Atheros Hardware Abstraction Layer Source Is Released

chrb writes "With the recent discussion here on proprietary blobs in the Linux kernel, it's nice to see that today Sam Leffler has released the source for the Atheros Hardware Abstraction Layer under the ISC license, which is both GPL and BSD compatible. The Atheros chipset is used in many laptops, so this is another important step towards running a completely free distribution."

This is interesting, as there are three Atheros drivers, all different. Madwifi uses the HAL. Ath5 is in the Linux trunk and doesn't (I think). Ath9 was developed by Atheros and probably uses the HAL but I didn't check. Sam was mostly interested in this because he wanted to work on mesh networking - it's good to see he's still involved.

The argument about BLOBs - binary loadable objects in the kernel - is not new, despite Bruce Byfield's recent report. I guess he just doesn't read the kernel list and other distro internal discussions, where this has been going on for a decade. And FSF did not "redefine" anything, they've always held that opinion.

It would be nice to draw a line at the hardware bus, with all above that Open Source and all below that whatever the hardware manufacturer likes because we don't deal with it. But BLOBs break that, because they are both above and below the bus. If we're going to handle the code, we can't really deny that there's a computer there running closed-source code. And given the degree to which wifi firmware sucks the world would be nicer if it was Free Software. Now, we just have to drive some sense into FCC, etc.
