EFI_COMPUTING_UNIT_CPU_DISABLED_ERROR_DATA Struct Reference


Data Fields

EFI_STATUS_CODE_DATA DataHeader
UINT32 Cause
BOOLEAN SoftwareDisabled

Detailed Description

This structure provides information about the disabled computing unit.

This structure provides details as to why and how the computing unit was disabled. The causes should cover the typical reasons a processor would be disabled. How the processor was disabled is important because there are distinct differences between hardware and software disabling.


Field Documentation

The reason for disabling the processor.

The data header identifying the data. DataHeader.HeaderSize should be sizeof (EFI_STATUS_CODE_DATA), DataHeader.Size should be sizeof (EFI_COMPUTING_UNIT_CPU_DISABLED_ERROR_DATA) - HeaderSize, and DataHeader.Type should be EFI_STATUS_CODE_SPECIFIC_DATA_GUID.

TRUE if the processor is disabled via software means such as not listing it in the ACPI tables. Such a processor will respond to Interprocessor Interrupts (IPIs). FALSE if the processor is hardware disabled, which means it is invisible to software and will not respond to IPIs.
