The problem is that SCSI midlayer +request dispatch function is not atomic. It releases queue lock and +switch to SCSI host lock during issue and it's possible and likely to +happen in time that requests change their relative positions. Once +this problem is solved, TAG ordering can be enabled. + +* Currently, no matter which ordered mode is used, there can be only +one barrier request in progress. All I/O barriers are held off by +block layer until the previous I/O barrier is complete. This doesn't +make any difference for DRAIN ordered devices, but, for TAG ordered +devices with very high command latency, passing multiple I/O barriers +to low level *might* be helpful if they are very frequent. Well, this +certainly is a non-issue. I'm writing this just to make clear that no +two I/O barrier is ever passed to low-level driver. + +* Completion order. Requests in ordered sequence are issued in order +but not required to finish in order. Barrier implementation can +handle out-of-order completion of ordered sequence. IOW, the requests +MUST be processed in order but the hardware/software completion paths +are allowed to reorder completion notifications - eg. current SCSI +midlayer doesn't preserve completion order during error handling. + +* Requeueing order. Low-level drivers are free to requeue any request +after they removed it from the request queue with +blkdev_dequeue_request(). As barrier sequence should be kept in order +when requeued, generic elevator code takes care of putting requests in +order around barrier. See blk_ordered_req_seq() and +ELEVATOR_INSERT_REQUEUE handling in __elv_add_request() for details. + +Note that block drivers must not requeue preceding requests while +completing latter requests in an ordered sequence. Currently, no +error checking is done against this. + +* Error handling. Currently, block layer will report error to upper +layer if any of requests in an ordered sequence fails. Unfortunately, +this doesn't seem to be enough.

Consider the following sequence. + + i. Requests [0] ~ [post] leaves the request queue and enters + low-level driver. + ii. After a while, unfortunately, something goes wrong and the + drive fails [2]. Note that any of [0], [1] and [3] could have + completed by this time, but [pre] couldn't have been finished + as the drive must process it in order and it failed before + processing that command. + iii. Error handling kicks in and determines that the error is + unrecoverable and fails [2], and resumes operation. + iv. [pre] [barrier] [post] gets processed. + v. *BOOM* power fails + +The problem here is that the barrier request is *supposed* to indicate +that filesystem update requests [2] and [3] made it safely to the +physical medium and, if the machine crashes after the barrier is +written, filesystem recovery code can depend on that. Sadly, that +isn't true in this case anymore. IOW, the success of a I/O barrier +should also be dependent on success of some of the preceding requests, +where only upper layer (filesystem) knows what 'some' is. + +This can be solved by implementing a way to tell the block layer which +requests affect the success of the following barrier request and +making lower lever drivers to resume operation on error only after +block layer tells it to do so. + +As the probability of this happening is very low and the drive should +be faulty, implementing the fix is probably an overkill. But, still, +it's there. + +* In previous drafts of barrier implementation, there was fallback +mechanism such that, if FUA or ordered TAG fails, less fancy ordered +mode can be selected and the failed barrier request is retried +automatically. The rationale for this feature was that as FUA is +pretty new in ATA world and ordered tag was never used widely, there +could be devices which report to support those features but choke when +actually given such requests. + + This was removed for two reasons 1. it's an overkill 2. it's +impossible to implement properly when TAG ordering is used as low +level drivers resume after an error automatically. If it's ever +needed adding it back and modifying low level drivers accordingly +shouldn't be difficult. diff --git a/trunk/Documentation/cachetlb.txt b/trunk/Documentation/cachetlb.txt index 7eb715e07eda..4ae418889b88 100644 --- a/trunk/Documentation/cachetlb.txt +++ b/trunk/Documentation/cachetlb.txt @@ -136,7 +136,7 @@ changes occur: 8) void lazy_mmu_prot_update(pte_t pte) This interface is called whenever the protection on any user PTEs change.

There can +be multiple csrows and two channels. + +Memory controllers allow for several csrows, with 8 csrows being a typical value. +Yet, the actual number of csrows depends on the electrical "loading" +of a given motherboard, memory controller and DIMM characteristics. + +Dual channels allows for 128 bit data transfers to the CPU from memory. + + + Channel 0 Channel 1 + =================================== + csrow0 | DIMM_A0 | DIMM_B0 | + csrow1 | DIMM_A0 | DIMM_B0 | + =================================== + + =================================== + csrow2 | DIMM_A1 | DIMM_B1 | + csrow3 | DIMM_A1 | DIMM_B1 | + =================================== + +In the above example table there are 4 physical slots on the motherboard +for memory DIMMs: + + DIMM_A0 + DIMM_B0 + DIMM_A1 + DIMM_B1 + +Labels for these slots are usually silk screened on the motherboard. Slots +labeled 'A' are channel 0 in this example. Slots labled 'B' +are channel 1. Notice that there are two csrows possible on a +physical DIMM. These csrows are allocated their csrow assignment +based on the slot into which the memory DIMM is placed. Thus, when 1 DIMM +is placed in each Channel, the csrows cross both DIMMs. + +Memory DIMMs come single or dual "ranked". A rank is a populated csrow. +Thus, 2 single ranked DIMMs, placed in slots DIMM_A0 and DIMM_B0 above +will have 1 csrow, csrow0. csrow1 will be empty. On the other hand, +when 2 dual ranked DIMMs are similiaryly placed, then both csrow0 and +csrow1 will be populated. The pattern repeats itself for csrow2 and +csrow3. + +The representation of the above is reflected in the directory tree +in EDAC's sysfs interface. Starting in directory +/sys/devices/system/edac/mc each memory controller will be represented +by its own 'mcX' directory, where 'X" is the index of the MC. + + + ..../edac/mc/ + | + |->mc0 + |->mc1 + |->mc2 + .... + +Under each 'mcX' directory each 'csrowX' is again represented by a +'csrowX', where 'X" is the csrow index: + + + .../mc/mc0/ + | + |->csrow0 + |->csrow2 + |->csrow3 + .... + +Notice that there is no csrow1, which indicates that csrow0 is +composed of a single ranked DIMMs. This should also apply in both +Channels, in order to have dual-channel mode be operational. Since +both csrow2 and csrow3 are populated, this indicates a dual ranked +set of DIMMs for channels 0 and 1. + + +Within each of the 'mc','mcX' and 'csrowX' directories are several +EDAC control and attribute files. + + +============================================================================ +DIRECTORY 'mc' + +In directory 'mc' are EDAC system overall control and attribute files: + + +Panic on UE control file: + + 'panic_on_ue' + + An uncorrectable error will cause a machine panic.

