pie scheduler for aqmt

This repository contains the PIE scheduler from Linux patched so it can be used with https://github.com/henrist/aqmt

Using

When building, we need to add the common directory of the aqmt repository to the inclusion path.

Building:

CPATH=/path/to/aqmt/common make

Loading kernel module:

sudo make load

The scheduler will now be available as a qdisc with the name pie. Note that if you had pie available already this will shadow that module, so this will be used instead.

Unloading:

sudo make unload

Keeping up-to-date with kernel changes

The branch kernel-reference contains copies of commits from the Linux kernel. This is merged into master to produce the latest patched version.

To update:

# produce patches
cd path-to-linux-tree
cd net/sched
# modify the range to fit
git format-patch -o /tmp/sched e5a4b17da..HEAD -- sch_pie.c

# update this repo
git checkout kernel-reference
git am -p3 /tmp/sched/*.patch
git checkout master
git merge kernel-reference

Push both branches after reviewing.
