bzip2/lzma: quiet Kconfig warning for INITRAMFS_COMPRESSION_NONE

2009-04-01T06:51:56Z

Impact: quiet Kconfig warning It appears that Kconfig simply has no way to provide defaults for entries that exist inside a conditionalized choice block. Fortunately, it turns out we don't actually ever use CONFIG_INITRAMFS_COMPRESSION_NONE, so we can just drop it for everything outside the choice block. Signed-off-by: H. Peter Anvin

bzip2/lzma: don't ask for compression mode for the default initramfs

2009-03-29T00:27:15Z

Impact: Kconfig noise reduction, documentation The default initramfs is so small that it makes no sense to worry about the additional memory taken by not double-compressing it. Therefore, don't bug the user with it. Also, improve the description of the option, which was downright incorrect. Signed-off-by: H. Peter Anvin

bzip2/lzma: consistently capitalize LZMA in Kconfig

2009-03-28T23:10:59Z

Impact: message formatting Consistently spell LZMA in all capitals, since it (unlike gzip or bzip2) is an acronym. Signed-off-by: H. Peter Anvin

bzip2/lzma: clarify the meaning of the CONFIG_RD_ options

2009-03-28T23:09:48Z

Impact: Kconfig clarification Make it clear that the CONFIG_RD_* options are about what formats are supported, not about what formats are actually being used. Signed-off-by: H. Peter Anvin

bzip2/lzma: move CONFIG_RD_* options under CONFIG_EMBEDDED

2009-03-28T22:49:08Z

Impact: reduce Kconfig noise Move the options that control possible initramfs/initrd compressions underneath CONFIG_EMBEDDED. The only impact of leaving these options set to y is additional code in the init section of the kernel; there is no reason to burden non-embedded users with these options. Signed-off-by: H.

bzip2/lzma: make internal initramfs compression configurable

2009-02-19T21:43:51Z

Impact: Avoids silent environment dependency Make builtin initramfs compression an explicit configurable. The previous version would pick a compression based on the binaries which were installed on the system, which could lead to unexpected results. It is now explicitly configured, and not having the appropriate binaries installed on the build host is simply an error. Signed-off-by: Alain Knaff Signed-off-by: H. Peter Anvin

bzip2/lzma: fix built-in initramfs vs CONFIG_RD_GZIP

2009-01-07T08:10:27Z

Impact: Resolves build failures in some configurations Makes it possible to disable CONFIG_RD_GZIP . In that case, the built-in initramfs will be compressed by whatever compressor is available (bzip2 or lzma) or left uncompressed if none is available. It also removes a couple of warnings which occur when no ramdisk compression at all is chosen. It also restores the select ZLIB_INFLATE in drivers/block/Kconfig which somehow came missing. This is needed to activate compilation of the stuff in zlib_deflate. Signed-off-by: Alain Knaff Signed-off-by: H. Peter Anvin

bzip2/lzma: move initrd/ramfs options out of BLK_DEV

2009-01-07T08:03:49Z

Impact: Partial resolution of build failure Move the initrd/initramfs configuration options from drivers/block/Kconfig to usr/Kconfig, since they do not and should not depend on CONFIG_BLK_DEV. This fixes builds when CONFIG_BLK_DEV=n. Signed-off-by: H. Peter Anvin

kbuild: gen_init_cpio expands shell variables in file names

2008-12-03T20:32:03Z

Modify gen_init_cpio so that lines that specify files can contain what looks like a shell variable that's expanded during processing. For example: file /sbin/kinit ${RFS_BASE}/usr/src/klibc/kinit/kinit 0755 0 0 given RFS_BASE is "/some/directory" in the environment would be expanded to file /sbin/kinit /some/directory/usr/src/klibc/kinit/kinit 0755 0 0 If several environment variables appear in a line, they are all expanded with processing happening from left to right. Undefined variables expand to a null string. Syntax errors stop processing, letting the existing error handling show the user offending line. This patch helps embedded folks who frequently create several RFS directories and then switch between them as they're tuning an initramfs.

kbuild: add support for reading stdin with gen_init_cpio

2007-07-16T19:15:52Z

Treat an argument of "-" as meaning "read stdin for cpio files" so gen_init_cpio can be piped into. Signed-off-by: Mike Frysinger Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg
