Maybe it's an usefull observation. Well, I never put my hands on an OpenFirmware machine, but I could imagine that this is an image loading problem. Various PPC Linux related websites suggest to set a different load base for the kernel image on Pegasos machines: setenv load-base 0x400 Does that work on the Pegasos1?

It has been age since i looked into this, but to the best of my knowledge (and i wrote the above code or at least the earlier versions) it should be still broken. Any idea then, how the workaround can be ported to arch/powerpc/ or if there is a better one available? Sorry, it has been years since i looked these parts of the linux kernel, so i don't really know how the arch/powerpc code handles this differently. Your best guess is to hunt for the code yourself, and find the place. I don't remember though if debugging at that time is easily possible though. if chrp support doesn't anymore include Pegasos1 it could be nice to remove all that dead code. Albeit it's fun that nobody cared about for it during the ppc=powerpc switch as Pegasos1 was retired in 2003 and linux-2.6.17 was released in 2006... about three years. Also, the Pegasos2 OF implementation corrected these issues. Notice that 2006 was also the year that debian sabotaged all powerpc work, and had me expulsed because some people in the debian-installer team didn't support technical critics and had more political pull inside debian than myself. This happening after almost a decade of me giving my time to debian, i kind of lost interest at that point, and nobody stepped up to take over my work. And on top of that, Franz Pop commited suicide last year, which could possibly have been avoided if debian's leadership would have showed more maturity and responsability back then. Sorry for the off topic rant, but this is something which did take a really long time for me to get over, and i believe that the debian folk are still not ready to let it go. I am still censored on debian mailing lists today and probably banned from irc channels.

On the other side you mentioned this workaround in
arch/ppc/kernel/prom_init.c to me some time ago:
unsigned long __init prom_init(int r3, int r4, prom_entry pp) :
node = call_prom(finddevice, 1, 1, /);
rc = call_prom(getprop, 4, 1, node, model, model,
sizeof(model));
if (rc 0 !strncmp (model, Pegasos, 7)
strncmp (model, Pegasos2, 8)) {
/* Pegasos 1 has a broken translate method in the OF,
* and furthermore the BATs are mapped 1:1 so the phys
* address calculated above is correct, so let's use
* it directly.
*/
} else if (offset == 0) {
/* If we are already running at 0xc000, we assume
we were
* loaded by an OF bootloader which did set a BAT for
us.
* This breaks OF translate so we force phys to be 0.
*/
prom_print((already at 0xc000) phys=0\n);
phys = 0;
} else if (call_prom(getprop, 4, 1, prom_chosen, mmu,
prom_mmu, sizeof(prom_mmu)) = 0) {
prom_print( no MMU found\n);
} else if (call_prom_ret(call-method, 4, 4, result,
translate,
prom_mmu, _stext, 1) != 0) {
prom_print( (translate failed)\n);
} else {
/* We assume the phys. address size is 3 cells */
phys = result[2];
}
Can anybody comment, if this broken translate method in the OF would
still be needed for arch/powerpc?
Well, since this is long dead hardware not produced anymore, i don't see
how the OF could have unbroken itself by moving to powerpc.
It has been age since i looked into this, but to the best of my knowledge
(and i wrote the above code or at least the earlier versions) it should
be still broken.
Any idea then, how the workaround can be ported to arch/powerpc/ or if
there is a better one available?
regards,
Gerhard

Sorry, it has been years since i looked these parts of the linux kernel, so i don't really know how the arch/powerpc code handles this differently. Your best guess is to hunt for the code yourself, and find the place. I don't remember though if debugging at that time is easily possible though.

Albeit it's fun that nobody cared about for it during the ppc=powerpc switch as Pegasos1 was retired in 2003 and linux-2.6.17 was released in 2006... about three years. my regards, Nico - -- GNU/Linux on Power Architecture CRUX PPC - http://cruxppc.org/ -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.17 (GNU/Linux) iEYEARECAAYFAk2AAvwACgkQxq34tDeO7LiAMgCfSOueU5IE+CGJQFm56C2vIQdl WpUAn1MsjAZb/nt1SFtfiB1gLdx79lwX =LULL -END PGP SIGNATURE- ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
