From 21188368c19d7191e83b7a6bf9fbee697fdcf026 Mon Sep 17 00:00:00 2001 From: Dirk Brandewie <dirk.j.brandewie@intel.com> Date: Thu, 19 Jun 2014 07:38:34 -0700 Subject: [PATCH] intel_pstate: Fix setting VID Commit 21855ff5 intel_pstate: Set turbo VID for BayTrail introduced setting the turbo VID which is required to prevent a machine check on some Baytrail SKUs under heavy graphics based workloads. The docmumentation update that brought the requirement to light also changed the bit mask used for enumerating P state and VID values from 0x7f to 0x3f. This change returns the mask value to 0x7f. Tested with the Intel NUC DN2820FYK, BIOS version FYBYT10H.86A.0034.2014.0513.1413 with v3.16-rc1 and v3.14.8 kernel versions.
