1197 * 1) Having an invalid value in the buffer can confuse the hardware.
1198 * For instance, with CCS_E on SKL, a two-bit CCS value of 2 is
1199 * invalid and leads to the hardware doing strange things. It
1200 * doesn't hang as far as we can tell but rendering corruption can
1203 * 2) If this transition is into the GENERAL layout and we then use the
1204 * image as a storage image, then we must have the aux buffer in the
1205 * pass-through state so that, if we then go to texture from the
1206 * image, we get the results of our storage image writes and not the
1207 * fast clear color or other random data.
1209 * For CCS both of the problems above are real demonstrable issues. In
1210 * that case, the only thing we can do is to perform an ambiguate to
1211 * transition the aux surface into the pass-through state.
1213 * For MCS, (2) is never an issue because we don't support multisampled
1214 * storage images. In theory, issue (1) is a problem with MCS but we've
1215 * never seen it in the wild. For 4x and 16x, all bit patters could, in
1216 * theory, be interpreted as something but we don't know that all bit
1217 * patterns are actually valid. For 2x and 8x, you could easily end up
1218 * with the MCS referring to an invalid plane because not all bits of
1219 * the MCS value are actually used. Even though we've never seen issues
1220 * in the wild, it's best to play it safe and initialize the MCS. We
1221 * can use a fast-clear for MCS because we only ever touch from render
1222 * and texture (no image load store).

2006 * synchronization that requires that the render cache and/or depth
2007 * related caches are flushed to memory, where the data will become
2008 * globally visible. This type of synchronization is required prior to
2009 * SW (CPU) actually reading the result data from memory, or initiating
2010 * an operation that will use as a read surface (such as a texture
2011 * surface) a previous render target and/or depth/stencil buffer
2014 * From Haswell PRM, volume 2, part 1, "End-of-Pipe Synchronization":
2016 * Exercising the write cache flush bits (Render Target Cache Flush
2017 * Enable, Depth Cache Flush Enable, DC Flush) in PIPE_CONTROL only
2018 * ensures the write caches are flushed and doesn't guarantee the data
2019 * is globally visible.
2021 * SW can track the completion of the end-of-pipe-synchronization by
2022 * using "Notify Enable" and "PostSync Operation - Write Immediate
2023 * Data" in the PIPE_CONTROL command.
2025 * In other words, flushes are pipelined while invalidations are handled
2026 * immediately. Therefore, if we're flushing anything then we need to
2027 * schedule an end-of-pipe sync before any invalidations can happen.

4562 * This is implemented by carefully tracking all vertex and index buffer

4569 * the cache to have a too-large range on the next draw call, a pipeline
4570 * stall and VF cache invalidate are added to pending_pipeline_bits.
4572 * 2. genX(cmd_buffer_apply_pipe_flushes)() resets the cache tracking to
4573 * empty whenever we emit a VF invalidate.
4575 * 3. genX(cmd_buffer_update_dirty_vbs_for_gen8_vb_flush)() must be called
4576 * after every 3DPRIMITIVE and copies the bound range into the dirty
4577 * range for each used buffer. This has to be a separate step because
