  • 33e2a4227   lib/decompress.c add __init to decompress_method and data ... Browse Code »

    Fix the warning:

    WARNING: vmlinux.o(.text+0x14cfd8): Section mismatch in reference from the variable compressed_formats to the function .init.text:gunzip()
    The function compressed_formats() references
    the function __init gunzip().
    etc..

    Within decompress.c, compressed_formats[] needs 'a __initdata annotation',
    because some of it's data members refer to functions which will be
    unloaded after init.

    Consequently, its user decompress_method() will get the __init prefix.

  • 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.
