-   /* After re-setting the surface state base address, we have to do some
-    * cache flusing so that the sampler engine will pick up the new
-    * SURFACE_STATE objects and binding tables. From the Broadwell PRM,
-    * Shared Function > 3D Sampler > State > State Caching (page 96):
-    *
-    *    Coherency with system memory in the state cache, like the texture
-    *    cache is handled partially by software. It is expected that the
-    *    command stream or shader will issue Cache Flush operation or
-    *    Cache_Flush sampler message to ensure that the L1 cache remains
-    *    coherent with system memory.
-    *
-    *    [...]
-    *
-    *    Whenever the value of the Dynamic_State_Base_Addr,
-    *    Surface_State_Base_Addr are altered, the L1 state cache must be
-    *    invalidated to ensure the new surface or sampler state is fetched
-    *    from system memory.
-    *
-    * The PIPE_CONTROL command has a "State Cache Invalidation Enable" bit
-    * which, according the PIPE_CONTROL instruction documentation in the
-    * Broadwell PRM:
-    *
-    *    Setting this bit is independent of any other bit in this packet.
-    *    This bit controls the invalidation of the L1 and L2 state caches
-    *    at the top of the pipe i.e. at the parsing time.
-    *
-    * Unfortunately, experimentation seems to indicate that state cache
-    * invalidation through a PIPE_CONTROL does nothing whatsoever in
-    * regards to surface state and binding tables.  In stead, it seems that
-    * invalidating the texture cache is what is actually needed.
-    *
-    * XXX:  As far as we have been able to determine through
-    * experimentation, shows that flush the texture cache appears to be
-    * sufficient.  The theory here is that all of the sampling/rendering
-    * units cache the binding table in the texture cache.  However, we have
-    * yet to be able to actually confirm this.
