hallo dear linuxppc kernel developers, i'm looking for some tips to use a modern linux kernel on my old Pegasos1 G3 600MHz (IBM PowerPC 750Cxe). The last working one is 2.6.16.x with arch=ppc. a picture of the screen when it freezes loading a modern kernel: http://i52.tinypic.com/33uzgc8.jpg thank you, Nel -- Power Mac G4 AGP 450MHz - CRUX PPC (32bit) 2.7

Hi, For what it is worth, I can boot 2.6.36 on a PowerMac 8600 with a 750GX processor in it. I have to compile the kernel with gcc 4.1.2. Figuring out why 4.3.5 won't work is ... a work in progress (maybe an exorcism will help?). kevin On Sat, Mar 12, 2011 at 1:05 PM, nello martuscielli [off-list ref] wrote:

hi Kevin, thanks for your suggestion. I just tried but it doesn't work for me. I've the same freeze also compiling with the old gcc-4.1.2. Nel -- Power Mac G4 AGP 450MHz - CRUX PPC (32bit) 2.7

But if someone is capable (i don't have this skill) here what it
happens reading from serial debug console untill it freezes with

What is the last kernel version working on that machine? If you have a working kernel and can build kernels, you could try bisecting to identify the change that led to that. Perhaps then someone could have some ideas. With kind regards, -- Baurzhan Ismagulov http://www.kz-easy.com/

node = call_prom("finddevice", 1, 1, "/");
rc = call_prom("getprop", 4, 1, node, "model", model, sizeof(model));

/* 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 0xc0000000, 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 0xc0000000) phys=0\n");
phys = 0;
} else if (call_prom("getprop", 4, 1, prom_chosen, "mmu",
&prom_mmu, sizeof(prom_mmu)) <= 0) {

} 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? Gerhard -- Schon gehört? GMX hat einen genialen Phishing-Filter in die Toolbar eingebaut! http://www.gmx.net/de/go/toolbar

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. Friendly, Sven Luther

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. 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-----

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. Sadly, Sven Luther

i'm not an expert but from a quick logs comparison I saw two times the

see it only one time.
Maybe it's an usefull observation.
