UBI stands for "Unsorted +Block Images". UBIFS is a flash file system, which means it is designed +to work with flash devices. It is important to understand, that UBIFS +is completely different to any traditional file-system in Linux, like +Ext2, XFS, JFS, etc. UBIFS represents a separate class of file-systems +which work with MTD devices, not block devices. The other Linux +file-system of this class is JFFS2. + +To make it more clear, here is a small comparison of MTD devices and +block devices. + +1 MTD devices represent flash devices and they consist of eraseblocks of + rather large size, typically about 128KiB. Block devices consist of + small blocks, typically 512 bytes. +2 MTD devices support 3 main operations - read from some offset within an + eraseblock, write to some offset within an eraseblock, and erase a whole + eraseblock. Block devices support 2 main operations - read a whole + block and write a whole block. +3 The whole eraseblock has to be erased before it becomes possible to + re-write its contents. Blocks may be just re-written. +4 Eraseblocks become worn out after some number of erase cycles - + typically 100K-1G for SLC NAND and NOR flashes, and 1K-10K for MLC + NAND flashes. Blocks do not have the wear-out property. +5 Eraseblocks may become bad (only on NAND flashes) and software should + deal with this. Blocks on hard drives typically do not become bad, + because hardware has mechanisms to substitute bad blocks, at least in + modern LBA disks. + +It should be quite obvious why UBIFS is very different to traditional +file-systems. + +UBIFS works on top of UBI. UBI is a separate software layer which may be +found in drivers/mtd/ubi. UBI is basically a volume management and +wear-leveling layer. It provides so called UBI volumes which is a higher +level abstraction than a MTD device. The programming model of UBI devices +is very similar to MTD devices - they still consist of large eraseblocks, +they have read/write/erase operations, but UBI devices are devoid of +limitations like wear and bad blocks (items 4 and 5 in the above list). + +In a sense, UBIFS is a next generation of JFFS2 file-system, but it is +very different and incompatible to JFFS2. The following are the main +differences. + +* JFFS2 works on top of MTD devices, UBIFS depends on UBI and works on + top of UBI volumes. +* JFFS2 does not have on-media index and has to build it while mounting, + which requires full media scan. UBIFS maintains the FS indexing + information on the flash media and does not require full media scan, + so it mounts many times faster than JFFS2. +* JFFS2 is a write-through file-system, while UBIFS supports write-back, + which makes UBIFS much faster on writes. + +Similarly to JFFS2, UBIFS supports on-the-flight compression which makes +it possible to fit quite a lot of data to the flash. + +Similarly to JFFS2, UBIFS is tolerant of unclean reboots and power-cuts. +It does not need stuff like ckfs.ext2. UBIFS automatically replays its +journal and recovers from crashes, ensuring that the on-flash data +structures are consistent. + +UBIFS scales logarithmically (most of the data structures it uses are +trees), so the mount time and memory consumption do not linearly depend +on the flash size, like in case of JFFS2. This is because UBIFS +maintains the FS index on the flash media. However, UBIFS depends on +UBI, which scales linearly. So overall UBI/UBIFS stack scales linearly. +Nevertheless, UBI/UBIFS scales considerably better than JFFS2. + +The authors of UBIFS believe, that it is possible to develop UBI2 which +would scale logarithmically as well. UBI2 would support the same API as UBI, +but it would be binary incompatible to UBI.

