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).

They are provided from many kinds of chip, and are familiar +to Linux developers working with embedded and custom hardware. Each GPIO +represents a bit connected to a particular pin, or "ball" on Ball Grid Array +(BGA) packages. Board schematics show which external hardware connects to +which GPIOs. Drivers can be written generically, so that board setup code +passes such pin configuration data to drivers. + +System-on-Chip (SOC) processors heavily rely on GPIOs. In some cases, every +non-dedicated pin can be configured as a GPIO; and most chips have at least +several dozen of them. Programmable logic devices (like FPGAs) can easily +provide GPIOs; multifunction chips like power managers, and audio codecs +often have a few such pins to help with pin scarcity on SOCs; and there are +also "GPIO Expander" chips that connect using the I2C or SPI serial busses. +Most PC southbridges have a few dozen GPIO-capable pins (with only the BIOS +firmware knowing how they're used). + +The exact capabilities of GPIOs vary between systems. Common options: + + - Output values are writable (high=1, low=0). Some chips also have + options about how that value is driven, so that for example only one + value might be driven ... supporting "wire-OR" and similar schemes + for the other value. + + - Input values are likewise readable (1, 0). Some chips support readback + of pins configured as "output", which is very useful in such "wire-OR" + cases (to support bidirectional signaling). GPIO controllers may have + input de-glitch logic, sometimes with software controls. + + - Inputs can often be used as IRQ signals, often edge triggered but + sometimes level triggered. Such IRQs may be configurable as system + wakeup events, to wake the system from a low power state. + + - Usually a GPIO will be configurable as either input or output, as needed + by different product boards; single direction ones exist too. + + - Most GPIOs can be accessed while holding spinlocks, but those accessed + through a serial bus normally can't. Some systems support both types. + +On a given board each GPIO is used for one specific purpose like monitoring +MMC/SD card insertion/removal, detecting card writeprotect status, driving +a LED, configuring a transceiver, bitbanging a serial bus, poking a hardware +watchdog, sensing a switch, and so on. + + +GPIO conventions +================ +Note that this is called a "convention" because you don't need to do it this +way, and it's no crime if you don't. There **are** cases where portability +is not the main issue; GPIOs are often used for the kind of board-specific +glue logic that may even change between board revisions, and can't ever be +used on a board that's wired differently. Only least-common-denominator +functionality can be very portable. Other features are platform-specific, +and that can be critical for glue logic. + +Plus, this doesn't define an implementation framework, just an interface. +One platform might implement it as simple inline functions accessing chip +registers; another might implement it by delegating through abstractions +used for several very different kinds of GPIO controller. + +That said, if the convention is supported on their platform, drivers should +use it when possible: + + #include <asm/gpio.h> + +If you stick to this convention then it'll be easier for other developers to +see what your code is doing, and help maintain it. + + +Identifying GPIOs +----------------- +GPIOs are identified by unsigned integers in the range 0..MAX_INT. That +reserves "negative" numbers for other purposes like marking signals as +"not available on this board", or indicating faults. + +Platforms define how they use those integers, and usually #define symbols +for the GPIO lines so that board-specific setup code directly corresponds +to the relevant schematics. In contrast, drivers should only use GPIO +numbers passed to them from that setup code, using platform_data to hold +board-specific pin configuration data (along with other board specific +data they need). That avoids portability problems. + +So for example one platform uses numbers 32-159 for GPIOs; while another +uses numbers 0..63 with one set of GPIO controllers, 64-79 with another +type of GPIO controller, and on one particular board 80-95 with an FPGA. +The numbers need not be contiguous; either of those platforms could also +use numbers 2000-2063 to identify GPIOs in a bank of I2C GPIO