Ville Syrjälä 6e1b4fdad5 drm/i915: Delay disabling of VGA memory until vgacon->fbcon handoff is done ... When transitioning away from vgacon the system tries to save the current contents of the VGA memory, so that it can be cleanly handed off to fbcon (or whatever comes afterwards). The recent change commit 81b5c7bc8d Author: Alex Williamson <alex.williamson@redhat.com> Date: Wed Aug 28 09:39:08 2013 -0600 i915: Update VGA arbiter support for newer devices caused i915 to disable VGA memory decode for the IGD when i915 is initializing. Unfortunately that happens before the vgacon->fbcon handoff so vgacon_save_screen() will read out all ones from the VGA memory. After the handoff fbcon will inherit the bogus state from vgacon, and pre-fills the fb with matching contents. The end result is a white rectangle in the top left corner of the screen, the size of which matches the now inactive VGA console. To remedy the situation delay the disabling of VGA memory until the vgacon->fbcon handoff has happened. Also rename i915_enable_vga to i915_enable_vga_mem to make the relationship between these functions clearer.
