From def9ba9cf6a8266ee1ffd72556db002c3a2663db Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 22 Apr 2010 12:39:58 -0400 Subject: drm/radeon/kms: add gui_idle callback Check to see if the GUI engine and related blocks (2D, 3D, CP, etc) are idle or not. There are a number of cases when we need to know if the drawing engine is busy.
