kdb_v21 branch updated to -pa26, and kallsyms cross-compile

Parisc,

All the changes from -pa24 to -p26 have been merged into the kdb-v21 tree (that Randolph graciously started!). Thanks go to bame's recipe!

A few tests show that it is equivalent to the patches I had produced (fixes to traps.c for the soft power button).

If kdb is your bag, then it should all be set to go!

---

On another note... until I get a really fast PA box, I'm going to be cross-compiling all the time. There are issues cross-compiling a kdb'd kernel, and the problem is called 'kallsyms'.

After a bout of idiocy and help from Jess I had a cross version of kallsyms (never forget to 'unset CC').

It seemed like I was home free, except that I ran into the same problem as before (even with the supposed _new_ cross kallsyms).

.tmp_vmlinux1: ELF file .tmp_vmlinux1 not for this architecture

I check ./src/modutils/obj/obj_load.c and find:

  if (f->header.e_ident[EI_CLASS] != ELFCLASSM
      || f->header.e_ident[EI_DATA] != ELFDATAM
      || f->header.e_ident[EI_VERSION] != EV_CURRENT
      || !MATCH_MACHINE(f->header.e_machine))
    {
       error("ELF file %s not for this architecture", filename);
       return NULL;
    }

So I breakup the values and test individually...

.tmp_vmlinux1: ELF file .tmp_vmlinux1 not for this architecture (!MATCH_MACHINE)

The MATCH_MACHINE macro is pretty dumb.
#define MATCH_MACHINE(x) (x == EM_PARISC)

printf what e_machine header is set to:

ELF e_machine header is 3840
.tmp_vmlinux1: ELF file .tmp_vmlinux1 not for this architecture (!MATCH_MACHINE)

I'm not sure I've _ever_ seen a EM_??? value that big (EM_PARISC=15). A closer inspection reveals that 3840 is 15 but byte swapped.

Which leaves me wondering... what else is going to be bytesex broke in a cross modutils?

Is anyone familiar with modutils?
What would be a good way to include some cross-kallsyms support?

I can't get it to boot on my C110 - it gets stuck at the old familar "if this is the last message you see" message. I can run the Debian 2.4.18 kernel OK on this box.

Any ideas anyone?

patrick

I have it running on a C110 currently. It was installed however on a 712/100 and drive was copied and kernel recompiled for the 7200 series CPU. Are you running graphic or serial console? I am running serial console only.

MaShaun Jones

Serial. I've tried leaving after boot to see if it comes up but I can't see it but nothing seems to happen (can't ping the box).

Could you send me your .config (or even the kernel!) please?

patrick

What gcc version are you using to compile your kernel? What kernel parameters have you appended? What version of modutils are you using?
Send your .config?
Serial console?

Helpful is the documentation can be found at:
http://oss.sgi.com/projects/kdb/

c.

3.0.4, this is a Debian "woody" installaion.

Just the defaults added by PALO (which include console=ttyS0)

2.4.15 FWIW

Attached

yes

I've used KDB before on intel machines (until I discovered kgdb!) I was hoping to find a kdb patch for parisc on that site so I could apply it to a known, working kernel but there only appears to be intel & sparc ones.

I've had a good play with this last night and it seems to be the kernel config but I'm not sure why. I copied the .config from the working Debian kernel, did a "make oldconfig" and built it but...

Anyway. I plugged in a monitor and keyboard so I could see what's really going on and I can see that the kernel /does/ boot but it can't find the FW scsi controller and therefore the root filesystem.

So the problem is that I seem to have have configged out the serial console and the SCSI controller but I'm not sure how. It must be something stupid I've done but I can't see it.

Honest, I've built Linux kernels for sparc, alpha, intel and mips before, but this one's beaten me!

CONFIG_KALLSYMS=y

Here's your problem:
...
CONFIG_KDB_OFF=y
...

Either set that to 'CONFIG_KDB_OFF=n'
or boot with 'kdb=on' as a kernel paramter. (Checkout the help text in the kernel hacking option).

Some of this stuff changed in the latest kdb version.

I'm not sure why the kernel can't find the FW scsi controller. That will be problem number two :)

c.

That's only set like that as a last-dich attempt to get it to work :-(

I'm going to have to give up on this, I can't spend all week trying to get it to work. What I don't understand is that I move a working .config to the new kernel source and both the serial console AND the scsi stop working.

Ah well, it was a nice idea while it lasted. It's just a bit hard debugging code when the only error you get is "Stack pointer and cr30 do not cor respond" repeated endlessly....

patrick

You can't always copy a .config from kernel to kernel. The kernel source dictates what will be _in_ the .config. I usually run 'make mrproper' and then have 'make oldconfig' or 'make ???config' recreate the config files to suit the material in the kernel.

When switching to a new source tree I recommend:
make mrproper
make oldconfig
make menuconfig (to suit your tastes)
...

As for the endless 'Stack pointer and cr30 do not correspond!'....

I believe that is a bug in traps.c and I have code to give a proper dump. I haven't been able to get anyone who knows to explain how the dump_stack in traps should _really_ work :)

AFAI understand the following works (I've tested it on my kernels with what looks to be a successfull dump while doing some bad things (props to Bame for helping me out) ;)

BTW, what led me to this solution is that the printk in the else is completely bogus... so I rewrote the else.