There is no +standard PowerPC firmware interface, so the boot wrapper is designed to +be adaptable for each kind of image that needs to be built. + +The boot wrapper can be found in the arch/powerpc/boot/ directory. The +Makefile in that directory has targets for all the available image types. +The different image types are used to support all of the various firmware +interfaces found on PowerPC platforms. OpenFirmware is the most commonly +used firmware type on general purpose PowerPC systems from Apple, IBM and +others. U-Boot is typically found on embedded PowerPC hardware, but there +are a handful of other firmware implementations which are also popular. Each +firmware interface requires a different image format. + +The boot wrapper is built from the makefile in arch/powerpc/boot/Makefile and +it uses the wrapper script (arch/powerpc/boot/wrapper) to generate target +image. The details of the build system is discussed in the next section. +Currently, the following image format targets exist: + + cuImage.%: Backwards compatible uImage for older version of + U-Boot (for versions that don't understand the device + tree). This image embeds a device tree blob inside + the image. The boot wrapper, kernel and device tree + are all embedded inside the U-Boot uImage file format + with boot wrapper code that extracts data from the old + bd_info structure and loads the data into the device + tree before jumping into the kernel. + Because of the series of #ifdefs found in the + bd_info structure used in the old U-Boot interfaces, + cuImages are platform specific. Each specific + U-Boot platform has a different platform init file + which populates the embedded device tree with data + from the platform specific bd_info file. The platform + specific cuImage platform init code can be found in + arch/powerpc/boot/cuboot.*.c. Selection of the correct + cuImage init code for a specific board can be found in + the wrapper structure. + dtbImage.%: Similar to zImage, except device tree blob is embedded + inside the image instead of provided by firmware. The + output image file can be either an elf file or a flat + binary depending on the platform. + dtbImages are used on systems which do not have an + interface for passing a device tree directly. + dtbImages are similar to simpleImages except that + dtbImages have platform specific code for extracting + data from the board firmware, but simpleImages do not + talk to the firmware at all. + PlayStation 3 support uses dtbImage. So do Embedded + Planet boards using the PlanetCore firmware. Board + specific initialization code is typically found in a + file named arch/powerpc/boot/.c; but this + can be overridden by the wrapper script. + simpleImage.%: Firmware independent compressed image that does not + depend on any particular firmware interface and embeds + a device tree blob. This image is a flat binary that + can be loaded to any location in RAM and jumped to. + Firmware cannot pass any configuration data to the + kernel with this image type and it depends entirely on + the embedded device tree for all information. + The simpleImage is useful for booting systems with + an unknown firmware interface or for booting from + a debugger when no firmware is present (such as on + the Xilinx Virtex platform). The only assumption that + simpleImage makes is that RAM is correctly initialized + and that the MMU is either off or has RAM mapped to + base address 0. + simpleImage also supports inserting special platform + specific initialization code to the start of the bootup + sequence. The virtex405 platform uses this feature to + ensure that the cache is invalidated before caching + is enabled. Platform specific initialization code is + added as part of the wrapper script and is keyed on + the image target name. For example, all + simpleImage.virtex405-* targets will add the + virtex405-head.S initialization code (This also means + that the dts file for virtex405 targets should be + named (virtex405-.dts). Search the wrapper + script for 'virtex405' and see the file + arch/powerpc/boot/virtex405-head.S for details. + treeImage.%; Image format for used with OpenBIOS firmware found + on some ppc4xx hardware. This image embeds a device + tree blob inside the image. + uImage: Native image format used by U-Boot. The uImage target + does not add any boot code. It just wraps a compressed + vmlinux in the uImage data structure. This image + requires a version of U-Boot that is able to pass + a device tree to the kernel at boot. If using an older + version of U-Boot, then you need to use a cuImage + instead. + zImage.