From 1fd45b09b10f8ea56b14c0cf128c21ad5dd3c496 Mon Sep 17 00:00:00 2001 From: Colin Xu Date: Wed, 22 May 2019 14:20:18 +0800 Subject: [PATCH] drm/i915/gvt: Update force-to-nonpriv register whitelist Host prints below warning message when guest running some application: "gvt: vgpu(1) Invalid FORCE_NONPRIV write 2754 at 24f0". "gvt: vgpu(1) Invalid FORCE_NONPRIV write 28a0 at 24f0". Registers 0x2754 and 0x28a0 are required by guest so add to whitelist.
