/**
 * For color images that have an auxiliary surface, request allocation for an
 * additional buffer that mainly stores fast-clear values. Use of this buffer
 * allows us to access the image's subresources while being aware of their
 * fast-clear values in non-trivial cases (e.g., outside of a render pass in
 * which a fast clear has occurred).
 *
 * In order to avoid having multiple clear colors for a single plane of an
 * image (hence a single RENDER_SURFACE_STATE), we only allow fast-clears on
 * the first slice (level 0, layer 0).  At the time of our testing (Jan 17,
 * 2018), there were no known applications which would benefit from fast-
 * clearing more than just the first slice.
 *
 * The fast clear portion of the image is laid out in the following order:
 *
 *  * 1 or 4 dwords (depending on hardware generation) for the clear color
 *  * 1 dword for the anv_fast_clear_type of the clear color
 *  * On gfx9+, 1 dword per level and layer of the image (3D levels count
 *    multiple layers) in level-major order for compression state.
 *
 * For the purpose of discoverability, the algorithm used to manage
 * compression and fast-clears is described here:
 *
 *  * On a transition from UNDEFINED or PREINITIALIZED to a defined layout,
 *    all of the values in the fast clear portion of the image are initialized
 *    to default values.
 *
 *  * On fast-clear, the clear value is written into surface state and also
 *    into the buffer and the fast clear type is set appropriately.  Both
 *    setting the fast-clear value in the buffer and setting the fast-clear
 *    type happen from the GPU using MI commands.
 *
 *  * Whenever a render or blorp operation is performed with CCS_E, we call
 *    genX(cmd_buffer_mark_image_written) to set the compression state to
 *    true (which is represented by UINT32_MAX).
 *
 *  * On pipeline barrier transitions, the worst-case transition is computed
 *    from the image layouts.  The command streamer inspects the fast clear
 *    type and compression state dwords and constructs a predicate.  The
 *    worst-case resolve is performed with the given predicate and the fast
 *    clear and compression state is set accordingly.
 *
 * See anv_layout_to_aux_usage and anv_layout_to_fast_clear_type functions for
 * details on exactly what is allowed in what layouts.
 *
 * On gfx7-9, we do not have a concept of indirect clear colors in hardware.
 * In order to deal with this, we have to do some clear color management.
 *
 *  * For LOAD_OP_LOAD at the top of a renderpass, we have to copy the clear
 *    value from the buffer into the surface state with MI commands.
 *
 *  * For any blorp operations, we pass the address to the clear value into
 *    blorp and it knows to copy the clear color.
