config HAVE_ACPI_APEI

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.
