I meant this fw_cfg file: #define ACPI_HW_ERROR_FW_CFG_FILE "etc/hardware_errors" #define ACPI_HW_ERROR_ADDR_FW_CFG_FILE "etc/hardware_errors_addr" What about changing description to: The etc/hardware_errors fw_cfg file is where the HEST error source structures are stored. Those can be GHESv2, but they can also be other types. For more details about error source structure, see: https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#acpi-error-source Better name the address variable from ghes_error_le to hw_error_le to better reflect that.
