The kernel will internally + * pad them out to the next 2MB boundary. As this only wastes virtual + * address space and avoids userland having to copy any needlessly + * complicated PDE sharing scheme (coloring) and only affects DG2, this + * is deemed to be a good compromise. */ __u64 size; /** @@ -3282,4 +3508,4 @@ struct drm_i915_gem_create_ext_protected_content { } #endif -#endif /* _I915_DRM_H_ */ +#endif /* _UAPI_I915_DRM_H_ */ From patchwork Fri Jun 3 00:54:04 2022 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 8bit X-Patchwork-Submitter: John Harrison X-Patchwork-Id: 12868405 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 CA74BCCA47B for ; Fri, 3 Jun 2022 00:54:08 +0000 (UTC) Received: from gabe.freedesktop.org (localhost [127.0.0.1]) by gabe.freedesktop.org (Postfix) with ESMTP id 0474810F344; Fri, 3 Jun 2022 00:54:08 +0000 (UTC) Received: from mga07.intel.com (mga07.intel.com [134.134.136.100]) by gabe.freedesktop.org (Postfix) with ESMTPS id 6E24F10E7E4; Fri, 3 Jun 2022 00:54:05 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=intel.com; i=@intel.com; q=dns/txt; s=Intel; t=1654217645; x=1685753645; h=from:to:cc:subject:date:message-id:in-reply-to: references:mime-version:content-transfer-encoding; bh=JJIIT3wXfo61SIDl0+/6447iM1Y33tboksnvm9J5v6o=; b=Z74AmP1BcfdDJ367cG2exY9YWBGG131W6Etg7ml2/W95b9WWKm7Ldikc 9sf8PCbpmtOd11FgYNEvXERZOEcIH6dLkizKSPgNRQc74D7giVKr4G6hn uCv1vOyaRe6z+2doj71tlh//qSXr/E8JFevNraxC3m5ZqQzv1732aDEEN /NXnW4FXvD4bkEqpFBKLTGxS5BBEUXwVOdC2+eP3MfvNNNlHQmkULGHSm BZYOJO6tUhPCiAyLc5YEErJhLOyir/ppoBH61qwPGW7AkSZOYiyH8KtEr gw/n7TEwUOKm/9DQKjXjrLNGH5hhMP38noJlymG6Gcxjrf6EjkopGiT4Y Q==; X-IronPort-AV: E=McAfee;i="6400,9594,10366"; a="339174842" X-IronPort-AV: E=Sophos;i="5.91,273,1647327600"; d="scan'208";a="339174842" Received: from orsmga004.jf.intel.com ([10.7.209.38]) by orsmga105.jf.intel.com with ESMTP/TLS/ECDHE-RSA-AES256-GCM-SHA384; 02 Jun 2022 17:54:04 -0700 X-ExtLoop1: 1 X-IronPort-AV: E=Sophos;i="5.91,273,1647327600"; d="scan'208";a="707827189" Received: from relo-linux-5.jf.intel.com ([10.165.21.134]) by orsmga004.jf.intel.com with ESMTP; 02 Jun 2022 17:54:04 -0700 From: John.C.Harrison@Intel.com To: IGT-Dev@Lists.FreeDesktop.Org Date: Thu, 2 Jun 2022 17:54:04 -0700 Message-Id: <20220603005404.2209038-3-John.C.Harrison@Intel.com> X-Mailer: git-send-email 2.36.0 In-Reply-To: <20220603005404.2209038-1-John.C.Harrison@Intel.com> References: <20220603005404.2209038-1-John.C.Harrison@Intel.com> MIME-Version: 1.0 Organization: Intel Corporation (UK) Ltd. - Co.

This table can be retrieved from the KMD via the existing query API. So add a test for it as both an example of how to fetch the table and to validate the contents as much as is possible.
