CONFIG_MAX_CPUS : Saves space in the ACPI tables and additional stack space for maximum possible number of cores in the system. Might be better named as CONFIG_MAX_CPUs_CORES (AMD only)
CONFIG_MAX_PHYSICAL_CPUS: Used to set memory SPD addresses and in coherent HyperTransport initialization (AMD only)
CONFIG_LOGICAL_CPUS : This is the flag to build in multi-core support. Similar to CONFIG_MAX_CPUS but only set to 0 or 1. (Used by AMD and Intel code)
Your setup: CONFIG_MAX_CPUS : 4 - 4 cores CONFIG_MAX_PHYSICAL_CPUS: 2 - 2 CPUs CONFIG_LOGICAL_CPUS : 1 - build multi core support in.
I'm not suggesting a change. I'm just trying to make sure I understand the semantics.
So, would it make sense to think of it as having an option that defines the number of cores per CPU (e.g. CONFIG_CORES_PER_CPU) and let CONFIG_MAX_CPUS equal CONFIG_MAX_PHYSICAL_CPUS * CONFIG_CORES_PER_CPU?
