But, I think more better to call idle_loop() in locore.S.  This reason
is our stack space more than free in cpu_hatch().

# I don't know PA-RISC assembler.  X-<
Maybe, it is more better?

Do you have a patch you'd like reviewing?



There's quite a lot of work needed in pmap and trap handlers for full MP 
support.

GENERIC.MP hangs

KIYOHARA Takashi — 2013-04-01T15:27:53

Hi! Nick,


GENERIC.MP hangs in percpu_alloc().  cpu0 waits cpu1 into idle_loop().
However cpu1 doesn't go idle_loop() on hp700 in
arch/hp700/dev/cpu.c:cpu_hatch().

Please see other archs:
  x86/x86/cpu.c
  powerpc/powerpc/locore_subr.S
  arch/arm/cortex/a9_mpsubr.S

x86/x86/cpu.c:cpu_hatch() ---
void
cpu_hatch(void *v)
{
:

aprint_debug_dev(ci->ci_dev, "running\n");

idle_loop(NULL);
KASSERT(false);
}
--- x86/x86/cpu.c:cpu_hatch()

powerpc/powerpc/locore_subr.S ---
ENTRY(cpu_spinup_trampoline)
:

bl_C_LABEL(cpu_hatch)
mr%r1,%r3
b_C_LABEL(idle_loop)

ENTRY(cpu_spinstart)
:

bla_C_LABEL(cpu_hatch)
mr%r1,%r3/* move the return from cpu_hatch to the stackpointer*/
b_C_LABEL(idle_loop)
--- powerpc/powerpc/locore_subr.S

Please fix. :)

However,
Oops,  hangs again for another reason after resolved this problem...  X-<
probably I will report again in several months.

Thanks,

It's not even getting that far. I'm 99% certain that the kernel, if loaded,
isn't being executed.

As a test I tried OpenBSD 5.2's LIF image and got multiuser without any
trouble. Digging further, I found that netinstall.lif from version 4.0 in the
NetBSD archives also boots without trouble. I suspect a bootloader bug.


It may or may not be relevant, but I'm not running this system with a serial
console - it's got keyboard and mouse. This is why I haven't posted the full
output. I tried to photograph the screen with my smartphone but it's too blurry
to read. I'll be (hopefully) borrowing a friend's DSLR for an unrelated task
soon and can send it to you then.

In the meantime, I'll try to find the latest NetBSD LIF image that boots.

Re: Netbooting Trouble with 712/100

Nick Hudson — 2013-03-04T07:55:45

Can you post the full boot output and try to add the debug flag (-d) to 
the boot. Hopefully,
we can set  breakpoints to see how far it gets.

I've learned a lot about the TFTP protocol these last few days...

1) Solaris 10's TFTP server implementation and the HP712 aren't compatible. the
HP wants an option that Solaris doesn't implement.

2) Using Wireshark during boot, it appears the entire LIF file is being
transferred.

3) After downloading the LIF onto another system using tftp, the md5sum matches
what's on the tftp server.

..and I still get that 'btlb' output mentioned above just before a hard hang.
No I/O error messages though.

It seems to be loading the kernel, and then something goes wrong before the
kernel runs. I doubt it's a hardware problem as I get a working install of
HP-UX 10.20 if I boot from disk; It even starts X11 with CDE.

Great!!
SYSNBSD boots on my J6700 for

Also I try to boot GENERIC.MP next day.

Thanks for your commit.
However oops, my action is very slowly. X-<

I not yet test GENERIC with your patch.  My j6700 firmware transfers
very slowly.  And my LIF image 10Mbyte.  I am waiting about 2h...
Also firmware give ups with I/O error.... hmm...

I will more try this weekend.

This looks like a truncated file on the tftp server to me. Or maybe too 
many errors on download?

Same (truncate download)

Thanks for the fast reply, Nick!



This was the critical hint I needed, I found the issue in the DHCP server
settings and got it to get it's bootloader.

I'm getting a different issue now, however. If I do nothing, the bootloader
spits out this error message:

open lf0a:netbsd Input/output error

..and tries again on an endless loop. Manually typing in 'lf0a:netbsd' usually
fails with the same, but adding one of the prompted options (like -c) goes just
a bit further:

Start < at > 0x2000000 [1=0xf0e000-0xf0e45c]
btlb info: minsz=128, maxsz=16384
btlb fixed: i=0, d=0, c=8
btlb varbl: i=0, d=0, c=0


This was with trying the SYSNBSD file from 6.0.1; results with trying
netinstall.lif and from SYSNBSD from 6.0 were similar.

Here's an entry I have to netboot my b160l

host stan {
         # HP/9000 b160l
         hardware ethernet 00:60:b0:18:95:14;
         filename "b160.lif";
         #filename "C7120023.frm";
         next-server     arthur;
         server-name     arthur;
         option root-path "/usr/exports/stan/root";
         fixed-address stan;
}



I guess the reply isn't liked.

It should report the tftp server where the kernel is held.
