1config ACPI_APEI 2 bool "ACPI Platform Error Interface (APEI)" 3 select PSTORE 4 depends on X86 5 help 6 APEI allows to report errors (for example from the chipset) 7 to the operating system. This improves NMI handling 8 especially. In addition it supports error serialization and 9 error injection. 10 11config ACPI_APEI_GHES 12 tristate "APEI Generic Hardware Error Source" 13 depends on ACPI_APEI && X86 14 select ACPI_HED 15 help 16 Generic Hardware Error Source provides a way to report 17 platform hardware errors (such as that from chipset). It 18 works in so called "Firmware First" mode, that is, hardware 19 errors are reported to firmware firstly, then reported to 20 Linux by firmware. This way, some non-standard hardware 21 error registers or non-standard hardware link can be checked 22 by firmware to produce more valuable hardware error 23 information for Linux. 24 25config ACPI_APEI_EINJ 26 tristate "APEI Error INJection (EINJ)" 27 depends on ACPI_APEI && DEBUG_FS 28 help 29 EINJ provides a hardware error injection mechanism, it is 30 mainly used for debugging and testing the other parts of 31 APEI and some other RAS features. 32 33config ACPI_APEI_ERST_DEBUG 34 tristate "APEI Error Record Serialization Table (ERST) Debug Support" 35 depends on ACPI_APEI 36 help 37 ERST is a way provided by APEI to save and retrieve hardware 38 error information to and from a persistent store. Enable this 39 if you want to debugging and testing the ERST kernel support 40 and firmware implementation. 41
