This is a pseduo-unique magic number that is meant to distinguish similar seeming bugs with different underlying signatures. It is a combination of two ring state registers. Unfortunately, the register state being used is only valid in execlist mode. In GuC mode, the register state exists in a separate list of arbitrary register address/value pairs rather than the named entry structure. So, search through that list to find the two exciting registers and copy them over to the structure's named members. v2: if else if instead of if if (Alan) Signed-off-by: John Harrison Reviewed-by: Alan Previn Fixes: a6f0f9cf330a ("drm/i915/guc: Plumb GuC-capture into gpu_coredump") Cc: Alan Previn Cc: Umesh Nerlige Ramappa Cc: Lucas De Marchi Cc: Jani Nikula Cc: Joonas Lahtinen Cc: Rodrigo Vivi Cc: Tvrtko Ursulin Cc: Matt Roper Cc: Aravind Iddamsetty Cc: Michael Cheng Cc: Matthew Brost Cc: Bruce Chang Cc: Daniele Ceraolo Spurio Cc: Matthew Auld --- .../gpu/drm/i915/gt/uc/intel_guc_capture.c | 22 +++++++++++++++++++ 1 file changed, 22 insertions(+) diff --git a/drivers/gpu/drm/i915/gt/uc/intel_guc_capture.c b/drivers/gpu/drm/i915/gt/uc/intel_guc_capture.c index 101d44de729b1..36196cbb24c6b 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_guc_capture.c +++ b/drivers/gpu/drm/i915/gt/uc/intel_guc_capture.c @@ -1562,6 +1562,27 @@ int intel_guc_capture_print_engine_node(struct drm_i915_error_state_buf *ebuf, #endif //CONFIG_DRM_I915_CAPTURE_ERROR +static void guc_capture_find_ecode(struct intel_engine_coredump *ee) +{ + struct gcap_reg_list_info *reginfo; + struct guc_mmio_reg *regs; + i915_reg_t reg_ipehr = RING_IPEHR(0); + i915_reg_t reg_instdone = RING_INSTDONE(0); + int i; + + if (!ee->guc_capture_node) + return; + + reginfo = ee->guc_capture_node->reginfo + GUC_CAPTURE_LIST_TYPE_ENGINE_INSTANCE; + regs = reginfo->regs; + for (i = 0; i < reginfo->num_regs; i++) { + if (regs[i].offset == reg_ipehr.reg) + ee->ipehr = regs[i].value; + else if (regs[i].offset == reg_instdone.reg) + ee->instdone.instdone = regs[i].value; + } +} + void intel_guc_capture_free_node(struct intel_engine_coredump *ee) { if (!ee || !ee->guc_capture_node) @@ -1601,6 +1622,7 @@ void intel_guc_capture_get_matching_node(struct intel_gt *gt, list_del(&n->link); ee->guc_capture_node = n; ee->guc_capture = guc->capture; + guc_capture_find_ecode(ee); return; } } From patchwork Fri Feb 17 02:24:19 2023 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: John Harrison X-Patchwork-Id: 13144214 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 gabe.freedesktop.org (gabe.freedesktop.org [131.252.210.177]) (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 4233EC636CC for ; Fri, 17 Feb 2023 02:25:30 +0000 (UTC) Received: from gabe.freedesktop.org (localhost [127.0.0.1]) by gabe.freedesktop.org (Postfix) with ESMTP id 613C810E3C9; Fri, 17 Feb 2023 02:25:13 +0000 (UTC) Received: from mga03.intel.com (mga03.intel.com [134.134.136.65]) by gabe.freedesktop.org (Postfix) with ESMTPS id 5D6A210E195; Fri, 17 Feb 2023 02:25:04 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=intel.com; i=@intel.com; q=dns/txt; s=Intel; t=1676600704; x=1708136704; h=from:to:cc:subject:date:message-id:in-reply-to: references:mime-version:content-transfer-encoding; bh=9xJ78ZPjSwZj2s9QdeqUFq5jM7hTALRDfyEnmi9fAbM=; b=nUb2nnGpawPFVP0ROiLzwl7fE0OKoTXtxa18gLr7aKI4AUzdZo0g3Zl1 1PtSOhAQL2XqBV9g8fprt2whzC1jDN6se5VOZhuLNiXDrlX4T5rIto6S4 sjiOD+8GA0Cn4stdl26ZAfoOYeBO58QHIaStbncOEsw6ZhhTkucI+xIsK MW1gaeJOjclFUgKi8evXXcAW3VKKpU4Sk/b5Bhy1wc38FypF5EBGPwRzc Xph7XWIYO+i2EzwbtFxtNfSRBlX19Kqdkz2tFgiThw4NSNMaQ+XL0NIJN 0L1LzQ+9NZA4LwayhiGzcTVeqcxfFWFuX4noohxDs+IZ1Wl9eeOwewg+V w==; X-IronPort-AV: E=McAfee;i="6500,9779,10623"; a="334093365" X-IronPort-AV: E=Sophos;i="5.97,304,1669104000"; d="scan'208";a="334093365" Received: from orsmga002.jf.intel.com ([10.7.209.21]) by orsmga103.jf.intel.com with ESMTP/TLS/ECDHE-RSA-AES256-GCM-SHA384; 16 Feb 2023 18:25:02 -0800 X-ExtLoop1: 1 X-IronPort-AV: E=McAfee;i="6500,9779,10623"; a="670389089" X-IronPort-AV: E=Sophos;i="5.97,304,1669104000"; d="scan'208";a="670389089" Received: from relo-linux-5.jf.intel.com ([10.165.21.152]) by orsmga002.jf.intel.com with ESMTP; 16 Feb 2023 18:25:02 -0800 From: John.C.Harrison@Intel.com To: Intel-GFX@Lists.FreeDesktop.Org Date: Thu, 16 Feb 2023 18:24:19 -0800 Message-Id: <20230217022420.2664116-3-John.C.Harrison@Intel.com> X-Mailer: git-send-email 2.39.1 In-Reply-To: <20230217022420.2664116-1-John.C.Harrison@Intel.com> References: <20230217022420.2664116-1-John.C.Harrison@Intel.com> MIME-Version: 1.0 Organization: Intel Corporation (UK) Ltd. - Co.
