This improves NMI handling 178c2ecf20Sopenharmony_ci especially. In addition it supports error serialization and 188c2ecf20Sopenharmony_ci error injection. 198c2ecf20Sopenharmony_ci 208c2ecf20Sopenharmony_ciconfig ACPI_APEI_GHES 218c2ecf20Sopenharmony_ci bool "APEI Generic Hardware Error Source" 228c2ecf20Sopenharmony_ci depends on ACPI_APEI 238c2ecf20Sopenharmony_ci select ACPI_HED 248c2ecf20Sopenharmony_ci select IRQ_WORK 258c2ecf20Sopenharmony_ci select GENERIC_ALLOCATOR 268c2ecf20Sopenharmony_ci help 278c2ecf20Sopenharmony_ci Generic Hardware Error Source provides a way to report 288c2ecf20Sopenharmony_ci platform hardware errors (such as that from chipset). It 298c2ecf20Sopenharmony_ci works in so called "Firmware First" mode, that is, hardware 308c2ecf20Sopenharmony_ci errors are reported to firmware firstly, then reported to 318c2ecf20Sopenharmony_ci Linux by firmware. This way, some non-standard hardware 328c2ecf20Sopenharmony_ci error registers or non-standard hardware link can be checked 338c2ecf20Sopenharmony_ci by firmware to produce more valuable hardware error 348c2ecf20Sopenharmony_ci information for Linux. 358c2ecf20Sopenharmony_ci 368c2ecf20Sopenharmony_ciconfig ACPI_APEI_PCIEAER 378c2ecf20Sopenharmony_ci bool "APEI PCIe AER logging/recovering support" 388c2ecf20Sopenharmony_ci depends on ACPI_APEI && PCIEAER 398c2ecf20Sopenharmony_ci help 408c2ecf20Sopenharmony_ci PCIe AER errors may be reported via APEI firmware first mode. 418c2ecf20Sopenharmony_ci Turn on this option to enable the corresponding support. 428c2ecf20Sopenharmony_ci 438c2ecf20Sopenharmony_ciconfig ACPI_APEI_SEA 448c2ecf20Sopenharmony_ci bool 458c2ecf20Sopenharmony_ci depends on ARM64 && ACPI_APEI_GHES 468c2ecf20Sopenharmony_ci default y 478c2ecf20Sopenharmony_ci 488c2ecf20Sopenharmony_ciconfig ACPI_APEI_MEMORY_FAILURE 498c2ecf20Sopenharmony_ci bool "APEI memory error recovering support" 508c2ecf20Sopenharmony_ci depends on ACPI_APEI && MEMORY_FAILURE 518c2ecf20Sopenharmony_ci help 528c2ecf20Sopenharmony_ci Memory errors may be reported via APEI firmware first mode. 538c2ecf20Sopenharmony_ci Turn on this option to enable the memory recovering support. 548c2ecf20Sopenharmony_ci 558c2ecf20Sopenharmony_ciconfig ACPI_APEI_EINJ 568c2ecf20Sopenharmony_ci tristate "APEI Error INJection (EINJ)" 578c2ecf20Sopenharmony_ci depends on ACPI_APEI && DEBUG_FS 588c2ecf20Sopenharmony_ci help 598c2ecf20Sopenharmony_ci EINJ provides a hardware error injection mechanism, it is 608c2ecf20Sopenharmony_ci mainly used for debugging and testing the other parts of 618c2ecf20Sopenharmony_ci APEI and some other RAS features. 628c2ecf20Sopenharmony_ci 638c2ecf20Sopenharmony_ciconfig ACPI_APEI_ERST_DEBUG 648c2ecf20Sopenharmony_ci tristate "APEI Error Record Serialization Table (ERST) Debug Support" 658c2ecf20Sopenharmony_ci depends on ACPI_APEI 668c2ecf20Sopenharmony_ci help 678c2ecf20Sopenharmony_ci ERST is a way provided by APEI to save and retrieve hardware 688c2ecf20Sopenharmony_ci error information to and from a persistent store.
