This isar layer allows to build debian based preempt_rt evaluation images for the starfive visionfive2 and the raspberry pi 4.
The images include:
- A custom kernel with the PREEMPT_RT patch applied
- Some realtime tuning
- Realtime evaluation tools
- OSADL patches and tools needed to integrate it in the OSADL QA farm
Find the latency plots generated in the OSADL QA farm here: https://www.osadl.org/Latency-plot-of-system-in-rack-3-slot.qa-latencyplot-r3s2.0.html?shadow=1
A container engine like podman or docker has to be installed.
Run kas-container to build the desired image:
./kas-container build kas/<target>.yml
Supported targets:
- raspberry-pi4-kernel-5.15-rt
- raspberry-pi4-kernel-6.6-rt
- starfive-visionfive2-1.2a-kernel-6.6-rt
- starfive-visionfive2-1.3b-kernel-5.15-rt
- starfive-visionfive2-1.3b-kernel-6.6-rt
