[parisc-linux] 715/80 problems

[Hannu Martikka]

Hei!


With 715/80 I get following:

Boot
:disk(....)/stand/vmlinux

GRs

0x00000000
...
	<bunch of HEX-values>
CRs

	<bunch of HEX-values>
SRs

	<bunch of HEX-values>
OTHER

	<bunch of HEX-values>

and then nothing...
It should be plain 715 but I have addon X.25 card on this machine (EISA?)

you might want to try to boot via tftp / bootp as this is what most of us do
and it seems to work for us.

Hannu/Goodi,
You didn't get any messages about a bad address here?

Dumping the GRs/CRs/SRs suggests a SW fault which can't be
handled...but the linux kernel needs to learn how to dump
more useful information.

BTW, those "<bunch of HEX-values>" mean something to various
people on the list. If you can collect (and post) all output
via serial console starting with the "Boot" message, others
on this list might be able to help.

I think the EISA is ignored for now...

What's the difference? I mean why should it be different?
I guess tftp/bootp uses the Image (make Image) and IPL can use vmlinux
(make vmlinux) kernel.

It can't (or at least I don't know it can).  The kernel image has to be
loaded by a boot loader, and there is reason to believe it has to be our
boot loader.

Goodi,
Are you using HP-UX boot loader?

To boot from disk, one should do "make Image" and dd the Image to disk.
This will trash the HP-UX file system so only do this on a spare disk!
The loader used is then from the parisc-linux source tree.

I was... It used to work (at the time when kernel didn't... :)

I setup the tftp/bootp server and now I can boot my 715/80 from lan.
Last thing it says is "urgh" and then it stays in for(;;). I cannot say
wether that is good or bad :)

Nope. First thing that showed up was "GRs".

I was using the IPL/HPUX loader to start kernel. Are you still interested?
It now works with tftp/bootp.

There's definitely a problem with booting off of a disk, and I'm not
sure what the problem really is.  It'd be great if someone could look
into this, I know we're not implementing the entire LIF header.

Has *anyone* been able to boot from disk?

Sorry I sent this reply to Philipp while I meant to send it to the list.

Inthe mean time I saw Alex mail, so its sounds more like a regression
than a new desgin orientation.

Correct me if I'm wrong.

I'm single node oriented for now, I use to setup my disc so I could have
all in 1, i.e a LIF area, an HFS with the development system on it, an
EXT2 area (for the future), a swap area for linux, I don't plan to boo
HP-UX on this one.

With the regression that occured after 14 september  1999, or so (20
septembre is wrong, 14 setp is good), I can't use it anymore.

I'm think about a newfs to regain the full HFS capacity unless one of
you can tell me this will be put back as it was before. For now I assume
the vmlinux is not supposed to boot from isl> hpux right?

It's *supposed to* work, but it doesn't.

Ah, okay.  This means that we should just be able to see what changed on
Sept. 14 and figure out what to fix.

Is anyone interested in fixing this?

Hi Philippe,
Hi Alex.

I´m not really sure, but maybe I know why it doesn´t boot any longer.
Phi, could you look in the file arch/parisc/Makefile in the section
LDFLAGS=-R<yyy>  if your working version has <yyy> as 0x10000 and your
non-working version has 0xC0010000. If yes, then it shows that the
hpux-bootloader isn´t able to load our kernel into the virtual space at
0xC0000000 and directly stops [segfaults?] without any message. One possible
solution could be, to patch the contents of the vmlinux-file at offsets 0x18,
(0x28??), 0x8A and 0x98 with &= 0xFFFFFFF (without C0). Please take a look in
the som.h-file, which contents have to be patched !  This way the hpux-loader
could load the kernel to the correct adress-room and the kernel
(already) automatically sets up the virtual adress-mapping.
In our own bootloader we read the contents of this header too and use the
"ADJ_LOW"-Function to get the correct adresses before loading the kernel.

Sure, maybe I´m totally wrong !

Helge Deller.
