Support for vTaskList() in Arduino core so we can monitor task status

Related area

FreeRTOS

Hardware specification

All esp32 devices

Is your feature request related to a problem?

No

Describe the solution you'd like

Current when you use vTaskList() FreeRTOS API and try to compile, you get this error: "undefined reference".
The runtime stats must be enabled in FreeRTOS so you can use this API. I think the solution is to enable runtime stats by default.

Describe alternatives you've considered

I have checked existing list of Feature requests and the Contribution Guide

We need to check if this will cause any performance/memory degradation first.

[qnxsgwy]

If can view the cpu usage, is very useful for debugging, hope to support this function.
But performance degradation also needs attention，hopefully as an option that can be on/off at compile time.

Well, I'm no stranger to squeezing performance out of the ESP32 and I use it by default on my projects.
48kHz stereo realtime MP3 encoder: https://www.esp32.com/viewtopic.php?f=2&t=9186
Using it to gauge performance really didn't notice any issues at all. I think there is certainly more benefit than potential issues. Also Arduino being something that is also used as a learning tool, it would be extremely beneficial to allow users to see tasks usage and CPU affinity. Happy to add an example if it's added.
This applies to vTaskList & vTaskGetRunTimeStats().
This keeps coming up here as a feature request by different people, it's probably not going away...

I too would very much appreciate this support in the Arudino variant... just hit this omission myself!

[zekageri]

+1

[szerwi]

+1, I would also need that feature in my project

[everslick]

me 2

[yekomS]

also need this feature and vTaskGetRunTimeStats() :-)

[marnov999]

so any new info on this? I would need it too, or maybe some way to recompile the lib ourself with the feature enabled?

[davepl]

I wound up making my own idle threads that whack the watchdog and track whatever idle cycles they can burn, and that gives me overall CPU, but not per-task… From: marnov999 ***@***.***> Sent: Saturday, December 31, 2022 7:13 AM To: espressif/arduino-esp32 ***@***.***> Cc: David W Plummer ***@***.***>; Comment ***@***.***> Subject: Re: [espressif/arduino-esp32] Support for vTaskList() in Arduino core so we can monitor task status (Issue #7179) so any new info on this?

Yeah defo missing this too, just started using RTOS tasks, and need a way to list and monitor them. This looks like just the ticket.

[synologic]

All, this has been discussed all over the internet for quite a while now, we should get it :)

[VojtechBartoska]

Hello all, changing this to 3.1.0 milestone, we are starting investigating if this is doable and let you know.

@lucasssvaz will do the research and share the updates later here.

[lucasssvaz]

We'll first need to implement some way to easily reconfigure and recompile the libs for the users. Currently working on that. espressif/esp32-arduino-lib-builder#158

[me-no-dev]

Will something like that work? #10515 (comment)

[hitecSmartHome]

It would be the best if it would return or populate an array or json instead of printing it out. That way we could actually do something with the results

[me-no-dev]

@hitecSmartHome that is up to you to implement. You can use the code in the PR as starting point. Array is already used there and that is what is printed.

[hitecSmartHome]

I see.
