From 4d4dead67a4ab1d5de393f15ed5e4e2aa63d3bcf Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Sun, 3 Nov 2013 16:47:33 -0800 Subject: drm/i915/bdw: Add device IDs v2: Squash in "drm/i915/bdw: Add BDW to the HAS_DDI check" as suggested by Damien. v3: Squash in VEBOX enabling from Zhao Yakui v4: Rebase on top of Jesse's patch to extract all pci ids to include/drm/i915_pciids.h. v4: Replace Halo by its marketing moniker Iris. Requested by Ben. v5: Switch from info->has*ring to info->ring_mask. v6: Add 0x16X2 variant (which is newer than this patch) Rename to use new naming scheme (Chris) Remove Simulator PCI ids. These snuck in during rebase (Chris) v7: Fix poor sed job from v6 Make the desktop variants use the desktop macro (Rebase error). Notice that this makes no functional difference - it's just confusing.
