397# Use xzkern to compress the kernel image and xzmisc to compress other things.
398#
399# xzkern uses a big LZMA2 dictionary since it doesn't increase memory usage
400# of the kernel decompressor. A BCJ filter is used if it is available for
401# the target architecture. xzkern also appends uncompressed size of the data
402# using size_append. The .xz format has the size information available at
403# the end of the file too, but it's in more complex format and it's good to
404# avoid changing the part of the boot code that reads the uncompressed size.
405# Note that the bytes added by size_append will make the xz tool think that
406# the file is corrupt. This is expected.
407#
408# xzmisc doesn't use size_append, so it can be used to create normal .xz
409# files. xzmisc uses smaller LZMA2 dictionary than xzkern, because a very
410# big dictionary would increase the memory usage too much in the multi-call
411# decompression mode. A BCJ filter isn't used either.
