ROB Occupancy stat

[mihai pricopi]

Hi,

  I am trying to get the ROB Occupancy by reading the stats with this
command:

  ROB_USE=`stat-manager -per-node -d $f format-string
"<EXPR:{0$n_proc-uarch-ROB-Occupancy:Total}>" selection`

  But every time I get the value 0. Is hard to believe that the accupancy is
actually 0 unless the ROB buffer is never used. Is there a reason why the
ROB is 0 ? Maybe I`m not reading the stats correctly.

Thanks
Mihai
