It's like
acpi_extlog.cin that it uses an ACPI DSM. Also related to error reporting. No, we aren't abandoning extlog, but it seems that fewer OEMs than we hoped are adopting eMCA and implementing the extended log in their BIOS.

Ok, but what is the difference with this DSM thing and why would OEMs use that? They get it for free from you? Or?
This shouldn't conflict with other BIOS "value add" code for firmware first mode, etc.
Yes, they get it for free with the reference/example BIOS code.
Btw, have you seen this GHES_ASSIST thing in the ACPI 6.2 spec?
"Bit [2] - GHES_ASSIST: If set, this bit indicates that although OSPM is responsible for directly handling the error (as expected when FIRMWARE_FIRST is not set), system firmware reports additional information in the context of an exception generated by the error. The additional information is reported in a Generic Hardware Error Source structure with a matching Related Source Id."
I'm being told this will tell you DIMM ID and FRU too...
