In case you are building a kernel version >= 5.8, make sure you have installed at least [dwarves >= 1.16.0](https://packages.debian.org/bullseye/dwarves). In case you are building a kernel version >= 5.8, make sure you have installed at least [dwarves >= 1.16.0](https://packages.debian.org/buster-backports/dwarves).
Unfortunately, this version is currently only available in the Debian Testing and Debian Unstable repositories. To work around this issue, we describe two options: Unfortunately, this version is not available in the Debian Buster repositories, so you will have to install it from the buster-backports repository:
1. You may add the Debian Testing repository to your APT sources as described [here](https://serverfault.com/a/382101) and install the newer `dwarves` package as follows: ```bash
```shell echo deb http://ftp.de.debian.org/debian buster-backports main >> /etc/apt/sources.list
apt install -t testing dwarves apt update
``` apt install dwarves=1.19-1~bpo10+1
2. Alternatively, you may [download](https://packages.debian.org/bullseye/dwarves) the newer `dwarves` (>= 1.16) package from the Debian website and install the package manually, for example:
```shell
wget http://ftp.us.debian.org/debian/pool/main/d/dwarves-dfsg/dwarves_1.17-1_amd64.deb
apt install ./dwarves_1.17-1_amd64.deb
``` ```
Or whatever version is available in backports when you are reading this guide.
#### Obtaining the source #### Obtaining the source
```bash ```bash
git clone https://github.com/fabianishere/pve-edge-kernel git clone https://github.com/fabianishere/pve-edge-kernel
cd pve-ede-kernel cd pve-ede-kernel
git checkout v5.11.x
git submodule update --init --depth=1 --recursive submodules/ubuntu-mainline git submodule update --init --depth=1 --recursive submodules/ubuntu-mainline
git submodule update --init --recursive git submodule update --init --recursive
``` ```
Afterwards, select the branch of your likings (e.g. `v5.8.x`). You can select the branch of your likings by changing `v5.11.x`. This will automatically select the last patchversion for the minor version you have chosen. If you wan to select the patchversion too, you can check the [available tags](https://github.com/fabianishere/pve-edge-kernel/tags), for example `git checkout v5.11.8-1`.
