[Intel-gfx] [PATCH] drm/i915: Retrieve the current mode upon KMS takeover v2
Jesse Barnes
jbarnes at virtuousgeek.org
Fri May 3 19:39:54 CEST 2013
Read the current hardware state to retrieve the active mode and populate
our CRTC config if that mode matches our presumptions.
v2: check that get_hw_state gave us a valid pipe (Imre)
add clock_get for ILK+ (Jesse)
