From 97f5ab6651a996ecefed73e41684422f3b29d9a8 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Thu, 8 Oct 2009 10:16:48 -0700 Subject: drm/i915: add render standby support Render standy allows the GPU to power down the render unit when idle. In order for this to work, it needs a page of graphics memory to save state. This patch allocates that page and enables the feature on supported chipsets.
