From e8e7a2b8ccfdae0d4cb6bd25824bbedcd42da316 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 21 Apr 2011 22:18:32 +0100 Subject: drm/i915: restore only the mode of this driver on lastclose (v2) i915 calls the panic handler function on last close to reset the modes, however this is a really bad idea for multi-gpu machines, esp shareable gpus machines. So add a new entry point for the driver to just restore its own fbcon mode. v2: move code into fb helper, fix panic code to block mode change on powered off GPUs.
