[Qemu-devel] qemu 0.9.1

[ozer ozdemir]

I'm project student from hacettepe university from turkey. i should use qemu to develop my project and i need to know that if qemu has function to return cycle number of instruction and to communicate other qemu processes. 

if it has, will you show how they can be used with examples ?

thank you for your all helps.

P.S  i am using qemu 0.9.1  cross compiling with gcc

You mean, something like rdtsc() of i386 instruction? or do you want
to count how many "virtual cycle" needed when executing certain op?

AFAIK, qemu is not cycle accurate, so even you get that "virtual
cycle" number, it won't be consistent.

Hi to alll, 

I'm a student of University Rome Sapienza.

I'm working with qemu 0.9.1 for my thesis

and  I'm trying to understand how  a full-emulation (qemu without kvm or kqemu) Virtual Machine works at low level.

I studied  your smart source code but I don't understand

how qemu manages emulated operation operands.

In particular I would like to be able to access such operands at instruction emulation time.

Could you please point me to where can I get some more specific information on that?



thanks in advance,

You would be more likely to get answers if you were using a more  
recent version of QEMU. v0.9.1 was still using dyngen instead of TCG  
technology.
