From b5667627963b51baa06868a550d2bc340e3d18a9 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Wed, 4 Nov 2015 09:05:27 -0800 Subject: [PATCH] drm/i915/bxt: Fix eDP panel fitting (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit BXT CRTC scaling uses the same gen9 codepaths as SKL; these codepaths store panel fitter information in pipe_config->pch_pfit. However since HAS_PCH_SPLIT() is false for BXT we never actually wind up filling in this structure (we wind up filling in pipe_config->gmch_pfit instead, which is ignored when we go to program the hardware). Make sure we always take the PCH code path on gen9+ platforms. v2: Use HAS_GMCH_DISPLAY() to more cleanly describe the platforms that actually want to use GMCH-style panel fitting.
