// need to be padded to RT CL granularity. On HSW, all tiled
// RT's will have appropriate alignment (given 4KB surface
// base and no mip-map support) and appropriate padding
// (due to tile padding). On BDW+, GMM uses H/VALIGN that

// with certain granularity:
// TileY: 512 Bytes x 128 Lines
// TileX: 1024 Bytes x 64 Lines
// So a CCS must be sized to match that granularity (though
// the RT itself need not be fully padded to that
// granularity to use FastClear).
// (4) Non-MSAA CCS Sizing -- CCS sizing is based on the
// size of the FastClear (with granularity padding) for the
// paired RT. CCS's (byte widths and heights) are scaled
// down from their RT's by:
// TileY: 32 x 32
