Gets detailed MP-related information on the requested processor at the
instant this call is made. This service may only be called from the BSP.
This service retrieves detailed MP-related information about any processor
on the platform. Note the following:
- The processor information may change during the course of a boot session.
- The information presented here is entirely MP related.
Information regarding the number of caches and their sizes, frequency of operation,
slot numbers is all considered platform-related information and is not provided
by this service.
@param[in] This A pointer to the EFI_MP_SERVICES_PROTOCOL
instance.
@param[in] ProcessorNumber The handle number of processor.
@param[out] ProcessorInfoBuffer A pointer to the buffer where information for
the requested processor is deposited.
@retval EFI_SUCCESS Processor information was returned.
@retval EFI_DEVICE_ERROR The calling processor is an AP.
@retval EFI_INVALID_PARAMETER ProcessorInfoBuffer is NULL.
@retval EFI_NOT_FOUND The processor with the handle specified by
ProcessorNumber does not exist in the platform.
