How not to break PREEMPT_RT by Sebastian Siewior, Linutronix at LPC 2022 in Dublin 

The PREEMPT_RT patch set has only a handful patches left until it can be enabled on the X86  Architecture at the time of writing. The work has not finished once the patches are fully merged. A new issue is how to not break parts of PREEMPT_RT in future development by making assumption which are not compatible or lead to large latencies. Another problem is how to address limitations on PREEMPT_RT like the big softirq/ bottom halves lock which can lead to high latencies.
