The colcon-acceleration ROS 2 package provides an extension for colcon-core (a series of ROS 2 build tools) to include Hardware Acceleration capabilities.

The linux verb helps configure the Linux kernel in the raw SD card image produced by the firmware. E.g. colcon acceleration linux vanilla will produce a Linux vanilla kernel, whereas colcon acceleration linux preempt_rt will instead use a pre-built kernel and kernel modules for improved determinism (fully preemptible kernel). For more details, check out the ROS 2 Hardware Acceleration Working Group (HAWG) community repository or the introductory paper.
