The @file comments in UefiCpuPkg/CpuS3DataDxe say, [...] It also only supports the number of CPUs reported by the MP Services Protocol, so this module does not support hot plug CPUs. This module can be copied into a CPU specific package and customized if these additional features are required. [...]
The driver is so small that the simplest way to extend it with hotplug support is indeed to clone it at first. In this patch, customize the driver only with the following no-op steps: - Update copyright notices. - Update INF_VERSION to the latest INF spec version (1.29). - Update FILE_GUID. - Drop the UNI files. - Replace EFI_D_VERBOSE with DEBUG_VERBOSE, to appease "PatchCheck.py".
