that's what i think now. project maybe done, maybe produced but...
Here are a few meaningless numbers:
- a 1.8GHz amd64 processor is about 6 times faster than a 900MHz
Loongson 2F doing md5 crypto.
- the same processor is only 3 times faster doing Blowfish crypto.

AFAIK the JIT is Qemu's; the extra instructions just help the translation from x86 -
tiny code generator bytecode (similar to LLVM) - Loongson. I doubt there's much
magic to it other than minimizing host CPU instructions but... I'm talking out of my ass.
On the other hand you're right to

well my question wasn't about running x86 code under emulation on

The answer is it depends.
It takes a long time to build certain

It has been available for ages, and well-supported by free software as
well; and I am not only speaking about loongson-based systems.

Argg, was using the wrong names.
Notebook is called Yeeloong, mini-PC Fuloong. Processor Loongson.

Note that all this is because of PMON bugs, we did our best to
circumvent the bugs, but this is the best we can do.
No, we can do better. The real pie-in-the-sky fix is to do what had been
done on hp300 30 years ago: make the bootloader actually be a kernel
without userland, scheduling and

Nope, you are confusing things.

where are Loongson 3 based computers available?
In dreamland only.
how can loongson 3 be (roughly) compared to x86 CPUs in performance?
It's slower. A hell lot slower.
3A systems are running at around 1GHz. The x86 code translation stuff
was benchmark-only and, to the best of my knowledge,

Thanks for the great work and the informative posts. I'm saving the info for
future reference. Especially the history on the Loongson line is great to
know.

I haven't been able to figure out how to setup an entry in pmon's boot.cfg

the OpenBSD boot prompt works correctly.
I've tried all sorts of stuff with the args parameter, no joy. Can anyone
clue me in? Thank you.

Thanks, Otto. I have no complaints. I really appreciate the work everybody
did on this. Just wanted to make sure I wasn't missing something obvious.
I figured it would be nice to have a menu selection for booting single user
