2010-01-11Add LZO compression support for initramfs and old-style initrdAlbin Tonnerre1-5/+21

2009-03-31bzip2/lzma: quiet Kconfig warning for INITRAMFS_COMPRESSION_NONEH. Peter Anvin1-14/+1
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 <hpa@zytor.com>
2009-03-28bzip2/lzma: don't ask for compression mode for the default initramfsH. Peter Anvin1-10/+22
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 <hpa@zytor.com>
2009-03-28bzip2/lzma: consistently capitalize LZMA in KconfigH. Peter Anvin1-3/+3
Impact: message formatting Consistently spell LZMA in all capitals, since it (unlike gzip or bzip2) is an acronym. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2009-03-28bzip2/lzma: clarify the meaning of the CONFIG_RD_ optionsH. Peter Anvin1-3/+3
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 <hpa@zytor.com>
2009-03-28bzip2/lzma: move CONFIG_RD_* options under CONFIG_EMBEDDEDH. Peter Anvin1-8/+8
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. Peter Anvin <hpa@zytor.com>
2009-02-19bzip2/lzma: make internal initramfs compression configurableAlain Knaff1-0/+62
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 <alain@knaff.lu> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
2009-01-07bzip2/lzma: move initrd/ramfs options out of BLK_DEVH. Peter Anvin1-0/+27
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 <hpa@zytor.com>

2005-08-10kconfig: move initramfs options to General SetupSam Ravnborg1-0/+46
Move initramfs options from Device Drivers | Block Drivers to General Setup This is a more natural place for this option. Furthermore separate out intramfs options to usr/Kconfig Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
