Hi Shiju,
The configuration "CONFIG_ACPI_APEI_SEA" is needed to manually enable?
In the "drivers/acpi/apei/Kconfig" file, the default value of ACPI_APEI_SEA is "y"
config ACPI_APEI_SEA
bool "APEI Synchronous External Abort logging/recovering support"
depends on ARM64 && ACPI_APEI_GHES
default y
help
This option should be enabled if the system supports
firmware first handling of SEA (Synchronous External Abort).
SEA happens with certain faults of data abort or instruction
abort synchronous exceptions on ARMv8 systems. If a system
supports firmware first handling of SEA, the platform analyzes
and handles hardware error notifications from SEA, and it may then
form a HW error record for the OS to parse and handle. This
option allows the OS to look for such hardware error record, and
take appropriate action.
