SV6256P WiFi Now Working on Linux 6.x (Armbian Tested)

[Kevin su]

I’m really happy to share that I finally managed to port the SV6256P (SSV6X5X) SDIO Wi-Fi driver from the legacy Linux 4.4 kernel to modern kernels.

This repository contains my working port for Linux kernel 6.12 and newer, with updated mac80211/cfg80211 integration so the driver can build and run on recent Armbian systems.

The chipset is commonly used in many low-cost TV boxes and embedded devices, but the original driver only supported legacy kernels (4.4).

Now it’s functional again on modern systems, at least on my tested hardware (Allwinner H616 / X96 Q via SDIO).

I’m quite excited to finally see this old Wi-Fi chip working on a 6.x kernel 🙂

Hello, congratulations for your achievement!

 

I wonder if you had the chance to give a shot to the ssv6051 sibling... the original drivers (one for ssv6051 and another for ssv6x5x) were really a mess that @ilmich and me did a lot of work at the time to cleanup and fix things in the past time. We concentrated against the ssv6051 driver at the time and in fact the ssv6051 driver already works in mainline kernel (it is in the rockchip 32bit patch directory), although it is still quite a mess. Here it is the repository if you want to take a look to the commits.

 

We also started an attempt to do a clean and proper reimplementation of the ssv6xxx driver, but actually never went over firmware loading (the repo is private since it was a heavy WIP, but can share if you have enough will to take a look to that)
