Re: How to set up a new processor in Qemu

Hm, this gives an error after an hour :? .
It is, that older gcc have now knowledge of newer ones :mrgreen: .
So, I did again, now after the same configure as before with

Code: Select all

make bootstrap

Re: How to set up a new processor in Qemu

Ok, I make a try to set up a new processor and may be the whole Raspberry board in qemu-0.9.1 I think, with this qemu-0.9.1 even WINE has a big chance. For this I install the Compiler gcc-3.3.6 with configure ./configure --enable-threads=posix --march=armv6zk --prefix=usr/share/gcc-3.3.6 When I star...

Re: Win95 on real Raspi

Hi all,
the qcow2 format from Qemu seems not to start on Raspi.

So use the raw format from Qemu. You can transform a qcow2 into a raw format with qemu-img,

Code: Select all

qemu-img convert -f qcow2 -O raw win95.qcow2 win95.img
Have a nice day,

Re: How to set up a new processor in Qemu

May be qemu-0.9.1
is a better startingpoint for optimization.
This qemu-0.9.1 was the last version,
which make use of dyngen and not of TCG,
have a nice day

Re: How to set up a new processor in Qemu

Hm, not an advantage :? With -cpu arm1136-r2 it tolds VFP support v0.3: implementor 41 architecture 1 part 20 variant b rev 4 and with -cpu arm1176 it tolds VFP support v0.3: implementor 41 architecture 1 part 20 variant b rev 5 Bogomips are from 37...39 so, this was not a big step forward :mrgreen:...

Re: How to set up a new processor in Qemu

Boottime of the Raspian image in Qemu on raspi is more than 30 min. This is really crazy, because boottime of full XP is 9 min on real Raspi. So, it is just not true, that qemu needs a lot of time to make x86 binary code from ARM, Dietmar PS: The overhead from the intermediate, processor independ TC...

Re: How to set up a new processor in Qemu

Hi, I compared qemu 15.1 with qemu15.50 from Thoronir. Qemu15.50 was the first qemu with Arm1176 CPU support. There I did a binary compare with Beyond Compare 2 :-). Very astonishing, what small things have been changed to enable a new CPU. This is from target-arm\helper.c (means for ARM Guest, fron...

Re: Win95 on real Raspi

Hi meigrafd, this error is because of a bug in qemu, how to manage memory. This is gone after new start. Just try again SOME TIMES without -m 92 switch or try other -m or change -cpu. I also did not succeed to boot a new Wheezy I386 from Raspi to Desktop via any qemu, but I think it is the fault of ...

How to set up a new processor in Qemu

Hi all, I read http://home.dei.polimi.it/sami/architetture/godson.pdf where is described, how to achieve 70% of native binary Power with Qemu x86 emulation from Mips processor Loongson-3. They use about 5% from chipdesign for this. So my idea is really simple: Set up a complete new processor in Qemu...

Hallo THS, ich benutze die Raspbian Version vom 16. Dezember 2012. Was passiert, wenn du jetzt ./qemu eintippst? Es müsste sich das Qemu Fenster öffnen, auch ohne win95.img Datei. Das funktioniert aber nur nach startx Eingabe wegen SDL Ausgabe in Qemu. Ich kann auch mein komplettes Raspbian Image au...

Re: Win95 on real Raspi

Hi THS,
./qemu = Permission Denied
just go to the folder, where this qemu stays and type from this folder in commandline

Code: Select all

chmod 777 qemu
this works,
Moorhuhn and Settlers 2 are playable like normal with sound,

that it may be just enough to copy the executable

to the folder /usr/local/bin of your working Qemu
