Why is that? The T1 cores are repesented as SMT units. On multi-chip T2 systems such as 5140 et al., we use MC to repesent the physical CPU chips. So the hierarchy is MC --> SMT See arch/sparc/kernel/smp_64.c:smp_fill_in_sib_core_maps() and it's callers, which scan the hierarchy (using either the OpenFirmware device tree or the sun4v Machine Description). -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
