In this version, Some codes are fixed and more description and note are added. I would like to thank David Sterba for his review. The Last patch[5/5] of the patch set is for making x86 and arm default to LZ4-compressed for testing the LZ4 code in the linux-next. It was requested by Andrew Morton in the patch set v2. Currently, A preliminary version of LZ4 de/compression tool is supported. However, It is expected that we will have a tool with more features once its format is finished. LZ4 compression tool is available at http://code.google.com/p/lz4/source/checkout. Thanks, Kyungsik Change log: v2 - Clean up code - Enable unaligned access for ARM v6 and above with CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS - Add lz4_decompress() for faster decompression with uncompressed output size - Use lz4_decompress() for LZ4-compressed kernel during boot-process - Apply -Os to decompress.o to improve decompress performance during boot-up process Change log: v3 - Prevent double evaluation by using an inline function - Add LZ4 description and note for uncompressed chunk size issue - Fix indentation error Kyungsik Lee (5): decompressor: Add LZ4 decompressor module lib: Add support for LZ4-compressed kernel arm: Add support for LZ4-compressed kernel x86: Add support for LZ4-compressed kernel Kconfig: Make x86 and arm kernels default to the LZ4-compressed arch/arm/Kconfig | 1 + arch/arm/boot/compressed/.gitignore | 1 + arch/arm/boot/compressed/Makefile | 6 +- arch/arm/boot/compressed/decompress.c | 4 + arch/arm/boot/compressed/piggy.lz4.S | 6 + arch/x86/Kconfig | 1 + arch/x86/boot/compressed/Makefile | 5 +- arch/x86/boot/compressed/misc.c | 4 + include/linux/decompress/unlz4.h | 10 ++ include/linux/lz4.h | 51 ++++++ init/Kconfig | 19 +- lib/Kconfig | 7 + lib/Makefile | 2 + lib/decompress.c | 5 + lib/decompress_unlz4.c | 187 +++++++++++++++++++ lib/lz4/Makefile | 1 + lib/lz4/lz4_decompress.c | 326 ++++++++++++++++++++++++++++++++++ lib/lz4/lz4defs.h | 94 ++++++++++ scripts/Makefile.lib | 5 + usr/Kconfig | 9 + 20 files changed, 740 insertions(+), 4 deletions(-) create mode 100644 arch/arm/boot/compressed/piggy.lz4.S create mode 100644 include/linux/decompress/unlz4.h create mode 100644 include/linux/lz4.h create mode 100644 lib/decompress_unlz4.c create mode 100644 lib/lz4/Makefile create mode 100644 lib/lz4/lz4_decompress.c create mode 100644 lib/lz4/lz4defs.h -- 1.8.1.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
