+ * 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

- *
- * 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.
