Soon we will receive a 2-CPU mainboard with 2 Quad-Core Xeons on it. We have also a GNU system with Linux kernel (preconfigured). Currently, this Linux runs on a multi-core 1-CPU (Quad Core).
My question is if I will disable in BIOS one of the Xeons, will current Linux run on only one CPU? Will I need to change Linux configuration settings?
Here is important config settings:
CONFIG_NUMA=y CONFIG_K8_NUMA=y CONFIG_X86_64_ACPI_NUMA=y CONFIG_NUMA_EMU=y CONFIG_ACPI_NUMA=y # CONFIG_X86_VSMP is not set CONFIG_SMP=y CONFIG_SUSPEND_SMP=y
