[PATCH] target/xtensa: import core lx106
Posted by Simon Safar via 2 years ago
This is the core used in e.g. ESP8266 chips. Importing them
using import_core.sh, with the required files sourced from

https://github.com/espressif/xtensa-overlays

core-lx106.c was generated by the script; the only change is removing
the reference to core-matmap.h which doesn't seem to be available.

An update to target/xtensa/cores.list is needed for this core to be built
in qemu-6.2+. Please keep that file alphabetically sorted.
With that addressed:

I'm curious how is it supposed to be used?

sounds great, thank you for the review!!! Will send out v2 soon.

> I'm curious how is it supposed to be used?

It's for a (future...) Lisp compiler! Somewhat in the style of MicroPython; the idea is to make code editable on the fly, without reflashing (... or restarting, even). Given how it's one person's side project (mine), it's a lot closer to a (not-even-self-hosting) lispy-syntax lx106 assembler (... written in Common Lisp) at this point though.

Specifically, qemu is being used for testing code generation; within test cases, we generate an object file, link it up into an ELF image, launch it under qemu & check the output. Current top achievement: a loop that iterates 10 times and quits successfully, by using the emulated syscall interface. Even so, having actual test cases for this (& occasionally attaching gdb to them) is really useful.

(Admittedly, I can't really think of a lot of other use cases; probably everyone else is just using the official C toolchain?)

Interesting. Do you use libisa or do you do instruction encoding on your own?

It's my own; it's generating opcodes from the tree of tables in the Xtensa reference. A large part of the actual code looks a lot like those tables themselves; there are still some missing parts for some (e.g. overriding some defaults on which instruction is taking what kinds of parameters), which I'm just filling in on the go. It's fairly hacky, but it might fit together well with the eventual purpose of maybe running some of this in that 40k RAM onboard & keeping it all Lisp.

(I'll put it up somewhere eventually once it's not a complete mess & starts doing something interesting! assuming this ever happens, of course.)

I see. I once did something like that for QEMU TCG:
https://github.com/OSLL/qemu-xtensa/commit/53604287d6fdad1ce9659135a8ecbb569be90380

40k of RAM is a reasonable concern (: I would guess though that libisa + xtensa
core description are purely code and constant data, and as such they may be
put into FLASH and not consume any RAM.
