43 * a stepping in the range [from, until). The lower stepping bound is
44 * inclusive, the upper bound is exclusive. The most common use-case of this

46 * ("from") at which the hardware issue is first present and another stepping
47 * ("until") at which a hardware fix is present and the software workaround is
48 * no longer necessary. E.g.,
50 * IS_GFX_GT_IP_STEP(gt, IP_VER(12, 70), STEP_A0, STEP_B0)
51 * IS_GFX_GT_IP_STEP(gt, IP_VER(12, 71), STEP_B1, STEP_FOREVER)
53 * "STEP_FOREVER" can be passed as "until" for workarounds that have no upper
54 * stepping bound for the specified IP version.
