ath5k is a completely FOSS wireless driver for ar5000 Atheros based chipsets. It is now part John's of wireless-dev branch


Hacking ath5k

ath5k is currently only available through the ath5k branch of wireless-dev.

Here is a quick primer on git you can use to start hacking on ath5k.

To get ath5k:

git-clone git://
cd wireless-dev
# Create a local "branch" called 'ath5k' based on John's remote 'origin/ath5k'
git checkout -b ath5k origin/ath5k

To get latest updates you can do:

# Go back to the local master branch
git-checkout master
git-checkout ath5k
git-rebase origin/ath5k
# To review the changes last registered:
# To review the changes made to ath5k, with a diff:
git-log -p drivers/net/wireless/ath5k*

To hack on stuff, you can create your own branch by doing:

git-checkout -b ath5k-fix-foo origin/ath5k
# hack hack hack
# To get a diff of your work:
git-diff > my_changes.diff
# Or if you just want to read them:
# To revert to the original state of the branch:
git-checkout -f
# If instead you want to commit
git-commit -a
# To view local branches
git-branch -l
# To view all remote branches
git-branch -r

Other cool git stuff:

# get the SHA of two commits
# Then get the diff of them, by showing the logs in between
git-log -p d8a285c8f83f728be2d056e6d4b0909972789d51..9202ec15da36ca060722c363575e0e390d85fb71
# Since SHAs are pretty unique you can just give it a short version
# and it will try to match what is right:
git-log -p d8a28..9202e

Now say I have two local branches, and I want to merge them. If I'm on local branch ath5k-my-latest and I want to merge with local branch ath5k-fix-foo, I do:

git-pull . ath5k-fix-foo
