112 * invalidated to ensure the new surface or sampler state is fetched
113 * from system memory.
115 * The PIPE_CONTROL command has a "State Cache Invalidation Enable" bit
116 * which, according the PIPE_CONTROL instruction documentation in the
119 * Setting this bit is independent of any other bit in this packet.
120 * This bit controls the invalidation of the L1 and L2 state caches
121 * at the top of the pipe i.e. at the parsing time.
123 * Unfortunately, experimentation seems to indicate that state cache
124 * invalidation through a PIPE_CONTROL does nothing whatsoever in
125 * regards to surface state and binding tables. In stead, it seems that
126 * invalidating the texture cache is what is actually needed.
128 * XXX: As far as we have been able to determine through
129 * experimentation, shows that flush the texture cache appears to be
130 * sufficient. The theory here is that all of the sampling/rendering
131 * units cache the binding table in the texture cache. However, we have
132 * yet to be able to actually confirm this.
