operating systems that I'm able and not able to run on QEMU PPC
by Massimo Montecchi 15 Sep '10

15 Sep '10

Here is the lists of operating systems that I'm able and not able to run on QEMU PPC: - DEBIAN 5.0.5 PPC it works - OPENSUSE 11.1 PPC it works - FreeBSD 8.1 PPC hangs (see below details) - NETBSD 5.0.2 PPC and PPC64 does not load with defaults (see below details) - SLES 11 SP1 PPC does not load with defaults (see below details) - AIX 4.3.3, 5.1 and 6.1 do not load (see below details) Some time ago I remember that the "working" OSs was more that now :-( -- Cordiali Saluti/Best Regards Massimo Montecchi Modena - Italy DETAILS: ------------------------------------------------------------------------------- FreeBSD 8.1 PPC >> ============================================================= >> OpenBIOS 1.0 [Aug 17 2010 14:41] >> Configuration device id QEMU version 1 machine id 2 >> CPUs: 1 >> Memory: 1024M >> UUID: 00000000-0000-0000-0000-000000000000 >> CPU type PowerPC,750 Welcome to OpenBIOS v1.0 built on Aug 17 2010 14:41 Trying cd:,\\:tbxi...

corrections to vocabulary.fs
by Programmingkid 15 Sep '10

15 Sep '10

I found a few documentation mistakes in the vocabulary.fs file. In the comment section of get-order and set-order, their comments are incorrect. For get-order the comment should be ( -- widn .. wid1 n). For set-order the comment should be ( widn .. wid1 n -- ). This page is where I found the correct comments: http://lars.nocrew.org/dpans/dpans16.htm#16.6.1.2197

I just tried `qemu-system-ppc64 -boot d -cdrom dvd.AIX6_OpenBeta....iso` and it hangs after: Welcome to OpenBIOS v1.0 built on Sep 9 2010 19:56 Trying cd:,\\:tbxi... On a real PowerMac G5 neither the above nor the ppc\bootinfo.txt command `boot &device;:\ppc\chrp\bootfile.exe` worked, any variations of it with , and/or :0 etc. lead to errors about no FDisk partition found or noninterposed LOAD not supported, iirc. This is what -nographic shows me: >> Cannot manage 'OHCI USB controller' PCI device type 'usb': >> 106b 3f (c 3 10) >> ============================================================= >> OpenBIOS 1.0 [Sep 9 2010 19:56] >> Configuration device id QEMU version 1 machine id 3 >> CPUs: 1 >> Memory: 128M >> UUID: 00000000-0000-0000-0000-000000000000 >> CPU type PowerPC,970FX Welcome to OpenBIOS v1.0 built on Sep 9 2010 19:56 Trying cd:,\\:tbxi... @Alex, any hunch what the OHCI thing is about? It doesn't appear with qemu-system-ppc. Some USB initialization missing in the QEMU U3 machine init maybe? Regards, Andreas

I was really hoping for translating the compile-time code into the run-time code I have presented. I made some code examples that I would like to obtain some feedback on. Tell me which of these run-time code examples seems the most plausible to work. Example 1: compile-time code: : myword { ; dog cat hamster } 4 -> dog 3 -> cat 1 -> hamster dog @ cat @ + hamster @ + cr " animals = " . cr ; run-time code: : myword \ Note: myword_wordlist and standardlist are raw numbers - not variables myword_wordlist standardlist 2 set-order \ setup dictionary search order definitions variable dog variable cat variable hamster 4 dog ! 3 cat ! 1 hamster ! dog @ cat @ + hamster @ + cr " animals = " . cr standardlist 1 set-order \ restore dictionary search order definitions ; Another possible run-time code translation: : myword variable dog variable cat variable hamster 4 dog ! 3 cat ! 1 hamster ! dog @ cat @ + hamster @ + cr " animals = " . cr forget dog forget cat forget hamster ; Example 2: compile-time code: \ assigning top stack value to variables : myword { dog cat hamster } dog @ cat @ + hamster @ + cr " animals = " . cr ; run-time code: : myword variable dog variable cat variable hamster dog ! cat ! hamster ! dog @ cat @ + hamster @ + cr " animals = " . cr forget dog forget cat forget hamster ; In each example, the compile-time code would be something that the user enters or is found in a boot script.

Hi, the last time I tried to boot AIX (6 or 7 monthes ago...), OpenBIOS was able to load the bootloader but as RTAS is not provided by OpenBIOS, bootloader failed and didn't go further. I think it was with the CHRP emulation. Regards, Laurent Hi, I have tried qemu from 0.11 to latest git (as of 11/09/2010) with latest openbios inside, but if i want to use PREP PPC "machine" the error is the same: qemu: hardware error: PowerPC 601 / 620 / 970 need a 1MB BIOS CPU #0: NIP 00000000 LR 00000000 CTR 00000000 XER 00000000 MSR 00000000 HID0 00000000 HF 00000000 idx 0 TB 00000000 00000000 DECR ffffffff GPR00 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR04 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR08 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR12 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR16 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR20 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR24 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR28 0000000000000000 0000000000000000 0000000000000000 0000000000000000 CR 00000000 [ - - - - - - - - ] RES 00000000 FPR00 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR04 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR08 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR12 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR16 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR20 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR24 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPR28 0000000000000000 0000000000000000 0000000000000000 0000000000000000 FPSCR 00000000 SRR0 00000000 SRR1 00000000 SDR1 00000000 How can I use openbios to start an AIX with qemu ? -- Cordiali Saluti/Best Regards Massimo Montecchi Modena - Italy -- --------------------- Laurent(a)vivier.eu --------------------- "Tout ce qui est impossible reste à accomplir" Jules Verne "Things are only impossible until they're not" Jean-Luc Picard

help with compile/run-time code
by Programmingkid 13 Sep '10

13 Sep '10

I need a little help on how to take compile-time code and change it so that it executes a different set of code at run-time. I want to take this code: "4 -> cat" and change it to "4 cat !" at run-time. The "->" word needs to be able to do this. Would anyone know how? compile time: 4 -> cat run-time: 4 cat !
