scripts/gen_initramfs_list.sh: Convert to a /bin/sh script

2011-05-12T14:48:39+00:00

Replace bashisms with POSIX-compatible shell scripting.

Notably, de-duplicate '/' using a sed command from elsewhere in the same script
rather than "${name//\/\///}".

initramfs: Use KBUILD_BUILD_TIMESTAMP for generated entries

2011-04-18T12:27:52+00:00

gen_init_cpio gets the current time and uses it for each symlink,
special file, and directory.  Grab the current time once and make it
possible to override it with the KBUILD_BUILD_TIMESTAMP variable for
reproducible builds.

The timestamps recorded in the .gz files add no value.

decompressors: add boot-time XZ support

2011-01-13T16:03:25+00:00

This implements the API defined in  which is
used for kernel, initramfs, and initrd decompression.  This patch together
with the first patch is enough for XZ-compressed initramfs and initrd;
XZ-compressed kernel will need arch-specific changes.

The buffering requirements described in decompress_unxz.c are stricter
than with gzip, so the relevant changes should be done to the
arch-specific code when adding support for XZ-compressed kernel.
Similarly, the heap size in arch-specific pre-boot code may need to be
increased (30 KiB is enough).

The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and
memzero() (memset(ptr, 0, size)), which aren't available in all
arch-specific pre-boot environments.  I'm including simple versions in
decompress_unxz.c, but a cleaner solution would naturally be nicer.

kbuild: Include gen_initramfs_list.sh and the file list in the .d file

2010-03-23T12:07:59+00:00

Expand the dependency set used for the initrd to include the
CONFIG_INITRAMFS_SOURCE file and the generator script itself.
Otherwise changing the initramfs file list does not rebuild the CPIO.

kbuild: fix spurious initramfs rebuild

2009-04-11T06:18:12+00:00

When gen_initramfs_list is used to generate make dependencies, it
includes symbolic links, for which make tracks the link target. Any
change to that target will cause an initramfs rebuild, even if the
symlink points to something outside of the initramfs directory.

If the target happens to be /tmp, the rebuild occurs for each kernel
build, since gen_initramfs_list uses mktemp...

Proposed way to fix it is to omit symbolic links from generated
dependencies, but this has a small drawback: changing perm/owner on a
symlink will go unnoticed.
