Join the ELISA community on Tuesday, October 11 at 8-9 am PT for the next ELISA Monthly Seminar. Sebastian Siewior from Linutronix will present “PREEMPT_RT – how not to break it.”
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.
