From f6f56692227952864edcb0dc841cde6238470cf8 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Mon, 21 Jan 2019 17:05:59 +0100 Subject: [PATCH 14/14] s390x: Return specification exception for unimplemented diag 308 subcodes RH-Author: Cornelia Huck Message-id: <20190121170559.19471-1-cohuck@redhat.com> Patchwork-id: 84074 O-Subject: [RHEL-7.6.z qemu-kvm-ma PATCH] s390x: Return specification exception for unimplemented diag 308 subcodes Bugzilla: 1668424 RH-Acked-by: Thomas Huth RH-Acked-by: David Hildenbrand RH-Acked-by: John Snow From: Janosch Frank The architecture specifies specification exceptions for all unavailable subcodes. The presence of subcodes is indicated by checking some query subcode. For example 6 will indicate that 3-6 are available. So future systems might call new subcodes to check for new features. This should not trigger a hw error, instead we return the architectured specification exception.
