Hi,
I need to trace all data loads/stores of a guest OS running under qemu (for
now, both guest and host are x86-64, and virtual addresses should be
sufficient). Looking into qemu-devel archive I see that this subject is
brought up not very frequently, but regularly. I know, there is a general
tracing support, but I am not sure how suitable it is for such high-volume
tracing. Also, some TCG hacking is needed for this to work. Several people
has tackled with the subject, particularly, Llu=EDs Vilanova, who still may
be around in this mailing list (or should I CC him?). However, I do not see
a relevant code in git master.

Anybody knows what is a current state of guest tracing under qemu?
Any pointers to official/unofficial git repos with a (partial)
implementation?

Thanks,
Ilia.
