Title: qemu on the Z
Post by: Zazz on April 27, 2004, 05:35:21 pm

I got qemu to compile for arm host and i386 user mode (it runs i386 linux binaries on the Z but does not emulate a complete PC).
Some definitely non-trivial programs run just fine (only a little slow) so it looks quite promising.

You can download the qemu-i386 binary and further comments from here (http://zaurus.zapto.org/zazz/qemu/).

Hi Zazz, this looks great!
What programs did you try already and how do they look on the Z?

Here is a screenshot to show that I was serious about running non-trivial applications...  This is also pushing it to limits what the poor little Z can do, it is close to needing more ram or swap.

Cool!  Is that matlab?

Wow!

Is mathematica at all usable or is it too slow on the Z?  Which Z do you have?

Floating point calculations are painfully slow but symbolic manipulations (things like Simplify, Expand, Integrate etc) are perfectly usable. I have a C860.

WOW Zazz, that is impressive!

1.) OK, excuse the newbie, but what is \"qemu\"?
2.) On which kernels does this work? (I will be installing new Cacko - still waiting for my C860)
3.) Where oh where does one find the Mathematica binary, is it Commercial or GPL?

That is one of the more impressive things I have seen on a Z yet..

1) Qemu is a cpu emulator (like bochs, only about two orders of magnitude faster). There is a version which emulates a complete PC which does not (yet) work on the arm architecture and a version which runs i386 linux binaries only which works.

2) The static binary I compiled should run on anything with an xscale cpu. The binary with shared libs needs a libc version compatible with the one from pdaXrom 1.0.5.

3) It is commercial (and our campus has a site license). I guess it\'s the whole point of qemu to run commercial binaries. If you had the source code you would port it to arm directly.

Two more updates:

i) Wine still does not work (I\'m not trying too hard though).

ii) I got binfmt_misc to work and I figured out the -L switch, so now I can run i386 binaries seamlessly by simply invoking them like any other executable.

Very Great !!!
I \'m trying this on my sl5500, but it does\'nt work...
Is it no compatible with an arm processor ?
How know, if a program i386 is compatible ?
Do you have an example of a free program i386, which should work ?

totoetlititi,  A program is i386 compatible if you can run it on your pentium or AMD... i386 is INTEL 386... so anything newer than that. If you look at a site like www.rpmfind.net you will see lots of i386 programs. Still awaiting my C860, so i will try it out myself then.

Unfortunately I'm unable to access http://zaurus.zapto.org/zazz/qemu/ (http://zaurus.zapto.org/zazz/qemu/) URL.

What version of QEMU it is?

I use the old one (0.5.3) compiled by Zazz too. Very nice program.

Sure, here they are:
Dynamicaly linked (http://www.geocities.com/kai_cezar/qemu-0.5.3-armhost-i386user.zip) and Staticaly linked (http://www.geocities.com/kai_cezar/qemu-i386-static.gz)

Both was compiled by Zazz and work fine for me.
