Such modules that use library CRC-CCITT functions require M here. config CRC16 tristate "CRC16 functions" help This option is provided for the case where no in-kernel-tree modules require CRC16 functions, but a module built outside the kernel tree does. Such modules that use library CRC16 functions require M here. config CRC_T10DIF tristate "CRC calculation for the T10 Data Integrity Field" select CRYPTO select CRYPTO_CRCT10DIF help This option is only needed if a module that's not in the kernel tree needs to calculate CRC checks for use with the SCSI data integrity subsystem. config CRC_ITU_T tristate "CRC ITU-T V.41 functions" help This option is provided for the case where no in-kernel-tree modules require CRC ITU-T V.41 functions, but a module built outside the kernel tree does. Such modules that use library CRC ITU-T V.41 functions require M here. config CRC32 tristate "CRC32/CRC32c functions" default y select BITREVERSE help This option is provided for the case where no in-kernel-tree modules require CRC32/CRC32c functions, but a module built outside the kernel tree does. Such modules that use library CRC32/CRC32c functions require M here. config CRC32_SELFTEST bool "CRC32 perform self test on init" default n depends on CRC32 help This option enables the CRC32 library functions to perform a self test on initialization. The self test computes crc32_le and crc32_be over byte strings with random alignment and length and computes the total elapsed time and number of bytes processed. choice prompt "CRC32 implementation" depends on CRC32 default CRC32_SLICEBY8 help This option allows a kernel builder to override the default choice of CRC32 algorithm. Choose the default ("slice by 8") unless you know that you need one of the others. config CRC32_SLICEBY8 bool "Slice by 8 bytes" help Calculate checksum 8 bytes at a time with a clever slicing algorithm. This is the fastest algorithm, but comes with a 8KiB lookup table. Most modern processors have enough cache to hold this table without thrashing the cache. This is the default implementation choice. Choose this one unless you have a good reason not to. config CRC32_SLICEBY4 bool "Slice by 4 bytes" help Calculate checksum 4 bytes at a time with a clever slicing algorithm. This is a bit slower than slice by 8, but has a smaller 4KiB lookup table. Only choose this option if you know what you are doing. config CRC32_SARWATE bool "Sarwate's Algorithm (one byte at a time)" help Calculate checksum a byte at a time using Sarwate's algorithm. This is not particularly fast, but has a small 256 byte lookup table. Only choose this option if you know what you are doing. config CRC32_BIT bool "Classic Algorithm (one bit at a time)" help Calculate checksum one bit at a time. This is VERY slow, but has no lookup table. This is provided as a debugging option. Only choose this option if you are debugging crc32. endchoice config CRC7 tristate "CRC7 functions" help This option is provided for the case where no in-kernel-tree modules require CRC7 functions, but a module built outside the kernel tree does. Such modules that use library CRC7 functions require M here. config LIBCRC32C tristate "CRC32c (Castagnoli, et al) Cyclic Redundancy-Check" select CRYPTO select CRYPTO_CRC32C help This option is provided for the case where no in-kernel-tree modules require CRC32c functions, but a module built outside the kernel tree does. Such modules that use library CRC32c functions require M here. See Castagnoli93. Module will be libcrc32c. config CRC8 tristate "CRC8 function" help This option provides CRC8 function. Drivers may select this when they need to do cyclic redundancy check according CRC8 algorithm. Module will be called crc8. config AUDIT_GENERIC bool depends on AUDIT && !AUDIT_ARCH default y config RANDOM32_SELFTEST bool "PRNG perform self test on init" default n help This option enables the 32 bit PRNG library functions to perform a self test on initialization. # # compression support is select'ed if needed # config 