** Description changed: EDAC_GHES is essential for ARMv8.0 Server systems, as it enables firmware-first error handling of memory and CPU errors. Due to a lack of standard RAS architecture (or machine check architecture equivalent) on ARMv8.0 systems, APEI/GHES is the only mechanism available for reporting hardware errors (e.g. memory and CPU errors). This enables reporting of hardware errors, and also helps enable memory fault recovery mechanisms to extend the life of the system by offlining pages when recoverable uncorrected errors are encountered. Note that other ARM vendors will be going in this direction for hardware error handling. - Currently EDAC_MM_EDAC=m is in Ubuntu, but EDAC_GHES requires this to be - =y therefore it is not selected. + Currently ACPI_APEI_GHES=n is in Ubuntu, but EDAC_GHES requires this to + be =y therefore it is not selected.
