NetBSD 6.1.5 is running on my SGI Indy, yay!

Hi guys!,

Just wanted to say that my SGI Indy is now running NetBSD, of course,
version 6.1.5. Took a bit of figuring out to get it installed via the
network and setup to autoboot, but I got it done in the end. Still
find it quite amazing that I can run a new operative system on my old
indigo colored MIPS machine. Once I had sysinst up and running it was
easy, good old familiar sysinst.

I had some issues when reading the INSTALL.txt, well they were good
issues since I got to learn something about dhcpd, tcpdump, the SGI's
Boot PROM and got NetBSD installed and running in return.

Anyway, I attached the dmesg.boot if anyone is interested.

Take care guys!,
and thanks for all the ports.

SGI Fuel

Hi,

I got a SGI Fuel and I would like to install something useful on it :-)

I read that you can install OpenBSD on such computers. 

On the port-sgimpis- page these machine isn't listet... I know... But is
it possible to run NetBSD on it (like Sun Blade 2000; these machines
aren't supported too as described on port-sparc64- page but is running
NetBSD)

It would be great to run NetBSD on it :-)

Greetings,
Helge

Can't boot SGI O2

Hi!

My SGI O2 can't boot.  It hangs up in pmap.c:pmap_bootstrap().

arch/mips/mips/locore.S
  arch/sgimips/sgimips/mach_init()
    arch/mips/mips/pmap_bootstrap()
      kern/vfs_bio.c:buf_memcalc()
        if (bufpages != 0) {
          :
        } else {
          :
          mapsz = vm_map_max(buf_map) - vm_map_min(buf_map); 
        }
  kern/init_main.c:main()
    :
    kern/vfs_bio.c:bufinit()
      if (bufmem_valimit != 0) {
        :
        buf_map = uvm_km_suballoc(...)
        :
      } else
        buf_map = kernel_map;

And valiable 'bufpages' is maybe 0 on all mips ports.

IP32 debugging kernel intr handler (crime/mace)

Hi,

I'm digging into 47640 on sgimips (SGI O2 IP32) on netbsd-current
(6.99.17).

http://gnats.NetBSD.org/cgi-bin/query-pr-single.pl?number=47640

Background
-----------------
I'm basically starting out on kernel tinkering.

As explained in the gnats this SGI IP32 will hard lock at random point.
Otherwise it operates very nice and quickly. That was 6.0.1, same deal
on current. 
Also 47639, a random keyboard flash co-incides with a interrupt, may be
related.

What I want to do, but don't know if i can:
- get a debugger triggered at the right point, which means finding the
  right spot
- adding more debug around some other bits of kernel code, but not so to
  saturate the console
- breaking the kernel (linux magic sysreq style) and just getting it to
  dump it's stack at a keypress

The hunch was a glitch in the interrupt handling, so I've added
aprint_debug() liberally throughout dev/crime.c and mace/mace.c, as seen
in
https://gist.github.com/rooprob/5191131

sgi O2 VICE and Nintendo64


I had a memory burp: O2 VICE and Nintendo64 ; someone asking about N64 kernel; 
Brain righted itself n64 (32/64bit ABI) not N64 (Nintendo), or n32 or o32 subset.

Anyway, I randomly googled, refreshing my world view that the O2 is scattered
amongst the different projects;
- The hardware acceleration in VICE (derivative found in Nintendo64) was in
  Linux 2.5.x (http://www.linux-mips.org/~glaurung/), 
- Macallans excellent O2 2D acceleration work (didn't use VICE IIRC) X11 work
  in NetBSD (http://my.opera.com/Macallan/blog/2009/04/01/xorg-on-o2) 
  (Was this only XFree, or was carried over to Xorg?)
- OpenBSD's support for the O2 system generally seems more featureful and
  stable.
- Finally, back to IRIX, the guys at Nekochan have updated Firefox to 3
  (http://forums.nekochan.net/viewtopic.php?f=15&t=16727403) for IRIX and report
  faster, more stable behaviour than ff2.x (haven't tried it). 

But what's happening over in Nintendo world, and we find some nice research
into RSP from 2012/2013,

http://forum.pj64-emu.com/showthread.php?t=3398
https://github.com/cxd4/rcp/tree/master/rsp

Is O2 VICE and the Nintendo64 near enough this research useful?

Just posting if this is interesting.
