#8783 closed enhancement (fixed)

xz compression for squashfs in 2.6.38+

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: Cc:

Description

The new kernel 2.6.38 features xz compression for squashfs, it would be nice to get some more free space when compressing the kernel (also see /ticket/8781.html) and the filesystem.

Maybe there is also the possibility to backport this enhancement to older kernels, see https://lkml.org/lkml/2011/1/15/152

Hello anonymous,
There is already possibility to use XZ compression for squashfs image. See https://dev.openwrt.org/changeset/26422/trunk
I have tested it for kernel 2.6.39 and it is working. You just need to make sure to have enabled CONFIG_SQUASHFS_XZ=y in your kernel config.

I dont know the status for 2.6.38. XZ has been disabled in https://dev.openwrt.org/changeset/26193/trunk as in that time there was no use for it. Maybe there is time to enable it.
