This happens because the kernel file arch/powerpc/platform/pseries/hotplug-cpu.c, function dlpar_cpu_remove(), is not finding the device_node.name of the offending CPU. We're not populating the 'name' property for hotplugged CPUs. Since the kernel relies on device_node.name for identifying CPU nodes, and the CPUs that are coldplugged has the 'name' property filled by SLOF, this is creating an unneeded inconsistency between hotplug and coldplug CPUs in the kernel. Let's fill the 'name' property for hotplugged CPUs as well. This will make the guest dmesg throws a less intimidating message when we try to unplug the last online CPU: pseries-hotplug-cpu: Failed to offline CPU PowerPC,POWER9@1, rc: -16 [1] https://bugzilla.redhat.com/1911414 Signed-off-by: Daniel Henrique Barboza Message-Id: <20210120232305.241521-3-danielhb413@gmail.com> Signed-off-by: David Gibson --- hw/ppc/spapr.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/hw/ppc/spapr.c b/hw/ppc/spapr.c index e7992c0422..0ecc193468 100644 --- a/hw/ppc/spapr.c +++ b/hw/ppc/spapr.c @@ -3756,6 +3756,19 @@ int spapr_core_dt_populate(SpaprDrc *drc, SpaprMachineState *spapr, spapr_dt_cpu(cs, fdt, offset, spapr); + /* + * spapr_dt_cpu() does not fill the 'name' property in the + * CPU node.

This happens because the firmware names of PCI devices returned by get_boot_devices_list() come from pcibus_get_fw_dev_path(), while the sPAPR PHB code uses a different naming scheme for device nodes.

Signed-off-by: Alexey Kardashevskiy Signed-off-by: David Gibson Fortunately, sPAPR implements the firmware path provider interface. This provides a way to override the default firmware paths. Just factor out the sPAPR PHB naming logic from spapr_dt_pci_device() to a helper, and use it in the sPAPR firmware path provider hook.

Under QEMU, we emulate this behavior and we also add an extra control on the flash accesses by letting the HIOMAP command handler decide whether the memory region is accessible or not depending on the firmware requests. However, this behavior is not compatible with hostboot like firmwares which need this mapping to be always available. For this reason, the PNOR memory region is initially disabled for skiboot mode only. This is badly placed under the LPC model and requires the use of the machine. Since it doesn't add much, simply remove the initial setting. The extra control in the HIOMAP command handler will still be performed.

The problem is that the initial value of gpu_numa_id, for any topology that has more than one NUMA node, is equal to numa_state->num_nodes. This means that our maxdomain will always be, at least, twice the amount of existing NUMA nodes. This means that a guest with 4 NUMA nodes will end up with the following max-associativity-domains: rtas/ibm,max-associativity-domains 00000004 00000008 00000008 00000008 00000008 This overtuning of maxdomains doesn't go unnoticed in the guest, being detected in SLUB during boot: dmesg | grep SLUB [ 0.000000] SLUB: HWalign=128, Order=0-3, MinObjects=0, CPUs=4, Nodes=8 SLUB is detecting 8 total nodes, with 4 nodes being online. This patch fixes ibm,max-associativity-domains by considering the amount of NVGPUs NUMA nodes presented in the guest, instead of just spapr->gpu_numa_id.

