If I run a Linux process on a certain processor # 0 and on another processor task of Xenomai # 1, will the Xenomai tasks never interrupt the execution of the Linux task? ^ permalink raw reply [flat|nested] 4+ messages in thread

I think so, ftrace can show that on different cores, they are running in parallel. but if u put all the 4 rt-threads onto one core, they cannot run in parallel. assume all are SCHED_FIFO, higher priority thread will preempt the lowers. > > Il mer 3 mar 2021, 13:03 Fino Meng <fino.meng@linux.intel.com> ha scritto: > > > O Wed, Mar 03, 2021 at 11:24:00AM +0100, Leandro Bucci via Xenomai wrote: > > > hello, I would like confirmation to this question.
