Hi Dongjiu -- it looks like this patch set is extending the API KVM provides to userspace, but it doesn't update the documentation in Documentation/virtual/kvm/api.txt. I appreciate the API is still somewhat under discussion, but if you can include the docs updates it's helpful to me for reviewing whether the API makes sense from the userspace consumer end of it. thanks -- PMM From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1753661AbdIFLTp (ORCPT ); Wed, 6 Sep 2017 07:19:45 -0400 Received: from mail-wr0-f171.google.com ([209.85.128.171]:38596 "EHLO mail-wr0-f171.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753492AbdIFLTn (ORCPT ); Wed, 6 Sep 2017 07:19:43 -0400 X-Google-Smtp-Source: ADKCNb5V+YVndReHqcHFk7/DirbV31NEkYUFkav7OwxBw92bf7LFCFSJ5oAAmRIybS2uLtReDZ1XCRhz/sk01lZgMhU= MIME-Version: 1.0 In-Reply-To: <1503916701-13516-1-git-send-email-gengdongjiu@huawei.com> References: <1503916701-13516-1-git-send-email-gengdongjiu@huawei.com> From: Peter Maydell Date: Wed, 6 Sep 2017 12:19:21 +0100 Message-ID: Subject: Re: [PATCH v6 0/7] Add RAS virtualization support for SEA/SEI notification type in KVM To: Dongjiu Geng Cc: Christoffer Dall , Marc Zyngier , =?UTF-8?B?UmFkaW0gS3LEjW3DocWZ?= , linux@armlinux.org.uk, Catalin Marinas , Will Deacon , lenb@kernel.org, robert.moore@intel.com, lv.zheng@intel.com, Mark Rutland , James Morse , xiexiuqi@huawei.com, Christopher Covington , David Daney , "Suzuki K.
