From 673bc4354d42731018494bb69d63b6513f9ae2bb Mon Sep 17 00:00:00 2001 From: Nathan Fontenot Date: Wed, 11 Jan 2017 12:00:58 -0500 Subject: [PATCH] powerpc/pseries: Report DLPAR capabilities As we add the ability to do DLPAR of additional devices through the sysfs interface we need to know which devices are supported. This adds the reporting of supported devices with a comma separated list reported in the existing /sys/kernel/dlpar.
