Add LZ4 support |
[FFe] Add LZ4 support to initramfs-tools |
|
2018-04-17 14:17:06 |
Balint Reczey |
description |
I found that I could enable LZ4 compression for initramfs on my vivid machine by installing liblz4-tool package, adding one line to mkinitramfs and installing a kernel compiled with CONFIG_CRYPTO_LZ4=y.
Please include support for (legacy) LZ4.
Attached patch includes changes made to the latest version (initramfs-tools_0.120ubuntu3). |
Feature Freeze Justification
============================
Initramfs-tools uses gzip compression by default which served us well
for quite some time but LZ4 offers way faster decompression while
making a only slightly bigger initramfs files.
Having lz4 supported by initramfs-tools would allow users to opt-in for faster boot in Bionic from day 1.
On my old laptop the initramfs extraction time decreased from ~1.2s to ~0.24s:
(with lz4)
kernel: [ 0.285692] Unpacking initramfs...
kernel: [ 0.518806] Freeing initrd memory: 65148K
kernel: [ 0.289731] Unpacking initramfs...
kernel: [ 0.522823] Freeing initrd memory: 65148K
(with gzip)
kernel: [ 0.273748] Unpacking initramfs...
kernel: [ 1.490066] Freeing initrd memory: 57140K
kernel: [ 0.281729] Unpacking initramfs...
kernel: [ 1.498493] Freeing initrd memory: 57140K
Discussion on ubuntu-devel:

IMO the attached patch is minimally intrusive and it is safe to make this change even at this late hour of the release cycle.
