From 06e5598fce5ce89fe8bf081398296e5b08d993dd Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Tue, 18 Dec 2012 10:31:26 -0800 Subject: drm/i915: Move GSM mapping into dev_priv This removes an unused field from the AGP structure and moves it into the dev_priv structure (with a slightly better name). This builds upon the kill-agp series already merged. GSM is a well defined term in the bspec: GSM: Graphics Stolen Memory GTT stolen space is defined for storage of the GFX GTT entries in physical memory. IA can not access GSM directly , it can only access via GTTMMADR. GT can access GSM directly or through GTTMMADR. This is not the entire stolen space.
