This saves mount time, but makes the first look-up - a bit longer. - - Lazy loading will only happen if enabled by this option being 'n' - and if the appropriate tags are available, else yaffs2 will - automatically fall back to immediate loading and do the right - thing. - - Lazy laoding will be required by checkpointing. - - Setting this to 'y' will disable lazy loading. - - If unsure, say N. - -config YAFFS_CHECKPOINT_RESERVED_BLOCKS - int "Reserved blocks for checkpointing" - depends on YAFFS_YAFFS2 - default 10 - help - Give the number of Blocks to reserve for checkpointing. - Checkpointing saves the state at unmount so that mounting is - much faster as a scan of all the flash to regenerate this state - is not needed. These Blocks are reserved per partition, so if - you have very small partitions the default (10) may be a mess - for you. You can set this value to 0, but that does not mean - checkpointing is disabled at all. There only won't be any - specially reserved blocks for checkpointing, so if there is - enough free space on the filesystem, it will be used for - checkpointing. - - If unsure, leave at default (10), but don't wonder if there are - always 2MB used on your large page device partition (10 x 2k - pagesize). When using small partitions or when being very small - on space, you probably want to set this to zero. - -config YAFFS_DISABLE_WIDE_TNODES - bool "Turn off wide tnodes" - depends on YAFFS_FS - default n - help - Wide tnodes are only used for NAND arrays >=32MB for 512-byte - page devices and >=128MB for 2k page devices. They use slightly - more RAM but are faster since they eliminate chunk group - searching. - - Setting this to 'y' will force tnode width to 16 bits and save - memory but make large arrays slower. - - If unsure, say N. - -config YAFFS_ALWAYS_CHECK_CHUNK_ERASED - bool "Force chunk erase check" - depends on YAFFS_FS - default n - help - Normally YAFFS only checks chunks before writing until an erased - chunk is found. This helps to detect any partially written - chunks that might have happened due to power loss. - - Enabling this forces on the test that chunks are erased in flash - before writing to them. This takes more time but is potentially - a bit more secure. - - Suggest setting Y during development and ironing out driver - issues etc. Suggest setting to N if you want faster writing. - - If unsure, say Y. - -config YAFFS_SHORT_NAMES_IN_RAM - bool "Cache short names in RAM" - depends on YAFFS_FS - default y - help - If this config is set, then short names are stored with the - yaffs_Object. This costs an extra 16 bytes of RAM per object, - but makes look-ups faster. - - If unsure, say Y. |
