From 5bb9f99d9dbe71424f656f597b650d5088faca23 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Fri, 29 Mar 2019 11:13:35 +0000 Subject: [PATCH 1/7] s390x/cpumodel: mepochptff: warn when no mepoch and re-align group init RH-Author: Thomas Huth Message-id: <1553858017-376-2-git-send-email-thuth@redhat.com> Patchwork-id: 85237 O-Subject: [RHEL-8.1.0 qemu-kvm PATCH 1/3] s390x/cpumodel: mepochptff: warn when no mepoch and re-align group init Bugzilla: 1664371 RH-Acked-by: David Hildenbrand RH-Acked-by: Cornelia Huck RH-Acked-by: Jens Freimann From: Collin Walling The extended PTFF features (qsie, qtoue, stoe, stoue) are dependent on the multiple-epoch facility (mepoch). Let's print a warning if these features are enabled without mepoch. While we're at it, let's move the FEAT_GROUP_INIT for mepochptff down the s390_feature_groups list so it can be properly indexed with its generated S390FeatGroup enum.
