From e07359f171f2440f4dbc98339b10c8c3cdd48a20 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Thu, 10 Oct 2024 09:01:26 +0200 Subject: [PATCH] powerpc/pseries/lparcfg: Use num_possible_cpus() for potential processors MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The systemcfg processorCount variable tracks currently online variables, not possible ones, so the stored value is wrong. The code preferably tries to use the ibm,lrdr-capacity field 4 which "represents the maximum number of processors that the guest can have." Switch from processorCount to the better matching num_possible_cpus().
