Advanced Configuration and Power Interface Specification
Data Length 4 12 Length in bytes of the generic error data.
Error Severity 4 16 Identifies the error severity of the reported error:
0 – Recoverable
1 – Fatal
2 – Corrected
3 – None
Note: This is the error severity of the entire event. Each Generic
Error Data Entry also includes its own Error Severity field.

20 The information contained in this field is a collection of zero or
more Generic Error Data Entries (see Table 18-331).
One or more Generic Error Data Entry structures may be recorded in the Generic Error Data
Entries field of the Generic Error Status Block structure. This allows the platform to accumulate
information for multiple hardware components related to a given error event. For example, if the
generic error source represents an error that occurs on a device on the secondary side of a PCI
Express / PCI-X Bridge, it is useful to record error information from the PCI Express Bridge and
from the PCI-X device. Utilizing two Generic Error Data Entry structures enables this. Table 18-
331 defines the layout of a Generic Error Data Entry.
For details of some of the fields defined in Table 18-331. See also Table 3 in section N2.2 of
Appendix N of the UEFI 2.1 specification.

Description
Section Type 16 0 Identifies the type of error data in this entry.
See the Section Type field of the Section Descriptor in the UEFI
2.1 specification.
Error Severity 4 16 Identifies the severity of the reported error.
0 – Recoverable
1 – Fatal
2 – Corrected
3 – None
Revision 2 20 The revision number of the error data. The revision number is
0x0201.
See the Revision field of the Section Descriptor in the UEFI 2.1
specification.
Validation Bits 1 22 Identifies whether certain fields are populated with valid data.
See the Validation Bits field of the Section Descriptor in the UEFI
2.1 specification.
Flags 1 23 Flags describing the error data.
See the Flags field of the Section Descriptor in the UEFI 2.1
specification.
Error Data Length 4 24 Length in bytes of the generic error data. It is valid to have a Data
Length of zero. This would be used for instance in firmware-first
error handling where the platform reports errors to the OSPM
using NMI.
