This makes UPIU command trace useless in problem shooting in case we receive a trace log from the customer/field. There are two important fields in RSP UPIU: 1. The response field, which indicates the UFS defined overall success or failure of the series of Command, Data and RESPONSE UPIU’s that make up the execution of a task. 2. The Status field, which contains the command set specific status for a specific command issued by the initiator device. Before this patch, the UPIU paired trace events: ufshcd_upiu: send_req: fe3b0000.ufs: HDR:01 20 00 1c 00 00 00 00 00 00 00 00, CDB:3b e1 00 00 00 00 00 00 30 00 00 00 00 00 00 00 ufshcd_upiu: complete_rsp: fe3b0000.ufs: HDR:01 20 00 1c 00 00 00 00 00 00 00 00, CDB:3b e1 00 00 00 00 00 00 30 00 00 00 00 00 00 00 After the patch: ufshcd_upiu: send_req: fe3b0000.ufs: HDR:01 20 00 1c 00 00 00 00 00 00 00 00, CDB:3b e1 00 00 00 00 00 00 30 00 00 00 00 00 00 00 ufshcd_upiu: complete_rsp: fe3b0000.ufs: HDR:21 00 00 1c 00 00 00 00 00 00 00 00, CDB:3b e1 00 00 00 00 00 00 30 00 00 00 00 00 00 00 Signed-off-by: Bean Huo Reviewed-by: Can Guo --- drivers/scsi/ufs/ufshcd.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/scsi/ufs/ufshcd.c b/drivers/scsi/ufs/ufshcd.c index 85590d3a719e..c5754d5486c9 100644 --- a/drivers/scsi/ufs/ufshcd.c +++ b/drivers/scsi/ufs/ufshcd.c @@ -302,11 +302,17 @@ static void ufshcd_add_cmd_upiu_trace(struct ufs_hba *hba, unsigned int tag, enum ufs_trace_str_t str_t) { struct utp_upiu_req *rq = hba->lrb[tag].ucd_req_ptr; + struct utp_upiu_header *header; if (!trace_ufshcd_upiu_enabled()) return; - trace_ufshcd_upiu(dev_name(hba->dev), str_t, &rq->header, &rq->sc.cdb, + if (str_t == UFS_CMD_SEND) + header = &rq->header; + else + header = &hba->lrb[tag].ucd_rsp_ptr->header; + + trace_ufshcd_upiu(dev_name(hba->dev), str_t, header, &rq->sc.cdb, UFS_TSF_CDB); } From patchwork Mon May 31 10:43:08 2021 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Bean Huo X-Patchwork-Id: 450655 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=-15.7 required=3.0 tests=BAYES_00,DKIM_SIGNED, DKIM_VALID,DKIM_VALID_AU,FREEMAIL_FORGED_FROMDOMAIN,FREEMAIL_FROM, 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 5F238C47080 for ; Mon, 31 May 2021 10:43:42 +0000 (UTC) Received: from vger.kernel.org (vger.kernel.org [23.128.96.18]) by mail.kernel.org (Postfix) with ESMTP id 41D7A60FF3 for ; Mon, 31 May 2021 10:43:42 +0000 (UTC) Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S231384AbhEaKpR (ORCPT ); Mon, 31 May 2021 06:45:17 -0400 Received: from lindbergh.monkeyblade.net ([23.128.96.19]:49882 "EHLO lindbergh.monkeyblade.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S231382AbhEaKpG (ORCPT ); Mon, 31 May 2021 06:45:06 -0400 Received: from mail-ej1-x62c.google.com (mail-ej1-x62c.google.com [IPv6:2a00:1450:4864:20::62c]) by lindbergh.monkeyblade.net (Postfix) with ESMTPS id 56CA9C061760; Mon, 31 May 2021 03:43:25 -0700 (PDT) Received: by mail-ej1-x62c.google.com with SMTP id lz27so15964043ejb.11; Mon, 31 May 2021 03:43:25 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=from:to:cc:subject:date:message-id:in-reply-to:references :mime-version:content-transfer-encoding; bh=QJR89/55KXiudMnlzBPyQOfHeATecr68iMPdF7Lg45k=; b=K1CXkY67aICkk8XQVHakyjkkVxcPKI0OgTVvMhRn0798culLJyaL453W0qgY4Uhk6N vTR7zkfwIqMcFLegI0Yf3/meTKtrU/yDDQFU5qTytk9RaRgqM1Mfa2fQX3glxfM2EOID Y5Gs3ZIcqC/NO72M0Olou7LZ0FQJwekMhY+90afE9JRtLgAPPCpfQZAEVcqZ8tDBtIsN jTXMX9H524WiujyAW4oOXDo0g/c5JOYcsSAZEuPRVIeDGcPqXN2sclbF60Ya4KmDF9m1 Q5bgMdFWTGDSlBFZWNybZB3Iy96ksD9XKpa+auj4FXGP186ORO8gtrqaqXIM5e9pYqZd +Z1w== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:from:to:cc:subject:date:message-id:in-reply-to :references:mime-version:content-transfer-encoding; bh=QJR89/55KXiudMnlzBPyQOfHeATecr68iMPdF7Lg45k=; b=SVY/3lNHV6UGLn3DPi0dKIs6RV4OPwINjl19efFUESDSNKLn1L/q4DuR5FuOfJRrIV VvUjqi/CBtRV+HUcfb228Lt7U1jcC38ObDn126Z1Mzqjpb61/I9An/lnut4MvcHz49zE RM/WwvgGLgjA+UUWvsgmWRHtk4tmhhe+XRoJ3BwIRJMQTWTSQ1hcxL2RN7vnRVTaTZw7 TMl5BJPZQDxpnZvSwSUsqBdRsblriI0cYtjZfyH6JZTwqIQamPmx5vGqBrWbLSVeYd6i oAw3TkZdzDyhcA/JQuEQEkgNgblPU38o+svGgI4WV/EoX3/CGMIo/QyTcKlbXpXu5oKp 7zZA== X-Gm-Message-State: AOAM5317d1Irl0CO+Cd1ZZpuc3XyysJBt9gZZlMQH9/yAMmlJ5MD05IX lAAYNuk/CEeuISWpSCM9l20= X-Google-Smtp-Source: ABdhPJxDJvrgYdIK8f0tjjYwr6p6Uz/eVz7Ds1pKwC2HivAzFIfzlLx594swmbjxCRutv/Gr/5IFmw== X-Received: by 2002:a17:906:c0c6:: with SMTP id bn6mr21272637ejb.436.1622457803973; Mon, 31 May 2021 03:43:23 -0700 (PDT) Received: from localhost.localdomain (ip5f5bec5d.dynamic.kabel-deutschland.de.
