Enabled and disabled when stream playback/capture is started and
+ stopped respectively. e.g. aplay, arecord.
+
+All DAPM power switching descisons are made automatically by consulting an audio
+routing map of the whole machine. This map is specific to each machine and
+consists of the interconnections between every audio component (including
+internal codec components). All audio components that effect power are called
+widgets hereafter.
+
+
+2. DAPM Widgets
+===============
+
+Audio DAPM widgets fall into a number of types:-
+
+ o Mixer - Mixes several analog signals into a single analog signal.
+ o Mux - An analog switch that outputs only 1 of it's inputs.
+ o PGA - A programmable gain amplifier or attenuation widget.
+ o ADC - Analog to Digital Converter
+ o DAC - Digital to Analog Converter
+ o Switch - An analog switch
+ o Input - A codec input pin
+ o Output - A codec output pin
+ o Headphone - Headphone (and optional Jack)
+ o Mic - Mic (and optional Jack)
+ o Line - Line Input/Output (and optional Jack)
+ o Speaker - Speaker
+ o Pre - Special PRE widget (exec before all others)
+ o Post - Special POST widget (exec after all others)
+
+(Widgets are defined in include/sound/soc-dapm.h)
+
+Widgets are usually added in the codec driver and the machine driver. There are
+convience macros defined in soc-dapm.h that can be used to quickly build a
+list of widgets of the codecs and machines DAPM widgets.
+
+Most widgets have a name, register, shift and invert. Some widgets have extra
+parameters for stream name and kcontrols.
+
+
+2.1 Stream Domain Widgets
+-------------------------
+
+Stream Widgets relate to the stream power domain and only consist of ADC's
+(analog to digital converters) and DAC's (digital to analog converters).
+
+Stream widgets have the following format:-
+
+SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert),
+
+NOTE: the stream name must match the corresponding stream name in your codecs
+snd_soc_codec_dai.
+
+e.g. stream widgets for HiFi playback and capture
+
+SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1),
+SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1),
+
+
+2.2 Path Domain Widgets
+-----------------------
+
+Path domain widgets have a ability to control or effect the audio signal or
+audio paths within the audio subsystem. They have the following form:-
+
+SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls)
+
+Any widget kcontrols can be set using the controls and num_controls members.
+
+e.g. Mixer widget (the kcontrols are declared first)
+
+/* Output Mixer */
+static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = {
+SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0),
+SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0),
+SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0),
+};
+
+SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls,
+ ARRAY_SIZE(wm8731_output_mixer_controls)),
+
+
+2.3 Platform/Machine domain Widgets
+-----------------------------------
+
+Machine widgets are different from codec widgets in that they don't have a
+codec register bit associated with them. A machine widget is assigned to each
+machine audio component (non codec) that can be independently powered. e.g.
+
+ o Speaker Amp
+ o Microphone Bias
+ o Jack connectors
+
+A machine widget can have an optional call back.
+
+e.g. Jack connector widget for an external Mic that enables Mic Bias
+when the Mic is inserted:-
+
+static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event)
+{
+ if(SND_SOC_DAPM_EVENT_ON(event))
+ set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
+ else
+ reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
+
+ return 0;
+}
+
+SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias),
+
+
+2.4 Codec Domain
+----------------
+
+The Codec power domain has no widgets and is handled by the codecs DAPM event
+handler. This handler is called when the codec powerstate is changed wrt to any
+stream event or by kernel PM events.
+
+
+2.5 Virtual Widgets
+-------------------
+
+Sometimes widgets exist in the codec or machine audio map that don't have any
+corresponding register bit for power control. In this case it's necessary to
+create a virtual widget - a widget with no control bits e.g.
+
+SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0),
+
+This can be used to merge to signal paths together in software.
+
+After all the widgets have been defined, they can then be added to the DAPM
+subsystem individually with a call to snd_soc_dapm_new_control().
+
+
+3. Codec Widget Interconnections
+================================
+
+Widgets are connected to each other within the codec and machine by audio
+paths (called interconnections). Each interconnection must be defined in order
+to create a map of all audio paths between widgets.
+This is easiest with a diagram of the codec (and schematic of the machine audio
+system), as it requires joining widgets together via their audio signal paths.
+
+i.e. from the WM8731 codec's output mixer (wm8731.c)
+
+The WM8731 output mixer has 3 inputs (sources)
+
+ 1. Line Bypass Input
+ 2. DAC (HiFi playback)
+ 3. Mic Sidetone Input
+
+Each input in this example has a kcontrol associated with it (defined in example
+above) and is connected to the output mixer via it's kcontrol name. We can now
+connect the destination widget (wrt audio signal) with it's source widgets.
+
+ /* output mixer */
+ {"Output Mixer", "Line Bypass Switch", "Line Input"},
+ {"Output Mixer", "HiFi Playback Switch", "DAC"},
+ {"Output Mixer", "Mic Sidetone Switch", "Mic Bias"},
+
+So we have :-
+
+ Destination Widget <=== Path Name <=== Source Widget
+
+Or:-
+
+ Sink, Path, Source
+
+Or :-
+
+ "Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch".
+
+When there is no path name connecting widgets (e.g. a direct connection) we
+pass NULL for the path name.
+
+Interconnections are created with a call to:-
+
+snd_soc_dapm_connect_input(codec, sink, path, source);
+
+Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and
+interconnections have been registered with the core. This causes the core to
+scan the codec and machine so that the internal DAPM state matches the
+physical state of the machine.
+
+
+3.1 Machine Widget Interconnections
+-----------------------------------
+Machine widget interconnections are created in the same way as codec ones and
+directly connect the codec pins to machine level widgets.
+
+e.g. connects the speaker out codec pins to the internal speaker.
+
+ /* ext speaker connected to codec pins LOUT2, ROUT2 */
+ {"Ext Spk", NULL , "ROUT2"},
+ {"Ext Spk", NULL , "LOUT2"},
+
+This allows the DAPM to power on and off pins that are connected (and in use)
+and pins that are NC respectively.
+
+
+4 Endpoint Widgets
+===================
+An endpoint is a start or end point (widget) of an audio signal within the
+machine and includes the codec. e.g.
+
+ o Headphone Jack
+ o Internal Speaker
+ o Internal Mic
+ o Mic Jack
+ o Codec Pins
+
+When a codec pin is NC it can be marked as not used with a call to
+
+snd_soc_dapm_set_endpoint(codec, "Widget Name", 0);
+
+The last argument is 0 for inactive and 1 for active. This way the pin and its
+input widget will never be powered up and consume power.
+
+This also applies to machine widgets. e.g. if a headphone is connected to a
+jack then the jack can be marked active. If the headphone is removed, then
+the headphone jack can be marked inactive.
+
+
+5 DAPM Widget Events
+====================
+
+Some widgets can register their interest with the DAPM core in PM events.
+e.g. A Speaker with an amplifier registers a widget so the amplifier can be
+powered only when the spk is in use.
+
+/* turn speaker amplifier on/off depending on use */
+static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event)
+{
+ if (SND_SOC_DAPM_EVENT_ON(event))
+ set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
+ else
+ reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
+
+ return 0;
+}
+
+/* corgi machine dapm widgets */
+static const struct snd_soc_dapm_widget wm8731_dapm_widgets =
+ SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event);
+
+Please see soc-dapm.h for all other widgets that support events.
+
+
+5.1 Event types
+---------------
+
+The following event types are supported by event widgets.
+
+/* dapm event types */
+#define SND_SOC_DAPM_PRE_PMU 0x1 /* before widget power up */
+#define SND_SOC_DAPM_POST_PMU 0x2 /* after widget power up */
+#define SND_SOC_DAPM_PRE_PMD 0x4 /* before widget power down */
+#define SND_SOC_DAPM_POST_PMD 0x8 /* after widget power down */
+#define SND_SOC_DAPM_PRE_REG 0x10 /* before audio path setup */
+#define SND_SOC_DAPM_POST_REG 0x20 /* after audio path setup */

