I have = tried tracing through the code but seems this link http://repo.or.cz/w/qe= mu/stefanha.git/blob_plain/refs/heads/tracing:/docs/tracing.txt is not up= dated because many of the options do not work here. I would very happy if= someone could provide me links to a good starting point to understand QE= MU source code. The "tracing" you mentioned is not tend to help reading the code. Depen= ds on which part of QEMU you're trying to play with, you have some background knowledge of it. See "Getting to know the code" on the QEMU wiki [1].
