From 04e4e888558ebe5d9701e31bba61d4e256ab71a8 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Mon, 12 Feb 2018 11:50:47 -0800 Subject: [PATCH] platform/x86: intel_turbo_max_3: Remove restriction for HWP platforms On systems supporting HWP (Hardware P-States) mode, we expected to enumerate core priority via ACPI-CPPC tables. Unfortunately deployment of TURBO 3.0 didn't use this method to show core priority. So users are not able to utilize this feature in HWP mode. So remove the loading restriction of this driver for HWP enabled systems. Even if there are some systems, which are providing the core priority via ACPI CPPC, this shouldn't cause any conflict as the source of priority definition is same.
