[9fans] 9atom.iso

[erik quanstrom]

there's a new one at ftp://ftp.quanstro.net/other/9atom.iso.gz
unfortunately it won't solve baux80's problem, i don't think.
i haven't gotten together a reasonable debugging version of
9load yet.  i'm still working on that.

the new iso mostly contains new device ids but it also has a a
few things like a workaround^w i mean support for ata puis.

I'll give it a try and let you know :)

So, I'll install plan9 via qemu and try to work around (if your new iso
dosn't boot) bootstrap.

thank you again :)

exact. Doesn't boot anymore.

but on qemu plan9 installs well :)

Now, I run it on my personal laptop. Should I install cpu server and auth or
use it as a simple terminal. What's the best practice for a personal machine ?

thanks

Boots fine from the CD and installs on a Shuttle X27. When booting
from the hard disk, I get a lot of

    ide: caught missed irq

and no working system. It hangs somewhere after

    version... time...

it's not hung, it's just really really sloooow.  caught missed
irq means that it's trying to forge ahead even though
the ide irq has been somehow misrouted.  my ide driver
tries to do its best in these cases, since this is a very common
problem.

 do you have a recognized southbridge?  there should
be a dev file /dev/mpirq (or nompirq if mp irqs are off)
that describes the mp table.  sometimes you'll see that there
are two mappings from bus irq to processor irq that are
the same except for the i/o apic output pin.  without the
routing tables, you don't know which one is correct.

it would be nice to be able to override irqs in plan9.ini.

I don't see neither /dev/mpirq nor /dev/nompirq.

you're correct.  the quickest fix would be to download
the atom sources and recompile with "nomp" in the link
section.  i will correct the cd.  sorry.

have you tried with "*nomp=1"?

Re: [9fans] 9atom.iso

I have a *nomp=1 in plan9.ini.

have your tried dma on?

my installation has the same problem, but once it starts dma on
everything works fine.
It is annoying if you only enable dma through cpurc or termrc because
untill it runs them everything is slow. good erik's sd stuff allows
you to run dma right at the begining.

i'm glad that's unsightly hack is working for you.
clearly we're doing some pio naughty.  this should
get fixed.

if anyone with this problem can bring the offending
equipment in, i'll try to take a quick look or, if
you're willing, we can try remote debugging.

Adding *sdE0dma=on fixed the problem.

just to be clear, the plan9.ini syntax is
*sdC0dma=on
replace C0 with the drive id in question.

crude but sometimes effiective.

i missed this in my original reply.  i would guess that
turning off mp interrupts will do the trick for you.
the mp table must be confusing things.
