From 930a9e283516a3a3595c0c515113f1b78d07f695 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 14 Sep 2010 11:07:23 +0100 Subject: drm: Use a nondestructive mode for output detect when polling (v2) v2: Julien Cristau pointed out that @nondestructive results in double-negatives and confusion when trying to interpret the parameter, so use @force instead. Much easier to type as well. ;-) And fix the miscompilation of vmgfx reported by Sedat Dilek.
