Linux doesn’t target the xtensa nor does it have a proper mmu so this is emulating a risc-v. It is still very much in the novelty “hack” realm.

There does seem to be a Xtensa Linux port, but you need a Xtensa chip that has some more features than the ESP32 does. http://wiki.linux-xtensa.org/index.php/Supported_Processors

Ah, then that's different, because I've run Linux under an Armv5 device with 32+16mb of RAM with zram just fine.
