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

153 * Whenever the value of the Dynamic_State_Base_Addr,

155 * invalidated to ensure the new surface or sampler state is fetched
156 * from system memory.
158 * The PIPE_CONTROL command has a "State Cache Invalidation Enable" bit
159 * which, according the PIPE_CONTROL instruction documentation in the
162 * Setting this bit is independent of any other bit in this packet.
163 * This bit controls the invalidation of the L1 and L2 state caches
164 * at the top of the pipe i.e. at the parsing time.
166 * Unfortunately, experimentation seems to indicate that state cache
167 * invalidation through a PIPE_CONTROL does nothing whatsoever in
168 * regards to surface state and binding tables. In stead, it seems that
169 * invalidating the texture cache is what is actually needed.
171 * XXX: As far as we have been able to determine through
172 * experimentation, shows that flush the texture cache appears to be
173 * sufficient. The theory here is that all of the sampling/rendering
174 * units cache the binding table in the texture cache. However, we have
175 * yet to be able to actually confirm this.

1013 * 2) If this transition is into the GENERAL layout and we then use the
1014 * image as a storage image, then we must have the aux buffer in the
1015 * pass-through state so that, if we then go to texture from the
1016 * image, we get the results of our storage image writes and not the
1017 * fast clear color or other random data.
1019 * For CCS both of the problems above are real demonstrable issues. In
1020 * that case, the only thing we can do is to perform an ambiguate to
1021 * transition the aux surface into the pass-through state.
1023 * For MCS, (2) is never an issue because we don't support multisampled
1024 * storage images. In theory, issue (1) is a problem with MCS but we've
1025 * never seen it in the wild. For 4x and 16x, all bit patters could, in
1026 * theory, be interpreted as something but we don't know that all bit
1027 * patterns are actually valid. For 2x and 8x, you could easily end up
1028 * with the MCS referring to an invalid plane because not all bits of
1029 * the MCS value are actually used. Even though we've never seen issues
1030 * in the wild, it's best to play it safe and initialize the MCS. We
1031 * can use a fast-clear for MCS because we only ever touch from render
1032 * and texture (no image load store).