The +legacy iSeries platform breaks those rules as it predates this scheme, +but no new board support will be accepted in the main tree that +doesn't follows them properly. In addition, since the advent of the +arch/powerpc merged architecture for ppc32 and ppc64, new 32-bit +platforms and 32-bit platforms which move into arch/powerpc will be +required to use these rules as well. + +The main requirement that will be defined in more detail below is +the presence of a device-tree whose format is defined after Open +Firmware specification. However, in order to make life easier +to embedded board vendors, the kernel doesn't require the device-tree +to represent every device in the system and only requires some nodes +and properties to be present. This will be described in detail in +section III, but, for example, the kernel does not require you to +create a node for every PCI device in the system. It is a requirement +to have a node for PCI host bridges in order to provide interrupt +routing informations and memory/IO ranges, among others. It is also +recommended to define nodes for on chip devices and other busses that +don't specifically fit in an existing OF specification. This creates a +great flexibility in the way the kernel can then probe those and match +drivers to device, without having to hard code all sorts of tables. It +also makes it more flexible for board vendors to do minor hardware +upgrades without significantly impacting the kernel code or cluttering +it with special cases. + + +1) Entry point for arch/powerpc +------------------------------- + + There is one and one single entry point to the kernel, at the start + of the kernel image. That entry point supports two calling + conventions: + + a) Boot from Open Firmware. If your firmware is compatible + with Open Firmware (IEEE 1275) or provides an OF compatible + client interface API (support for "interpret" callback of + forth words isn't required), you can enter the kernel with: + + r5 : OF callback pointer as defined by IEEE 1275 + bindings to powerpc. Only the 32 bit client interface + is currently supported + + r3, r4 : address & length of an initrd if any or 0 + + The MMU is either on or off; the kernel will run the + trampoline located in arch/powerpc/kernel/prom_init.c to + extract the device-tree and other information from open + firmware and build a flattened device-tree as described + in b). prom_init() will then re-enter the kernel using + the second method. This trampoline code runs in the + context of the firmware, which is supposed to handle all + exceptions during that time. + + b) Direct entry with a flattened device-tree block. This entry + point is called by a) after the OF trampoline and can also be + called directly by a bootloader that does not support the Open + Firmware client interface. It is also used by "kexec" to + implement "hot" booting of a new kernel from a previous + running one. This method is what I will describe in more + details in this document, as method a) is simply standard Open + Firmware, and thus should be implemented according to the + various standard documents defining it and its binding to the + PowerPC platform. The entry point definition then becomes: + + r3 : physical pointer to the device-tree block + (defined in chapter II) in RAM + + r4 : physical pointer to the kernel itself. This is + used by the assembly code to properly disable the MMU + in case you are entering the kernel with MMU enabled + and a non-1:1 mapping. + + r5 : NULL (as to differenciate with method a) + + Note about SMP entry: Either your firmware puts your other + CPUs in some sleep loop or spin loop in ROM where you can get + them out via a soft reset or some other means, in which case + you don't need to care, or you'll have to enter the kernel + with all CPUs. The way to do that with method b) will be + described in a later revision of this document. + + +2) Board support +---------------- + +64-bit kernels: + + Board supports (platforms) are not exclusive config options. An + arbitrary set of board supports can be built in a single kernel + image. The kernel will "know" what set of functions to use for a + given platform based on the content of the device-tree. Thus, you + should: + + a) add your platform support as a _boolean_ option in + arch/powerpc/Kconfig, following the example of PPC_PSERIES, + PPC_PMAC and PPC_MAPLE. The later is probably a good + example of a board support to start from. + + b) create your main platform file as + "arch/powerpc/platforms/myplatform/myboard_setup.c" and add it + to the Makefile under the condition of your CONFIG_ + option. This file will define a structure of type "ppc_md" + containing the various callbacks that the generic code will + use to get to your platform specific code + + c) Add a reference to your "ppc_md" structure in the + "machines" table in arch/powerpc/kernel/setup_64.c if you are + a 64-bit platform. + + d) request and get assigned a platform number (see PLATFORM_* + constants in include/asm-powerpc/processor.h + +32-bit embedded kernels: + + Currently, board support is essentially an exclusive config option. + The kernel is configured for a single platform. Part of the reason + for this is to keep kernels on embedded systems small and efficient; + part of this is due to the fact the code is already that way. In the + future, a kernel may support multiple platforms, but only if the + platforms feature the same core architectire. A single kernel build + cannot support both configurations with Book E and configurations + with classic Powerpc architectures. + + 32-bit embedded platforms that are moved into arch/powerpc using a + flattened device tree should adopt the merged tree practice of + setting ppc_md up dynamically, even though the kernel is currently + built with support for only a single platform at a time. This allows + unification of the setup code, and will make it easier to go to a + multiple-platform-support model in the future. + +NOTE: I believe the above will be true once Ben's done with the merge +of the boot sequences.... someone speak up if this is wrong! + + To add a 32-bit embedded platform support, follow the instructions + for 64-bit platforms above, with the exception that the Kconfig + option should be set up such that the kernel builds exclusively for + the platform selected. The processor type for the platform should + enable another config option to select the specific board + supported. + +NOTE: If ben doesn't merge the setup files, may need to change this to +point to setup_32.c + + + I will describe later the boot process and various callbacks that + your platform should implement. + + +II - The DT block format +======================== + + +This chapter defines the actual format of the flattened device-tree +passed to the kernel. The actual content of it and kernel requirements +are described later. You can find example of code manipulating that +format in various places, including arch/powerpc/kernel/prom_init.c +which will generate a flattened device-tree from the Open Firmware +representation, or the fs2dt utility which is part of the kexec tools +which will generate one from a filesystem representation. It is +expected that a bootloader like uboot provides a bit more support, +that will be discussed later as well. + +Note: The block has to be in main memory. It has to be accessible in +both real mode and virtual mode with no mapping other than main +memory. If you are writing a simple flash bootloader, it should copy +the block to RAM before passing it to the kernel. + + +1) Header +--------- + + The kernel is entered with r3 pointing to an area of memory that is + roughtly described in include/asm-powerpc/prom.h by the structure + boot_param_header: + +struct boot_param_header { + u32 magic; /* magic word OF_DT_HEADER */ + u32 totalsize; /* total size of DT block */ + u32 off_dt_struct; /* offset to structure */ + u32 off_dt_strings; /* offset to strings */ + u32 off_mem_rsvmap; /* offset to memory reserve map +*/ + u32 version; /* format version */ + u32 last_comp_version; /* last compatible version */ + + /* version 2 fields below */ + u32 boot_cpuid_phys; /* Which physical CPU id we're + booting on */ + /* version 3 fields below */ + u32 size_dt_strings; /* size of the strings block */ +}; + + Along with the constants: + +/* Definitions used by the flattened device tree */ +#define OF_DT_HEADER 0xd00dfeed /* 4: version, + 4: total size */ +#define OF_DT_BEGIN_NODE 0x1 /* Start node: full name +*/ +#define OF_DT_END_NODE 0x2 /* End node */ +#define OF_DT_PROP 0x3 /* Property: name off, + size, content */ +#define OF_DT_END 0x9 + + All values in this header are in big endian format, the various + fields in this header are defined more precisely below. All + "offset" values are in bytes from the start of the header; that is + from the value of r3. + + - magic + + This is a magic value that "marks" the beginning of the + device-tree block header. It contains the value 0xd00dfeed and is + defined by the constant OF_DT_HEADER + + - totalsize + + This is the total size of the DT block including the header. The + "DT" block should enclose all data structures defined in this + chapter (who are pointed to by offsets in this header). That is, + the device-tree structure, strings, and the memory reserve map. + + - off_dt_struct + + This is an offset from the beginning of the header to the start + of the "structure" part the device tree. (see 2) device tree) + + - off_dt_strings + + This is an offset from the beginning of the header to the start + of the "strings" part of the device-tree + + - off_mem_rsvmap + + This is an offset from the beginning of the header to the start + of the reserved memory map. This map is a list of pairs of 64 + bit integers. Each pair is a physical address and a size. The + + list is terminated by an entry of size 0. This map provides the + kernel with a list of physical memory areas that are "reserved" + and thus not to be used for memory allocations, especially during + early initialization. The kernel needs to allocate memory during + boot for things like un-flattening the device-tree, allocating an + MMU hash table, etc... Those allocations must be done in such a + way to avoid overriding critical things like, on Open Firmware + capable machines, the RTAS instance, or on some pSeries, the TCE + tables used for the iommu. Typically, the reserve map should + contain _at least_ this