From f97108d1d0facc7902134ebc453b226bbd4d1cdb Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Fri, 29 Jan 2010 11:27:07 -0800 Subject: [PATCH] drm/i915: add dynamic performance control support for Ironlake Ironlake (and 965GM, which this patch doesn't support) supports a hardware performance and power management feature that allows it to adjust to changes in GPU load over time with software help. The goal if this is to maximize performance/power for a given workload. This patch enables that feature, which is also a requirement for supporting Intelligent Power Sharing, a feature which allows for dynamic budgeting of power between the CPU and GPU in Arrandale platforms.
