131 * Cache_Flush sampler message to ensure that the L1 cache remains

136 * Whenever the value of the Dynamic_State_Base_Addr,
137 * Surface_State_Base_Addr are altered, the L1 state cache must be
138 * invalidated to ensure the new surface or sampler state is fetched
139 * from system memory.
141 * The PIPE_CONTROL command has a "State Cache Invalidation Enable" bit
142 * which, according the PIPE_CONTROL instruction documentation in the
145 * Setting this bit is independent of any other bit in this packet.
146 * This bit controls the invalidation of the L1 and L2 state caches
147 * at the top of the pipe i.e. at the parsing time.
149 * Unfortunately, experimentation seems to indicate that state cache
150 * invalidation through a PIPE_CONTROL does nothing whatsoever in
151 * regards to surface state and binding tables. In stead, it seems that
152 * invalidating the texture cache is what is actually needed.
154 * XXX: As far as we have been able to determine through
155 * experimentation, shows that flush the texture cache appears to be
156 * sufficient. The theory here is that all of the sampling/rendering
157 * units cache the binding table in the texture cache. However, we have
158 * yet to be able to actually confirm this.
