4 config HAVE_ACPI_APEI_NMI
8 bool "ACPI Platform Error Interface (APEI)"
9 select MISC_FILESYSTEMS
12 depends on HAVE_ACPI_APEI
14 APEI allows to report errors (for example from the chipset)
15 to the operating system. This improves NMI handling
16 especially. In addition it supports error serialization and
20 bool "APEI Generic Hardware Error Source"
24 select GENERIC_ALLOCATOR
26 Generic Hardware Error Source provides a way to report
27 platform hardware errors (such as that from chipset). It
28 works in so called "Firmware First" mode, that is, hardware
29 errors are reported to firmware firstly, then reported to
30 Linux by firmware. This way, some non-standard hardware
31 error registers or non-standard hardware link can be checked
32 by firmware to produce more valuable hardware error
33 information for Linux.
35 config ACPI_APEI_PCIEAER
36 bool "APEI PCIe AER logging/recovering support"
37 depends on ACPI_APEI && PCIEAER
39 PCIe AER errors may be reported via APEI firmware first mode.
40 Turn on this option to enable the corresponding support.
43 bool "APEI Synchronous External Abort logging/recovering support"
44 depends on ARM64 && ACPI_APEI_GHES
47 This option should be enabled if the system supports
48 firmware first handling of SEA (Synchronous External Abort).
49 SEA happens with certain faults of data abort or instruction
50 abort synchronous exceptions on ARMv8 systems. If a system
51 supports firmware first handling of SEA, the platform analyzes
52 and handles hardware error notifications from SEA, and it may then
53 form a HW error record for the OS to parse and handle. This
54 option allows the OS to look for such hardware error record, and
55 take appropriate action.
57 config ACPI_APEI_MEMORY_FAILURE
58 bool "APEI memory error recovering support"
59 depends on ACPI_APEI && MEMORY_FAILURE
61 Memory errors may be reported via APEI firmware first mode.
62 Turn on this option to enable the memory recovering support.
65 tristate "APEI Error INJection (EINJ)"
66 depends on ACPI_APEI && DEBUG_FS
68 EINJ provides a hardware error injection mechanism, it is
69 mainly used for debugging and testing the other parts of
70 APEI and some other RAS features.
72 config ACPI_APEI_ERST_DEBUG
73 tristate "APEI Error Record Serialization Table (ERST) Debug Support"
76 ERST is a way provided by APEI to save and retrieve hardware
77 error information to and from a persistent store. Enable this
78 if you want to debugging and testing the ERST kernel support
79 and firmware implementation.
