Support for vTaskList and vTaskGetRunTimeStats

[trlafleur]

Will these FreeRTOS function be exposed in a future release of the Arduino code build?

vTaskList
vTaskGetRunTimeStats

You could compile the libraries with the needed options yourself:
http://esp-idf.readthedocs.io/en/latest/api-reference/system/freertos.html#_CPPv29vTaskListPc
#1142

I've built the blink example with esp-idf and the appropriate options in sdkconfig (via make menuconfig/Component config/FreeRTOS) and the FreeRTOS options are built. But not entirely clear to me how to merge my build into the arduino-esp32 directories. Do I need to take the entire batch of archives from my project build and just overlay the archives in ../arduino-esp32/tools/sdk/lib? I tried just overlaying the libfreertos.a and get a couple of undefined symbols (_thread_local_start and _thread_local_end); not clear which archive they are in. Are there any other changes or considerations needed?

[lbernstone]

Follow the directions in issue 1142. You must have your esp-idf repo synched to the same point that arduino-esp32 was last built at (currently f586f5e) or you may have mismatched symbols/functions. It should then just be a matter of copying the libfreertos.a archive to the lib directory. I haven't ever done this for libfreertos.a, but have replaced libesp32 and liblwip.a before.

[trlafleur]

It would be nice if it just worked without having to rebuild it all when a new release is out...

[lbernstone]

arduino-esp32 is set up for simplicity. If you are micromanaging your tasks, you should probably be using esp-idf or arduino as a component. Please close the issue if this is now working for you.

I finally got this working, there was one little trick that took a while for me to figure out, the arduino-esp32/tools/sdk/include/config/sdkconfig.h needs to be updated with the appropriate defines in the Blink/build/include/sdkconfig.h which is generated by make menuconfig. I did a diff on the files between my esp-idf Blink example build and the arduino-esp32 version and merged the appropriate debug settings:
#define CONFIG_FREERTOS_USE_TRACE_FACILITY 1
#define CONFIG_FREERTOS_USE_STATS_FORMATTING_FUNCTIONS 1
#define CONFIG_FREERTOS_GENERATE_RUN_TIME_STATS 1
#define CONFIG_FREERTOS_RUN_TIME_STATS_USING_ESP_TIMER 1
Only the Blink/build/freertos/libfreertos.a needed to be copied to arduino-esp32/tools/sdk/lib.
vTaskList and vTaskRunTimeStats work now.

As noted in last comment, it can be made to work. It appears that in the "ESP-IDF Release v3.0, release notes" we see that Runtime stats are available in the base code. --> "FreeRTOS Runtime statistics support (configurable via menuconfig)"....

So the work is done, we just need to have a way to enable in the Arduino port with out a re-compile or modification of the base code...

[themindfactory]

maybe someone can post the libfreertos.a I am unable to create it...

[themindfactory]

Would be awesome for these to be added, more and more people spawning tasks and this info would be nice to have access to.

[trlafleur]

is it possible to get these function exposed so one can use them under the Arduino platform...

Thanks

[lbernstone]

Will it make more sense to you if I just say no?

[trlafleur]

No, it's a very useful features of freertos when developing code. Ive been using freertos for 8 years now. Lots of experience with it... It's a great tool

@trlafleur while it is a useful tool for some it isn't highly useful for the majority of Arduino users. I'd suggest shift to Arduino as an IDF component instead.

[trlafleur]

Enabling the features in the Arduino ide will not effect most users, but will allow those who need it to have it..... I have many students in my classes, and would love to access it with out having to move to the IDF.... ~~ _/) ~~~~ _/) ~~~~ _/) ~~~~ _/) ~~ Tom Lafleur

Profiling features require memory and cpu cycles. Most people are not willing to pay that penalty, essentially having the device in a debug mode all the time. What I can offer, is that @atanisoft has made it significantly easier to compile your own libraries (or compile from scratch every time), by making a simplified method to compile arduino as an esp-idf component in platform.io. Watch that page in the next couple months for instructions on how to do this.

[trlafleur]

Thanks, that would be great to find an easy way to build the code... PS: ESP32 processor have a lot of CPU power, adding any debug code in most cases make very little performance hit... ~~ _/) ~~~~ _/) ~~~~ _/) ~~~~ _/) ~~ Tom Lafleur

[trlafleur]

as a minimum would consider just adding vTaskList to the Arduino release, minimal code increase...
and it's no more complicated to use as any other FreeRTOS function.
