The +latter was mainly a requirement for running KVM on 32-bit arm hosts, but +this 32-bit KVM support has been removed three years ago already (see: +https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=541ad0150ca4 +). Thus the QEMU project will drop the ``qemu-system-arm`` binary in a +future release. Use ``qemu-system-aarch64`` instead. + System emulator command line arguments -------------------------------------- From patchwork Fri Mar 3 10:14:52 2023 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 8bit X-Patchwork-Submitter: Thomas Huth X-Patchwork-Id: 13158620 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org Received: from lists.xenproject.org (lists.xenproject.org [192.237.175.120]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.lore.kernel.org (Postfix) with ESMTPS id 56EADC7EE36 for ; Fri, 3 Mar 2023 10:15:25 +0000 (UTC) Received: from list by lists.xenproject.org with outflank-mailman.505713.778640 (Exim 4.92) (envelope-from ) id 1pY2Rb-0003Vf-J6; Fri, 03 Mar 2023 10:15:19 +0000 X-Outflank-Mailman: Message body and most headers restored to incoming version Received: by outflank-mailman (output) from mailman id 505713.778640; Fri, 03 Mar 2023 10:15:19 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1pY2Rb-0003VU-Fi; Fri, 03 Mar 2023 10:15:19 +0000 Received: by outflank-mailman (input) for mailman id 505713; Fri, 03 Mar 2023 10:15:18 +0000 Received: from se1-gles-flk1-in.inumbo.com ([94.247.172.50] helo=se1-gles-flk1.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1pY2Ra-00022o-8W for xen-devel@lists.xenproject.org; Fri, 03 Mar 2023 10:15:18 +0000 Received: from us-smtp-delivery-124.mimecast.com (us-smtp-delivery-124.mimecast.com [170.10.129.124]) by se1-gles-flk1.inumbo.com (Halon) with ESMTPS id 4aba6be2-b9ac-11ed-a550-8520e6686977; Fri, 03 Mar 2023 11:15:16 +0100 (CET) Received: from mimecast-mx02.redhat.com (mx3-rdu2.redhat.com [66.187.233.73]) by relay.mimecast.com with ESMTP with STARTTLS (version=TLSv1.2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id us-mta-509-bZLmghJgM0iRuMfk4t6oHQ-1; Fri, 03 Mar 2023 05:15:12 -0500 Received: from smtp.corp.redhat.com (int-mx09.intmail.prod.int.rdu2.redhat.com [10.11.54.9]) (using TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits)) (No client certificate requested) by mimecast-mx02.redhat.com (Postfix) with ESMTPS id B90173C0F361; Fri, 3 Mar 2023 10:15:11 +0000 (UTC) Received: from thuth.com (unknown [10.39.192.255]) by smtp.corp.redhat.com (Postfix) with ESMTP id 90C90492C14; Fri, 3 Mar 2023 10:15:09 +0000 (UTC) X-BeenThere: xen-devel@lists.xenproject.org List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Errors-To: xen-devel-bounces@lists.xenproject.org Precedence: list Sender: "Xen-devel" X-Inumbo-ID: 4aba6be2-b9ac-11ed-a550-8520e6686977 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=redhat.com; s=mimecast20190719; t=1677838515; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=TA8n6cCaxiG/TrAIzxGyTy420i7qS2ZnxNV585T25Zs=; b=emO62jFeMgcQTtujjTQRrd8cIpVX1BgmKnv+eryjqgIiuPxH8Tazd9iLDwEbdaSx9CdD3c pJ3QSfPDqlTFKx5G/5dPTB3z4ilncXEGLZ2E3eeLJ+wTlz0mX1CxttsGHO3Y5dyrz9rPoP 3dEdY/RwmoUbkLp43hyakwJ3T515+Ok= X-MC-Unique: bZLmghJgM0iRuMfk4t6oHQ-1 From: Thomas Huth To: qemu-devel@nongnu.org, Peter Maydell , Daniel Berrange , Paolo Bonzini Cc: Markus Armbruster , =?utf-8?q?Alex_Benn=C3=A9e?= , qemu-arm@nongnu.org, Maxim Levitsky , libvir-list@redhat.com, Richard Henderson , xen-devel@lists.xenproject.org, Reinoud Zandijk , Wilfred Mallawa Subject: [PATCH v3 6/6] gitlab-ci.d/crossbuilds: Drop the 32-bit arm system emulation jobs Date: Fri, 3 Mar 2023 11:14:52 +0100 Message-Id: <20230303101452.769367-7-thuth@redhat.com> In-Reply-To: <20230303101452.769367-1-thuth@redhat.com> References: <20230303101452.769367-1-thuth@redhat.com> MIME-Version: 1.0 X-Scanned-By: MIMEDefang 3.1 on 10.11.54.9 Hardly anybody still uses 32-bit arm environments for running QEMU, so let's stop wasting our scarce CI minutes with these jobs.