DT block itself (header,total_size). If + you are passing an initrd to the kernel, you should reserve it as + well. You do not need to reserve the kernel image itself. The map + should be 64 bit aligned. + + - version + + This is the version of this structure. Version 1 stops + here. Version 2 adds an additional field boot_cpuid_phys. + Version 3 adds the size of the strings block, allowing the kernel + to reallocate it easily at boot and free up the unused flattened + structure after expansion. Version 16 introduces a new more + "compact" format for the tree itself that is however not backward + compatible. You should always generate a structure of the highest + version defined at the time of your implementation. Currently + that is version 16, unless you explicitely aim at being backward + compatible. + + - last_comp_version + + Last compatible version. This indicates down to what version of + the DT block you are backward compatible. For example, version 2 + is backward compatible with version 1 (that is, a kernel build + for version 1 will be able to boot with a version 2 format). You + should put a 1 in this field if you generate a device tree of + version 1 to 3, or 0x10 if you generate a tree of version 0x10 + using the new unit name format. + + - boot_cpuid_phys + + This field only exist on version 2 headers. It indicate which + physical CPU ID is calling the kernel entry point. This is used, + among others, by kexec. If you are on an SMP system, this value + should match the content of the "reg" property of the CPU node in + the device-tree corresponding to the CPU calling the kernel entry + point (see further chapters for more informations on the required + device-tree contents) + + + So the typical layout of a DT block (though the various parts don't + need to be in that order) looks like this (addresses go from top to + bottom): + + + ------------------------------ + r3 -> | struct boot_param_header | + ------------------------------ + | (alignment gap) (*) | + ------------------------------ + | memory reserve map | + ------------------------------ + | (alignment gap) | + ------------------------------ + | | + | device-tree structure | + | | + ------------------------------ + | (alignment gap) | + ------------------------------ + | | + | device-tree strings | + | | + -----> ------------------------------ + | + | + --- (r3 + totalsize) + + (*) The alignment gaps are not necessarily present; their presence + and size are dependent on the various alignment requirements of + the individual data blocks. + + +2) Device tree generalities +--------------------------- + +This device-tree itself is separated in two different blocks, a +structure block and a strings block. Both need to be aligned to a 4 +byte boundary. + +First, let's quickly describe the device-tree concept before detailing +the storage format. This chapter does _not_ describe the detail of the +required types of nodes & properties for the kernel, this is done +later in chapter III. + +The device-tree layout is strongly inherited from the definition of +the Open Firmware IEEE 1275 device-tree. It's basically a tree of +nodes, each node having two or more named properties. A property can +have a value or not. + +It is a tree, so each node has one and only one parent except for the +root node who has no parent. + +A node has 2 names. The actual node name is generally contained in a +property of type "name" in the node property list whose value is a +zero terminated string and is mandatory for version 1 to 3 of the +format definition (as it is in Open Firmware). Version 0x10 makes it +optional as it can generate it from the unit name defined below. + +There is also a "unit name" that is used to differenciate nodes with +the same name at the same level, it is usually made of the node +name's, the "@" sign, and a "unit address", which definition is +specific to the bus type the node sits on. + +The unit name doesn't exist as a property per-se but is included in +the device-tree structure. It is typically used to represent "path" in +the device-tree. More details about the actual format of these will be +below. + +The kernel powerpc generic code does not make any formal use of the +unit address (though some board support code may do) so the only real +requirement here for the unit address is to ensure uniqueness of +the node unit name at a given level of the tree. Nodes with no notion +of address and no possible sibling of the same name (like /memory or +/cpus) may omit the unit address in the context of this specification, +or use the "@0" default unit address. The unit name is used to define +a node "full path", which is the concatenation of all parent node +unit names separated with "/". + +The root node doesn't have a defined name, and isn't required to have +a name property either if you are using version 3 or earlier of the +format. It also has no unit address (no @ symbol followed by a unit +address). The root node unit name is thus an empty string. The full +path to the root node is "/". + +Every node which actually represents an actual device (that is, a node +which isn't only a virtual "container" for more nodes, like "/cpus" +is) is also required to have a "device_type" property indicating the +type of node . + +Finally, every node that can be referenced from a property in another +node is required to have a "linux,phandle" property. Real open +firmware implementations provide a unique "phandle" value for every +node that the "prom_init()" trampoline code turns into +"linux,phandle" properties. However, this is made optional if the +flattened device tree is used directly. An example of a node +referencing another node via "phandle" is when laying out the +interrupt tree which will be described in a further version of this +document. + +This "linux, phandle" property is a 32 bit value that uniquely +identifies a node. You are free to use whatever values or system of +values, internal pointers, or whatever to generate these, the only +requirement is that every node for which you provide that property has +a unique value for it. + +Here is an example of a simple device-tree. In this example, an "o" +designates a node followed by the node unit name. Properties are +presented with their name followed by their content. "content" +represents an ASCII string (zero terminated) value, while +represents a 32 bit hexadecimal value. The various nodes in this +example will be discussed in a later chapter. At this point, it is +only meant to give you a idea of what a device-tree looks like. I have +purposefully kept the "name" and "linux,phandle" properties which +aren't necessary in order to give you a better idea of what the tree +looks like in practice. + + / o device-tree + |- name = "device-tree" + |- model = "MyBoardName" + |- compatible = "MyBoardFamilyName" + |- #address-cells = <2> + |- #size-cells = <2> + |- linux,phandle = <0> + | + o cpus + | | - name = "cpus" + | | - linux,phandle = <1> + | | - #address-cells = <1> + | | - #size-cells = <0> + | | + | o PowerPC,970@0 + | |- name = "PowerPC,970" + | |- device_type = "cpu" + | |- reg = <0> + | |- clock-frequency = <5f5e1000> + | |- linux,boot-cpu + | |- linux,phandle = <2> + | + o memory@0 + | |- name = "memory" + | |- device_type = "memory" + | |- reg = <00000000 00000000 00000000 20000000> + | |- linux,phandle = <3> + | + o chosen + |- name = "chosen" + |- bootargs = "root=/dev/sda2" + |- linux,platform = <00000600> + |- linux,phandle = <4> + +This tree is almost a minimal tree. It pretty much contains the +minimal set of required nodes and properties to boot a linux kernel; +that is, some basic model informations at the root, the CPUs, and the +physical memory layout. It also includes misc information passed +through /chosen, like in this example, the platform type (mandatory) +and the kernel command line arguments (optional). + +The /cpus/PowerPC,970@0/linux,boot-cpu property is an example of a +property without a value. All other properties have a value. The +significance of the #address-cells and #size-cells properties will be +explained in chapter IV which defines precisely the required nodes and +properties and their content. + + +3) Device tree "structure" block + +The structure of the device tree is a linearized tree structure. The +"OF_DT_BEGIN_NODE" token starts a new node, and the "OF_DT_END_NODE" +ends that node definition. Child nodes are simply defined before +"OF_DT_END_NODE" (that is nodes within the node). A 'token' is a 32 +bit value. The tree has to be "finished" with a OF_DT_END token + +Here's the basic structure of a single node: + + * token OF_DT_BEGIN_NODE (that is 0x00000001) + * for version 1 to 3, this is the node full path as a zero + terminated string, starting with "/". For version 16 and later, + this is the node unit name only (or an empty string for the + root node) + * [align gap to next 4 bytes boundary] + * for each property: + * token OF_DT_PROP (that is 0x00000003) + * 32 bit value of property value size in bytes (or 0 of no + * value) + * 32 bit value of offset in string block of property name + * property value data if any + * [align gap to next 4 bytes boundary] + * [child nodes if any] + * token OF_DT_END_NODE (that is 0x00000002) + +So the node content can be summmarised as a start token, a full path, +a list of properties, a list of child node and an end token. Every +child node is a full node structure itself as defined above. + +4) Device tree 'strings" block + +In order to save space, property names, which are generally redundant, +are stored separately in the "strings" block. This block is simply the +whole bunch of zero terminated strings for all property names +concatenated together. The device-tree property definitions in the +structure block will contain offset values from the beginning of the +strings block. + + +III - Required content of the device tree +========================================= + +WARNING: All "linux,*" properties defined in this document apply only +to a flattened device-tree. If your platform uses a real +implementation of Open Firmware or an implementation compatible with +the Open Firmware client interface, those properties will be created +by the trampoline code in the kernel's prom_init() file. For example, +that's where you'll have to add code to detect your board model and +set the platform number. However, when using the flatenned device-tree +entry point, there is no prom_init() pass, and