Subject: [Qemu-devel] How to modify QEMU to capture memory operations of the guest OS?
Date: Mon, 27 Aug 2007 23:21:01 -0400 (EDT) [thread overview]
Message-ID: <Pine.GSO.4.58.0708272319170.2425@gaia2.cc.gatech.edu> (raw)
Hi All,
I am wondering if it is possible to modify QEMU source code such that I
can log the memory operations by a guest OS. According to QEMU
documentation, it has a compiled code piece for each instruction of the
guest OS (or the simulated CPU?). Where is each instruction read and
replaced with the pre-compiled code? Is it in dyngen.c? I read dyngen.c
but can not figure out how the replacement is done. Can anybody shed light
on this process as well as how the logging could be done?
Many thanks,
Jinpeng
