From 42c2798b35b95c471877133e19ccc3cab00e9b65 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 5 May 2009 13:13:16 -0700 Subject: [PATCH] drm/i915: apply G45 vblank count code to all G4x chips and fix max_frame_count All G4x and newer chips use the new style frame count register, with a full 32 bit frame count. Update the code to reflect this.
