Description
The number of
cycles that the trace
and delivery engine
(TDE) is delivering
traces associated
with logical
processor 1,
regardless of the
operating modes of
the TDE for traces
associated with
logical processor 0.
This metric is
applicable only if a
physical processor
supports
Hyper-Threading
Technology and have
two logical
processors per
package.
Fraction of all
non-halted cycles
that the trace cache
is delivering μops
associated with a
given logical
processor.
