    *
    *    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

    *
    *    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.

       *
       *  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

       * that case, the only thing we can do is to perform an ambiguate to
       * transition the aux surface into the pass-through state.

       * never seen it in the wild.  For 4x and 16x, all bit patterns could,

       * 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
       * could use a fast-clear for MCS because we only ever touch from render

 *    considered invalid; the indirect pointers are not saved in the context.
 *    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.
