The branch stable/14 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=a2d1e07f6451fa5d1803e6dba819db2020bf1c31 commit a2d1e07f6451fa5d1803e6dba819db2020bf1c31 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2023-04-18 15:17:41 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2024-10-16 21:49:29 +0000 rtw89: add man page and hook driver up to the build After two years, add the initial man page and hook Realteks rtw89 driver up to the build for more people to test given successful reports. devd.conf is already providing support based on the rtw<n+> regex. The driver uses the LinuxKPI compat layer. Firmware is provided by ports: net/wifi-firmware-rtw89-kmod or one of the flavours. People are advised to used fwget(8) to automatically install the correct firmware for their chipset. Please note that for the moment the driver requires a tunable to be set in loader.conf: compat.linuxkpi.skb.mem_limit=1 Many thanks to everyone who in the last two years helped testing, debugged, submitted patches to get the driver to this stage where initial functionality seems working.