+ASoC Machine Driver
+===================
+
+The ASoC machine (or board) driver is the code that glues together the platform
+and codec drivers.
+
+The machine driver can contain codec and platform specific code. It registers
+the audio subsystem with the kernel as a platform device and is represented by
+the following struct:-
+
+/* SoC machine */
+struct snd_soc_machine {
+ char *name;
+
+ int (*probe)(struct platform_device *pdev);
+ int (*remove)(struct platform_device *pdev);
+
+ /* the pre and post PM functions are used to do any PM work before and
+ * after the codec and DAI's do any PM work. */
+ int (*suspend_pre)(struct platform_device *pdev, pm_message_t state);
+ int (*suspend_post)(struct platform_device *pdev, pm_message_t state);
+ int (*resume_pre)(struct platform_device *pdev);
+ int (*resume_post)(struct platform_device *pdev);
+
+ /* machine stream operations */
+ struct snd_soc_ops *ops;
+
+ /* CPU <--> Codec DAI links */
+ struct snd_soc_dai_link *dai_link;
+ int num_links;
+};
+
+probe()/remove()
+----------------
+probe/remove are optional. Do any machine specific probe here.
+
+
+suspend()/resume()
+------------------
+The machine driver has pre and post versions of suspend and resume to take care
+of any machine audio tasks that have to be done before or after the codec, DAI's
+and DMA is suspended and resumed. Optional.
+
+
+Machine operations
+------------------
+The machine specific audio operations can be set here. Again this is optional.
+
+
+Machine DAI Configuration
+-------------------------
+The machine DAI configuration glues all the codec and CPU DAI's together. It can
+also be used to set up the DAI system clock and for any machine related DAI
+initialisation e.g. the machine audio map can be connected to the codec audio
+map, unconnnected codec pins can be set as such. Please see corgi.c, spitz.c
+for examples.
+
+struct snd_soc_dai_link is used to set up each DAI in your machine. e.g.
+
+/* corgi digital audio interface glue - connects codec <--> CPU */
+static struct snd_soc_dai_link corgi_dai = {
+ .name = "WM8731",
+ .stream_name = "WM8731",
+ .cpu_dai = &pxa_i2s_dai,
+ .codec_dai = &wm8731_dai,
+ .init = corgi_wm8731_init,
+ .ops = &corgi_ops,
+};
+
+struct snd_soc_machine then sets up the machine with it's DAI's. e.g.
+
+/* corgi audio machine driver */
+static struct snd_soc_machine snd_soc_machine_corgi = {
+ .name = "Corgi",
+ .dai_link = &corgi_dai,
+ .num_links = 1,
+};
+
+
+Machine Audio Subsystem
+-----------------------
+
+The machine soc device glues the platform, machine and codec driver together.
+Private data can also be set here. e.g.
+
+/* corgi audio private data */
+static struct wm8731_setup_data corgi_wm8731_setup = {
+ .i2c_address = 0x1b,
+};
+
+/* corgi audio subsystem */
+static struct snd_soc_device corgi_snd_devdata = {
+ .machine = &snd_soc_machine_corgi,
+ .platform = &pxa2xx_soc_platform,
+ .codec_dev = &soc_codec_dev_wm8731,
+ .codec_data = &corgi_wm8731_setup,
+};
+
+
+Machine Power Map
+-----------------
+
+The machine driver can optionally extend the codec power map and to become an
+audio power map of the audio subsystem. This allows for automatic power up/down
+of speaker/HP amplifiers, etc. Codec pins can be connected to the machines jack
+sockets in the machine init function. See soc/pxa/spitz.c and dapm.txt for
+details.
+
+
+Machine Controls
+----------------
+
+Machine specific audio mixer controls can be added in the dai init function.

