Thanks a lot for your patchset, I took a detail look at this patchset, and it looks good to me, I'm pretty happy that this patchset was backported from mainline kernel and you are the maintainer. For this patchset, Reviewed-by: Hanjun Guo <guohanjun(a)huawei.com> BTW, do we need updates for compiler, glibc and other usersapce package to recognize Hygon processor or performance optimization? if yes, you can send those patches to openEuler as well. And I kindly invite you to create a new SIG for Hygon processor in openEuler [1].

openEuler 20200415 TC纪要   议题一、ROS sig 申请 1、同意申请，但openEuler本身闭源的软件治理还没有梳理清楚，建议先不包括闭源内容。议题二、SDS sig 申请 1、成立分布式存储sig是有必要的，但是当前maintainer未明确，待分布式存储 maintainer 待定后，再进行申请。 2、当前适配的ceph-depoly/ceph-ansible 等工具完成适配后，直接提交PR申请，暂时纳入storage-sig 组进行管理。议题三、Compatible-sig 申请 1、同意在社区成立兼容性sig 组申请。 2、同意在sig组下增加服务器兼容性(OE cert)、并提供相关介绍材料及文档。 3、兼容性清单需要单独在社区呈现。议题四、 1. 软件包在source-openEuler 发布按照现有sig维度发布，网络类软件包归属network sig，系统运维类软件包归属dev-utils sig 2. openEuler上创建一个eBPF-xdp 项目（名称暂定），用于一些创新项目、不成熟软件包的开发、维护工作。遗留问题：原PR需要刷新-luzhihao 议题五：现有 SIG 运作review 1、 需要明确基于一致性检查识别200多软件包的重新归属问题，以及others里面的包重新梳理 2、 不同sig组的重新定位，比如DB和storage 3、 后续例会要例行review 各sig的运作情况遗留问题：梳理清单以及分工-huxinwei 议题六：rpm package命名讨论 1、 先保持命名现状，避免影响升级等问题。后续软件包版本命名一致性规则由xiongwei制定，评审后发布。议题七：Remove PRM包规则 1、建议在LTS版本周期内不能直接删除包，下一个版本要删除的话也要在repo保留。遗留问题：梳理增包，删包流程并发布-huxinwei ---Original--- From: "Meeting Book via Tc"<tc(a)openeuler.org> Date: Wed, Apr 15, 2020 09:21 AM To: "tc"<tc(a)openeuler.org>; Subject: [Tc] 【Meeting Notice】openEuler TC meeting Time: 2020-04-15 10:00-12:00 Topic openEuler TC meeting Time 2020-04-15 10:00-12:00((UTC+08:00)Beijing)   Join Conference Join (External) >> Meeting ID 929 074 130 76   Convener 王勋   Agenda 1.
