Hi,
I am new to QEMU. But I got some problem so that I want to figure it out.
So I try to debug qemu to see what happened.
And I found trace framework. I think this will help me understand the point.
So I compiled qemu with option:
## *--enable-trace-backends=simple*
And did as the docs/tracing.txt tell. But when I execute the example
command in it, nothing just happens.
*./scripts/simpletrace.py trace-events-all trace-xxxxxx(my trace file
produced by qemu)
I am not sure what happened. Just ask this.
Any clue will be appreciated. Thanks in advance.
