From 84b8081c2baf84b52ac9bf79f07edcea975ab0b5 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Tue, 26 Oct 2010 02:17:56 +0200 Subject: [PATCH] drm/nouveau: Don't use load detection for connector polling. Analog output polling makes GL programs jerky when pageflip is being used because it's carried out with the mode_config mutex held.
