9 bool "ACPI Platform Error Interface (APEI)"
10 select MISC_FILESYSTEMS
13 depends on HAVE_ACPI_APEI
15 APEI allows to report errors (for example from the chipset)
16 to the operating system. This improves NMI handling
17 especially. In addition it supports error serialization and
21 bool "APEI Generic Hardware Error Source"
25 select GENERIC_ALLOCATOR
27 Generic Hardware Error Source provides a way to report
28 platform hardware errors (such as that from chipset). It
29 works in so called "Firmware First" mode, that is, hardware
30 errors are reported to firmware firstly, then reported to
31 Linux by firmware. This way, some non-standard hardware
32 error registers or non-standard hardware link can be checked
33 by firmware to produce more valuable hardware error
34 information for Linux.

37 bool "APEI PCIe AER logging/recovering support"
38 depends on ACPI_APEI && PCIEAER
40 PCIe AER errors may be reported via APEI firmware first mode.
41 Turn on this option to enable the corresponding support.

49 bool "APEI memory error recovering support"
50 depends on ACPI_APEI && MEMORY_FAILURE

57 depends on ACPI_APEI && DEBUG_FS
59 EINJ provides a hardware error injection mechanism, it is
60 mainly used for debugging and testing the other parts of
61 APEI and some other RAS features.

64 tristate "APEI Error Record Serialization Table (ERST) Debug Support"
67 ERST is a way provided by APEI to save and retrieve hardware
68 error information to and from a persistent store. Enable this
69 if you want to debugging and testing the ERST kernel support
70 and firmware implementation.
