/* After re-setting the surface state base address, we have to do some

* 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.
