huh.  I guess there was a recent machine with sata and GbE and a
decent cpu/ram (tegra 2/1GB).  $200.  I'm still a little hesitant
about Nvidia, but to avoid further damaging relations with processor
designers I'll defer to Torvalds' statement on the matter from
Thursday in Finland.

I have a tegra 2 and it's completely undocumented and only comes with
binary display drivers.

Speaking of tegra, what the hell happened with linux4tegra?  It was
announced, delayed, released, and then pulled?  Is that correct?

linux4tegra exists. I can run quake 3 and drawterm on my ac100,
connected to big TVs via HDMI :D
doesn't help plan9 though.

Thank you a lot.  There are some nice devices I've never heard
about before, including the Cubox.

Another neat comparison of 44 tiny devices:

I wonder which one will run Plan9 without much of a hassle. Have to wait somebody to crack RaspberryPi.

Hi,

I am waiting for my RaspPi to start some cracking, but meanwhile you can
have a look at http://kernelnomicon.org/ which is illustrating the
progress for RPi to boot FreeBSD. It provides useful bunch of info about
booting process that RPi uses - can be a very good starting point.

No mention of the $16 Teensy?  http://www.pjrc.com/

...or the Arduino?

Re: [9fans] apparently nice summary of small linux pcs

[Jack Norton]

I'd like to share with everyone that I've just purchased one of these:
https://www.olimex.com/dev/imx233-olinuxino-micro.html

I liked how they have all their schematics and layouts are on github and
that the freescale chip would be a bit friendlier than something from
nvidia or broadcom (not to mention you can actually purchase low qty of
this chip if you wanted to).  There is a larger version as well (go to
Olimex's main site and navigate to the product family 'olinuxino').

I've always had good experiences with Olimex stuff.  I am really glad to
see them still in operation.

It's an 8-bit, what are you going to put on it, CP-M? ;) Granted, some
of the old 8-bit OSs can be quite nice. I really like the one in the
Atari 800, it has a really unified device interface, but it's no Plan 9.

Actually I've toyed with the idea of a "Plan 9 from 8-bit space". It
would be a fun challenge, I think, and I'd be interested to find
exactly what compromises would be needed. It may even be less of a
challenge than writing drivers for the crap peripherals ARM SOCs always
seem to be burdened with, but what could you do with it when it was
done?

>
> ...or the Arduino?

An overpriced and underpowered member of a class of devices that are
far short of running Plan 9 in the first place. And why on Earth is it
programmed in C++?

This is obviously some strange usage of the

you don't want plan 9 on an 8 bit machine.

Re: [9fans] apparently nice summary of small linux pcs

More to the point, you don't want any OS on an 8 bit machine.

A small driver library, maybe.  But really, 8 bit machines today are
just for fun little micro-control projects and you really don't want
an OS in the way.
The first thing I did to make an arduino useful was reclaim the timer
thread that the arduino "OS" steals from you...

You do on the wireless motes, because you have several networks and a file
system.
There isn't a "user mode" of course, but there are applications. ours was a
noise
monitoring system to some international noise-monitoring standard.

it's an opinion that 8 bits don't have mmus?
that's taking relativism to a whole new level.

Which, of course, doesn't say anything about wanting styx/9p
on such a machine. Every time we get to this point in this
(recurring) conversation, I'm compelled to make sure everyone
has seen the excellent Styx on a Brick paper, describing work
to export the sensors and motors connected to a Lego
Mindstorm controller over styx.

What would be possible is to build a general purpose
building block. Something like this:
- provide a tiny thread library
- provide 9p over USB|serial|UDP
- implement a simple 9p server framework & export a server
  side interface where one can plug in sensor/actuator
  specific routines and specify the FS layout via a string.
- implement a namespace convention for discovering
  capabilities (for example a "help/" dir)
- it should be implementable as a verilog block some day!
  may be not but imagining that keeps the design simple.

Actually it doesn't have to be 9p. It can be something
simpler.

what i was trying to say before, is that there is already
some research in the area.  it doesn't have to be proven possible.

I have read the styx papers. The concept is of course not new.
What I am talking about is packaging up as a reusable
component.  Specifically
- server side api
- ability to discover capabilities. no new client side drivers
  for each new device.

As for "simpler than 9p" I had a different thing in mind from
what is in various iwp9 papers. Not worth talking about in the
abstract.
