@ -95,9 +95,28 @@ There are two possibilities:
TODO: adapt pacman sources such that the pkgs `linux` and `linux-headers` are installed from the local sources in `linux-pkgs`.
In order to install the linux headers needed to build modules from other packages you need to compile the kernel directly on the arm cpu. Boot into the system and clone the [main line kernel repository](https://github.com/torvalds/linux.git). Checkout the latest releas tag, copy corresponding config and apply corresponding patches.
In order to install the linux headers needed to build modules from other packages you need to compile the kernel directly on the arm cpu. Boot into the system and clone the [main line kernel repository](https://github.com/torvalds/linux.git). Checkout the latest release tag. Create a link to the linux repository and run makepkg:
```bash
cd kernel-pkgs
mkdir src
ln -s /path/to/linux/repo src/linux
makepkg
```
If everything finishes successfully install the created packages. Before that, backup original zImage and dtbs files!
```bash
sudo cp /boot/zImage /boot/zImage.orig
sudo cp /boot/dtbs/mt7623n-bananapi-bpi-r2.dtb /boot/dtbs/mt7623n-bananapi-bpi-r2.orig.dtb
sudo pacman -U linux-armv7-${version}-armv7h.pkg.tar.xz
sudo pacman -U linux-armv7-headers-${version}-armv7h.pkg.tar.xz
```
Advise pacman to ignore these two packages. Otherwise it will update them from the official mirrors, which will probably not work:
```bash
# /etc/pacman.conf
IgnorePkg = linux-armv7 linux-armv7-headers
```