%: Image format which does not embed a device tree. + Used by OpenFirmware and other firmware interfaces + which are able to supply a device tree. This image + expects firmware to provide the device tree at boot. + Typically, if you have general purpose PowerPC + hardware then you want this image format. + +Image types which embed a device tree blob (simpleImage, dtbImage, treeImage, +and cuImage) all generate the device tree blob from a file in the +arch/powerpc/boot/dts/ directory. The Makefile selects the correct device +tree source based on the name of the target. Therefore, if the kernel is +built with 'make treeImage.walnut simpleImage.virtex405-ml403', then the +build system will use arch/powerpc/boot/dts/walnut.dts to build +treeImage.walnut and arch/powerpc/boot/dts/virtex405-ml403.dts to build +the simpleImage.virtex405-ml403. + +Two special targets called 'zImage' and 'zImage.initrd' also exist. These +targets build all the default images as selected by the kernel configuration. +Default images are selected by the boot wrapper Makefile +(arch/powerpc/boot/Makefile) by adding targets to the $image-y variable. Look +at the Makefile to see which default image targets are available. + +How it is built +--------------- +arch/powerpc is designed to support multiplatform kernels, which means +that a single vmlinux image can be booted on many different target boards. +It also means that the boot wrapper must be able to wrap for many kinds of +images on a single build. The design decision was made to not use any +conditional compilation code (#ifdef, etc) in the boot wrapper source code. +All of the boot wrapper pieces are buildable at any time regardless of the +kernel configuration. Building all the wrapper bits on every kernel build +also ensures that obscure parts of the wrapper are at the very least compile +tested in a large variety of environments. + +The wrapper is adapted for different image types at link time by linking in +just the wrapper bits that are appropriate for the image type. The 'wrapper +script' (found in arch/powerpc/boot/wrapper) is called by the Makefile and +is responsible for selecting the correct wrapper bits for the image type. +The arguments are well documented in the script's comment block, so they +are not repeated here. However, it is worth mentioning that the script +uses the -p (platform) argument as the main method of deciding which wrapper +bits to compile in. Look for the large 'case "$platform" in' block in the +middle of the script. This is also the place where platform specific fixups +can be selected by changing the link order. + +In particular, care should be taken when working with cuImages. cuImage +wrapper bits are very board specific and care should be taken to make sure +the target you are trying to build is supported by the wrapper bits. diff --git a/Documentation/powerpc/dts-bindings/fsl/board.txt b/Documentation/powerpc/dts-bindings/fsl/board.txt new file mode 100644 index 00000000000..74ae6f1cd2d --- /dev/null +++ b/Documentation/powerpc/dts-bindings/fsl/board.txt @@ -0,0 +1,29 @@ +* Board Control and Status (BCSR) + +Required properties: + + - device_type : Should be "board-control" + - reg : Offset and length of the register set for the device + +Example: + + bcsr@f8000000 { + device_type = "board-control"; + reg = ; + }; + +* Freescale on board FPGA + +This is the memory-mapped registers for on board FPGA. + +Required properities: +- compatible : should be "fsl,fpga-pixis". +- reg : should contain the address and the lenght of the FPPGA register + set. + +Example (MPC8610HPCD): + + board-control@e8000000 { + compatible = "fsl,fpga-pixis"; + reg = <0xe8000000 32>; + }; diff --git a/Documentation/powerpc/dts-bindings/fsl/cpm_qe/cpm.txt b/Documentation/powerpc/dts-bindings/fsl/cpm_qe/cpm.txt new file mode 100644 index 00000000000..088fc471e03 --- /dev/null +++ b/Documentation/powerpc/dts-bindings/fsl/cpm_qe/cpm.txt @@ -0,0 +1,67 @@ +* Freescale Communications Processor Module + +NOTE: This is an interim binding, and will likely change slightly, +as more devices are supported.

PG_private is set if the + * page is dirty and is used for budgeting purposes - dirty pages should not be + * budgeted. The PG_checked flag is set if full budgeting is required for the + * page e.g., when it corresponds to a file hole or it is just beyond the file + * size. The budgeting is done in 'ubifs_write_begin()', because it is OK to + * fail in this function, and the budget is released in 'ubifs_write_end()'. So + * the PG_private and PG_checked flags carry the information about how the page + * was budgeted, to make it possible to release the budget properly. + * + * A thing to keep in mind: inode's 'i_mutex' is locked in most VFS operations + * we implement. However, this is not true for '->writepage()', which might be + * called with 'i_mutex' unlocked. For example, when pdflush is performing + * write-back, it calls 'writepage()' with unlocked 'i_mutex', although the + * inode has 'I_LOCK' flag in this case. At "normal" work-paths 'i_mutex' is + * locked in '->writepage', e.g. in "sys_write -> alloc_pages -> direct reclaim + * path'. So, in '->writepage()' we are only guaranteed that the page is + * locked. + * + * Similarly, 'i_mutex' does not have to be locked in readpage(), e.g., + * readahead path does not have it locked ("sys_read -> generic_file_aio_read + * -> ondemand_readahead -> readpage").

