thread id's of the idle and the timer thread #449

Closed joabeck closed 5 years ago

joabeck commented 5 years ago

Dears Sirs, i want to know the free stack space of all the threads in my software (runtime not only in the debugger). For the user threads i can get the stack space with the function osThreadGetStackSpace. This function needs the thread id as parameter. How can i get the thread id's of the idle and the timer threads?

Thank you for your support. Best regards Joachim Beck

Hi Joachim,

We currently don't have a public API to access these internals. But you can use the pointers from osRtxInfo (the global RTOS control block). The idle thread is linked by osRtxInfo.thread.idle and the timer thread by osRtxInfo.timer.thread.

Does this solve your requirements?

Cheers, Jonatan

Hi Jonathan, i can live with this, but i think this is not portable, if one wants to use another CMSIS RTOS2. Thank you Cheers Joachim

Hi Joachim,

Yes, of course this is not portable. In fact having timer and idle threads is some kind of implementation specific, anyway. Hence I don't see how one could ever make this really portable.

We expect portable software components (e.g. communication stacks) relying on a limited subset of RTOS primitives not having a dependency like this.

Cheers, Jonatan
