From 8082400327d8d2ca54254b593644942bed0edd25 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Thu, 10 Sep 2009 15:28:06 -0700 Subject: drm/i915: framebuffer compression for pre-GM45 This patch adds framebuffer compression (good for about ~0.5W power savings in the best case) support for pre-GM45 chips. GM45+ have a new, more flexible FBC scheme that will be added in a separate patch. FBC can't always be enabled: the compressed buffer must be physically contiguous and reside in stolen space. So if you have a large display and a small amount of stolen memory, you may not be able to take advantage of FBC. In some cases, a BIOS setting controls how much stolen space is available. Increasing this to 8 or 16M can help.
