wsl2-android-binder-kernel

Auto-built WSL2 kernel with Android binder support, for use with Waydroid.

Tracks microsoft/WSL2-Linux-Kernel releases and applies the minimum config changes needed for Android binder.

What it adds

CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDERFS=y
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"

Everything else is stock Microsoft WSL2 kernel config.

Installation

1. Download bzImage and modules.tar.gz from the latest release
2. Save bzImage somewhere stable, e.g. C:\Users\YourName\wsl-kernel\bzImage
3. Add to C:\Users\YourName\.wslconfig:

   [wsl2]
   kernel=C:\\Users\\YourName\\wsl-kernel\\bzImage

4. Run wsl --shutdown then relaunch your distro
5. Install kernel modules inside WSL (needed for networking and binder):

   sudo tar -xzf modules.tar.gz -C /lib/modules/
   sudo depmod -a

6. Verify modules load and binder is present:

   sudo modprobe bridge
   sudo modprobe dummy
   ls /dev/binder

Builds

• Automatic: runs daily, builds only when Microsoft ships a new kernel version
• Manual: use the Actions tab > "Build WSL2 Kernel with Android Binder" > "Run workflow" — optionally specify a tag to build an older version
• Releases: each Microsoft kernel version gets its own tagged release (e.g. linux-msft-wsl-6.6.123.2-binder), plus latest always points to the most recent build
