broadcom-wl-aerynos

Broadcom Linux hybrid wireless driver (64-bit)

This project fetch the source from the archlinux package and buid for AerynOS.

The driver is for Broadcom BCM43xx 802.11 wireless devices. and the package well upload to the AerynOS repository. Install the package by

sudo moss install broadcom-wl

How to build this project

# find the version from the archlinux repository before you going.
$ sh fetch-source.sh 6.30.223.271-42

# auto build and package
$ sh autobuild-package.sh

Do every thing by hand.

Warning : AerynOS is designed in some spectial way, install any thing into /usr may be lost after the system update.

If you want install by hand, you can do like this:

1) Prerequisites

The following kernel modules are incompatible with this driver and should not be loaded:

• bcm43xx
• ssb
• b43
• ndiswrapper
• brcm80211
• bcma
• brcmsmac

Make sure to unload (rmmod command) and blacklist those modules in order to prevent them from being automatically reloaded during the next system startup:

/etc/modprobe.d/50-broadcom-wl-blacklist.conf

# wireless drivers (conflict with Broadcom hybrid wireless driver 'wl')
blacklist bcm43xx
blacklist ssb
blacklist b43
blacklist ndiswrapper
blacklist brcm80211
blacklist bcma
blacklist brcmsmac

2) Prepare the install location

As the AerynOS's /usr is totally controlled by the system, we need to install the driver to /usr/local, the /usr/local is link to /var/local in AerynOS.

Set the INSTALL_MOD_PATH to /usr/local in /etc/environment.d/10-external-mod.conf, and patch in the Makefile:

patch -p1 < 001-makefile.patch

the final install location is /usr/local/lib/modules/6.13.10-93.desktop/kernel/drivers/net/wireless/wl.ko.

3) Build the driver

The AerynOS use clang as the default compiler, and ld.lld as the linker.

$ make clean
$ make CC=clang LD=ld.lld V=1

4) Install the driver and configure the driver

$ sudo make install
$ depmod -A -b /usr/local
# try to load the module
$ modprobe wl

Put imcompatible modules in the blacklist:

/etc/modprobe.d/50-wl.conf

blacklist b43
blacklist ssb
blacklist cordic
blacklist bcma
# config wl use the /usr/local
install wl /sbin/modprobe -d /usr/local -i wl

Now config automatically load module:

$ echo "wl" | sudo tee /etc/modules-load.d/wl.conf

5) Check the driver

reboot

After reboot, check the driver:

$ modinfo -b /usr/local wl
