Automated build and patch script for the Broadcom STA (wl) Wi-Fi driver on Alpine and Chimera Linux

To run it just

Clone the repo

git clone https://github.com/krenzelok/broadcom-wl-chimera-alpine.git

Change directory

cd broadcom-wl-chimera-alpine

Run it

./patchwl.sh

Manual installation

First get the required dependencies (Assuming you have linux-stable)

doas apk add linux-headers linux-stable-devel base-devel git wget

If you use alpine

doas apk add linux-headers linux-stable-dev build-base git wget

Clone the broadcom repo

git clone https://github.com/joanbm/broadcom-wl-linux-mainline.git

Change directory

cd broadcom-wl-linux-mainline

Run the extract and patch script

./extract_and_patch

Go inside the folder it made (My case its hybrid-v35_64-nodebug-pcoem-6_30_223_271)

cd hybrid-v35_64-nodebug-pcoem-6_30_223_271

Compile on chimera

make -C /lib/modules/$(uname -r)/build M=$(pwd) CC=clang

If on alpine

make -C /lib/modules/$(uname -r)/build M=$(pwd)

(Optional) check if the compiled driver is here

ls -l wl.ko

Now make a directory in modules

doas mkdir -p /lib/modules/$(uname -r)/extra

Now copy the newly compiled driver

doas cp wl.ko /lib/modules/$(uname -r)/extra/

Update the driver database

doas depmod -a

(Optional) check if modprobe recognizes it

modinfo wl

Note

If you rerun the script make sure to delete

broadcom-wl-linux-mainline

Because it git cannot fetch the repo when you have the folder

Also this is in testing so make sure to make an issue
