From: Daniel Vetter Date: Wed, 8 Sep 2010 19:18:53 +0000 (+0200) Subject: intel-gtt: introduce intel_gtt_driver X-Git-Tag: firefly_0821_release~7613^2~3600^2~31^2~182 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1a997ff2a0089a07a5494545d31f4366742dea43;p=firefly-linux-kernel-4.4.55.git intel-gtt: introduce intel_gtt_driver Same idea as INTEL_INFO from drm/i915. This - reduces the dependancy on agp_driver - stops the what-does-IS_I965G-mean confusion (here it's just gen4, in drm/i915 it's gen >=4) - further prepares the separation of the fake agp driver from the rest.
