18.3.2.6 Generic Hardware Error Source
The platform may describe a generic hardware error source to OSPM using the Generic Hardware
Error Source structure. A generic hardware error source is an error source that either notifies OSPM
of the presence of an error using a non-standard notification mechanism or reports error information
that is encoded in a non-standard format.
Using the information in a Generic Hardware Error Source structure, OSPM configures an error
handler to read the error data from an error status block – a range of memory set aside by the
platform for recording error status information.
As the generic hardware error source is non-standard, OSPM does not implement built-in support for
configuration and control operations. The error source must be configured by system firmware
during boot.

Description
Type 2 0 9 – Generic Hardware Error Source Structure.
Source Id 2 2 Uniquely identify the error source.
Related Source Id 2 4 If this generic error source represents an alternate source to a
separate source that the platform has specified that it requires
firmware-first handling (See Section 18.4,”Firmware First Error
Handling”), this field identifies the error source for which this
error source is the alternate.
If this generic error source does not represent an alternate
source, this field must be set to 0xFFFF.
Flags 1 6 Reserved.
Enabled 1 7 If the field value is 1, indicates this error source is to be enabled.
If the field value is 0, indicates that the error source is not to be
enabled.

4 12 Indicates the maximum number of error sections included in an
error record created as a result of an error reported by this error
source. Must be >= 1.
