Download compat-wireless

git clone https://github.com/mcgrof/compat-wireless.git
git clone https://github.com/mcgrof/compat.git

Fetch o11s kernel

git clone git://github.com/cozybit/open80211s.git

Required Tools

• quilt (for refreshing)
• realpath

Generate Archive

Use this script in the directory above:

#!/bin/bash -e

dir=$(realpath $(dirname $0))

export GIT_TREE=$dir/open80211s
export GIT_COMPAT_TREE=$dir/compat

cd compat-wireless
./scripts/admin-update.sh
cd ..

tar cfvj compat-wireless-o11s.tar.bz2 compat-wireless

It is possible that admin-update.sh fails to apply some patches. In this case, run './scripts/admin-update.sh refresh', and use the quilt tool to refresh the compat-wireless patches against open80211s.

• If the hunk that fails applies to a driver that you are not interested in, just delete the hunk from the patch.
• If the entire patch applies to drivers that you are not interested in, delete the entire patch.

Then remember to run ./scripts/driver-select <your_driver_of_interest_here> to avoid running into build errors for other drivers.

A recent build of compat-wireless based on our 0.5 release is available here. Note:This compat-wireless build probably only works with ath9k, ath9k_htc and ath5k drivers. See below on how to build just the ath9k drivers.

Limited Testing

compat-wireless is designed to compile on a wide range of kernel versions. We did not test all of them. In fact, we only tested Ubuntu 9.10, 10.04.3 and 10.10

Notes

If you need to support multiple drivers from different vendors, the driver-select.sh script provided by compat-wireless won't let you do it. A work around:

 1. ./scripts/driver-select iwlagn
 2. make install
 3. edit Makefile:

 - install: uninstall install-modules install-scripts
 + install: install-modules install-scripts

 4. ./scripts/driver-select ath
 5. make install

Test:

 6. ls /lib/modules-${KERNEL_VERSION}/updates/drivers/net/wireless/*
 And confirm that both drivers show up.

If this works for you, please share your success with the mailing list.
