Introduction
The linux-tiny patchset is a series of patches against the 2.6 mainline Linux kernel to reduce its memory and disk footprint, as well as to add features to aid working on small systems. Target users are developers of embedded system and users of small or legacy machines such as 386s and handhelds.
To the degree possible, the patchset should serve as a staging ground for patches, until they can be mainlined. Therefore, over time the set of patches in the set will fluctuate as new patches are submitted, and other patches are mainlined.

Linux-tiny Presentation by Matt Mackall, delivered at CELF's Technical Conference in 2005.
Original Announcements and e-mail
The original (Dec 11, 2003) announcement about the patchset, to the kernel mailing list, is available here:
Here are some other announcements from Matt Mackall to LKML:
Recent discussion thread on lkml is summarized at: LKML Thread Summary The thread is available at here
Note that currently, the smallest kernel that is reported in this thread is 197K compressed.
Download
Last release (for 2.6.22.5)
A recent Linux-tiny patchset release is available here: Media:Tiny-quilt-2.6.22.5-1.tar.gz
Installation Instructions
These instructions were for the Linux-tiny release for 2.6.22.5. Adjust accordingly for a different kernel version.
To apply the above patches, you need the referenced kernel (2.6.22) and quilt. Follow these steps:
- wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.tar.bz2
- tar -xjf linux-2.6.22.tar.bz2
- wget http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.22.5.bz2
- wget http://elinux.org/images/7/79/Tiny-quilt-2.6.22.5-1.tar.gz
- cd linux-2.6.22
- bzcat ../patch-2.6.22.5.bz2 | patch -p1
- tar -xzf ../Tiny-quilt-2.6.22-5-1.tar.gz
- quilt push -a
- cd ..
- mv linux-2.6.22 linux-2.6.22.5-tiny1
Auxiliary tools
Here is a short shell script for making a tiny-quilt release: Media:release-tiny
Older releases
- Linux 2.6.22.1:
- Linux 2.6.16.19
- broken-out patchset: 2.6.16.19-tiny1-broken-out
- Porting notes: notes
- Linux 2.6.0 to 2.6.14:
- Older Linux-tiny patchsets can be downloaded from: Linux Tiny Patchset
Test Project and Results
The CELF System Size working group has worked extensively with the Linux-tiny patch set. There is a script to produce a report of size reductions for the individual patches in the patchset, and results from various vendors about their use of Linux-tiny. See Linux Tiny Test Project
There are some miscellaneous usage notes at: Linux Tiny Notes
License
The Linux-tiny patches apply against the Linux kernel, and are provided under the GNU General Public License (GPL), version 2 only [1]. (This is the same license as the Linux kernel.)
