From eceaf7e2340fca0079300692733206b2af555bd9 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 18 May 2017 10:57:42 -0700 Subject: [PATCH] anv: Predicate 48bit support on gen >= 8 This doesn't matter right now since it only affects whether or not we set the kernel bit but, if we ever do anything else based on it, we'll want it to be correct per-gen.
