--- Comment #3 from Eero Tamminen <eero.t.tamminen at intel.com> ---
The bug here isn't CPU utilization, but BDW performance compared to HSW. 
DrvCtx tests mainly GL context (re-)creation speed, so large CPU usage and test
being CPU bound is *expected*.  CPU utilization just provides clue what could
be the cause for bad performance.

Mengmeng, if the CPU utilization is 90% on BDW, is it lower or higher on HSW
(when you use same GPU & CPU speed for both)?

If CPU utilization on BDW is higher, issue is on CPU side, if it's lower on
BDW, issue is GPU side.