thus you have to +provide those properties yourself. + + +1) Note about cells and address representation +---------------------------------------------- + +The general rule is documented in the various Open Firmware +documentations. If you chose to describe a bus with the device-tree +and there exist an OF bus binding, then you should follow the +specification. However, the kernel does not require every single +device or bus to be described by the device tree. + +In general, the format of an address for a device is defined by the +parent bus type, based on the #address-cells and #size-cells +property. In the absence of such a property, the parent's parent +values are used, etc... The kernel requires the root node to have +those properties defining addresses format for devices directly mapped +on the processor bus. + +Those 2 properties define 'cells' for representing an address and a +size. A "cell" is a 32 bit number. For example, if both contain 2 +like the example tree given above, then an address and a size are both +composed of 2 cells, and each is a 64 bit number (cells are +concatenated and expected to be in big endian format). Another example +is the way Apple firmware defines them, with 2 cells for an address +and one cell for a size. Most 32-bit implementations should define +#address-cells and #size-cells to 1, which represents a 32-bit value. +Some 32-bit processors allow for physical addresses greater than 32 +bits; these processors should define #address-cells as 2. + +"reg" properties are always a tuple of the type "address size" where +the number of cells of address and size is specified by the bus +#address-cells and #size-cells. When a bus supports various address +spaces and other flags relative to a given address allocation (like +prefetchable, etc...) those flags are usually added to the top level +bits of the physical address. For example, a PCI physical address is +made of 3 cells, the bottom two containing the actual address itself +while the top cell contains address space indication, flags, and pci +bus & device numbers. + +For busses that support dynamic allocation, it's the accepted practice +to then not provide the address in "reg" (keep it 0) though while +providing a flag indicating the address is dynamically allocated, and +then, to provide a separate "assigned-addresses" property that +contains the fully allocated addresses. See the PCI OF bindings for +details. + +In general, a simple bus with no address space bits and no dynamic +allocation is preferred if it reflects your hardware, as the existing +kernel address parsing functions will work out of the box. If you +define a bus type with a more complex address format, including things +like address space bits, you'll have to add a bus translator to the +prom_parse.c file of the recent kernels for your bus type. + +The "reg" property only defines addresses and sizes (if #size-cells +is +non-0) within a given bus. In order to translate addresses upward +(that is into parent bus addresses, and possibly into cpu physical +addresses), all busses must contain a "ranges" property. If the +"ranges" property is missing at a given level, it's assumed that +translation isn't possible. The format of the "ranges" proprety for a +bus is a list of: + + bus address, parent bus address, size + +"bus address" is in the format of the bus this bus node is defining, +that is, for a PCI bridge, it would be a PCI address. Thus, (bus +address, size) defines a range of addresses for child devices. "parent +bus address" is in the format of the parent bus of this bus. For +example, for a PCI host controller, that would be a CPU address. For a +PCI<->ISA bridge, that would be a PCI address. It defines the base +address in the parent bus where the beginning of that range is mapped. + +For a new 64 bit powerpc board, I recommend either the 2/2 format or +Apple's 2/1 format which is slightly more compact since sizes usually +fit in a single 32 bit word. New 32 bit powerpc boards should use a +1/1 format, unless the processor supports physical addresses greater +than 32-bits, in which case a 2/1 format is recommended. + + +2) Note about "compatible" properties +------------------------------------- + +These properties are optional, but recommended in devices and the root +node. The format of a "compatible" property is a list of concatenated +zero terminated strings. They allow a device to express its +compatibility with a family of similar devices, in some cases, +allowing a single driver to match against several devices regardless +of their actual names. + +3) Note about "name" properties +------------------------------- + +While earlier users of Open Firmware like OldWorld macintoshes tended +to use the actual device name for the "name" property, it's nowadays +considered a good practice to use a name that is closer to the device +class (often equal to device_type). For example, nowadays, ethernet +controllers are named "ethernet", an additional "model" property +defining precisely the chip type/model, and "compatible" property +defining the family in case a single driver can driver more than one +of these chips. However, the kernel doesn't generally put any +restriction on the "name" property; it is simply considered good +practice to follow the standard and its evolutions as closely as +possible. + +Note also that the new format version 16 makes the "name" property +optional. If it's absent for a node, then the node's unit name is then +used to reconstruct the name. That is, the part of the unit name +before the "@" sign is used (or the entire unit name if no "@" sign +is present). + +4) Note about node and property names and character set +------------------------------------------------------- + +While open firmware provides more flexibe usage of 8859-1, this +specification enforces more strict rules. Nodes and properties should +be comprised only of ASCII characters 'a' to 'z', '0' to +'9', ',', '.', '_', '+', '#', '?', and '-'. Node names additionally +allow uppercase characters 'A' to 'Z' (property names should be +lowercase. The fact that vendors like Apple don't respect this rule is +irrelevant here). Additionally, node and property names should always +begin with a character in the range 'a' to 'z' (or 'A' to 'Z' for node +names). + +The maximum number of characters for both nodes and property names +is 31. In the case of node names, this is only the leftmost part of +a unit name (the pure "name" property), it doesn't include the unit +address which can extend beyond that limit. + + +5) Required nodes and properties +-------------------------------- + These are all that are currently required. However, it is strongly + recommended that you expose PCI host bridges as documented in the + PCI binding to open firmware, and your interrupt tree as documented + in OF interrupt tree specification. + + a) The root node + + The root node requires some properties to be present: + + - model : this is your board name/model + - #address-cells : address representation for "root" devices + - #size-cells: the size representation for "root" devices + + Additionally, some recommended properties are: + + - compatible : the board "family" generally finds its way here, + for example, if you have 2 board models with a similar layout, + that typically get driven by the same platform code in the + kernel, you would use a different "model" property but put a + value in "compatible". The kernel doesn't directly use that + value (see /chosen/linux,platform for how the kernel choses a + platform type) but it is generally useful. + + The root node is also generally where you add additional properties + specific to your board like the serial number if any, that sort of + thing. it is recommended that if you add any "custom" property whose + name may clash with standard defined ones, you prefix them with your + vendor name and a comma. + + b) The /cpus node + + This node is the parent of all individual CPU nodes. It doesn't + have any specific requirements, though it's generally good practice + to have at least: + + #address-cells = <00000001> + #size-cells = <00000000> + + This defines that the "address" for a CPU is a single cell, and has + no meaningful size. This is not necessary but the kernel will assume + that format when reading the "reg" properties of a CPU node, see + below + + c) The /cpus/* nodes + + So under /cpus, you are supposed to create a node for every CPU on + the machine. There is no specific restriction on the name of the + CPU, though It's common practice to call it PowerPC,. For + example, Apple uses PowerPC,G5 while IBM uses PowerPC,970FX. + + Required properties: + + - device_type : has to be "cpu" + - reg : This is the physical cpu number, it's a single 32 bit cell + and is also used as-is as the unit number for constructing the + unit name in the full path. For example, with 2 CPUs, you would + have the full path: + /cpus/PowerPC,970FX@0 + /cpus/PowerPC,970FX@1 + (unit addresses do not require leading zeroes) + - d-cache-line-size : one cell, L1 data cache line size in bytes + - i-cache-line-size : one cell, L1 instruction cache line size in + bytes + - d-cache-size : one cell, size of L1 data cache in bytes + - i-cache-size : one cell, size of L1 instruction cache in bytes + - linux, boot-cpu : Should be defined if this cpu is the boot cpu. + + Recommended properties: + + - timebase-frequency : a cell indicating the frequency of the + timebase in Hz. This is not directly used by the generic code, + but you are welcome to copy/paste the pSeries code for setting + the kernel timebase/decrementer calibration based on this + value. + - clock-frequency : a cell indicating the CPU core clock frequency + in Hz. A new property will be defined for 64 bit values, but if + your frequency is < 4Ghz, one cell is enough. Here as well as + for the above, the common code doesn't use that property, but + you are welcome to re-use the pSeries or Maple one. A future + kernel version might provide a common function for this. + + You are welcome to add any property you find relevant to your board, + like some information about the mechanism used to soft-reset the + CPUs. For example, Apple puts the GPIO number for CPU soft reset + lines in there as a "soft-reset" property since they start secondary + CPUs by soft-resetting them. + + + d) the /memory node(s) + + To define the physical memory layout of your board, you should + create