From e6e2ac07118b15f25683fcbd59ea1be73ec9465d Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Thu, 24 Oct 2019 12:51:21 -0700 Subject: [PATCH] drm/i915: do not set MOCS control values on dgfx On dgfx there's no LLC and eDRAM control table. Since now this also means the device has global MOCS, just return early on the initialization function. L3 settings still apply and still need to be tweaked.
