CONFIG_SMP and CONFIG_ACPI are independent. So if you select CONFIG_SMP and don't select CONFIG_ACPI, then your PC will need to support MPS if Linux is going to bring up the processors... There no longer exists a build-time concept of "minimal part of ACPI that is needed" -- you either include CONFIG_ACPI or you exclude it. However, at boot-time, "acpi=ht" is still present -- primarily for some old systems with HT that didn't run ACPI well. No idea if this this is still needed in practice but occasionally acpi=ht comes in handy to debug table related issues. -Len - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
