[9fans] build iso's plan9 for amd64, atom, arm, powerpc

[Francesco Cardi]

Hello I have read many useful information on the net but I have not
found specific details to create the image of plan 9 for each
platform, I saw the patch applied by 9legacy but the notes are not
very detailed, who can give me the documentation for create iso differ
according to the architecture of use, I want to create an iso for
amd64, one per atom, one for arm and finally one for powerpc, I think
it's also nice that anyone can download from the internet without
trying to infinity, let me know.

greetings

i currently have an iso image with amd64, arm, and 386 binaries. it's
not tested because i am waiting on a sata cd drive. however, it's not
clear to me that the binaries are anything but dead weight in the cd
because if you can run amd64, you should be able to install as a 386
machine and compile /sys/src yourself. if you've got an arm, then
i am not sure how it makes sense to boot from an iso image. how
does that work. in any event, you can install on a 386 and move onto
arm from there. it's probablly not ideal, but it should work.

i'm wondering if the install media should contain nothing but the
source, a bootstrap loader, a kernel and just enough binaries to
be able to compile all the source for whatever arches you're interested
in.

I recently put together just such a thing for arm. This set of binaries
is enough to build everything else:

arm - sys sys
init - sys sys
bin - sys sys
mk - sys sys
rm - sys sys
echo - sys sys
5c - sys sys
5l - sys sys
5a - sys sys
lex - sys sys
yacc - sys sys
ar - sys sys
test - sys sys
rc - sys sys
mntgen - sys sys
bind - sys sys
ls - sys sys
disk - sys sys
fdisk - sys sys
prep - sys sys
grep - sys sys
read - sys sys
ndb - sys sys
cs - sys sys
dns - sys sys
ip - sys sys
ipconfig - sys sys
aux - sys sys
timesync - sys sys
chmod - sys sys
cat - sys sys
ps - sys sys
awk - sys sys
sed - sys sys
date - sys sys
awd - sys sys
cp - sys sys
tr - sys sys
pcc - sys sys
cpp - sys sys
mv - sys sys

I have one that I'm not using, would you like me to mail it to you?

I think the most practical thing is to create an iso based on the
specific architecture you have, you have to give me the link, the
messages I have written does not give me complete information but they
are only concepts, I need documntazione I want to build a iso, do not
want to create a combo iso for various things

[John Floren]

What I think people are trying to say is that this doesn't really make
a lot of sense. The AMD64 system doesn't have any installer work done
for it at all--I think it's not far off, but to the best of my
knowledge nobody has built a CDROM that boots the 64-bit kernel and
gives you the installer from there (Erik, have you done this yet?).
I've never even SEEN an ARM system with a CD-ROM, and it's uncertain
if a given ARM system's bootloader will support booting from a USB
CD-ROM drive; it's just not how OSes are installed on ARM!

operating systems such as the family has bsd iso images for
architecture selection, plan 9 does not have all the iso images
because it has so many volunteers, but if it is possible to compile
the kernel for the amd64 architecture is also can create the iso with
the new kernel loaded, the same thing is to arm, not a problem if the
problem is not a CD i do not have an iso for the architecture that i
use, you have the link to the documentation?

no, i don't see the point. it's a multi platform thing and there is nothing
lost in installing or installing from the 32-bit binaries, even if you run
a 64-bit kernel.

it's a multi platform thing

by this i mean, a big plus for plan 9 is the ability to seemlessly
deal with many architectures.

ah ok
so I do not need to load the kernel for specific architecture? is
already supported native?

I think some of the acorn machines had CDROM drives. They can't boot from them though.

right and so it's like I said, I read in the documentation that you
have loaded the kernel-specific architecture along, I want to load the
kernel and then create an iso with that kernel, the same thing has
been made with nix-os is to plan 9 amd64.
There is documentation to create the iso?

[Matthew Veety]

Here's how to make a 9front iso. I would guess
that building a bell labs dist is similar.

Not that similar.

I did boot nix with the new boot loaders from a CD image, so that part
worked. Erik is using a different boot loader I think, but it probably works too
(it boot in 32 bit mode after all...).

After booting the kernel, as Erik says, it should not be too hard.

For ARM Richard Miller is doing an excellent work with his prerrolled
Plan 9 images for the raspberry pi, so that is probably the way to go.

Actually 16 bit mode...

the 9atom cd boots to 32-bits, but the 64-bit kernels are right there.
it should be no problem if you have a 64-bit capable machine to boot
into a 64-bit kernel after compiling /sys/src.

the reason i don't boot directly to 64-bits is because that's probablly
a lot of busy work without a lot of benefit. also all 64-bit intel run
32-bit kernels, but not vice-versa.

yes, iplpxe which really is a slight reworking of cinap's work.
while it starts in 16-bit mode, it does all of its work in 32-bit
segmented mode. (that is, paging is off.)

it has the ability to boot 64-bit, pae or po32b. (plain old 32-bit.)
the main requirement to boot 64-bit it to accept S_MAGIC.

(i am still using ye olde 9load-e820 on the cd. this is laziness.
it can also boot a 64-bit kernel, though. but it does not have
boot menus.)

9atom2 includes rpi. install on a 32- or 64-bit intel, and
cd /sys/src;
objtype=arm mk install

thanks, one should be coming this week.
