This improves NMI handling 17 especially. In addition it supports error serialization and 18 error injection. 19 20config ACPI_APEI_GHES 21 bool "APEI Generic Hardware Error Source" 22 depends on ACPI_APEI 23 select ACPI_HED 24 select IRQ_WORK 25 select GENERIC_ALLOCATOR 26 help 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. 35 36config ACPI_APEI_PCIEAER 37 bool "APEI PCIe AER logging/recovering support" 38 depends on ACPI_APEI && PCIEAER 39 help 40 PCIe AER errors may be reported via APEI firmware first mode. 41 Turn on this option to enable the corresponding support. 42 43config ACPI_APEI_SEA 44 bool "APEI Synchronous External Abort logging/recovering support" 45 depends on ARM64 && ACPI_APEI_GHES 46 default y 47 help 48 This option should be enabled if the system supports 49 firmware first handling of SEA (Synchronous External Abort). 50 SEA happens with certain faults of data abort or instruction 51 abort synchronous exceptions on ARMv8 systems. If a system 52 supports firmware first handling of SEA, the platform analyzes 53 and handles hardware error notifications from SEA, and it may then 54 form a HW error record for the OS to parse and handle. This 55 option allows the OS to look for such hardware error record, and 56 take appropriate action. 57 58config ACPI_APEI_MEMORY_FAILURE 59 bool "APEI memory error recovering support" 60 depends on ACPI_APEI && MEMORY_FAILURE 61 help 62 Memory errors may be reported via APEI firmware first mode. 63 Turn on this option to enable the memory recovering support. 64 65config ACPI_APEI_EINJ 66 tristate "APEI Error INJection (EINJ)" 67 depends on ACPI_APEI && DEBUG_FS 68 help 69 EINJ provides a hardware error injection mechanism, it is 70 mainly used for debugging and testing the other parts of 71 APEI and some other RAS features. 72 73config ACPI_APEI_ERST_DEBUG 74 tristate "APEI Error Record Serialization Table (ERST) Debug Support" 75 depends on ACPI_APEI 76 help 77 ERST is a way provided by APEI to save and retrieve hardware 78 error information to and from a persistent store. Enable this 79 if you want to debugging and testing the ERST kernel support 80 and firmware implementation. 81