expanders. + +Whether a platform supports multiple GPIO controllers is currently a +platform-specific implementation issue. + + +Using GPIOs +----------- +One of the first things to do with a GPIO, often in board setup code when +setting up a platform_device using the GPIO, is mark its direction: + + /* set as input or output, returning 0 or negative errno */ + int gpio_direction_input(unsigned gpio); + int gpio_direction_output(unsigned gpio); + +The return value is zero for success, else a negative errno. It should +be checked, since the get/set calls don't have error returns and since +misconfiguration is possible. (These calls could sleep.) + +Setting the direction can fail if the GPIO number is invalid, or when +that particular GPIO can't be used in that mode. It's generally a bad +idea to rely on boot firmware to have set the direction correctly, since +it probably wasn't validated to do more than boot Linux. (Similarly, +that board setup code probably needs to multiplex that pin as a GPIO, +and configure pullups/pulldowns appropriately.) + + +Spinlock-Safe GPIO access +------------------------- +Most GPIO controllers can be accessed with memory read/write instructions. +That doesn't need to sleep, and can safely be done from inside IRQ handlers. + +Use these calls to access such GPIOs: + + /* GPIO INPUT: return zero or nonzero */ + int gpio_get_value(unsigned gpio); + + /* GPIO OUTPUT */ + void gpio_set_value(unsigned gpio, int value); + +The values are boolean, zero for low, nonzero for high. When reading the +value of an output pin, the value returned should be what's seen on the +pin ... that won't always match the specified output value, because of +issues including wire-OR and output latencies. + +The get/set calls have no error returns because "invalid GPIO" should have +been reported earlier in gpio_set_direction(). However, note that not all +platforms can read the value of output pins; those that can't should always +return zero. Also, these calls will be ignored for GPIOs that can't safely +be accessed wihtout sleeping (see below). + +Platform-specific implementations are encouraged to optimise the two +calls to access the GPIO value in cases where the GPIO number (and for +output, value) are constant. It's normal for them to need only a couple +of instructions in such cases (reading or writing a hardware register), +and not to need spinlocks. Such optimized calls can make bitbanging +applications a lot more efficient (in both space and time) than spending +dozens of instructions on subroutine calls. + + +GPIO access that may sleep +-------------------------- +Some GPIO controllers must be accessed using message based busses like I2C +or SPI. Commands to read or write those GPIO values require waiting to +get to the head of a queue to transmit a command and get its response. +This requires sleeping, which can't be done from inside IRQ handlers. + +Platforms that support this type of GPIO distinguish them from other GPIOs +by returning nonzero from this call: + + int gpio_cansleep(unsigned gpio); + +To access such GPIOs, a different set of accessors is defined: + + /* GPIO INPUT: return zero or nonzero, might sleep */ + int gpio_get_value_cansleep(unsigned gpio); + + /* GPIO OUTPUT, might sleep */ + void gpio_set_value_cansleep(unsigned gpio, int value); + +Other than the fact that these calls might sleep, and will not be ignored +for GPIOs that can't be accessed from IRQ handlers, these calls act the +same as the spinlock-safe calls. + + +Claiming and Releasing GPIOs (OPTIONAL) +--------------------------------------- +To help catch system configuration errors, two calls are defined. +However, many platforms don't currently support this mechanism. + + /* request GPIO, returning 0 or negative errno. + * non-null labels may be useful for diagnostics. + */ + int gpio_request(unsigned gpio, const char *label); + + /* release previously-claimed GPIO */ + void gpio_free(unsigned gpio); + +Passing invalid GPIO numbers to gpio_request() will fail, as will requesting +GPIOs that have already been claimed with that call. The return value of +gpio_request() must be checked. (These calls could sleep.) + +These calls serve two basic purposes. One is marking the signals which +are actually in use as GPIOs, for better diagnostics; systems may have +several hundred potential GPIOs, but often only a dozen are used on any +given board. Another is to catch conflicts between drivers, reporting +errors when drivers wrongly think