From d308bb082d429eb25dfd2844bcbafe722660a1ff Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 29 Jun 2016 08:28:58 +0100 Subject: lib: Start weaning off defunct intel_chipset.h Several years ago we made the plan of only having one canonical source for i915_pciids.h, the kernel and everyone importing their definitions from that. For consistency, we style the intel_device_info after the kernel, most notably using a generation mask and a per-codename bitfield. This first step converts looking up the generation for a devid tree from a massive if(devid)-chain to a (cached) table lookup.
