FPU in Interrupt

[MattiaBerton]

Hello,
I'm using an ESP32-S3. I found that there is not the option "CONFIG_FREERTOS_FPU_IN_ISR", while it is present if I set IDF-TARGET=ESP32. Is there any reason for which there is not such an option? Is there any way to enable?
Thanks!

Seems that that option was last touched in 2022; I don't think the ESP32-S3 was on the map back then so I think it just didn't get included. The ESP32 and ESP32S3 FPUs are pretty much the same, so you may be able to hack support in by simply enabling the option. For that, edit esp-idf/components/freertos/Kconfig , find FREERTOS_FPU_IN_ISR, and change the 'depends' line under it to 'depends on IDF_TARGET_ESP32 || IDF_TARGET_ESP32S3'

I'll file a ticket here for someone to look at this properly. If you get some results (either positive or negative) with the above change, please post it here.

I applied your changes, and now it works even with ESP32-S3.

Thanks, we'll probably change this in some upcoming version of ESP-IDF as well then.