they have exclusive use of that signal. + +These two calls are optional because not not all current Linux platforms +offer such functionality in their GPIO support; a valid implementation +could return success for all gpio_request() calls. Unlike the other calls, +the state they represent doesn't normally match anything from a hardware +register; it's just a software bitmap which clearly is not necessary for +correct operation of hardware or (bug free) drivers. + +Note that requesting a GPIO does NOT cause it to be configured in any +way; it just marks that GPIO as in use. Separate code must handle any +pin setup (e.g. controlling which pin the GPIO uses, pullup/pulldown). + + +GPIOs mapped to IRQs +-------------------- +GPIO numbers are unsigned integers; so are IRQ numbers. These make up +two logically distinct namespaces (GPIO 0 need not use IRQ 0). You can +map between them using calls like: + + /* map GPIO numbers to IRQ numbers */ + int gpio_to_irq(unsigned gpio); + + /* map IRQ numbers to GPIO numbers */ + int irq_to_gpio(unsigned irq); + +Those return either the corresponding number in the other namespace, or +else a negative errno code if the mapping can't be done. (For example, +some GPIOs can't used as IRQs.) It is an unchecked error to use a GPIO +number that hasn't been marked as an input using gpio_set_direction(), or +to use an IRQ number that didn't originally come from gpio_to_irq(). + +These two mapping calls are expected to cost on the order of a single +addition or subtraction. They're not allowed to sleep. + +Non-error values returned from gpio_to_irq() can be passed to request_irq() +or free_irq(). They will often be stored into IRQ resources for platform +devices, by the board-specific initialization code. Note that IRQ trigger +options are part of the IRQ interface, e.g. IRQF_TRIGGER_FALLING, as are +system wakeup capabilities. + +Non-error values returned from irq_to_gpio() would most commonly be used +with gpio_get_value(). + + + +What do these conventions omit? +=============================== +One of the biggest things these conventions omit is pin multiplexing, since +this is highly chip-specific and nonportable. One platform might not need +explicit multiplexing; another might have just two options for use of any +given pin; another might have eight options per pin; another might be able +to route a given GPIO to any one of several pins. (Yes, those examples all +come from systems that run Linux today.) + +Related to multiplexing is configuration and enabling of the pullups or +pulldowns integrated on some platforms. Not all platforms support them, +or support them in the same way; and any given board might use external +pullups (or pulldowns) so that the on-chip ones should not be used. + +There are other system-specific mechanisms that are not specified here, +like the aforementioned options for input de-glitching and wire-OR output. +Hardware may support reading or writing GPIOs in gangs, but that's usually +configuration dependednt: for GPIOs sharing the same bank. (GPIOs are +commonly grouped in banks of 16 or 32, with a given SOC having several such +banks.) Code relying on such mechanisms will necessarily be nonportable. + +Dynamic definition of GPIOs is not currently supported; for example, as +a side effect of configuring an add-on board with some GPIO expanders. + +These calls are purely for kernel space, but a userspace API could be built +on top of it. diff --git a/Documentation/ioctl-number.txt b/Documentation/ioctl-number.txt index 5a8bd5bd88ef..8f750c0efed5 100644 --- a/Documentation/ioctl-number.txt +++ b/Documentation/ioctl-number.txt @@ -94,8 +94,7 @@ Code Seq# Include File Comments 'L' 00-1F linux/loop.h 'L' E0-FF linux/ppdd.h encrypted disk device driver <http://linux01.gwdg.de/~alatham/ppdd.html> -'M' all linux/soundcard.h conflict! -'M' 00-1F linux/isicom.h conflict! +'M' all linux/soundcard.h 'N' 00-1F drivers/usb/scanner.h 'P' all linux/soundcard.h 'Q' all linux/soundcard.h diff --git a/Documentation/isdn/README.gigaset b/Documentation/isdn/README.gigaset index fa0d4cca964a..55b2852904a4 100644 --- a/Documentation/isdn/README.gigaset +++ b/Documentation/isdn/README.gigaset @@ -8,29 +8,33 @@ GigaSet 307x Device Driver This release supports the connection of the Gigaset 307x/417x family of ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB connection.

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.

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.
