edit to rephrase my question more concretely:
As far as I understand, Balena does provide a CONFIG_PREEMPT_VOLUNTARY kernel with CONFIG_HZ_1000 tick.
Baleno does not provide a CONFIG_PREEMPT kernel with CONFIG_HZ_1000 tick (like Ubuntu’s low-latency kernel). And nor does it provide a CONFIG_PREEMPT_RT kernel.
Is that correct? And if so, is there anything on the roadmap that aims to deliver something similar to Ubuntu’s low-latency configuration?
