Hello, I would like to help debug booting AIX with qemu-system-ppc. Here is what I have so far, please let me know what further information I should provide to aid in pinpointing where the following hang occurs:

Hello Kenneth,

I would like to help debug booting AIX with qemu-system-ppc.
Recent versions of AIX are destined to fail on qemu-system-ppc. You'll need qemu-system-ppc64 and the ppc64 OpenBIOS instead.
Here is what I have so far, please let me know what further information I should provide to aid in pinpointing where the following hang occurs:
==================================================== Booting AIX in QEMU+OpenBIOS (CPU type PowerPC,750) ====================================================

I had a version of OpenBIOS on which AIX complains about the 750 and drops back to the prompt.

=========================================== OpenBIOS debug (built with CONFIG_DEBUG_*) ===========================================
You mean, you built with a different config than the one you posted above??? Anyway, the below debug output is too much and non-telling.
R: 7fb5bc80 R: 7fb5bc24 R: 7fb5bba0 R: 7fb5bbd8
IDE - ob_ide_read_blocks: ob_ide_read_blocks 7fb9f0a8 block=0 n=1 IDE - ob_ide_read_sectors: ob_ide_read_sectors: block=0 sectors=1 IDE - ob_ide_atapi_drive_ready: ob_ide_atapi_drive_ready R>: 7fb5bbd8
[...]
Despite the large amounts of debug outputs you didn't mention your command line. A standard -nographic output with the default debug config options would be much more appreciated. As stated earlier elsewhere, SVN HEAD does not yet work for AIX; patches are needed for RTAS (and QEMU).

BTW, is probably an off topic on this list, but do you know whether Slimline Open Firmware (http://www.ibm.com/developerworks/power/pa-slof/) under qemu would be an easier way for booting AIX?

Hello, I would like to help debug booting AIX with qemu-system-ppc. Here is what I have so far, please let me know what further information I should provide to aid in pinpointing where the following hang occurs:
==================================================== Booting AIX in QEMU+OpenBIOS (CPU type PowerPC,750) ====================================================
Welcome to AIX. boot image timestamp: 00:39 35/2D The current time and date: 01:10:58 04/25/2011 processor count: 1; memory size: 2047MB; kernel size:2293829 boot device: cd:\ppc\chrp\bootfile.exe [hangs here...]
After some QEMU patching I'm able to confirm this. QEMU hangs a lot on my Darwin/ppc64 host though, not just here. My Haiku/i386 guest keeps hanging for multiple seconds.
It appears there's some QEMU regression, introduced within the last four weeks. Any help bisecting/fixing would be appreciated.

Since we don't have a real IBM machine emulation yet, I haven't played with any real firmware for POWER.
I had inquired whether the recent pSeries patch series would help with AIX emulation but understood it was only used to boot a Linux kernel directly using a special SLOF.

I had a version of OpenBIOS on which AIX complains about the 750 and drops back to the prompt.
I'm still seeing the previous behavior on armel host, whereas on ppc64 host using identical OpenBIOS binary and .iso I'm observing the above hang... weird. Rules out an endianness issue.

Hmm, on my OSX/ppc64 system it's being triggered starting with -m 260 (-m 259 last working). Don't have enough memory to cross-check on armel.

And by the way, while we're on the subject, can someone please look into this change I always have to make to get OpenBIOS ppc64 to compile? :)

I had a version of OpenBIOS on which AIX complains about the 750 and drops back to the prompt.
I'm still seeing the previous behavior on armel host, whereas on ppc64 host using identical OpenBIOS binary and .iso I'm observing the above hang... weird. Rules out an endianness issue.
Hmm, on my OSX/ppc64 system it's being triggered starting with -m 260 (-m 259 last working). Don't have enough memory to cross-check on armel.

And by the way, while we're on the subject, can someone please look into this change I always have to make to get OpenBIOS ppc64 to compile? :)

I guess this should be something like ptr2cell(of_rtas_end) - ptr2cell(of_rtas_start).

First mention thereof, no error here.
Anyway, the real fix will be to change the cell size on ppc64 to 64- bit and to revert any workarounds for 32-bit ucell I applied before. That way, the size of ucell will be large enough for ptrdiff_t, too.
Now that I have QEMU working again for debugging, I'll focus on the cell issue the next days.
If you feel tempted to investigate the magic 260 further that would be appreciated. You posted logs of -m 1024, does it work with -m 259 and break with -m 260? Or is it different numbers on your host?
Cheers, Andreas

Andreas, here is the behavior I'm seeing: if I set the memory allocation to 259M, I get this fatal error just as it finishes reading cd:,\ppc\bootinfo.txt:
OFMEM: ofmem_claim 0000412c 00000040 00000000 OFMEM: ofmem_map_page_range 00004000 -> 0000000000004000 00001000 mode 00000002 OFMEM: ofmem_claim 0000416c 00ecc600 00000000 OFMEM: ofmem_map_page_range 00004000 -> 0000000000004000 00ecd000 mode 00000002 OFMEM: ofmem_claim 0fe00000 00200000 00000000 OFMEM: **** ofmem_claim failure ***!
This is the moment where it would normally print "Welcome to AIX."
But, if I set the memory to 260, it gets further along, as you stated, however it eventually hangs with the NIP (Next Instruction Pointer register) just flapping between addresses 00000000fff91ac4 and 00000000fff91ad4
Regards,
Ken

