From 047363f6f122af63bbe14aaa58ba275a25d74b9a Mon Sep 17 00:00:00 2001 From: Sumeet Pawnikar Date: Thu, 26 Nov 2015 13:33:13 +0530 Subject: intel/kunimitsu: Update the PL1 value as TDP Currently, the Power Limit 1 (PL1) value is 6W which is low for high performance KPIs. This patch updates PL1 value as TDP. SKL-U has 15W TDP. BRANCH=None BUG=None TEST=Built and boot on kunimitsu. Check for the PL1 value over sysfs interface "/sys/class/powercap/intel-rapl:0/constraint_0_power_limit_uw". Load the system with Aquarium 1000 Fish, average FPS should be meeting target 60 with this change.
