| |
X86 Generic Architecture (X86_GENERICARCH) includes support for Summit architecture. Enabling X86_GENERICARCH, SMP and HIGHMEM64G allows NUMA to be selected but that configuration will not build because it requires ACPI for the Summit NUMA support.
Fix: require ACPI for NUMA support with X86_GENERICARCH
update the menu comment noting this
set default NR_CPUS to 32 for GENERICARCH (since it includes BIGSMP and SUMMIT which default to 32)
