# --------------------------------------------------------------------------- |

# Use xzkern to compress the kernel image and xzmisc to compress other things. |
|
# |
|
# xzkern uses a big LZMA2 dictionary since it doesn't increase memory usage |
|
# of the kernel decompressor. A BCJ filter is used if it is available for |
|
# the target architecture. xzkern also appends uncompressed size of the data |
|
# using size_append. The .xz format has the size information available at |
|
# the end of the file too, but it's in more complex format and it's good to |
|
# avoid changing the part of the boot code that reads the uncompressed size. |
|
# Note that the bytes added by size_append will make the xz tool think that |
|
# the file is corrupt. This is expected. |
|
# |
|
# xzmisc doesn't use size_append, so it can be used to create normal .xz |
|
# files. xzmisc uses smaller LZMA2 dictionary than xzkern, because a very |
|
# big dictionary would increase the memory usage too much in the multi-call |
|
# decompression mode. A BCJ filter isn't used either. |
