This(2nd) file is generally imported from ACPICA directly. So you need to work with acpica-devel list(you can cc Robert Moore) to get that alone integrated in acpica projected so that iasl tool and other related components also gain support for this first. If the ACPI tables are generated by UEFI, it would be good to add the support in tianocore project. IIRC tianocore has some PCC reference in Acpi60.h header. It would help if the above two are done before we start looking into Linux changes(pcc.c). To summarize this patch needs to be split. -- Regards, Sudeep -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
