YAFFS2 supports 512b page in 'YAFFS1 +compatibility' mode (CONFIG_YAFFS_YAFFS1) and 2K or larger page NAND +in YAFFS2 mode (CONFIG_YAFFS_YAFFS2). + + +A note on licencing +------------------- +YAFFS is available under the GPL and via alternative licensing +arrangements with Aleph One. If you're using YAFFS as a Linux kernel +file system then it will be under the GPL. For use in other situations +you should discuss licensing issues with Aleph One. + + +Terminology +----------- +Page - NAND addressable unit (normally 512b or 2Kbyte size) - can + be read, written, marked bad. Has associated OOB. +Block - Eraseable unit. 64 Pages. (128K on 2K NAND, 32K on 512b NAND) +OOB - 'spare area' of each page for ECC, bad block marked and YAFFS + tags. 16 bytes per 512b - 64 bytes for 2K page size. +Chunk - Basic YAFFS addressable unit. Same size as Page. +Object - YAFFS Object: File, Directory, Link, Device etc. + +YAFFS design +------------ + +YAFFS is a log-structured filesystem. It is designed particularly for +NAND (as opposed to NOR) flash, to be flash-friendly, robust due to +journalling, and to have low RAM and boot time overheads. File data is +stored in 'chunks'. Chunks are the same size as NAND pages. Each page +is marked with file id and chunk number. These marking 'tags' are +stored in the OOB (or 'spare') region of the flash. The chunk number +is determined by dividing the file position by the chunk size. Each +chunk has a number of valid bytes, which equals the page size for all +except the last chunk in a file. + +File 'headers' are stored as the first page in a file, marked as a +different type to data pages. The same mechanism is used to store +directories, device files, links etc. The first page describes which +type of object it is. + +YAFFS2 never re-writes a page, because the spec of NAND chips does not +allow it. (YAFFS1 used to mark a block 'deleted' in the OOB). Deletion +is managed by moving deleted objects to the special, hidden 'unlinked' +directory. These records are preserved until all the pages containing +the object have been erased (We know when this happen by keeping a +count of chunks remaining on the system for each object - when it +reaches zero the object really is gone). + +When data in a file is overwritten, the relevant chunks are replaced +by writing new pages to flash containing the new data but the same +tags. + +Pages are also marked with a short (2 bit) serial number that +increments each time the page at this position is incremented. The +reason for this is that if power loss/crash/other act of demonic +forces happens before the replaced page is marked as discarded, it is +possible to have two pages with the same tags. The serial number is +used to arbitrate. + +A block containing only discarded pages (termed a dirty block) is an +obvious candidate for garbage collection. Otherwise valid pages can be +copied off a block thus rendering the whole block discarded and ready +for garbage collection. + +In theory you don't need to hold the file structure in RAM... you +could just scan the whole flash looking for pages when you need them. +In practice though you'd want better file access times than that! The +mechanism proposed here is to have a list of __u16 page addresses +associated with each file. Since there are 2^18 pages in a 128MB NAND, +a __u16 is insufficient to uniquely identify a page but is does +identify a group of 4 pages - a small enough region to search +exhaustively. This mechanism is clearly expandable to larger NAND +devices - within reason. The RAM overhead with this approach is approx +2 bytes per page - 512kB of RAM for a whole 128MB NAND. + +Boot-time scanning to build the file structure lists only requires +one pass reading NAND. If proper shutdowns happen the current RAM +summary of the filesystem status is saved to flash, called +'checkpointing'. This saves re-scanning the flash on startup, and gives +huge boot/mount time savings. + +YAFFS regenerates its state by 'replaying the tape' - i.e. by +scanning the chunks in their allocation order (i.e. block sequence ID +order), which is usually different form the media block order. Each +block is still only read once - starting from the end of the media and +working back. + +YAFFS tags in YAFFS1 mode: + +18-bit Object ID (2^18 files, i.e. > 