842_COMPRESS tristate config 842_DECOMPRESS tristate config ZLIB_INFLATE tristate config ZLIB_DEFLATE tristate config LZO_COMPRESS tristate config LZO_DECOMPRESS tristate source "lib/xz/Kconfig" # # These all provide a common interface (hence the apparent duplication with # ZLIB_INFLATE; DECOMPRESS_GZIP is just a wrapper.) # config DECOMPRESS_GZIP select ZLIB_INFLATE tristate config DECOMPRESS_BZIP2 tristate config DECOMPRESS_LZMA tristate config DECOMPRESS_XZ select XZ_DEC tristate config DECOMPRESS_LZO select LZO_DECOMPRESS tristate # # Generic allocator support is selected if needed # config GENERIC_ALLOCATOR boolean # # reed solomon support is select'ed if needed # config REED_SOLOMON tristate config REED_SOLOMON_ENC8 boolean config REED_SOLOMON_DEC8 boolean config REED_SOLOMON_ENC16 boolean config REED_SOLOMON_DEC16 boolean # # BCH support is selected if needed # config BCH tristate config BCH_CONST_PARAMS boolean help Drivers may select this option to force specific constant values for parameters 'm' (Galois field order) and 't' (error correction capability). Those specific values must be set by declaring default values for symbols BCH_CONST_M and BCH_CONST_T. Doing so will enable extra compiler optimizations, improving encoding and decoding performance up to 2x for usual (m,t) values (typically such that m*t < 200). When this option is selected, the BCH library supports only a single (m,t) configuration. This is mainly useful for NAND flash board drivers requiring known, fixed BCH parameters. config BCH_CONST_M int range 5 15 help Constant value for Galois field order 'm'. If 'k' is the number of data bits to protect, 'm' should be chosen such that (k + m*t) <= 2**m - 1. Drivers should declare a default value for this symbol if they select option BCH_CONST_PARAMS. config BCH_CONST_T int help Constant value for error correction capability in bits 't'. Drivers should declare a default value for this symbol if they select option BCH_CONST_PARAMS. # # Textsearch support is select'ed if needed # config TEXTSEARCH boolean config TEXTSEARCH_KMP tristate config TEXTSEARCH_BM tristate config TEXTSEARCH_FSM tristate config BTREE boolean config INTERVAL_TREE boolean help Simple, embeddable, interval-tree. Can find the start of an overlapping range in log(n) time and then iterate over all overlapping nodes. The algorithm is implemented as an augmented rbtree. See: Documentation/rbtree.txt for more information. config GENERIC_PAGE_TABLE bool config RADIX_TREE_MULTIORDER bool config ASSOCIATIVE_ARRAY bool help Generic associative array. Can be searched and iterated over whilst it is being modified. It is also reasonably quick to search and modify. The algorithms are non-recursive, and the trees are highly capacious. See: Documentation/assoc_array.txt for more information. config HAS_IOMEM boolean depends on !NO_IOMEM select GENERIC_IO default y config HAS_IOPORT boolean depends on HAS_IOMEM && !NO_IOPORT default y config HAS_DMA boolean depends on !NO_DMA default y config DMA_VIRT_OPS bool depends on HAS_DMA && (!64BIT || ARCH_DMA_ADDR_T_64BIT) default n config CHECK_SIGNATURE bool config CPUMASK_OFFSTACK bool "Force CPU masks off stack" if DEBUG_PER_CPU_MAPS help Use dynamic allocation for cpumask_var_t, instead of putting them on the stack. This is a bit more expensive, but avoids stack overflow. config DISABLE_OBSOLETE_CPUMASK_FUNCTIONS bool "Disable obsolete cpumask functions" if DEBUG_PER_CPU_MAPS depends on BROKEN config CPU_RMAP bool depends on SMP config DQL bool # # Netlink attribute parsing support is select'ed if needed # config NLATTR bool # # Generic 64-bit atomic support is selected if needed # config GENERIC_ATOMIC64 bool config ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE def_bool y if GENERIC_ATOMIC64 config LRU_CACHE tristate config AVERAGE bool "Averaging functions" help This option is provided for the case where no in-kernel-tree modules require averaging functions, but a module built outside the kernel tree does.
