Enable Binder IPC on Arch Linux
Arch Linux provides an easy way to enable Binder IPC support through the linux-zen kernel, which already includes all necessary Binder components.
Install linux-zen Kernel
The linux-zen kernel is the recommended and simplest method to get Binder IPC support on Arch Linux:
# Update system packages
$ sudo pacman -Syu
# Install linux-zen kernel and headers
$ sudo pacman -S linux-zen linux-zen-headers
# Update bootloader configuration
$ sudo grub-mkconfig -o /boot/grub/grub.cfg
# Reboot to use the new kernel
$ sudo reboot
After reboot, select the zen kernel from the GRUB menu or set it as default.
Verification
After installing and booting into the zen kernel, verify Binder support is available:
# Check current kernel
$ uname -r
# Should show something like "6.x.x-zen1-1-zen"
Install rsbinder-tools
Install the rsbinder development tools:
# Install Rust (if not already installed)
$ sudo pacman -S rustup
$ rustup default stable
# Install rsbinder-tools from crates.io
$ cargo install rsbinder-tools
Create and Test Binder Device
Create a binder device and test the setup:
# Create binder device
$ sudo rsb_device binder
# Verify device creation
$ ls -la /dev/binderfs/binder
# Test with a simple example
$ git clone https://github.com/hiking90/rsbinder.git
$ cd rsbinder/example-hello
# Start service manager in one terminal
$ rsb_hub
# In another terminal, run the example
$ cargo run --bin hello_service &
$ cargo run --bin hello_client
Persistent Configuration
To automatically load binder modules on boot:
# Create module loading configuration
$ echo "binder_linux" | sudo tee /etc/modules-load.d/binder.conf
# Set module parameters
$ echo "options binder_linux devices=binder,hwbinder,vndbinder" | sudo tee /etc/modprobe.d/binder.conf
Troubleshooting
If you encounter issues:
# Check kernel messages for binder-related errors
$ dmesg | grep -i binder
# Verify zen kernel is running
$ uname -r | grep zen
# Check if modules loaded successfully
$ sudo modprobe -v binder_linux
