704 * DG2 hardware steppings are a bit unusual. The hardware design was forked to
705 * create three variants (G10, G11, and G12) which each have distinct
706 * workaround sets. The G11 and G12 forks of the DG2 design reset the GT
707 * stepping back to "A0" for their first iterations, even though they're more
708 * similar to a G10 B0 stepping and G10 C0 stepping respectively in terms of
709 * functionality and workarounds. However the display stepping does not reset
710 * in the same manner --- a specific stepping like "B0" has a consistent
711 * meaning regardless of whether it belongs to a G10, G11, or G12 DG2.
712 *
713 * TLDR: All GT workarounds and stepping-specific logic must be applied in
714 * relation to a specific subplatform (G10/G11/G12), whereas display workarounds
715 * and stepping-specific logic will be applied with a general DG2-wide stepping