260,000 files). File id 0- is not + valid and indicates a deleted page. File od 0x3ffff is also not valid. + Synonymous with inode. +2-bit serial number +20-bit Chunk ID within file. Limit of 2^20 chunks/pages per file (i.e. + > 500MB max file size). Chunk ID 0 is the file header for the file. +10-bit counter of the number of bytes used in the page. +12 bit ECC on tags + +YAFFS tags in YAFFS2 mode: + 4 bytes 32-bit chunk ID + 4 bytes 32-bit object ID + 2 bytes Number of data bytes in this chunk + 4 bytes Sequence number for this block + 3 bytes ECC on tags + 12 bytes ECC on data (3 bytes per 256 bytes of data) + + +Page allocation and garbage collection + +Pages are allocated sequentially from the currently selected block. +When all the pages in the block are filled, another clean block is +selected for allocation. At least two or three clean blocks are +reserved for garbage collection purposes. If there are insufficient +clean blocks available, then a dirty block ( ie one containing only +discarded pages) is erased to free it up as a clean block. If no dirty +blocks are available, then the dirtiest block is selected for garbage +collection. + +Garbage collection is performed by copying the valid data pages into +new data pages thus rendering all the pages in this block dirty and +freeing it up for erasure. I also like the idea of selecting a block +at random some small percentage of the time - thus reducing the chance +of wear differences. + +YAFFS is single-threaded. Garbage-collection is done as a parasitic +task of writing data. So each time some data is written, a bit of +pending garbage collection is done. More pages are garbage-collected +when free space is tight. + + +Flash writing + +YAFFS only ever writes each page once, complying with the requirements +of the most restricitve NAND devices. + +Wear levelling + +This comes as a side-effect of the block-allocation strategy. Data is +always written on the next free block, so they are all used equally. +Blocks containing data that is written but never erased will not get +back into the free list, so wear is levelled over only blocks which +are free or become free, not blocks which never change. + + + +Some helpful info +----------------- + +Formatting a YAFFS device is simply done by erasing it. + +Making an initial filesystem can be tricky because YAFFS uses the OOB +and thus the bytes that get written depend on the YAFFS data (tags), +and the ECC bytes and bad block markers which are dictated by the +hardware and/or the MTD subsystem. The data layout also depends on the +device page size (512b or 2K). Because YAFFS is only responsible for +some of the OOB data, generating a filesystem offline requires +detailed knowledge of what the other parts (MTD and NAND +driver/hardware) are going to do. + +To make a YAFFS filesystem you have 3 options: + +1) Boot the system with an empty NAND device mounted as YAFFS and copy + stuff on. + +2) Make a filesystem image offline, then boot the system and use + MTDutils to write an image to flash. + +3) Make a filesystem image offline and use some tool like a bootloader to + write it to flash. + +Option 1 avoids a lot of issues because all the parts +(YAFFS/MTD/hardware) all take care of their own bits and (if you have +put things together properly) it will 'just work'. YAFFS just needs to +know how many bytes of the OOB it can use. However sometimes it is not +practical. + +Option 2 lets MTD/hardware take care of the ECC so the filesystem +image just had to know which bytes to use for YAFFS Tags. + +Option 3 is hardest as the image creator needs to know exactly what +ECC bytes, endianness and algorithm to use as well as which bytes are +available to YAFFS. + +mkyaffs2image creates an image suitable for option 3 for the +particular case of yaffs2 on 2K page NAND with default MTD layout. + +mkyaffsimage creates an equivalent image for 512b page NAND (i.e. +yaffs1 format). + +Bootloaders +----------- + +A bootloader using YAFFS needs to know how MTD is laying out the OOB +so that it can skip bad blocks. + +YAFFS Tracing +------------- diff --git a/fs/yaffs2/devextras.h b/fs/yaffs2/devextras.h new file mode 100644 index 0000000..f6e5361 --- /dev/null +++ b/fs/yaffs2/devextras.h @@ -0,0 +1,275 @@ +/* + * YAFFS: Yet another Flash File System .

