[qemu] How can I save the values taken by EIP ?

[fiveayem]

Hello,

I am currently testing my OS on qemu, and a have a big problem. At some moment, I get a page fault exception with a faulting address 0. I realised that this value is that of EIP. I do not know how the instruction pointer got to 0, I ignore which instruction is responsible for it.

Then I would like to know if it is possible using qemu to trace EIP value along execution. This would useful to debug.

Thanks for your help.

Look up how to debug in bochs. A friend of mine recommended bochs to me months ago because of its debug capabilities. Im glad he did.
