Just Curious, As for the title.
I found an old article: https://docs.rtems.org/releases/rtemsdocs-4.6.0pre5/share/rtems/html/supplements/m68k/m68k00062.html, it said rtems's interrupt latency on MC68020 is The maximum period with interrupts disabled + 9 microseconds on 20Mhz. I see zephyr provided a "Zero-Latency interrupt" facility to do with near bare metal performance interrupt handler, and a talk is about using Zero-Latency Interrupts feature to make a ESC with ZephyRTOS. Is rtems good enough to do the same thing?
