config HAVE_ACPI_APEI bool config HAVE_ACPI_APEI_NMI bool config ACPI_APEI bool "ACPI Platform Error Interface (APEI)" select MISC_FILESYSTEMS select PSTORE select UEFI_CPER depends on HAVE_ACPI_APEI help APEI allows to report errors (for example from the chipset) to the operating system. This improves NMI handling especially. In addition it supports error serialization and error injection. config ACPI_APEI_GHES bool "APEI Generic Hardware Error Source" depends on ACPI_APEI select ACPI_HED select IRQ_WORK select GENERIC_ALLOCATOR help Generic Hardware Error Source provides a way to report platform hardware errors (such as that from chipset). It works in so called "Firmware First" mode, that is, hardware errors are reported to firmware firstly, then reported to Linux by firmware. This way, some non-standard hardware error registers or non-standard hardware link can be checked by firmware to produce more valuable hardware error information for Linux. config ACPI_APEI_PCIEAER bool "APEI PCIe AER logging/recovering support" depends on ACPI_APEI && PCIEAER help PCIe AER errors may be reported via APEI firmware first mode. Turn on this option to enable the corresponding support. config ACPI_APEI_SEA bool "APEI Synchronous External Abort logging/recovering support" depends on ARM64 && ACPI_APEI_GHES default y help This option should be enabled if the system supports firmware first handling of SEA (Synchronous External Abort). SEA happens with certain faults of data abort or instruction abort synchronous exceptions on ARMv8 systems. If a system supports firmware first handling of SEA, the platform analyzes and handles hardware error notifications from SEA, and it may then form a HW error record for the OS to parse and handle. This option allows the OS to look for such hardware error record, and take appropriate action. config ACPI_APEI_MEMORY_FAILURE bool "APEI memory error recovering support" depends on ACPI_APEI && MEMORY_FAILURE help Memory errors may be reported via APEI firmware first mode. Turn on this option to enable the memory recovering support. config ACPI_APEI_EINJ tristate "APEI Error INJection (EINJ)" depends on ACPI_APEI && DEBUG_FS help EINJ provides a hardware error injection mechanism, it is mainly used for debugging and testing the other parts of APEI and some other RAS features. config ACPI_APEI_ERST_DEBUG tristate "APEI Error Record Serialization Table (ERST) Debug Support" depends on ACPI_APEI help ERST is a way provided by APEI to save and retrieve hardware error information to and from a persistent store. Enable this if you want to debugging and testing the ERST kernel support and firmware implementation.
