The following patches against qemu.git allow static trace events to be declared
in QEMU. Trace events use a lightweight syntax and are independent of the
backend tracing system (e.g. LTTng UST).
Supported backends are:
* my trivial tracer ("simple")
* LTTng Userspace Tracer ("ust")
* no tracer ("nop", the default)
The ./configure option to choose a backend is --trace-backend=.
Main point of this patchset: adding new trace events is easy and we can switch
between backends without modifying the code.
Prerna: Would you like to add your tracing system as a backend? This would be
similar to my patches to add "simple" and "ust" backend support.
Jan: Adding kernel marker backend support should be straightforward if you are
interested.
