From: Ville Syrjälä Date: Thu, 9 Mar 2017 15:44:32 +0000 (+0200) Subject: drm/i915: Organize plane register writes into tighter bunches X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=78587de299dd653d64c731e40f17050cb66d0c27;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Organize plane register writes into tighter bunches Pull all the plane register writes closer together to avoid having a lot of unrelated stuff in between them. This will make things more clear once we'll grab the uncore lock around the entire bunch. Also in the future we might even consider moving more of the register value computation out from the plane update hooks. This should make that easier to do.
