KeyStream was a small Japanese startup focusing on mobile Wi-Fi chips, their first and only main product being the KS3021 RF chip and the KS7010 Wi-Fi baseband chip. They were acquired by Renesas in April 2009, and are now continuing as the KeyStream brand inside Renesas. The technology will probably appear in other Renesas chips in the future.
Known users of these chips are:
- Microsoft Zune 30, and probably other Zune models as well
- Spectec SDW-821 full-size SD (SDIO) Wi-Fi card
- Spectec SDW-823 microSD (SDIO) Wi-Fi card
- (note that all other Spectec Wi-Fi cards have MTK Wi-Fi chips without Linux drivers!)
In October 2009, Renesas released driver sources licensed under the GPL (version 007 for Linux 2.6.24), and a binary firmware (v0.2f), available at ks7010_sdio_v007.tar.bz2.
TODO:
- up-level the driver to a more recent Linux kernel, for example 2.6.31 in our OpenWrt-XBurst tree.
- determine the exact feature set of the driver
- cleanup the driver sources and get upstream feedback
