From 5ca58282089b11f64b911618036ee7676f12735b Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 31 Mar 2009 14:11:15 -0700 Subject: drm/i915: add VGA hotplug support for 945+ Add VGA port hotplug detection to the i915 driver. When KMS is enabled, plugging in or removing a VGA cable from the VGA connector will generate a uevent, which indicates to userspace that it should re-probe outputs on this device (to determine modes, etc.).
