This improves NMI handling 16 especially. In addition it supports error serialization and 17 error injection. 18 19config ACPI_APEI_GHES 20 bool "APEI Generic Hardware Error Source" 21 depends on ACPI_APEI 22 select ACPI_HED 23 select IRQ_WORK 24 select GENERIC_ALLOCATOR 25 help 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. 34 35config ACPI_APEI_PCIEAER 36 bool "APEI PCIe AER logging/recovering support" 37 depends on ACPI_APEI && PCIEAER 38 help 39 PCIe AER errors may be reported via APEI firmware first mode. 40 Turn on this option to enable the corresponding support. 41 42config ACPI_APEI_SEA 43 bool "APEI Synchronous External Abort logging/recovering support" 44 depends on ARM64 && ACPI_APEI_GHES 45 default y 46 help 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. 56 57config ACPI_APEI_MEMORY_FAILURE 58 bool "APEI memory error recovering support" 59 depends on ACPI_APEI && MEMORY_FAILURE 60 help 61 Memory errors may be reported via APEI firmware first mode. 62 Turn on this option to enable the memory recovering support. 63 64config ACPI_APEI_EINJ 65 tristate "APEI Error INJection (EINJ)" 66 depends on ACPI_APEI && DEBUG_FS 67 help 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. 71 72config ACPI_APEI_ERST_DEBUG 73 tristate "APEI Error Record Serialization Table (ERST) Debug Support" 74 depends on ACPI_APEI 75 help 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. 80