one or more memory node(s). You can either create a single + node with all memory ranges in its reg property, or you can create + several nodes, as you wish. The unit address (@ part) used for the + full path is the address of the first range of memory defined by a + given node. If you use a single memory node, this will typically be + @0. + + Required properties: + + - device_type : has to be "memory" + - reg : This property contains all the physical memory ranges of + your board. It's a list of addresses/sizes concatenated + together, with the number of cells of each defined by the + #address-cells and #size-cells of the root node. For example, + with both of these properties beeing 2 like in the example given + earlier, a 970 based machine with 6Gb of RAM could typically + have a "reg" property here that looks like: + + 00000000 00000000 00000000 80000000 + 00000001 00000000 00000001 00000000 + + That is a range starting at 0 of 0x80000000 bytes and a range + starting at 0x100000000 and of 0x100000000 bytes. You can see + that there is no memory covering the IO hole between 2Gb and + 4Gb. Some vendors prefer splitting those ranges into smaller + segments, but the kernel doesn't care. + + e) The /chosen node + + This node is a bit "special". Normally, that's where open firmware + puts some variable environment information, like the arguments, or + phandle pointers to nodes like the main interrupt controller, or the + default input/output devices. + + This specification makes a few of these mandatory, but also defines + some linux-specific properties that would be normally constructed by + the prom_init() trampoline when booting with an OF client interface, + but that you have to provide yourself when using the flattened format. + + Required properties: + + - linux,platform : This is your platform number as assigned by the + architecture maintainers + + Recommended properties: + + - bootargs : This zero-terminated string is passed as the kernel + command line + - linux,stdout-path : This is the full path to your standard + console device if any. Typically, if you have serial devices on + your board, you may want to put the full path to the one set as + the default console in the firmware here, for the kernel to pick + it up as it's own default console. If you look at the funciton + set_preferred_console() in arch/ppc64/kernel/setup.c, you'll see + that the kernel tries to find out the default console and has + knowledge of various types like 8250 serial ports. You may want + to extend this function to add your own. + - interrupt-controller : This is one cell containing a phandle + value that matches the "linux,phandle" property of your main + interrupt controller node. May be used for interrupt routing. + + + Note that u-boot creates and fills in the chosen node for platforms + that use it. + + f) the /soc node + + This node is used to represent a system-on-a-chip (SOC) and must be + present if the processor is a SOC. The top-level soc node contains + information that is global to all devices on the SOC. The node name + should contain a unit address for the SOC, which is the base address + of the memory-mapped register set for the SOC. The name of an soc + node should start with "soc", and the remainder of the name should + represent the part number for the soc. For example, the MPC8540's + soc node would be called "soc8540". + + Required properties: + + - device_type : Should be "soc" + - ranges : Should be defined as specified in 1) to describe the + translation of SOC addresses for memory mapped SOC registers. + + Recommended properties: + + - reg : This property defines the address and size of the + memory-mapped registers that are used for the SOC node itself. + It does not include the child device registers - these will be + defined inside each child node. The address specified in the + "reg" property should match the unit address of the SOC node. + - #address-cells : Address representation for "soc" devices. The + format of this field may vary depending on whether or not the + device registers are memory mapped. For memory mapped + registers, this field represents the number of cells needed to + represent the address of the registers. For SOCs that do not + use MMIO, a special address format should be defined that + contains enough cells to represent the required information. + See 1) above for more details on defining #address-cells. + - #size-cells : Size representation for "soc" devices + - #interrupt-cells : Defines the width of cells used to represent + interrupts. Typically this value is <2>, which includes a + 32-bit number that represents the interrupt number, and a + 32-bit number that represents the interrupt sense and level. + This field is only needed if the SOC contains an interrupt + controller. + + The SOC node may contain child nodes for each SOC device that the + platform uses. Nodes should not be created for devices which exist + on the SOC but are not used by a particular platform. See chapter VI + for more information on how to specify devices that are part of an +SOC. + + Example SOC node for the MPC8540: + + soc8540@e0000000 { + #address-cells = <1>; + #size-cells = <1>; + #interrupt-cells = <2>; + device_type = "soc"; + ranges = <00000000 e0000000 00100000> + reg = ; + } + + + +IV - "dtc", the device tree compiler +==================================== + + +dtc source code can be found at + + +WARNING: This version is still in early development stage; the +resulting device-tree "blobs" have not yet been validated with the +kernel. The current generated bloc lacks a useful reserve map (it will +be fixed to generate an empty one, it's up to the bootloader to fill +it up) among others. The error handling needs work, bugs are lurking, +etc... + +dtc basically takes a device-tree in a given format and outputs a +device-tree in another format. The currently supported formats are: + + Input formats: + ------------- + + - "dtb": "blob" format, that is a flattened device-tree block + with + header all in a binary blob. + - "dts": "source" format. This is a text file containing a + "source" for a device-tree. The format is defined later in this + chapter. + - "fs" format. This is a representation equivalent to the + output of /proc/device-tree, that is nodes are directories and + properties are files + + Output formats: + --------------- + + - "dtb": "blob" format + - "dts": "source" format + - "asm": assembly language file. This is a file that can be + sourced by gas to generate a device-tree "blob". That file can + then simply be added to your Makefile. Additionally, the + assembly file exports some symbols that can be use + + +The syntax of the dtc tool is + + dtc [-I ] [-O ] + [-o output-filename] [-V output_version] input_filename + + +The "output_version" defines what versio of the "blob" format will be +generated. Supported versions are 1,2,3 and 16. The default is +currently version 3 but that may change in the future to version 16. + +Additionally, dtc performs various sanity checks on the tree, like the +uniqueness of linux,phandle properties, validity of strings, etc... + +The format of the .dts "source" file is "C" like, supports C and C++ +style commments. + +/ { +} + +The above is the "device-tree" definition. It's the only statement +supported currently at the toplevel. + +/ { + property1 = "string_value"; /* define a property containing a 0 + * terminated string + */ + + property2 = <1234abcd>; /* define a property containing a + * numerical 32 bits value (hexadecimal) + */ + + property3 = <12345678 12345678 deadbeef>; + /* define a property containing 3 + * numerical 32 bits values (cells) in + * hexadecimal + */ + property4 = [0a 0b 0c 0d de ea ad be ef]; + /* define a property whose content is + * an arbitrary array of bytes + */ + + childnode@addresss { /* define a child node named "childnode" + * whose unit name is "childnode at + * address" + */ + + childprop = "hello\n"; /* define a property "childprop" of + * childnode (in this case, a string) + */ + }; +}; + +Nodes can contain other nodes etc... thus defining the hierarchical +structure of the tree. + +Strings support common escape sequences from C: "\n", "\t", "\r", +"\(octal value)", "\x(hex value)". + +It is also suggested that you pipe your source file through cpp (gcc +preprocessor) so you can use #include's, #define for constants, etc... + +Finally, various options are planned but not yet implemented, like +automatic generation of phandles, labels (exported to the asm file so +you can point to a property content and change it easily from whatever +you link the device-tree with), label or path instead of numeric value +in some cells to "point" to a node (replaced by a phandle at compile +time), export of reserve map address to the asm file, ability to +specify reserve map content at compile time, etc... + +We may provide a .h include file with common definitions of that +proves useful for some properties (like building PCI properties or +interrupt maps) though it may be better to add a notion of struct +definitions to the compiler... + + +V - Recommendations for a bootloader +==================================== + + +Here are some various ideas/recommendations that have been proposed +while all this has been defined and implemented. + + - The bootloader may want to be able to use the device-tree itself + and may want to manipulate it (to add/edit some properties, + like physical memory size or kernel arguments). At this point, 2 + choices can be made. Either the bootloader works directly on the + flattened format, or the bootloader has its own internal tree + representation with pointers (similar to the kernel one) and + re-flattens the tree when booting the kernel. The former is a bit + more difficult to edit/modify, the later requires probably a bit + more code to handle the tree structure. Note that the structure + format has been designed so it's relatively easy to "insert" + properties or nodes or delete them by just memmoving things + around. It contains no internal offsets or pointers for this + purpose. + + - An example of code for iterating nodes & retreiving properties + directly from the flattened tree format can be found in the kernel + file arch/ppc64/kernel/prom.c, look at scan_flat_dt() function, + it's usage in early_init_devtree(), and the corresponding various + early_init_dt_scan_*() callbacks. That code can be re-used in a + GPL bootloader, and as the author