drm/i915/gvt: Parse default state to update reg whitelist
Rather than break existing context objects by incorrectly forcing them to rogue cache coherency and trying to assert a new mapping, read the reg whitelist from the default context image. And use gvt->gt, never &dev_priv->gt. Fixes: 493f30cd ("drm/i915/gvt: parse init context to update cmd accessible reg whitelist") Acked-by:Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by:
