Hi,

I am facing a problem in counting MEM_UOPS_RETIRED event on Ivy Bridge. I
am trying to use it with the *task* command and I get following error:

$> task -i -e MEM_UOPS_RETIRED:ALL_LOADS ls
task: cannot attach event0 MEM_UOPS_RETIRED:ALL_LOADS: Invalid argument.

I am facing similar problem for all the events that have dual names in the
output of *showevtinfo* and one of them is marked "deprecated":
MEM_LOAD_LLC_HIT_RETIRED/MEM_LOAD_UOPS_LLC_HIT_RETIRED,
MEM_LOAD_RETIRED/MEM_LOAD_UOPS_RETIRED.
I have tried using both deprecated and recommended names.

What am I doing wrong?

Regards
Bhavi