of that code, I would be happy + do discuss possible free licencing to any vendor who wishes to + integrate all or part of this code into a non-GPL bootloader. + + + +VI - System-on-a-chip devices and nodes +======================================= + +Many companies are now starting to develop system-on-a-chip +processors, where the processor core (cpu) and many peripheral devices +exist on a single piece of silicon. For these SOCs, an SOC node +should be used that defines child nodes for the devices that make +up the SOC. While platforms are not required to use this model in +order to boot the kernel, it is highly encouraged that all SOC +implementations define as complete a flat-device-tree as possible to +describe the devices on the SOC. This will allow for the +genericization of much of the kernel code. + + +1) Defining child nodes of an SOC +--------------------------------- + +Each device that is part of an SOC may have its own node entry inside +the SOC node. For each device that is included in the SOC, the unit +address property represents the address offset for this device's +memory-mapped registers in the parent's address space. The parent's +address space is defined by the "ranges" property in the top-level soc +node. The "reg" property for each node that exists directly under the +SOC node should contain the address mapping from the child address space +to the parent SOC address space and the size of the device's +memory-mapped register file. + +For many devices that may exist inside an SOC, there are predefined +specifications for the format of the device tree node. All SOC child +nodes should follow these specifications, except where noted in this +document. + +See appendix A for an example partial SOC node definition for the +MPC8540. + + +2) Specifying interrupt information for SOC devices +--------------------------------------------------- + +Each device that is part of an SOC and which generates interrupts +should have the following properties: + + - interrupt-parent : contains the phandle of the interrupt + controller which handles interrupts for this device + - interrupts : a list of tuples representing the interrupt + number and the interrupt sense and level for each interupt + for this device. + +This information is used by the kernel to build the interrupt table +for the interrupt controllers in the system. + +Sense and level information should be encoded as follows: + + Devices connected to openPIC-compatible controllers should encode + sense and polarity as follows: + + 0 = high to low edge sensitive type enabled + 1 = active low level sensitive type enabled + 2 = low to high edge sensitive type enabled + 3 = active high level sensitive type enabled + + ISA PIC interrupt controllers should adhere to the ISA PIC + encodings listed below: + + 0 = active low level sensitive type enabled + 1 = active high level sensitive type enabled + 2 = high to low edge sensitive type enabled + 3 = low to high edge sensitive type enabled + + + +3) Representing devices without a current OF specification +---------------------------------------------------------- + +Currently, there are many devices on SOCs that do not have a standard +representation pre-defined as part of the open firmware +specifications, mainly because the boards that contain these SOCs are +not currently booted using open firmware. This section contains +descriptions for the SOC devices for which new nodes have been +defined; this list will expand as more and more SOC-containing +platforms are moved over to use the flattened-device-tree model. + + a) MDIO IO device + + The MDIO is a bus to which the PHY devices are connected. For each + device that exists on this bus, a child node should be created. See + the definition of the PHY node below for an example of how to define + a PHY. + + Required properties: + - reg : Offset and length of the register set for the device + - device_type : Should be "mdio" + - compatible : Should define the compatible device type for the + mdio. Currently, this is most likely to be "gianfar" + + Example: + + mdio@24520 { + reg = <24520 20>; + + ethernet-phy@0 { + ...... + }; + }; + + + b) Gianfar-compatible ethernet nodes + + Required properties: + + - device_type : Should be "network" + - model : Model of the device. Can be "TSEC", "eTSEC", or "FEC" + - compatible : Should be "gianfar" + - reg : Offset and length of the register set for the device + - address : List of bytes representing the ethernet address of + this controller + - interrupts : where a is the interrupt number and b is a + field that represents an encoding of the sense and level + information for the interrupt. This should be encoded based on + the information in section 2) depending on the type of interrupt + controller you have. + - interrupt-parent : the phandle for the interrupt controller that + services interrupts for this device. + - phy-handle : The phandle for the PHY connected to this ethernet + controller. + + Example: + + ethernet@24000 { + #size-cells = <0>; + device_type = "network"; + model = "TSEC"; + compatible = "gianfar"; + reg = <24000 1000>; + address = [ 00 E0 0C 00 73 00 ]; + interrupts = ; + interrupt-parent = <40000>; + phy-handle = <2452000> + }; + + + + c) PHY nodes + + Required properties: + + - device_type : Should be "ethernet-phy" + - interrupts : where a is the interrupt number and b is a + field that represents an encoding of the sense and level + information for the interrupt. This should be encoded based on + the information in section 2) depending on the type of interrupt + controller you have. + - interrupt-parent : the phandle for the interrupt controller that + services interrupts for this device. + - reg : The ID number for the phy, usually a small integer + - linux,phandle : phandle for this node; likely referenced by an + ethernet controller node. + + + Example: + + ethernet-phy@0 { + linux,phandle = <2452000> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <0>; + device_type = "ethernet-phy"; + }; + + + d) Interrupt controllers + + Some SOC devices contain interrupt controllers that are different + from the standard Open PIC specification. The SOC device nodes for + these types of controllers should be specified just like a standard + OpenPIC controller. Sense and level information should be encoded + as specified in section 2) of this chapter for each device that + specifies an interrupt. + + Example : + + pic@40000 { + linux,phandle = <40000>; + clock-frequency = <0>; + interrupt-controller; + #address-cells = <0>; + reg = <40000 40000>; + built-in; + compatible = "chrp,open-pic"; + device_type = "open-pic"; + big-endian; + }; + + + e) I2C + + Required properties : + + - device_type : Should be "i2c" + - reg : Offset and length of the register set for the device + + Recommended properties : + + - compatible : Should be "fsl-i2c" for parts compatible with + Freescale I2C specifications. + - interrupts : where a is the interrupt number and b is a + field that represents an encoding of the sense and level + information for the interrupt. This should be encoded based on + the information in section 2) depending on the type of interrupt + controller you have. + - interrupt-parent : the phandle for the interrupt controller that + services interrupts for this device. + - dfsrr : boolean; if defined, indicates that this I2C device has + a digital filter sampling rate register + - fsl5200-clocking : boolean; if defined, indicated that this device + uses the FSL 5200 clocking mechanism. + + Example : + + i2c@3000 { + interrupt-parent = <40000>; + interrupts = <1b 3>; + reg = <3000 18>; + device_type = "i2c"; + compatible = "fsl-i2c"; + dfsrr; + }; + + + More devices will be defined as this spec matures. + + +Appendix A - Sample SOC node for MPC8540 +======================================== + +Note that the #address-cells and #size-cells for the SoC node +in this example have been explicitly listed; these are likely +not necessary as they are usually the same as the root node. + + soc8540@e0000000 { + #address-cells = <1>; + #size-cells = <1>; + #interrupt-cells = <2>; + device_type = "soc"; + ranges = <00000000 e0000000 00100000> + reg = ; + + mdio@24520 { + reg = <24520 20>; + device_type = "mdio"; + compatible = "gianfar"; + + ethernet-phy@0 { + linux,phandle = <2452000> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <0>; + device_type = "ethernet-phy"; + }; + + ethernet-phy@1 { + linux,phandle = <2452001> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <1>; + device_type = "ethernet-phy"; + }; + + ethernet-phy@3 { + linux,phandle = <2452002> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <3>; + device_type = "ethernet-phy"; + }; + + }; + + ethernet@24000 { + #size-cells = <0>; + device_type = "network"; + model = "TSEC"; + compatible = "gianfar"; + reg = <24000 1000>; + address = [ 00 E0 0C 00 73 00 ]; + interrupts = ; + interrupt-parent = <40000>; + phy-handle = <2452000>; + }; + + ethernet@25000 { + #address-cells = <1>; + #size-cells = <0>; + device_type = "network"; + model = "TSEC"; + compatible = "gianfar"; + reg = <25000 1000>; + address = [ 00 E0 0C 00 73 01 ]; + interrupts = <13 3 14 3 18 3>; + interrupt-parent = <40000>; + phy-handle = <2452001>; + }; + + ethernet@26000 { + #address-cells = <1>; + #size-cells = <0>; + device_type = "network"; + model = "FEC"; + compatible = "gianfar"; + reg = <26000 1000>; + address = [ 00 E0 0C 00 73 02 ]; + interrupts = <19 3>; + interrupt-parent = <40000>; + phy-handle = <2452002>; + }; + + serial@4500 { + device_type = "serial"; + compatible = "ns16550"; + reg = <4500 100>; + clock-frequency = <0>; + interrupts = <1a 3>; + interrupt-parent = <40000>; + }; + + pic@40000 { + linux,phandle = <40000>; + clock-frequency = <0>; + interrupt-controller; + #address-cells = <0>; + reg = <40000 40000>; + built-in; + compatible = "chrp,open-pic"; + device_type = "open-pic"; + big-endian; + }; + + i2c@3000 { + interrupt-parent = <40000>; + interrupts = <1b 3>; + reg = <3000 18>; + device_type = "i2c"; + compatible = "fsl-i2c"; + dfsrr; + }; + + }; diff --git a/trunk/Documentation/scsi/ChangeLog.megaraid_sas b/trunk/Documentation/scsi/ChangeLog.megaraid_sas new file mode 100644 index 000000000000..f8c16cbf56ba --- /dev/null +++ b/trunk/Documentation/scsi/ChangeLog.megaraid_sas @@ -0,0 +1,24 @@ +1 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro +2 Current Version : 00.00.02.02 +3 Older Version : 00.00.02.01 + +i.

