5.2.18 Corrected Platform Error Polling Table (CPEP)
Platforms may contain the ability to detect and correct certain operational errors while maintaining
platform function. These errors may be logged by the platform for the purpose of retrieval.
Depending on the underlying hardware support, the means for retrieving corrected platform error
information varies. If the platform hardware supports interrupt-based signaling of corrected platform
errors, the MADT Platform Interrupt Source Structure describes the Corrected Platform Error
Interrupt (CPEI). See Section 5.2.12.11,”Platform Interrupt Source Structure”. Alternatively, OSPM
may poll processors for corrected platform error information. Error log information retrieved from a
processor may contain information for all processors within an error reporting group. As such, it
may not be necessary for OSPM to poll all processors in the system to retrieve complete error
information. This optional table provides information that allows OSPM to poll only the processors
necessary for a complete report of the platform’s corrected platform error information.
