From 413f3c19f8ecefd29067897db9c414a29d86685f Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Tue, 6 Jun 2017 13:30:30 -0700 Subject: [PATCH] drm/i915/cnl: Introduce Cannonlake platform defition. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cannonlake is a Intel® Processor containing Intel® HD Graphics following Kabylake. It is Gen10. Let's start by adding the platform definition based on previous platforms but yet as alpha_support. On following patches we will start adding PCI IDs and the platform specific changes. CNL has an increased DDB size as Damien had previously noticed and provided a separated patch that got squashed here. v2: Squash DDB size here per Ander request.
