1199 * 1) Having an invalid value in the buffer can confuse the hardware.
1200 * For instance, with CCS_E on SKL, a two-bit CCS value of 2 is
1201 * invalid and leads to the hardware doing strange things. It
1202 * doesn't hang as far as we can tell but rendering corruption can
1205 * 2) If this transition is into the GENERAL layout and we then use the
1206 * image as a storage image, then we must have the aux buffer in the
1207 * pass-through state so that, if we then go to texture from the
1208 * image, we get the results of our storage image writes and not the
1209 * fast clear color or other random data.
1211 * For CCS both of the problems above are real demonstrable issues. In
1212 * that case, the only thing we can do is to perform an ambiguate to
1213 * transition the aux surface into the pass-through state.
1215 * For MCS, (2) is never an issue because we don't support multisampled
1216 * storage images. In theory, issue (1) is a problem with MCS but we've
1217 * never seen it in the wild. For 4x and 16x, all bit patters could, in
1218 * theory, be interpreted as something but we don't know that all bit
1219 * patterns are actually valid. For 2x and 8x, you could easily end up
1220 * with the MCS referring to an invalid plane because not all bits of
1221 * the MCS value are actually used. Even though we've never seen issues
1222 * in the wild, it's best to play it safe and initialize the MCS. We
1223 * can use a fast-clear for MCS because we only ever touch from render
1224 * and texture (no image load store).

2014 * globally visible. This type of synchronization is required prior to

2023 * Enable, Depth Cache Flush Enable, DC Flush) in PIPE_CONTROL only
2024 * ensures the write caches are flushed and doesn't guarantee the data

2027 * SW can track the completion of the end-of-pipe-synchronization by
2028 * using "Notify Enable" and "PostSync Operation - Write Immediate

4599 * 2. genX(cmd_buffer_apply_pipe_flushes)() resets the cache tracking to
