From 894c26a1c274b8eafbb4b1dad67e70e51a106061 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Wed, 30 Sep 2020 22:05:42 +0800 Subject: ACPI: Support Generic Initiator only domains Generic Initiators are a new ACPI concept that allows for the description of proximity domains that contain a device which performs memory access (such as a network card) but neither host CPU nor Memory. This patch has the parsing code and provides the infrastructure for an architecture to associate these new domains with their nearest memory processing node.
