1142 * 1) Having an invalid value in the buffer can confuse the hardware.
1143 * For instance, with CCS_E on SKL, a two-bit CCS value of 2 is
1144 * invalid and leads to the hardware doing strange things. It
1145 * doesn't hang as far as we can tell but rendering corruption can
1148 * 2) If this transition is into the GENERAL layout and we then use the
1149 * image as a storage image, then we must have the aux buffer in the
1150 * pass-through state so that, if we then go to texture from the
1151 * image, we get the results of our storage image writes and not the
1152 * fast clear color or other random data.
1154 * For CCS both of the problems above are real demonstrable issues. In
1155 * that case, the only thing we can do is to perform an ambiguate to
1156 * transition the aux surface into the pass-through state.
1158 * For MCS, (2) is never an issue because we don't support multisampled
1159 * storage images. In theory, issue (1) is a problem with MCS but we've
1160 * never seen it in the wild. For 4x and 16x, all bit patters could, in
1161 * theory, be interpreted as something but we don't know that all bit
1162 * patterns are actually valid. For 2x and 8x, you could easily end up
1163 * with the MCS referring to an invalid plane because not all bits of
1164 * the MCS value are actually used. Even though we've never seen issues
1165 * in the wild, it's best to play it safe and initialize the MCS. We
1166 * can use a fast-clear for MCS because we only ever touch from render
1167 * and texture (no image load store).
