In fact it would be very good to have this because the chip, Broadcom BCM4334, is used in a number of phones. Currently the only WLAN chipset with free firmware is the Atheros ath9k family and they (1) aren't used in mobile devices and (2) don't support newer standards such as 802.11ac. There was an effort to reverse engineer some earlier Broadcom chips: https://lwn.net/Articles/314313/ http://netweb.ing.unibs.it/~openfwwf/ However, the resulting firmware has only ever been experimental. The interest is from academia. For example, a 2014 paper from the OpenFWWF authors was titled "Emitter Localisation from Reception Timestamps in Asynchronous Networks": http://netweb.ing.unibs.it/~openfwwf/localisation/ The purpose there is research rather than building usable free firmware. > There is actually a lot of support for the device in mainline compared > to most other devices.

The S3 gets even *more* attractive from a free software point of view. > So in summary, there is still a lot of development effort necessary and > I would be very happy about contributions. Excellent work, I look forward to hearing more. I'll see if I can't at least test out your kernel tree at some point.
