Title:
  top does not allow displaying PSS field

Status in “procps” package in Ubuntu:
  New

Bug description:
  Even though recent kernels support PSS via /proc/*/smaps, top does not
  allow displaying the PSS ("proportional set size") field.

  Computing the Pss should be similar to computing RSS, except that one
  must use Pss field from smaps.

  Shell example for computing the requested field:
  $ cat /proc/$(pidof firefox)/smaps | awk '/^Pss:/&&sum+=$2{}END{print sum/1024" MB"}'
