![]() ![]() Now that my efforts on FreeBSD/Broadcom Wi-Fi support have progressed far enough to be generally useful, I wanted to take some time to provide a brief overview of Broadcom's Wi-Fi hardware, and explain how my work provides a foundation for further FreeBSD Broadcom Wi-Fi/SoC improvements. With these changes in place, I was finally able to port the existing bwn(4) Broadcom SoftMAC Wi-Fi driver to the bhnd(4) bus, and implement initial support for the BCM43224 and BCM43225 chipsets, with additional hardware support to be forthcoming. ![]() Thanks to the generosity of the FreeBSD Foundation, I've recently finished implementing the necessary improvements to the bhnd(4) driver family. Since 2015, I've been working on improving FreeBSD support for Broadcom Wi-Fi devices and SoCs, including authoring the bhnd(4) driver family, which provides a unified bus and driver programming interface for these devices.įirst committed in early 2016, bhnd(4) allowed us to quickly bring up FreeBSD/MIPS on Broadcom SoCs, but it has taken much longer to implement the full set of features required to support modern Broadcom SoftMAC Wi-Fi hardware.
