Revision 584ee3dcb1d6232857c1e38bb28d9f6bf0ec89f5 authored by Alexandra Yates on 18 November 2015, 22:58:40 UTC, committed by Rafael J. Wysocki on 25 November 2015, 22:37:44 UTC 
intel_pstate: Fix "performance" mode behavior with HWP enabled
 
If hardware-driven P-state selection (HWP) is enabled, the
"performance" mode of intel_pstate should only allow the processor
to use the highest-performance P-state available.  That is not
the case currently, so make it actually happen.
