Hi Ali,
Thank you very much for your reply. Could you please tell me how to use
the trace-flag to see when the
kernel thread info struct changes from one thread to another thread?I mean
which specific flag is for that.
It's the Thread flag, --trace-flags=Thread. However we recently discovered
that there's some code that option depends on in sim/vptr.hh that is broken,
so in the short term it won't do you any good.
The reason that I think there are two cycle counts because each cpu has
its own CPU cycles like
system.cpu0.numCycles. Except that we still have sim_ticks which is
nearly equal to the
system.cpu0.numCycles. And sim_seconds=sim_ticks/1THz. Since we only have
CPU cycle counts,how
can we use it to be divided by the system frequency?
The numCycles for the CPU object is the number of ticks that the CPU is
active (not disabled or waiting to start up). Typically that should be the
same as (or very nearly the same as) sim_ticks, which is the total number of
ticks in the simulation. They are the same tick units though.
Thanks a lot for your help.Best wishes to you!
