From bd3b3004b1d303f2cbb17020bb338c4653b90f76 Mon Sep 17 00:00:00 2001 From: Michel Thierry Date: Tue, 30 Jul 2019 17:49:02 -0700 Subject: [PATCH] drm/i915/tgl: Report valid VDBoxes with SFC capability In Gen11, only even numbered "logical" VDBoxes are hooked up to a SFC (Scaler & Format Converter) unit. This is not the case in Tigerlake, where each VDBox can access a SFC. We will use this information to decide when the SFC units need to be reset and also pass it to the GuC.
