--- Comment #5 from Eero Tamminen <eero.t.tamminen at intel.com> ---
I checked this on BYT & HSW GT3e, with yesterdays 3D stack (when tracking
another issue related to context re-creation).  While there was some drop on
BYT, the drop on GT3e was huge, at worst >100x worse performance than with
older kernel version.
