drm/i915: Add non claimed mmio checking for vlv/chv Imre mentioned that chv might also have capability to track unclaimed mmio accesses. Ville added that both chv and vlv has this capability and he had already made this way back [1]. Mimic what Ville's patch does but adapt on top of less frequent mmio accesses by omitting checking always on reg writes. This patch is untested as of now. v2: overflow handling and posting omitted (Ville) References: [1] http://lists.freedesktop.org/archives/intel-gfx/2013-May/027599.html Cc: Imre Deak <imre.deak@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1450201542-22918-1-git-send-email-mika.kuoppala@intel.com
