Subject: [Qemu-devel] [PATCH v3 0/4] Adding LZFSE compression support for DMG block driver.
Date: Mon, 5 Nov 2018 13:08:02 -0200 [thread overview]
Message-ID: <20181105150806.13649-1-jcfaracco@gmail.com> (raw)
Since Mac OS X El Capitain (v10.11), Apple uses LZFSE compression to
generate compressed DMGs as an alternative to BZIP2. Possible, Apple
want to keep this algorithm as default in long term. Some years ago,
Apple opened the LZFSE algorithm to opensource and the main source (or
the most active repo), can be found at: https://github.com/lzfse/lzfse
v1-v2: Fixing some error handlings from dmg-lzfse.c
v2-v3: Master rebasing suggestion from Stefan.
Julio Faracco (4):
block: adding lzfse decompressing support as a module.
configure: adding support to lzfse library.
dmg: including dmg-lzfse module inside dmg block driver.
dmg: exchanging hardcoded dmg UDIF block types to enum.
