Subject: drm/i915/gvt: Update force-to-nonpriv register whitelist
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1fd45b09b10f8ea56b14c0cf128c21ad5dd3c496;p=openwrt%2Fstaging%2Fblogic.git

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.
