How does VTune configure itself in the case of a sampling a remote processor. Does it do it based on the local/remote processor. I'm running the controlling system on a P4 processor while the remote Linux box is a Intel Xeon with Hyperthreading.
The lower 4 bits of ESCR are either set to OxC(OS/USR mode for Thread 1) or Ox4(Usr mode for Thread 1). I want to monitor both logical processors in the Xeon machine and it does not allow me to change the lower 4 bits of ESCR to Oxf (it keeps resetting itself). I think VTune is broken in this regard.
