Comparing ISR Handling in FreeRTOS, ChibiOS, and CooCox CoOS for ARM Cortex-M Projects?

Hey guys, I’m evaluating open-source RTOS options for an ARM Cortex-M project. While FreeRTOS, ChibiOS, and CooCox CoOS seem to offer similar features, I’m curious about real-world experiences.

Specifically, how do these RTOS handle ISR interactions e.g., ChibiOS’s “`chSysLockFromIsr“` vs. CooCox CoOS’s preemptable service request queue?

Any insights on these or other open-source RTOS options for ARM Cortex-M would be greatly appreciated!
