From: Ville Syrjälä Date: Thu, 19 Mar 2015 19:18:57 +0000 (+0200) Subject: drm/i915: Eliminate the RMW sprite colorkey management X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=47ecbb208bf44be0e798495d08837fe7c4138201;p=linux-beck.git drm/i915: Eliminate the RMW sprite colorkey management Store the colorkey in intel_plane and kill off all the RMW stuff handling it. This is just an intermediate step and eventually the colorkey needs to be converted into some properties. v2: Actually update the hardware state in the set_colorkey ioctl (Daniel) Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_drv.h b/drivers/gpu/drm/i915/intel_drv.h index c06854df466d..6f20f3a01398 100644 --- a/drivers/gpu/drm/i915/intel_drv.h +++ b/drivers/gpu/drm/i915/intel_drv.h @@ -510,6 +510,9 @@ struct intel_plane { bool can_scale;
