From eaf1ffbe15fe67612c63d928415ee04eb4836dc7 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Mon, 12 Oct 2020 13:26:39 +0200 Subject: [PATCH] spapr: Clarify why DR connectors aren't user creatable DR connector is a device that emulates a firmware abstraction used by PAPR compliant guests to manage hotplug/dynamic-reconfiguration of PHBs, PCI devices, memory, and CPUs. It is internally created by the spapr platform and requires to be owned by either the machine (PHBs, CPUs, memory) or by a PHB (PCI devices).
