Hi!

I checked out the current cvs version of qemu to test the SPARC system 
emulation. Unfortunately, I was unable to boot a linux kernel. As I read in 
the archives, this mode is far from being complete, but may boot a kernel 
partly. Where can I find more information about this mode and possibly 
required patches or a kernel .config file? I tried the steps described in 
http://lists.gnu.org/archive/html/qemu-devel/2004-09/msg00308.html

Trying to boot Linux results in the following message:
chk_timer: unserviced 14 percpu.tbt 0x4040 master.tbt 0x10080

regards,
Joerg

Hi,

There are still bugs in the Sparc system emulator, currently it is not 
usable for anything.

The best I can get with CVS+patches is a trivial user-space program printing 
"Hello World!". Anything more advanced, like /sbin/init or /bin/bash crashes 
after a few system calls.

Here's a screenshot, its made with Linux 2.6.11 + a TCX patch from 
sparc-linux list, also Proll has some fixes.

Can't this be because the "Hello world" program is being used as init
and terminated? I certainly do not know, it's just an idea =)

I think he is saying that anything other than a "Hello World" program
crashes (ie /sbin/init or /bin/bash), whereas Hello World does run, and
then succesfully terminate without causing a crash :)

Are you working on this bugs, or maybe somebody else? Currently, qemu seems to 
be the only freely available sparc32 emulator.

This looks quite good, except for the last two lines :-) Where can I find the 
required patches?

Jörg

Hello,

I wish to emulate a SPARC32 machine on my x86 running linux (2.6.8).  I currently have qemu 0.7.0 running and am able to use user SPARC emulation for simple programs.  I do not require extensive SPARC CPU support (network, pci, etc..) mainly wish to have a limited OS executing.  Is the current status of qemu capable of accomplishing this?  I have tried the SPARC image available on the QEMU website without success (it loads the kernel then stops at PROMLIB).  Any help or information would be most appreciated.
 
Thanks,
Joern.

Strange: on my PC sparc-test-0.2.tar.gz is working perfectly (both the 
qemu-nog and qemu-g scripts)... Do other people have the same problem ?