The reason no one else has noticed this ucell/ducell compiler warning is because I'm probably the only one using such a recent version of GCC as my cross-compiler. It gets caught with -Werror

Now that's interesting. The above message comes from this snippet of code here (libopenbios/ofmem_common.c:606):
if( !align ) { if( is_free(addr, size, ofmem->virt_range) && is_free(addr, size, ofmem->phys_range) ) { ofmem_claim_phys_( addr, size, 0, 0, 0, 0 ); ofmem_claim_virt_( addr, size, 0, 0, 0, 0 ); virt = phys = addr; } else { OFMEM_TRACE("**** ofmem_claim failure ***!\n"); return -1; } }
So what is happening is that OFMEM is failing to claim either the physical or virtual address for that particular section of memory. Looking further, it seems that the secret is actually in the numbers:
0xfe00000 = 266M
Because in the above code we claim both physical and virtual memory at the same address, then the above will only be valid with at least 260M of RAM.
Now I understand this better, I'm beginning to think that since these routines are called by the MMU node claim functions, in actual fact it is just the virtual address that is being specified and hence we should just allocate the next free physical address rather than creating a 1:1 virtual to physical mapping.
What happens if you change the physical allocation in the section above to the following?
ofmem_claim_phys_( 0, size, PAGE_SIZE, 0, ofmem_arch_get_phys_top(), -1 );
That should pick the next free page-aligned physical region instead, and therefore guarantee that the allocated range will lie within the physical machine RAM.
ATB,
Mark.

Changed code as requested:
if( !align ) { OFMEM_TRACE("we are here! KPS\n"); if( is_free(addr, size, ofmem->virt_range) && is_free(addr, size, ofmem->phys_range) ) { ofmem_claim_phys_( 0, size, PAGE_SIZE, 0, ofmem_arch_get_phys_top(), -1 ); ofmem_claim_virt_( addr, size, 0, 0, 0, 0 ); virt = phys = addr; } else { OFMEM_TRACE("**** ofmem_claim failure ***!\n"); return -1; }
Same result however:
OFMEM: ofmem_claim 0000412c 00000040 00000000 OFMEM: we are here! KPS OFMEM: ofmem_map_page_range 00004000 -> 0000000000004000 00001000 mode 00000002 OFMEM: ofmem_claim 0000416c 00ecc600 00000000 OFMEM: we are here!

Only now when I try -m 260 I'm getting the error either way:
OFMEM: ofmem_claim 0000412c 00000040 00000000 OFMEM: we are here!

If I put -m 512 it works:
OFMEM: ofmem_claim 0000412c 00000040 00000000 OFMEM: we are here! KPS OFMEM: ofmem_map_page_range 00004000 -> 0000000000004000 00001000 mode 00000002 OFMEM: ofmem_claim 0000416c 00ecc600 00000000 OFMEM: we are here!

KPS OFMEM: ofmem_map_page_range 0fe00000 -> 000000000fe00000 00200000 mode 00000002
If I revert back to the original code, I can use -m 260 again:
OFMEM: ofmem_claim 0000412c 00000040 00000000 OFMEM: we are here! KPS OFMEM: ofmem_map_page_range 00004000 -> 0000000000004000 00001000 mode 00000002 OFMEM: ofmem_claim 0000416c 00ecc600 00000000 OFMEM: we are here!

Hi Ken,
Ah okay - I just realised we also need to remove the is_free() check for the physical region as we are now allocating it ourselves, and plus we now need to set phys. Note that I am currently not able to compile-test until tomorrow so you may need to tweak it a little further in order to get it to work.
This is not ready for commit yet, but the following should hopefully work better:
if( !align ) { if( is_free(addr, size, ofmem->virt_range) ) { phys = ofmem_claim_phys_( addr, size, PAGE_SIZE, 0, ofmem_arch_get_phys_top(), -1 ); ofmem_claim_virt_( addr, size, 0, 0, 0, 0 ); if ( phys == -1 ) { OFMEM_TRACE("ofmem_claim failed\n"); return -1; } } else { OFMEM_TRACE("**** ofmem_claim failure ***!\n"); return -1; } }

Mark.

Okay - something strange is happening here. I tried the attached patch in order to use the standard physical memory range allocator (top down, instead of forcing phys = virt) , but this causes my test Fedora Core 12 PPC32 ISO image to hang just after "returning from prom_init".
Andreas - can you take a look at this and see if I'm doing something obviously wrong in PPC land? I can't understand why changing the underlying physical addresses causes the PPC kernel boot to fail when the same phys -> virt mappings are still in place.
I'm fairly sure this is the right fix and the patch shows no regressions under SPARC32/SPARC64...
ATB,
Mark.