Q: When do you get 'Stack pointer and cr30 do not correspond'?

Oh, I'm doing that. I just tried it again, it was either that or throw it out of the window.

Is there parisc version of the kdb patch I could try applying to a kernel source I know works maybe ?

Thanks, I'll try that out.

When it hits my buggy code :-)

patrick

We are trying not to maintian patches but rather a branch of the kernel representing common-2 + parisc specific kdb changes.

Look at this if you want to see the patch method:
http://lists.parisc-linux.org/pipermail/parisc-linux/2002-May/016246.html

The kdb_v21 branch is where all the changes and fixes will go :)

c.

I can understand the logic of that and if it worked for me I would regard it as the best solution to the problem if maintaing two sets of patches.

Thanks, I'll try that on my Debian kernel and see what happens. Despite my frustrations I really do want to get kdb working on this box. I like my HP box a lot and I've got some kernel code that really does need fixing for that platform.

+ we have a long weekend off coming up here in Britain and it's the perfect diversion for that essay I really have to write ... :-)

patrick

Hmmm

CONFIG_KDB=y : no serial console or FW SCSI
CONFIG_KDB=n : all works fine.

bizarre!

patrick

Yes, exactly the same results. There's some thing different about the binary vmlinux thatmay, or may not, be relevant. The kdb one seems to have fewer segments than a non-kdb one:

(total segment size: 3014028)

Patrick

Yes. Something is broke.

I just recently cleaned up my src trees and rebuilt a kdb enabled kernel and I get the same result on my 712/60.

/me puts thinking cap on...

The _interesting_ thing would be to diff the System.map's for kdb-on vs. kdb-off to see is anything is explicitly being removed.

I'll start a build going.

c.

I'm glad it's not just me :-)

My guess was the the scsi __init functions were not getting called for some reason, I have the System.map files for both builds but they both look OK (not that I ful understand the kernel __init system though)

patrick

Yeah, I've run through the kdb and non-kdb builds and everything is okay.

I think there are two maybe three places where kdb initializes certain structures during startup. I'm going to have to check those paths to see how far it gets before dying.

Any comments from the crowd would be helpfull :)

/me goes off to add some printk's and extra checks c.

i've been offline for a bit so i might have missed something... but aiui the symptom you've been seeing is that it hangs at the "If this is the last message you see" message? has anyone tried to compile a kernel with early bootup messages (there's a #define in pdc_cons.c to enable this) and see if they get farther?

there are some debugging stuff that you can turn on in arch/parisc/kernel/unwind.c ... that piece of code has caused some hangs in the past, you might want to enable those printks as well.

Hi Randolph,

I remember that I do it when you suggest it and iirc it help to goes further in the boot. But I could not confirm at 100% because I had some hpmc problem with my b2000 test server. Sorry, i will try to solved this problem first then come back to you.

Yeah I've seen the code in pdc_cons.c, but I didn't know about the issues with the stack unwinding (though I just read JDA's comments in the code... so I'll look at that).

I'll hack on this tonight and see how far I get. Currently my test box is turned off, and since I haven't built my remote power switch (spp + solid state relay) .... I can't reboot the sucker :}

Thanks to the external led I know that the box (712/60) doesn't get far since it never reaches the pdc soft power button initialization routine (__init power_init).

c.

The odd thing is that is just seems to disable the FW SCSI and the serial console. If I hook up a monitor (rather a feat of equopment mbving in my house unfortunately!) I can see the boot getting as far as failing to mount the root filesystem.

patrick

Hi all,

It seems that the b2000 I used to test gcc-3.2 does not crash anymore :) with all kernels :)) (pl 2.4.18 or my stuff on 2.4.19)? (I feel that fs corruption occurs and was not detected immideately?)

Well I come back to you to see what should be the useable kdb config (to investigate the network problem with kernel compiled with gcc-3.1 or -3.2).

Mine is now:
CONFIG_MAGIC_SYSRQ=Y
CONFIG_KDB=Y
CONFIG_KDB_MODULES=Y
# CONFIG_KDB_OFF IS NOT SET
CONFIG_KALLSYMS=Y

Thanks a lot,
Joel

Joel,

            ^^^^^^^^

                               ^^^^^^^^^^

Can you find that address in your System.map to verify where that is? If it's in unwind_table_init then the 'end[-1]' fix might be what is needed.

For some reason device detection becomes bogus and broken with kdb enabled. So far we've seen SCSI, Serial, PCI/EISA all die with kdb enabled. Maybe they're not dead and just moving _really_ slowly.

I'm going camping this weekend, so it's anyones game until Monday afternoon (which I have off too!!) :)

c.

Hi C,

Two news (a bad and a good as usual).

I had actually an hardware problem with this test b2000 so that I could not any more reboot it.
So the bad news is that I could not verify anything right now.

For the good news is that we have maintenance contract and the problem occurs now during the launch of stm under hpux.

So I can open a call and pieces are already order to repair it Monday.

Quoting "Carlos O'Donell Jr." <[email protected]>:

I will check it asap and let you inform

Have a nice week-end,
Joel