This is because most SOCs have several +SPI-capable controllers, and only the ones actually usable on a given +board should normally be set up and registered. + +So for example arch/.../mach-*/board-*.c files might have code like: + + #include /* for mysoc_spi_data */ + + /* if your mach-* infrastructure doesn't support kernels that can + * run on multiple boards, pdata wouldn't benefit from "__init". + */ + static struct mysoc_spi_data __init pdata = { ... }; + + static __init board_init(void) + { + ... + /* this board only uses SPI controller #2 */ + mysoc_register_spi(2, &pdata); + ... + } + +And SOC-specific utility code might look something like: + + #include + + static struct platform_device spi2 = { ... }; + + void mysoc_register_spi(unsigned n, struct mysoc_spi_data *pdata) + { + struct mysoc_spi_data *pdata2; + + pdata2 = kmalloc(sizeof *pdata2, GFP_KERNEL); + *pdata2 = pdata; + ... + if (n == 2) { + spi2->dev.platform_data = pdata2; + register_platform_device(&spi2); + + /* also: set up pin modes so the spi2 signals are + * visible on the relevant pins ... bootloaders on + * production boards may already have done this, but + * developer boards will often need Linux to do it. + */ + } + ... + } + +Notice how the platform_data for boards may be different, even if the +same SOC controller is used. For example, on one board SPI might use +an external clock, where another derives the SPI clock from current +settings of some master clock. + + +DECLARE SLAVE DEVICES + +The second kind of information is a list of what SPI slave devices exist +on the target board, often with some board-specific data needed for the +driver to work correctly. + +Normally your arch/.../mach-*/board-*.c files would provide a small table +listing the SPI devices on each board. (This would typically be only a +small handful.) That might look like: + + static struct ads7846_platform_data ads_info = { + .vref_delay_usecs = 100, + .x_plate_ohms = 580, + .y_plate_ohms = 410, + }; + + static struct spi_board_info spi_board_info[] __initdata = { + { + .modalias = "ads7846", + .platform_data = &ads_info, + .mode = SPI_MODE_0, + .irq = GPIO_IRQ(31), + .max_speed_hz = 120000 /* max sample rate at 3V */ * 16, + .bus_num = 1, + .chip_select = 0, + }, + }; + +Again, notice how board-specific information is provided; each chip may need +several types. This example shows generic constraints like the fastest SPI +clock to allow (a function of board voltage in this case) or how an IRQ pin +is wired, plus chip-specific constraints like an important delay that's +changed by the capacitance at one pin. + +(There's also "controller_data", information that may be useful to the +controller driver. An example would be peripheral-specific DMA tuning +data or chipselect callbacks. This is stored in spi_device later.) + +The board_info should provide enough information to let the system work +without the chip's driver being loaded. The most troublesome aspect of +that is likely the SPI_CS_HIGH bit in the spi_device.mode field, since +sharing a bus with a device that interprets chipselect "backwards" is +not possible. + +Then your board initialization code would register that table with the SPI +infrastructure, so that it's available later when the SPI master controller +driver is registered: + + spi_register_board_info(spi_board_info, ARRAY_SIZE(spi_board_info)); + +Like with other static board-specific setup, you won't unregister those. + +The widely used "card" style computers bundle memory, cpu, and little else +onto a card that's maybe just thirty square centimeters. On such systems, +your arch/.../mach-.../board-*.c file would primarily provide information +about the devices on the mainboard into which such a card is plugged. That +certainly includes SPI devices hooked up through the card connectors! + + +NON-STATIC CONFIGURATIONS + +Developer boards often play by different rules than product boards, and one +example is the potential need to hotplug SPI devices and/or controllers. + +For those cases you might need to use use spi_busnum_to_master() to look +up the spi bus master, and will likely need spi_new_device() to provide the +board info based on the board that was hotplugged. Of course, you'd later +call at least spi_unregister_device() when that board is removed. + +When Linux includes support for MMC/SD/SDIO/DataFlash cards through SPI, those +configurations will also be dynamic. Fortunately, those devices all support +basic device identification probes, so that support should hotplug normally. + + +How do I write an "SPI Protocol Driver"? +---------------------------------------- +All SPI drivers are currently kernel drivers. A userspace driver API +would just be another kernel driver, probably offering some lowlevel +access through aio_read(), aio_write(), and ioctl() calls and using the +standard userspace sysfs mechanisms to bind to a given SPI device. + +SPI protocol drivers somewhat resemble platform device drivers: + + static struct spi_driver CHIP_driver = { + .driver = { + .name = "CHIP", + .bus = &spi_bus_type, + .owner = THIS_MODULE, + }, + + .probe = CHIP_probe, + .remove = __devexit_p(CHIP_remove), + .suspend = CHIP_suspend, + .resume = CHIP_resume, + }; + +The driver core will autmatically attempt to bind this driver to any SPI +device whose board_info gave a modalias of "CHIP". Your probe() code +might look like this unless you're creating a class_device: + + static int __devinit CHIP_probe(struct spi_device *spi) + { + struct CHIP *chip; + struct CHIP_platform_data *pdata; + + /* assuming the driver requires board-specific data: */ + pdata = &spi->dev.platform_data; + if (!pdata) + return -ENODEV; + + /* get memory for driver's per-chip state */ + chip = kzalloc(sizeof *chip, GFP_KERNEL); + if (!chip) + return -ENOMEM; + dev_set_drvdata(&spi->dev, chip); + + ... etc + return 0; + } + +As soon as it enters probe(), the driver may issue I/O requests to +the SPI device using "struct spi_message". When remove() returns, +the driver guarantees that it won't submit any more such messages. + + - An spi_message is a sequence of of protocol operations, executed + as one atomic sequence. SPI driver controls include: + + + when bidirectional reads and writes start ... by how its + sequence of spi_transfer requests is arranged; + + + optionally defining short delays after transfers ... using + the spi_transfer.delay_usecs setting; + + + whether the chipselect becomes inactive after a transfer and + any delay ... by using the spi_transfer.cs_change flag; + + + hinting whether the next message is likely to go to this same + device ... using the spi_transfer.cs_change flag on the last + transfer in that atomic group, and potentially saving costs + for chip deselect and select operations. + + - Follow standard kernel rules, and provide DMA-safe buffers in + your messages. That way controller drivers using DMA aren't forced + to make extra copies unless the hardware requires it (e.g. working + around hardware errata that force the use of bounce buffering). + + If standard dma_map_single() handling of these buffers is inappropriate, + you can use spi_message.is_dma_mapped to tell the controller driver + that you've already provided the relevant DMA addresses. + + - The basic I/O primitive is spi_async(). Async requests may be + issued in any context (irq handler, task, etc) and completion + is reported using a callback provided with the message. + After any detected error, the chip is deselected and processing + of that spi_message is aborted. + + - There are also synchronous wrappers like spi_sync(), and wrappers + like spi_read(), spi_write(), and spi_write_then_read(). These + may be issued only in contexts that may sleep, and they're all + clean (and small, and "optional") layers over spi_async(). + + - The