From 066d65db11fe4049bae52199c4b76fd6d9e95d47 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Thu, 26 May 2011 12:12:43 +1000 Subject: [PATCH] drm/nvc0/gr: calculate magicgpc918 ourselves Not a clue what it is yet, but we get the same numbers as NVIDIA now. My 465 didn't seem to care to greatly *what* I bashed into these registers..
