The main question would be why create a tracing framework and probe
markup macros specific to QEMU ? It looks like quite a few major
open source projects (PostgreSQL, Python, TCL, OpenJDK) are using
DTrace static probe markers for code instrumentation. IIUC this
is accessible on Solaris, (Free/Net?)-BSD, OS-X and also Linux via
SystemTAP's DTrace compat layer. Is this QEMU specific probe markup
flexible enough to make it possible to also support DTrace/SystemTAP
without having to add a second set of source code markers to every
probe point ?
Regards,
Daniel
