SMP support for Daystar 604e 200MHz dual-processor card

SMP support for Daystar 604e 200MHz dual-processor card

[David D. Kilzer]

Hi,

Is anyone running LinuxPPC with a Daystart 604e 200MHz dual-processor card?

I've compiled 2.2.12 from CVS source, and the kernel oops with some sort of
MMU fault.  (I can print out the exact error if necessary.)

I've also compiled 2.3.15 from CVS source, but it doesn't even get past the
initial screen that ends with "booting...".

Both kernels had SMP support compiled in.  I have not tried compiling a
kernel without SMP.

I'm using BootX 1.1.3 with only my root partition (/dev/sdb9) defined.

I have a working MkLinux installation (using glibc 2.0) with the
pmac-utils-1.1.1-1a.ppc.rpm installed (rebuilt from source) that boots fine.

Any ideas?  I haven't tried adding debug code or perusing the source, yet,
but I expected this configuration to work out-of-the-box since Daystar and
Apple SMP cards are supposed to be essentially the same.

Thanks!

Dave

I am!  :)

You can pick up my kernel from ftp://borg.mit.edu/pub/linux/ppc/kernels/

The multiprocessor one is 2.2.10, and the uniprocessor is 2.2.5 (I know, I 
know... I should update)

[Sriranga Veeraraghavan]

Hi,

I think that I have the same card, the nPower 400 (2 604e 200's).

So far I have only been able to boot two SMP kernels on it in R4, my
own 2.2.0pre6 kernel and Charles L.'s (from borg.mit.edu) 2.2.7
kernel.

When I build another kernel, either from pmac repository or from
kernel.org, I get a crash in kswapd during boot. I'm not sure by I am
beginning to suspect it has something to do with the amount of swap I
have configured. I had lots of problems when I was using the old rule
of thumb 2 x Main Mem + 1 MB, which was about 257 MB for me.  I have
reduced it to 122876 kB and this seems to work better.

I have never been able to boot a SMP kernel using R5.

Hmmm...must have been half-asleep when typing that.  Yes, it's a 
Daystar nPower processor card with dual 200 MHz 604e PowerPC CPUs.

Here's what's left of the boot messages on the screen in 2.2.12 from 
CVS that I compiled on Aug 29, 1999:

The part about "Processor 1 is stuck." doesn't look good, then we get 
the big OOPS.

Any more suggestions?  I've tried booting without extensions, and with
virtual memory turned off.  I have not tried the BootX startup extension
yet, though, only the application.

One thing I'm not sure I have set up correctly is swap for LinuxPPC.  I'm
sure it's setup fine for MkLinux, but I may be missing something in this 
case.

Thanks!

Dave

Hi there,

On  31 Aug, this message from David D. Kilzer echoed through cyberspace:

This might be a shot in the dark, but I never heard of anyone
successfully compiling in standard serial support on the PowerMacs. I
tried it myself; I would get a panic upon initializing the serial
driver (exactly like above..).

So you might want to disable standard serial suport, and recompile...

The "processor stuck" message should be fixed if you do a cold boot (ie. shut 
the machine down completely).  You shouldn't have any more problems like this 
after the first successful boot.

Sounds like you have compiled something in that your computer doesn't like...
Have you tried my kernel (R5)?

I'd look into your serial driver config options. There are some that
don't work on the PPC.

And if you run the oops message through ksymoops (to be found in
/usr/src/linux/scripts/ksymoops/), you get more meaningful addresses.

Yes, I have a DayStar nPower400 card, which I assume is the same card.

I've had some interesting memory problems with mine, as well.  However,
various things like moving around the RAM, and leaving the MacOS running
for a while can magically fix problems part of the time.

I always use OF to boot, but other people say it works with BootX.

Well, this sort of thing has come up on the lists before.  You could search
the archives.  Past that, try shuffling around your hardware.  Linux seems
to be very picky about running SMP.

I'll try the cold boot trick first to see if I can 'unstick' processor 1,
and rerun 'make config' to look at the serial options more closely.

Also, I tried the borg.mit.edu 2.2.10 multiprocessor kernel with no luck.
It just stopped after "booting..." on the inital screen.

It really looks like it's breaking down in the autoconfig function of
drivers/char/serial.c. What happens if you eliminate CONFIG_SERIAL=y
from
your .config file?

(On the other hand, I see that Paul M. has CONFIG_SERIAL=m in his
standard config files. Does this mean that the serial.c stuff is
supposed to work on the PPC?)

Only with some awful hacks to disable the probing of I/O ports and to
make it start at ttyS2 instead of ttyS0.  This hack is in my rsync
trees and in the precompiled kernels I've done.  (I could post a patch
if necessary.)

It's not a good long-term solution but I needed something so I could
use the PC-card modem on my 3400. :-)

Yes!  Thanks for all the help!  This was the problem.  I removed
CONFIG_SERIAL and it booted!

Unfortunately, I still get a "Processor 1 stuck." message on boot, which
apparently makes it absent from /proc/cpuinfo as well.  This is booting
from the BootX application in Mac OS (with or without extensions loaded).

I haven't tried booting from OF or with the BootX extension yet.

Thanks again for all the help!!  (Anyone get 2.3.x to boot with SMP? :^)

I don't understand why: my PCCard modem has always worked [*] on a
