From 08ff73341f9d5bde2d5e54bfe4d6a3d2a3f2ee83 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 21 Dec 2009 14:33:52 +1000 Subject: [PATCH] drm/radeon/kms: fix crtc vblank update for r600 In 2.6.32.2 r600 had no IRQ support, however the patch in 500b758725314ab1b5316eb0caa5b0fa26740e6b to fix vblanks on avivo cards, needs irqs. So check for an R600 card and avoid this path if so. This is a stable only patch for 2.6.32.2 as 2.6.33 has IRQs for r600.
