[Qemu-devel] [RFC 0/3] Tracing framework for QEMU

[Prerna Saxena]

Hi all,
The following patchset includes a simple implementation for qemu 
tracing. This introduces a framework for :
        i) Internal buffers for QEMU, and API for logging traces therein.
	ii) Tracepoint framework that logs traces to the buffer and also 
interprets already logged traces.
	iii) Monitor commands to display logged traces in tracepoint-specific 
formats, and also for enabling/disabling tracepoints individually.

This is *work in progress*. There are known issues that I'm chasing, 
which includes segfault that happens while transitioning from monitor to 
guest with tracing enabled. (Will appreciate any pointers if I'm missing 
the obvious somewhere :-))

Stefan,
	Thanks for your ideas on tracing ! I'm just posting out a rough cut of 
whatever I have ready ; We can take the best from both your patches and 
mine and have something running for qemu tracing. I'll take care of 
merging pieces together.

Looking forward to suggestions..