It is nice to have nodes belonging to the same inode + * in one LEB, so we may write data owned by different inodes to different + * journal heads, although at present only one data head is used. + * + * For recovery reasons, the base head contains all inode nodes, all directory + * entry nodes and all truncate nodes. This means that the other heads contain + * only data nodes. + * + * Bud LEBs may be half-indexed. For example, if the bud was not full at the + * time of commit, the bud is retained to continue to be used in the journal, + * even though the "front" of the LEB is now indexed. In that case, the log + * reference contains the offset where the bud starts for the purposes of the + * journal. + * + * The journal size has to be limited, because the larger is the journal, the + * longer it takes to mount UBIFS (scanning the journal) and the more memory it + * takes (indexing in the TNC). + * + * All the journal write operations like 'ubifs_jnl_update()' here, which write + * multiple UBIFS nodes to the journal at one go, are atomic with respect to + * unclean reboots.

It cannot just mark it dirty because there is no guarantee there will + * be enough flash space to write the inode back later. This means UBIFS has + * to have full control over inode "clean <-> dirty" transitions (and pages + * actually). But unfortunately, VFS marks inodes dirty in many places, and it + * does not ask the file-system if it is allowed to do so (there is a notifier, + * but it is not enough), i.e., there is no mechanism to synchronize with this. + * So UBIFS has its own inode dirty flag and its own mutex to serialize + * "clean <-> dirty" transitions. + * + * The @synced_i_size field is used to make sure we never write pages which are + * beyond last synchronized inode size. See 'ubifs_writepage()' for more + * information. + * + * The @ui_size is a "shadow" variable for @inode->i_size and UBIFS uses + * @ui_size instead of @inode->i_size. The reason for this is that UBIFS cannot + * make sure @inode->i_size is always changed under @ui_mutex, because it + * cannot call 'vmtruncate()' with @ui_mutex locked, because it would deadlock + * with 'ubifs_writepage()' (see file.c).

Names of + * extended attributes are described by extended attribute entries (xentries), + * which are almost identical to directory entries, but have different key type. + * + * In other words, the situation with extended attributes is very similar to + * directories. Indeed, any inode (but of course not xattr inodes) may have a + * number of associated xentries, just like directory inodes have associated + * directory entries. Extended attribute entries store the name of the extended + * attribute, the host inode number, and the extended attribute inode number. + * Similarly, direntries store the name, the parent and the target inode + * numbers. Thus, most of the common UBIFS mechanisms may be re-used for + * extended attributes. + * + * The number of extended attributes is not limited, but there is Linux + * limitation on the maximum possible size of the list of all extended + * attributes associated with an inode (%XATTR_LIST_MAX), so UBIFS makes sure + * the sum of all extended attribute names of the inode does not exceed that + * limit. + * + * Extended attributes are synchronous, which means they are written to the + * flash media synchronously and there is no write-back for extended attribute + * inodes. The extended attribute values are not stored in compressed form on + * the media. + * + * Since extended attributes are represented by regular inodes, they are cached + * in the VFS inode cache. The xentries are cached in the LNC cache (see + * tnc.c). + * + * ACL support is not implemented. + */ + +#include +#include +#include "ubifs.h" + +/* + * Limit the number of extended attributes per inode so that the total size + * (xattr_size) is guaranteeded to fit in an 'unsigned int'. + */ +#define MAX_XATTRS_PER_INODE 65535 + +/* + * Extended attribute type constants. + * + * USER_XATTR: user extended attribute ("user.*") + * TRUSTED_XATTR: trusted extended attribute ("trusted.*) + * SECURITY_XATTR: security extended attribute ("security.*") + */ +enum { + USER_XATTR, + TRUSTED_XATTR, + SECURITY_XATTR, +}; + +static struct inode_operations none_inode_operations; +static struct address_space_operations none_address_operations; +static struct file_operations none_file_operations; + +/** + * create_xattr - create an extended attribute. + * @c: UBIFS file-system description object + * @host: host inode + * @nm: extended attribute name + * @value: extended attribute value + * @size: size of extended attribute value + * + * This is a helper function which creates an extended attribute of name @nm + * and value @value for inode @host.

