ESP32-S3 documentation

With ESP32-S3 supporting vector instructions (this sounds cool), is there any chance of getting official ISA/ASM and ROM documentation so we can actually utilize these new capabilities?

Yes, the extended instructions are scheduled to be documented in a TRM chapter.

So, you guys can now release official documentation for the full Xtensa LX7 ISA? That would be wonderful!!

Also, documentation on what is in the ROM, and Wifi, so we don't have to use RTOS/LWip if we choose not to!!

No, we cannot. Only the instructions we added ourselves (the vector instructions) are our property so we can release docs for those at will.

I don't think the S3 will have a different policy there than the existing chips.
