From 248a124d6fc0fde44b8fafc695ca4a2c24eb0856 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 30 Jan 2017 10:44:56 +0000 Subject: [PATCH] drm/i915: Make intel_detect_preproduction_hw easier to extend MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit As we add new generations, we should keep detecting new pre-production system development platforms that were temporarily enabled to facilitate initial development and now superseded by production systems. To make it easier to add more platforms, split the if into a series of logical operations. v2: s/sdv/pre/ - not all system development vehicles are for preproduction usage.
