Candela Technologies for example has access to the QCA wifi firmware source code for the QCA Wifi 5 AP chips. They provide custom builds here: https://www.candelatech.com/ath10k.php
I know of one other company.
I do not know if they also have access to the driver source code, but I assume so. Silicon vendors often do not care about small customers, small is probably less than 250k units per year. If you are a customer which is expected to generate more than 5% of the revenue for the complete product line or the business unit then you get good support from these companies. The proprietary Broadcom Wifi driver was leaked multiple times by some companies which did not run the script to clean a GPL tar, but did something on their own and forgot to remove the Boardcom wifi driver source code. Last time I saw this was already 8 years ago. The Broadcom proprietary Wifi driver also contained the source code of the firmware running on the ARM chip inside the Wifi IP, at least it did this some time ago. For the Qualcomm 5G modem and the graphics driver this is probably different. |
