From 4c7886791264f03428d5424befb1b96f08fc90f4 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Fri, 20 Nov 2009 14:29:23 +0100 Subject: drm/radeon/kms: Rework radeon object handling The locking & protection of radeon object was somewhat messy. This patch completely rework it to now use ttm reserve as a protection for the radeon object structure member. It also shrink down the various radeon object structure by removing field which were redondant with the ttm information. Last it converts few simple functions to inline which should with performances. airlied: rebase on top of r600 and other changes.