However, drivers may NOT assume + * anything about the availability of the user space at that time and it + * is not correct to request firmware from within @prepare() (it's too + * late to do that). [To work around this limitation, drivers may + * register suspend and hibernation notifiers that are executed before the + * freezing of tasks.] + * + * @complete: Undo the changes made by @prepare(). This method is executed for + * all kinds of resume transitions, following one of the resume callbacks: + * @resume(), @thaw(), @restore(). Also called if the state transition + * fails before the driver's suspend callback (@suspend(), @freeze(), + * @poweroff()) can be executed (e.g. if the suspend callback fails for one + * of the other devices that the PM core has unsuccessfully attempted to + * suspend earlier). + * The PM core executes @complete() after it has executed the appropriate + * resume callback for all devices. + * + * @suspend: Executed before putting the system into a sleep state in which the + * contents of main memory are preserved. Quiesce the device, put it into + * a low power state appropriate for the upcoming system state (such as + * PCI_D3hot), and enable wakeup events as appropriate. + * + * @resume: Executed after waking the system up from a sleep state in which the + * contents of main memory were preserved. Put the device into the + * appropriate state, according to the information saved in memory by the + * preceding @suspend(). The driver starts working again, responding to + * hardware events and software requests. The hardware may have gone + * through a power-off reset, or it may have maintained state from the + * previous suspend() which the driver may rely on while resuming. On most + * platforms, there are no restrictions on availability of resources like + * clocks during @resume(). + * + * @freeze: Hibernation-specific, executed before creating a hibernation image. + * Quiesce operations so that a consistent image can be created, but do NOT + * otherwise put the device into a low power device state and do NOT emit + * system wakeup events. Save in main memory the device settings to be + * used by @restore() during the subsequent resume from hibernation or by + * the subsequent @thaw(), if the creation of the image or the restoration + * of main memory contents from it fails. + * + * @thaw: Hibernation-specific, executed after creating a hibernation image OR + * if the creation of the image fails. Also executed after a failing + * attempt to restore the contents of main memory from such an image. + * Undo the changes made by the preceding @freeze(), so the device can be + * operated in the same way as immediately before the call to @freeze(). + * + * @poweroff: Hibernation-specific, executed after saving a hibernation image. + * Quiesce the device, put it into a low power state appropriate for the + * upcoming system state (such as PCI_D3hot), and enable wakeup events as + * appropriate. + * + * @restore: Hibernation-specific, executed after restoring the contents of main + * memory from a hibernation image. Driver starts working again, + * responding to hardware events and software requests. Drivers may NOT + * make ANY assumptions about the hardware state right prior to @restore(). + * On most platforms, there are no restrictions on availability of + * resources like clocks during @restore(). + * + * All of the above callbacks, except for @complete(), return error codes. + * However, the error codes returned by the resume operations, @resume(), + * @thaw(), and @restore(), do not cause the PM core to abort the resume + * transition during which they are returned.

Still, it is recommended that drivers only return error codes + * from their resume methods in case of an unrecoverable failure (i.e. when the + * device being handled refuses to resume and becomes unusable) to allow us to + * modify the PM core in the future, so that it can avoid attempting to handle + * devices that failed to resume and their children. + * + * It is allowed to unregister devices while the above callbacks are being + * executed.