But currently QEMU does the opposite. This commit reverses the RCTRL.RSF testing logic to match the manual. Due to the reverse of the logic, certain guests may potentially break if they don't program eTSEC to have RCTRL.RSF bit set. When RCTRL.RSF is 0, short frames are silently dropped, however as of today both slirp and tap networking do not pad short frames (e.g.: an ARP packet) to the minimum frame size of 60 bytes. So ARP requests will be dropped, preventing the guest from becoming visible on the network. The same issue was reported on e1000 and vmxenet3 before, see: commit 78aeb23eded2 ("e1000: Pad short frames to minimum size (60 bytes)") commit 40a87c6c9b11 ("vmxnet3: Pad short frames to minimum size (60 bytes)") [1] https://www.nxp.com/docs/en/reference-manual/MPC8548ERM.pdf Fixes: eb1e7c3e5146 ("Add Enhanced Three-Speed Ethernet Controller (eTSEC)") Signed-off-by: Bin Meng Message-Id: <1612923021-19746-1-git-send-email-bmeng.cn@gmail.com> Signed-off-by: David Gibson --- hw/net/fsl_etsec/rings.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hw/net/fsl_etsec/rings.c b/hw/net/fsl_etsec/rings.c index 121415abfe..fe055d3381 100644 --- a/hw/net/fsl_etsec/rings.c +++ b/hw/net/fsl_etsec/rings.c @@ -502,7 +502,7 @@ ssize_t etsec_rx_ring_write(eTSEC *etsec, const uint8_t *buf, size_t size) return -1; } - if ((etsec->regs[RCTRL].value & RCTRL_RSF) && (size < 60)) { + if (!(etsec->regs[RCTRL].value & RCTRL_RSF) && (size < 60)) { /* CRC is not in the packet yet, so short frame is below 60 bytes */ RING_DEBUG("%s: Drop short frame\n", __func__); return -1; From patchwork Wed Feb 10 06:17:35 2021 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: David Gibson X-Patchwork-Id: 12079961 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org X-Spam-Level: X-Spam-Status: No, score=-16.6 required=3.0 tests=BAYES_00,DKIM_INVALID, DKIM_SIGNED,HEADER_FROM_DIFFERENT_DOMAINS,INCLUDES_CR_TRAILER,INCLUDES_PATCH, MAILING_LIST_MULTI,SPF_HELO_NONE,SPF_PASS,URIBL_BLOCKED,USER_AGENT_GIT autolearn=ham autolearn_force=no version=3.4.0 Received: from mail.kernel.org (mail.kernel.org [198.145.29.99]) by smtp.lore.kernel.org (Postfix) with ESMTP id 8EE85C433E0 for ; Wed, 10 Feb 2021 06:33:20 +0000 (UTC) Received: from lists.gnu.org (lists.gnu.org [209.51.188.17]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by mail.kernel.org (Postfix) with ESMTPS id 35C5464E30 for ; Wed, 10 Feb 2021 06:33:20 +0000 (UTC) DMARC-Filter: OpenDMARC Filter v1.3.2 mail.kernel.org 35C5464E30 Authentication-Results: mail.kernel.org; dmarc=none (p=none dis=none) header.from=gibson.dropbear.id.au Authentication-Results: mail.kernel.org; spf=pass smtp.mailfrom=qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Received: from localhost ([::1]:50558 helo=lists1p.gnu.org) by lists.gnu.org with esmtp (Exim 4.90_1) (envelope-from ) id 1l9j3v-000352-Ah for qemu-devel@archiver.kernel.org; Wed, 10 Feb 2021 01:33:19 -0500 Received: from eggs.gnu.org ([2001:470:142:3::10]:43524) by lists.gnu.org with esmtps (TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256) (Exim 4.90_1) (envelope-from ) id 1l9ipB-0001pC-VU; Wed, 10 Feb 2021 01:18:06 -0500 Received: from ozlabs.org ([203.11.71.1]:58655) by eggs.gnu.org with esmtps (TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256) (Exim 4.90_1) (envelope-from ) id 1l9ipA-0000RP-23; Wed, 10 Feb 2021 01:18:05 -0500 Received: by ozlabs.org (Postfix, from userid 1007) id 4Db8gq1f0rz9sWY; Wed, 10 Feb 2021 17:17:42 +1100 (AEDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=gibson.dropbear.id.au; s=201602; t=1612937863; bh=RYUEzEzrJ2xfcxGHKwvhXCnhllTzQI/NcsA5f6qpXRI=; h=From:To:Cc:Subject:Date:In-Reply-To:References:From; b=LU/7hL5Jfuf98myJNTILDNplnImrdmWYZqnU3nADCO/rrRL/2NtONczoXFLp9ktWK dFrAsoCroCI8P84fFsGGSW3B4WxXGYCJq+lJaqVyvAQE5TQk50pe4z2OJYWLSvGZtl /Db13V6bTcDxF7UK1f2YxwtaQr91ej1jaVe2gN4o= From: David Gibson To: peter.maydell@linaro.org, groug@kaod.org Subject: [PULL 19/19] target/ppc: Add E500 L2CSR0 write helper Date: Wed, 10 Feb 2021 17:17:35 +1100 Message-Id: <20210210061735.304384-20-david@gibson.dropbear.id.au> X-Mailer: git-send-email 2.29.2 In-Reply-To: <20210210061735.304384-1-david@gibson.dropbear.id.au> References: <20210210061735.304384-1-david@gibson.dropbear.id.au> MIME-Version: 1.0 Received-SPF: pass client-ip=203.11.71.1; envelope-from=dgibson@ozlabs.org; helo=ozlabs.org X-Spam_score_int: -17 X-Spam_score: -1.8 X-Spam_bar: - X-Spam_report: (-1.8 / 5.0 requ) BAYES_00=-1.9, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, HEADER_FROM_DIFFERENT_DOMAINS=0.249, SPF_HELO_PASS=-0.001, SPF_PASS=-0.001 autolearn=no autolearn_force=no X-Spam_action: no action X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Bin Meng , qemu-ppc@nongnu.org, qemu-devel@nongnu.org, David Gibson Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" From: Bin Meng Per EREF 2.0 [1] chapter 3.11.2: The following bits in L2CSR0 (exists in the e500mc/e5500/e6500 core): - L2FI (L2 cache flash invalidate) - L2FL (L2 cache flush) - L2LFC (L2 cache lock flash clear) when set, a cache operation is initiated by hardware, and these bits will be cleared when the operation is complete. Since we don't model cache in QEMU, let's add a write helper to emulate the cache operations completing instantly.