The global sequence counter is incremented each time + * UBI writes a new VID header to the flash, i.e. when it maps a logical + * eraseblock to a new physical eraseblock. The global sequence counter is an + * unsigned 64-bit integer and we assume it never overflows. The @sqnum + * (sequence number) is used to distinguish between older and newer versions of + * logical eraseblocks. + * + * There are 2 situations when there may be more then one physical eraseblock + * corresponding to the same logical eraseblock, i.e., having the same @vol_id + * and @lnum values in the volume identifier header. Suppose we have a logical + * eraseblock L and it is mapped to the physical eraseblock P. + * + * 1. Because UBI may erase physical eraseblocks asynchronously, the following + * situation is possible: L is asynchronously erased, so P is scheduled for + * erasure, then L is written to,i.e. mapped to another physical eraseblock P1, + * so P1 is written to, then an unclean reboot happens. Result - there are 2 + * physical eraseblocks P and P1 corresponding to the same logical eraseblock + * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the + * flash. + * + * 2. From time to time UBI moves logical eraseblocks to other physical + * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P + * to P1, and an unclean reboot happens before P is physically erased, there + * are two physical eraseblocks P and P1 corresponding to L and UBI has to + * select one of them when the flash is attached. The @sqnum field says which + * PEB is the original (obviously P will have lower @sqnum) and the copy. But + * it is not enough to select the physical eraseblock with the higher sequence + * number, because the unclean reboot could have happen in the middle of the + * copying process, so the data in P is corrupted. It is also not enough to + * just select the physical eraseblock with lower sequence number, because the + * data there may be old (consider a case if more data was added to P1 after + * the copying). Moreover, the unclean reboot may happen when the erasure of P + * was just started, so it result in unstable P, which is "mostly" OK, but + * still has unstable bits. + * + * UBI uses the @copy_flag field to indicate that this logical eraseblock is a + * copy. UBI also calculates data CRC when the data is moved and stores it at + * the @data_crc field of the copy (P1). So when UBI needs to pick one physical + * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is + * examined. If it is cleared, the situation* is simple and the newer one is + * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC + * checksum is correct, this physical eraseblock is selected (P1). Otherwise + * the older one (P) is selected. + * + * Note, there is an obsolete @leb_ver field which was used instead of @sqnum + * in the past. But it is not used anymore and we keep it in order to be able + * to deal with old UBI images. It will be removed at some point. + * + * There are 2 sorts of volumes in UBI: user volumes and internal volumes. + * Internal volumes are not seen from outside and are used for various internal + * UBI purposes. In this implementation there is only one internal volume - the + * layout volume. Internal volumes are the main mechanism of UBI extensions. + * For example, in future one may introduce a journal internal volume. Internal + * volumes have their own reserved range of IDs. + * + * The @compat field is only used for internal volumes and contains the "degree + * of their compatibility". It is always zero for user volumes. This field + * provides a mechanism to introduce UBI extensions and to be still compatible + * with older UBI binaries. For example, if someone introduced a journal in + * future, he would probably use %UBI_COMPAT_DELETE compatibility for the + * journal volume. And in this case, older UBI binaries, which know nothing + * about the journal volume, would just delete this volume and work perfectly + * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image + * - it just ignores the Ext3fs journal. + * + * The @data_crc field contains the CRC checksum of the contents of the logical + * eraseblock if this is a static volume. In case of dynamic volumes, it does + * not contain the CRC checksum as a rule. The only exception is when the + * data of the physical eraseblock was moved by the wear-leveling unit, then + * the wear-leveling unit calculates the data CRC and stores it in the + * @data_crc field. And of course, the @copy_flag is %in this case. + * + * The @data_size field is used only for static volumes because UBI has to know + * how many bytes of data are stored in this eraseblock. For dynamic volumes, + * this field usually contains zero. The only exception is when the data of the + * physical eraseblock was moved to another physical eraseblock for + * wear-leveling reasons. In this case, UBI calculates CRC checksum of the + * contents and uses both @data_crc and @data_size fields. In this case, the + * @data_size field contains data size. + * + * The @used_ebs field is used only for static volumes and indicates how many + * eraseblocks the data of the volume takes. For dynamic volumes this field is + * not used and always contains zero. + * + * The @data_pad is calculated when volumes are created using the alignment + * parameter. So, effectively, the @data_pad field reduces the size of logical + * eraseblocks of this volume.