+ALSA SoC Layer
+==============
+
+The overall project goal of the ALSA System on Chip (ASoC) layer is to provide
+better ALSA support for embedded system on chip procesors (e.g. pxa2xx, au1x00,
+iMX, etc) and portable audio codecs. Currently there is some support in the
+kernel for SoC audio, however it has some limitations:-
+
+ * Currently, codec drivers are often tightly coupled to the underlying SoC
+ cpu. This is not ideal and leads to code duplication i.e. Linux now has 4
+ different wm8731 drivers for 4 different SoC platforms.
+
+ * There is no standard method to signal user initiated audio events.
+ e.g. Headphone/Mic insertion, Headphone/Mic detection after an insertion
+ event. These are quite common events on portable devices and ofter require
+ machine specific code to re route audio, enable amps etc after such an event.
+
+ * Current drivers tend to power up the entire codec when playing
+ (or recording) audio. This is fine for a PC, but tends to waste a lot of
+ power on portable devices. There is also no support for saving power via
+ changing codec oversampling rates, bias currents, etc.
+
+
+ASoC Design
+===========
+
+The ASoC layer is designed to address these issues and provide the following
+features :-
+
+ * Codec independence. Allows reuse of codec drivers on other platforms
+ and machines.
+
+ * Easy I2S/PCM audio interface setup between codec and SoC. Each SoC interface
+ and codec registers it's audio interface capabilities with the core and are
+ subsequently matched and configured when the application hw params are known.
+
+ * Dynamic Audio Power Management (DAPM). DAPM automatically sets the codec to
+ it's minimum power state at all times. This includes powering up/down
+ internal power blocks depending on the internal codec audio routing and any
+ active streams.
+
+ * Pop and click reduction. Pops and clicks can be reduced by powering the
+ codec up/down in the correct sequence (including using digital mute). ASoC
+ signals the codec when to change power states.
+
+ * Machine specific controls: Allow machines to add controls to the sound card
+ e.g. volume control for speaker amp.
+
+To achieve all this, ASoC basically splits an embedded audio system into 3
+components :-
+
+ * Codec driver: The codec driver is platform independent and contains audio
+ controls, audio interface capabilities, codec dapm definition and codec IO
+ functions.
+
+ * Platform driver: The platform driver contains the audio dma engine and audio
+ interface drivers (e.g. I2S, AC97, PCM) for that platform.
+
+ * Machine driver: The machine driver handles any machine specific controls and
+ audio events. i.e. turing on an amp at start of playback.
+

