Hi Prathap,
I have already implemented pseudo instructions for the ROI. The code is the
following:
//
// Mark beginning of ROI in simulated programs
//
void
roibegin(ThreadContext *tc)
{
DPRINTF(PseudoInst, "PseudoInst::roibegin()\n");
resetstats(tc, 0, 0);
}
//
// Mark end of ROI in simulated programs
//
void roiend(ThreadContext *tc)
{
dumpresetstats(tc, 0, 0);
exitSimLoop("roiend");
}
As I've said I would like to have a global variable that I can change in
these functions and have it be available in src/mem/cache/base.cc. I'm not
sure I understand the second part of your answer.
Cheers,
Victor
