From 06b6476d6b291473d0928ed242158a001d50c0f0 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 5 Jan 2010 11:27:29 -0500 Subject: drm/radeon/kms: detect sideport memory on IGP chips This detects if the sideport memory is enabled and if it is VRAM is evicted on suspend/resume. This should fix s/r issues on some IGPs.
