From: Ville Syrjälä Date: Thu, 14 Jan 2016 12:53:35 +0000 (+0200) Subject: drm/i915: Use the active wm config for merging on ILK-BDW X-Git-Tag: v5.15~13965^2~42^2~32 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=d890565c44447db08fd9d07f5b02928a07a88c7e;p=mirror_ubuntu-kernels.git drm/i915: Use the active wm config for merging on ILK-BDW ilk_program_watermarks() is supposed to merge the active watermarks from all pipes. Thus we need to use the active config too instead of some precomputed stuff.
