From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Jones Subject: [kvm-unit-tests PATCH v4 17/17] powerpc/ppc64: make a fake debug-exit Date: Mon, 15 Feb 2016 14:49:26 +0100 Message-ID: <1455544166-19766-18-git-send-email-drjones@redhat.com> References: <1455544166-19766-1-git-send-email-drjones@redhat.com> Cc: thuth@redhat.com, dgibson@redhat.com, david@gibson.dropbear.id.au, agraf@suse.de, lvivier@redhat.com, pbonzini@redhat.com To: kvm@vger.kernel.org, kvm-ppc@vger.kernel.org Return-path: Received: from mx1.redhat.com ([209.132.183.28]:60993 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753354AbcBONua (ORCPT ); Mon, 15 Feb 2016 08:50:30 -0500 In-Reply-To: <1455544166-19766-1-git-send-email-drjones@redhat.com> Sender: kvm-owner@vger.kernel.org List-ID: We should use a QEMU debug-exit device like chr-testdev, but for now we just fake things by outputting the exit code (which we parse later) and quitting with RTAS (which always exits with zero). (When we've got a real debug-exit working, then this patch can be reverted.)
