xentrace: fix tracing for 64bit guests
Is this an incompatible change (a brief scan made it seem so) ? If so,
it probably needs a ChangeLog entry
It mostly adds additional tracepoints (marked by bit 8 as 64bit capable)
and changing the CPUID trace, which was broken before (so this is more a
fix). The user-space end of the traces is xentrace_format with the
respective formats file, which I also changed. Otherwise I tried to be
compatible.
Given the fact that this was broken since at least February or so, I
don't think that anyone seriously uses tracing and could be concerned
about such changes. There are still some tracepoints logged but not
interpreted by xentrace_format, I will send a patch later.
BTW: Has anyone tools for analyzing traces? Does someone use tracing
regularly?
Regards,
Andre.
