/* After re-setting the surface state base address, we have to do some

*
* 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.

* doesn't hang as far as we can tell but rendering corruption can
* occur.
*
* 2) If this transition is into the GENERAL layout and we then use the
* image as a storage image, then we must have the aux buffer in the
* pass-through state so that, if we then go to texture from the
* image, we get the results of our storage image writes and not the
* fast clear color or other random data.
*
* For CCS both of the problems above are real demonstrable issues. In
* that case, the only thing we can do is to perform an ambiguate to
* transition the aux surface into the pass-through state.
*
* For MCS, (2) is never an issue because we don't support multisampled
* storage images. In theory, issue (1) is a problem with MCS but we've
* never seen it in the wild. For 4x and 16x, all bit patters could, in
* theory, be interpreted as something but we don't know that all bit
* patterns are actually valid. For 2x and 8x, you could easily end up
* with the MCS referring to an invalid plane because not all bits of
* the MCS value are actually used. Even though we've never seen issues
* in the wild, it's best to play it safe and initialize the MCS. We
* can use a fast-clear for MCS because we only ever touch from render

* If any new indirect state commands are executed in the command stream
* while the pipe control is pending, the new indirect state commands are
* preserved.
*
* [DevIVB+]: Using Invalidate State Pointer (ISP) only inhibits context
* restoring of Push Constant (3DSTATE_CONSTANT_*) commands. Push Constant
* commands are only considered as Indirect State Pointers. Once ISP is
* issued in a context, SW must initialize by programming push constant
* commands for all the shaders (at least to zero length) before attempting
* any rendering operation for the same context."
*
* 3DSTATE_CONSTANT_* packets are restored during a context restore,
* even though they point to a BO that has been already unreferenced at
* the end of the previous batch buffer. This has been fine so far since
* we are protected by these scratch page (every address not covered by
* a BO should be pointing to the scratch page). But on CNL, it is
* causing a GPU hang during context restore at the 3DSTATE_CONSTANT_*
* instruction.
*
* The flag "Indirect State Pointers Disable" in PIPE_CONTROL tells the
* hardware to ignore previous 3DSTATE_CONSTANT_* packets during a
* context restore, so the mentioned hang doesn't happen. However,
* software must program push constant commands for all stages prior to
* rendering anything. So we flag them dirty in BeginCommandBuffer.
*
* Finally, we also make sure to stall at pixel scoreboard to make sure the
* constants have been loaded into the EUs prior to disable the push constants
* so that it doesn't hang a previous 3DPRIMITIVE.
