OvmfPkg: clone CpuS3DataDxe from UefiCpuPkg
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".

ACPI CPU Data initialization module
|
||||||
|
|
||||||
|
This module initializes the ACPI_CPU_DATA structure and registers the address
|
||||||
|
of this structure in the PcdCpuS3DataAddress PCD. This is a generic/simple
|
||||||
|
version of this module. It does not provide a machine check handler or CPU
|
||||||
|
register initialization tables for ACPI S3 resume. 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.
