- * ID of hotplugged CPUs[1]. This means that FW_CFG_MAX_CPUS is not the
- * "maximum number of CPUs", but the "limit to the APIC ID values SeaBIOS
- * may see".
- *
- * So, this means we must not use max_cpus, here, but the maximum possible
- * APIC ID value, plus one.
+ * For machine types prior to 1.8, SeaBIOS needs FW_CFG_MAX_CPUS for
+ * building MPTable, ACPI MADT, ACPI CPU hotplug and ACPI SRAT table,
+ * that tables are based on xAPIC ID and QEMU<->SeaBIOS interface
+ * for CPU hotplug also uses APIC ID and not "CPU index".
+ * This means that FW_CFG_MAX_CPUS is not the "maximum number of CPUs",
+ * but the "limit to the APIC ID values SeaBIOS may see".
*
- * [1] The only kind of "CPU identifier" used between SeaBIOS and QEMU is
- * the APIC ID, not the "CPU index"
+ * So for compatibility reasons with old BIOSes we are stuck with
+ * "etc/max-cpus" actually being apic_id_limit
