Re: [9fans] Nemo's Opus

[Winston Kodogo]

To add to the previous comments, I'm a huge fan of Nemo's “Introduction to
Operating Systems Abstractions”:

https://lsub.org/who/nemo/9.intro.pdf

It's just a brilliant guide to finding your way around the system, and
doing some programming in it, especially if you're not a kernel-head and
talk of "ring 0" makes your brain hurt.

Not that my being a huge fan of anything of anything is in general a
recommendation, but in this case I'm right.

Does plan9 on the rpi run armv8? I thought it was armv7 even on the rpi3.

I understood that he wanted to start with a distribution with amd64
support, not to start running it on amd64. Most, if not all, rpi
sources has been integrated into bell labs' distribution. It's not
clear to me if he wants the distribution with better amd64 support or
the most used/developed/supported with amd64 support (from the
question looks more the later).

I predict suffering.

Benjamin:  I wouldn't get too hung up on amd64 specifically.  Labs,
9atom, and 9front should all work fine out of the box, and by the time
you're using the system enough to be interested in accessing larger
memory, you'll have a clear idea of which direction you want to go.

I'm making an assumption there that memory support is what motivates
your request for amd64 -- is there another reason you have in mind?  For
most cases, there isn't a tremendous difference a user would notice
otherwise.  i386 and amd64 live in harmony here.

I would bet that the best distribution to start working with out of
the box is the rpi image by Richard Miller. It's bell labs' based,
afaik, but probably the most active fork is 9front (or maybe there is
no fork).

[9fans] 9front on raspberry pi

[Chris McGee]

Hi All,

I have an experimental (read unstable, may void the warranty) merge of Richard 
Miller's kernel for raspberry Pi into 9front. It is capable of running Go 
programs and sdk.

The code is here as a drop in replacement for existing /sys/src/9/bcm:
https://github.com/sirnewton01/rpi-9front

Also, there is a release with an sdcard image there from the last 9front 
release. Tested briefly with a Pi B+ and Pi 2 B. In theory it could work with 
other models such as zero.

If you find problems either with the code or in testing comments are welcome 
either as response to this email or github issue. Pull requests are welcome.

Cheers,
Chris

Hi!

   Since a similar line of conversation came up recently, I thought I'd ask...

   Maybe this was just my perception, but I remember that years ago, there 
seemed to be a pretty strong aversion to forking the official distribution from 
Bell Labs.  These days I'm not certain where the majority of the activity 
occurs, and which of the forks is the most "official", or at least 
"mainstream"...


   What would be the best place to start in, looking for the most 
current/widely-used distribution with amd64 support?  9front?  9atom?  Other?


As always, many thanks!
