Ubuntu22.04@WSL2でKernel ConfigしてBluetooth動いたよメモ

Last updated at Posted at 2023-01-06

前提

  • たぶんWin11 + WSL2じゃないとだめ
  • windows側でusbipをインストールしている
  • usbipd wsl attach --busid BUS-ID を実行している
  • lsusbでデバイスが認識されている
  • 僕が試したのはIntel AX200

カーネルコンパイル

$ uname --kernel-release
5.15.79.1-microsoft-standard-WSL2+
$ git clone --filter=blob:none https://github.com/microsoft/WSL2-Linux-Kernel
$ cd WSL2-Linux-Kernel
$ git checkout -b tag-5.15.79.1 refs/tags/linux-msft-wsl-5.15.79.1
$ zcat /proc/config.gz | sudo tee .config >/dev/null
$ make menuconfig #下に抜き出し
$ sudo make -j$(nproc)
$ sudo make modules_install
$ sudo make install -j 16
$ ls /lib/modules/
# 5.15.79.1-microsoft-standard-WSL2+ が出来ているはず
# カーネルをWindows側にコピー
cp ./vmlinux /mnt/c/tmp/wsl2-kernel/vmlinux

menuconfig

一応抜き出したけど↑を参照した方が良いと思います