+ASoC Platform Driver
+====================
+
+An ASoC platform driver can be divided into audio DMA and SoC DAI configuration
+and control. The platform drivers only target the SoC CPU and must have no board
+specific code.
+
+Audio DMA
+=========
+
+The platform DMA driver optionally supports the following alsa operations:-
+
+/* SoC audio ops */
+struct snd_soc_ops {
+ int (*startup)(struct snd_pcm_substream *);
+ void (*shutdown)(struct snd_pcm_substream *);
+ int (*hw_params)(struct snd_pcm_substream *, struct snd_pcm_hw_params *);
+ int (*hw_free)(struct snd_pcm_substream *);
+ int (*prepare)(struct snd_pcm_substream *);
+ int (*trigger)(struct snd_pcm_substream *, int);
+};
+
+The platform driver exports it's DMA functionailty via struct snd_soc_platform:-
+
+struct snd_soc_platform {
+ char *name;
+
+ int (*probe)(struct platform_device *pdev);
+ int (*remove)(struct platform_device *pdev);
+ int (*suspend)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
+ int (*resume)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
+
+ /* pcm creation and destruction */
+ int (*pcm_new)(struct snd_card *, struct snd_soc_codec_dai *, struct snd_pcm *);
+ void (*pcm_free)(struct snd_pcm *);
+
+ /* platform stream ops */
+ struct snd_pcm_ops *pcm_ops;
+};
+
+Please refer to the alsa driver documentation for details of audio DMA.
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
+
+An example DMA driver is soc/pxa/pxa2xx-pcm.c
+
+
+SoC DAI Drivers
+===============
+
+Each SoC DAI driver must provide the following features:-
+
+ 1) Digital audio interface (DAI) description
+ 2) Digital audio interface configuration
+ 3) PCM's description
+ 4) Sysclk configuration
+ 5) Suspend and resume (optional)
+
+Please see codec.txt for a description of items 1 - 4.
--- /dev/null
+Audio Pops and Clicks
+=====================
+
+Pops and clicks are unwanted audio artifacts caused by the powering up and down
+of components within the audio subsystem. This is noticable on PC's when an
+audio module is either loaded or unloaded (at module load time the sound card is
+powered up and causes a popping noise on the speakers).
+
+Pops and clicks can be more frequent on portable systems with DAPM. This is
+because the components within the subsystem are being dynamically powered
+depending on the audio usage and this can subsequently cause a small pop or
+click every time a component power state is changed.
+
+
+Minimising Playback Pops and Clicks
+===================================
+
+Playback pops in portable audio subsystems cannot be completely eliminated atm,
+however future audio codec hardware will have better pop and click supression.
+Pops can be reduced within playback by powering the audio components in a
+specific order. This order is different for startup and shutdown and follows
+some basic rules:-
+
+ Startup Order :- DAC --> Mixers --> Output PGA --> Digital Unmute
+
+ Shutdown Order :- Digital Mute --> Output PGA --> Mixers --> DAC
+
+This assumes that the codec PCM output path from the DAC is via a mixer and then
+a PGA (programmable gain amplifier) before being output to the speakers.
+
+
+Minimising Capture Pops and Clicks
+==================================
+
+Capture artifacts are somewhat easier to get rid as we can delay activating the
+ADC until all the pops have occured. This follows similar power rules to
+playback in that components are powered in a sequence depending upon stream
+startup or shutdown.
+
+ Startup Order - Input PGA --> Mixers --> ADC
+
+ Shutdown Order - ADC --> Mixers --> Input PGA
+
+
+Zipper Noise
+============
+An unwanted zipper noise can occur within the audio playback or capture stream
+when a volume control is changed near its maximum gain value. The zipper noise
+is heard when the gain increase or decrease changes the mean audio signal
+amplitude too quickly. It can be minimised by enabling the zero cross setting
+for each volume control. The ZC forces the gain change to occur when the signal
+crosses the zero amplitude line.