spi_write_then_read() call, and convenience wrappers around + it, should only be used with small amounts of data where the + cost of an extra copy may be ignored. It's designed to support + common RPC-style requests, such as writing an eight bit command + and reading a sixteen bit response -- spi_w8r16() being one its + wrappers, doing exactly that. + +Some drivers may need to modify spi_device characteristics like the +transfer mode, wordsize, or clock rate. This is done with spi_setup(), +which would normally be called from probe() before the first I/O is +done to the device. + +While "spi_device" would be the bottom boundary of the driver, the +upper boundaries might include sysfs (especially for sensor readings), +the input layer, ALSA, networking, MTD, the character device framework, +or other Linux subsystems. + +Note that there are two types of memory your driver must manage as part +of interacting with SPI devices. + + - I/O buffers use the usual Linux rules, and must be DMA-safe. + You'd normally allocate them from the heap or free page pool. + Don't use the stack, or anything that's declared "static". + + - The spi_message and spi_transfer metadata used to glue those + I/O buffers into a group of protocol transactions. These can + be allocated anywhere it's convenient, including as part of + other allocate-once driver data structures. Zero-init these. + +If you like, spi_message_alloc() and spi_message_free() convenience +routines are available to allocate and zero-initialize an spi_message +with several transfers. + + +How do I write an "SPI Master Controller Driver"? +------------------------------------------------- +An SPI controller will probably be registered on the platform_bus; write +a driver to bind to the device, whichever bus is involved. + +The main task of this type of driver is to provide an "spi_master". +Use spi_alloc_master() to allocate the master, and class_get_devdata() +to get the driver-private data allocated for that device. + + struct spi_master *master; + struct CONTROLLER *c; + + master = spi_alloc_master(dev, sizeof *c); + if (!master) + return -ENODEV; + + c = class_get_devdata(&master->cdev); + +The driver will initialize the fields of that spi_master, including the +bus number (maybe the same as the platform device ID) and three methods +used to interact with the SPI core and SPI protocol drivers. It will +also initialize its own internal state. + + master->setup(struct spi_device *spi) + This sets up the device clock rate, SPI mode, and word sizes. + Drivers may change the defaults provided by board_info, and then + call spi_setup(spi) to invoke this routine. It may sleep. + + master->transfer(struct spi_device *spi, struct spi_message *message) + This must not sleep. Its responsibility is arrange that the + transfer happens and its complete() callback is issued; the two + will normally happen later, after other transfers complete. + + master->cleanup(struct spi_device *spi) + Your controller driver may use spi_device.controller_state to hold + state it dynamically associates with that device. If you do that, + be sure to provide the cleanup() method to free that state. + +The bulk of the driver will be managing the I/O queue fed by transfer(). + +That queue could be purely conceptual. For example, a driver used only +for low-frequency sensor acess might be fine using synchronous PIO. + +But the queue will probably be very real, using message->queue, PIO, +often DMA (especially if the root filesystem is in SPI flash), and +execution contexts like IRQ handlers, tasklets, or workqueues (such +as keventd). Your driver can be as fancy, or as simple, as you need. + + +THANKS TO +--------- +Contributors to Linux-SPI discussions include (in alphabetical order, +by last name): + +David Brownell +Russell King +Dmitry Pervushin +Stephen Street +Mark Underwood +Andrew Victor +Vitaly Wool + diff --git a/trunk/Documentation/sysctl/vm.txt b/trunk/Documentation/sysctl/vm.txt index 6910c0136f8d..a46c10fcddfc 100644 --- a/trunk/Documentation/sysctl/vm.txt +++ b/trunk/Documentation/sysctl/vm.txt @@ -27,6 +27,8 @@ Currently, these files are in /proc/sys/vm: - laptop_mode - block_dump - drop-caches +- zone_reclaim_mode +- zone_reclaim_interval ============================================================== @@ -120,3 +122,59 @@ set to pcp->high/4.

Module dependencies +====================== +For it to work properly, the driver needs kernel support for Video4Linux and +USB. + +The following options of the kernel configuration file must be enabled and +corresponding modules must be compiled: + + # Multimedia devices + # + CONFIG_VIDEO_DEV=m + +To enable advanced debugging functionality on the device through /sysfs: + + # Multimedia devices + # + CONFIG_VIDEO_ADV_DEBUG=y + + # USB support + # + CONFIG_USB=m + +In addition, depending on the hardware being used, the modules below are +necessary: + + # USB Host Controller Drivers + # + CONFIG_USB_EHCI_HCD=m + CONFIG_USB_UHCI_HCD=m + CONFIG_USB_OHCI_HCD=m + +And finally: + + # USB Multimedia devices + # + CONFIG_USB_ET61X251=m + + +6. Module loading +================= +To use the driver, it is necessary to load the "et61x251" module into memory +after every other module required: "videodev", "usbcore" and, depending on +the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". + +Loading can be done as shown below: + + [root@localhost home]# modprobe et61x251 + +At this point the devices should be recognized.

Optional device control through "sysfs" +========================================== +If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, +it is possible to read and write both the ET61X[12]51 and the image sensor +registers by using the "sysfs" filesystem interface. + +There are four files in the /sys/class/video4linux/videoX directory for each +registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files +control the ET61X[12]51 bridge, while the other two control the sensor chip. +"reg" and "i2c_reg" hold the values of the current register index where the +following reading/writing operations are addressed at through "val" and +"i2c_val". Their use is not intended for end-users, unless you know what you +are doing.

Notes for V4L2 application developers +======================================== +This driver follows the V4L2 API specifications. In particular, it enforces two +rules: + +- exactly one I/O method, either "mmap" or "read", is associated with each +file descriptor. Once it is selected, the application must close and reopen the +device to switch to the other I/O method; + +- although it is not mandatory, previously mapped buffer memory should always +be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. +The same number of buffers as before will be allocated again to match the size +of the new video frames, so you have to map the buffers again before any I/O +attempts on them. + +Consistently with the hardware limits, this driver also supports image +downscaling with arbitrary scaling factors from 1 and 2 in both directions. +However, the V4L2 API specifications don't correctly define how the scaling +factor can be chosen arbitrarily by the "negotiation" of the "source" and +"target" rectangles. To work around this flaw, we have added the convention +that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the +scaling factor is restored to 1. + +This driver supports two different video formats: the first one is the "8-bit +Sequential Bayer" format and can be used to obtain uncompressed video data +from the device through the current I/O method, while the second one provides +"raw" compressed video data (without frame headers not related to the +compressed data). The current compression quality may vary from 0 to 1 and can +be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP +V4L2 ioctl's. + + +11.
