hi!
has anyone ever used some "real" performance monitoring tools (like papiex,
perfex, pfmon, etc.) on qemu? i'm running a debian linux and would like to
time some applications inside qemu and have tried the perfmon2 kernel-patch
(http://perfmon2.sourceforge.net/) for testing.
sadly, it does not work... dmesg tells me that the CPU is not identified
correctly ("unsupported family=6"). Now i am not really sure what type of
hardware-support the monitor relies on (i think PMU is the correct term, but
I'm not sure about that) and what CPUs are supported (dmesg tells me that
qemu simulates a Pentium M, but that's probably because I've compiled the
kernel on my *real* Pentium M).
... Ok, to cut a long question short: Is there any hardware support im qemu
for doing monitoring (that goes deeper than using "time") and has anyone ever
tested something that could work?
Thanks!
Clemens