- tristate "Advanced Power Management Emulation"
- ---help---
- APM is a BIOS specification for saving power using several different
- techniques. This is mostly useful for battery powered laptops with
- APM compliant BIOSes. If you say Y here, the system time will be
- reset after a RESUME operation, the /proc/apm device will provide
- battery status information, and user-space programs will receive
- notification of APM "events" (e.g. battery status change).
-
- In order to use APM, you will need supporting software. For location
- and more information, read <file:Documentation/pm.txt> and the
- Battery Powered Linux mini-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- This driver does not spin down disk drives (see the hdparm(8)
- manpage ("man 8 hdparm") for that), and it doesn't turn off
- VESA-compliant "green" monitors.
-
- Generally, if you don't have a battery in your machine, there isn't
- much point in using this driver and you should say N. If you get
- random kernel OOPSes or reboots that don't seem to be related to
- anything, try disabling/enabling this option (or disabling/enabling
- APM in your BIOS).

- ---help---
- APM is a BIOS specification for saving power using several different
- techniques. This is mostly useful for battery powered systems with
- APM compliant BIOSes. If you say Y here, the system time will be
- reset after a RESUME operation, the /proc/apm device will provide
- battery status information, and user-space programs will receive
- notification of APM "events" (e.g. battery status change).
-
- In order to use APM, you will need supporting software. For location
- and more information, read <file:Documentation/pm.txt> and the
- Battery Powered Linux mini-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- This driver does not spin down disk drives (see the hdparm(8)
- manpage ("man 8 hdparm") for that), and it doesn't turn off
- VESA-compliant "green" monitors.
-
- Generally, if you don't have a battery in your machine, there isn't
- much point in using this driver and you should say N. If you get
- random kernel OOPSes or reboots that don't seem to be related to
- anything, try disabling/enabling this option (or disabling/enabling
- APM in your BIOS).

+ default n
+ ---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.

-config IEEE1394_OUI_DB
- bool "OUI Database built-in (deprecated)"
- depends on IEEE1394
- help
- If you say Y here, then an OUI list (vendor unique ID's) will be
- compiled into the ieee1394 module. This doesn't really do much
- except being able to display the vendor of a hardware node. The
- downside is that it adds about 300k to the size of the module,
- or kernel (depending on whether you compile ieee1394 as a
- module, or static in the kernel).
-
- This option is not needed for userspace programs like gscanbus
- to show this information.

+
+ This driver can also be built as a module. If so, the module

+ help
+ APM is a BIOS specification for saving power using several different
+ techniques. This is mostly useful for battery powered laptops with
+ APM compliant BIOSes. If you say Y here, the system time will be
+ reset after a RESUME operation, the /proc/apm device will provide
+ battery status information, and user-space programs will receive
+ notification of APM "events" (e.g. battery status change).
+
+ In order to use APM, you will need supporting software. For location
+ and more information, read <file:Documentation/pm.txt> and the
+ Battery Powered Linux mini-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ This driver does not spin down disk drives (see the hdparm(8)
+ manpage ("man 8 hdparm") for that), and it doesn't turn off
+ VESA-compliant "green" monitors.
+
+ Generally, if you don't have a battery in your machine, there isn't
+ much point in using this driver and you should say N. If you get
+ random kernel OOPSes or reboots that don't seem to be related to
+ anything, try disabling/enabling this option (or disabling/enabling
+ APM in your BIOS).

