Subject: [Call for Testers] Modern rtw88 port for RTL8723BS (SDIO)

[Luka Gejak]

Hi everyone,

I have been working on a standalone, out-of-tree port of the rtw88 driver specifically for the RTL8723BS (SDIO) chipset. As many of you know, the RTL8723BS is still technically in the "staging" directory in the mainline kernel (rtl8723bs). My goal was to bring this hardware into the modern mac80211 framework by backporting the rtw88 core and implementing the 8723B-specific PHY logic.

What’s implemented:

Full integration with the rtw88 core framework.
PHY/Calibration: Implemented IQK calibration and thermal-based TX power tracking.
Build System: Clean, standalone Makefile that supports automated KDIR detection.
Validation: Code passes make C=1 (Sparse) and includes a basic validation script.

The Catch:
I do not currently have the physical hardware (RTL8723BS) to perform a "live" test. I am looking for volunteers who have devices using this chip (common in Intel Atom tablets/sticks) to see if the modules load and can successfully scan/associate with APs.

Repository:
https://github.com/MocLG/rtw88-rtl8723bs

How to help:

Clone the repo and run make. Follow the loading order in the README. Share your dmesg | grep rtw88 output in the GitHub Issues.
I'd appreciate any feedback on stability or range compared to the legacy staging driver!
