 * During driver startup, we initialize the steering control register to
 * direct reads to a slice/subslice that are valid for the 'subslice' class
 * of multicast registers.  If another type of steering does not have any

 * need to explicitly re-steer reads of registers of the other type.

/**
 * struct xe_gt - A "Graphics Technology" unit of the GPU
 *
 * A GT ("Graphics Technology") is the subset of a GPU primarily responsible
 * for implementing the graphics, compute, and/or media IP.  It encapsulates
 * the hardware engines, programmable execution units, and GuC.   Each GT has
 * its own handling of power management (RC6+forcewake) and multicast register
 * steering.
 *
 * A GPU/tile may have a single GT that supplies all graphics, compute, and
 * media functionality, or the graphics/compute and media may be split into
 * separate GTs within a tile.
