From cb2458baf8b55c3bf8afb22360dd2166d4637b9b Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Thu, 18 Oct 2018 13:51:32 +0200 Subject: [PATCH] drm/i915/gen11: Program the chroma upsampler for HDR planes. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We configure the chroma upsampler with the same chroma siting as used by the scaler for consistency, the chroma upsampler is used instead of the scaler for YUV 4:2:0 on ICL's HDR planes.
