  • 6a108a14f   kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT ... Browse Code »

    The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
    is used to configure any non-standard kernel with a much larger scope than
    only small devices.

    This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
    references to the option throughout the kernel. A new CONFIG_EMBEDDED
    option is added that automatically selects CONFIG_EXPERT when enabled and
    can be used in the future to isolate options that should only be
    considered for embedded systems (RISC architectures, SLOB, etc).

    Calling the option "EXPERT" more accurately represents its intention: only
    expert users who understand the impact of the configuration changes they
    are making should enable it.

  • 3ebe12439   decompressors: add boot-time XZ support ... Browse Code »

    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.

  • ab76f3d77   bzip2/lzma: make internal initramfs compression configurable ... Browse Code »

    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.