The following two-column lookup table implements a part of the TCP throughput
equation from [RFC 3448, sec. 3.1]:
- s
+ s
X_calc = --------------------------------------------------------------
R * sqrt(2*b*p/3) + (3 * t_RTO * sqrt(3*b*p/8) * (p + 32*p^3))
s is the packet size in bytes
R is the round trip time in seconds
p is the loss event rate, between 0 and 1.0, of the number of loss
- events as a fraction of the number of packets transmitted
+ events as a fraction of the number of packets transmitted
t_RTO is the TCP retransmission timeout value in seconds
b is the number of packets acknowledged by a single TCP ACK
which we can break down into:
- s
+ s
X_calc = ---------
- R * f(p)
+ R * f(p)
where f(p) is given for 0 < p <= 1 by:
* the return result f(p)
The lookup table therefore actually tabulates the following function g(q):
- g(q) = 1000000 * f(q/1000000)
+ g(q) = 1000000 * f(q/1000000)
Hence, when p <= 1, q must be less than or equal to 1000000. To achieve finer
granularity for the practically more relevant case of small values of p (up to

Minor tweaks:
Cleaned up the code a little and added some pre-1.3.0 tweaks.
dev->hard_header/hard_header_len changed to use no headers.
Comments/bracketing tweaked.
Made the tunnels use dev->name not tunnel: when error reporting.
Added tx_dropped stat

-config IP_NF_TARGET_TCPMSS
- tristate "TCPMSS target support"
- depends on IP_NF_IPTABLES
- ---help---
- This option adds a `TCPMSS' target, which allows you to alter the
- MSS value of TCP SYN packets, to control the maximum size for that
- connection (usually limiting it to your outgoing interface's MTU
- minus 40).
-
- This is used to overcome criminally braindead ISPs or servers which
- block ICMP Fragmentation Needed packets. The symptoms of this
- problem are that everything works fine from your Linux
- firewall/router, but machines behind it can never exchange large
- packets:
- 1) Web browsers connect, then hang with no data received.
- 2) Small mail works fine, but large emails hang.
- 3) ssh works fine, but scp hangs after initial handshaking.
-
- Workaround: activate this option and add a rule to your firewall
- configuration like:
-
- iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
- -j TCPMSS --clamp-mss-to-pmtu
-
- To compile it as a module, choose M here. If unsure, say N.

+ ---help---
+ This option adds a `TCPMSS' target, which allows you to alter the
+ MSS value of TCP SYN packets, to control the maximum size for that
+ connection (usually limiting it to your outgoing interface's MTU
+ minus 40).
+
+ This is used to overcome criminally braindead ISPs or servers which
+ block ICMP Fragmentation Needed packets. The symptoms of this
+ problem are that everything works fine from your Linux
+ firewall/router, but machines behind it can never exchange large
+ packets:
+ 1) Web browsers connect, then hang with no data received.
+ 2) Small mail works fine, but large emails hang.
+ 3) ssh works fine, but scp hangs after initial handshaking.
+
+ Workaround: activate this option and add a rule to your firewall
+ configuration like:
+
+ iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
+ -j TCPMSS --clamp-mss-to-pmtu

+ * Revision history
+ * 12th Aug 2005 Initial version.
+ * 25th Oct 2005 Implemented path power domain.
+ * 18th Dec 2005 Implemented machine and stream level power domain.
+ *
+ * Features:
+ * o Changes power status of internal codec blocks depending on the
+ * dynamic configuration of codec internal audio paths and active
+ * DAC's/ADC's.
+ * o Platform power domain - can support external components i.e. amps and
+ * mic/meadphone insertion events.
+ * o Automatic Mic Bias support
+ * o Jack insertion power event initiation - e.g. hp insertion will enable
+ * sinks, dacs, etc
+ * o Delayed powerdown of audio susbsytem to reduce pops between a quick
+ * device reopen.
+ *
+ * Todo:
+ * o DAPM power change sequencing - allow for configurable per
+ * codec sequences.
+ * o Support for analogue bias optimisation.
+ * o Support for reduced codec oversampling rates.
+ * o Support for reduced codec bias currents.
