Hi Tony and Gong,
	Should we remove the target memory address from the resource list of
ACPI5 trigger too? Otherwise we may also encounter resource conflict with ACPI5
trigger table.

I'm a little confused about the ACPI_EINJ_SET_ERROR_TYPE_WITH_ADDRESS command in ACPI5.
The above code seems like a hard-coded version of
apei_exec_run(&ctx, ACPI_EINJ_SET_ERROR_TYPE_WITH_ADDRESS).
Hi Gong, could you please share the ACPI5 version of EINJ table with me? So I could
get better understanding of the ACPI_EINJ_SET_ERROR_TYPE_WITH_ADDRESS command.


You can check ACPI5.0 spec 18.6 for detail. We have internal BIOS to support
ACPI5 and I'm not sure if there is external product to support ACPI5 formally.
