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].

Hi infra, I remembered I did submit an issue to request sychronization for SIG information between gitee.com/community/sig/sigs.yaml and website, but I couldn't find it. I check the current status but stil not sure it is done or not. Could anyone help to check? -- Regards Fred Li (李永乐)

Hi, TC members, For the reason that more and more topics are added in meeting. I think we should do a ranking work. I propose we should arrange SIG apply topic in high priority in meeting. What about you guys?

Re: 新增RaspberryPi提案
by Hanjun Guo 27 Mar '20

27 Mar '20

谢谢，我初步看了代码，确实改动非常多（不仅仅是代码行数，还有改动的文件也非常多），没想到RaspberryPi有这么多代码没进主线。有几个问题想确认下： 1. 所有的RaspberryPi板子都要支持吗？我看有arm32的板子，目前openEuler不支持arm32，也没有相关的构建； 2. 里面有非常多的驱动，我们能否选一些关键的驱动先做支持？谢谢，郭寒军 On 2020/3/25 12:11, 方亚芬 wrote: > Here is our kernel source of RaspberryPi for openEuler : > https://gitee.com/eulixos/kernel/tree/openEuler1.0-base-raspi/ > > Yafen > >> -----原始邮件----- >> 发件人: "Hanjun Guo" <guohanjun(a)huawei.com> >> 发送时间: 2020-03-25 10:53:23 (星期三) >> 收件人: "方亚芬" <yafen(a)iscas.ac.cn>, tc(a)openeuler.org >> 抄送: "Xie XiuQi" <xiexiuqi(a)huawei.com> >> 主题: Re: [Tc] 新增RaspberryPi提案 >> >> +Cc Xiuqi >> >> Hi Yafen, >> >> Could you please provide the diff statistics for >> the RaspberryPi support? using "git diff --stat" or >> "git log --stat your_raspberrypi_commits" to get the data. >> >> I don't have email address from Jianmin, so did't cc >> him, sorry for that, please cc him if needed. >> >> Thanks >> Hanjun >> >> On 2020/3/13 20:44, 方亚芬 via Tc wrote: >>> openEuler技术委员会的老师，您好。我是中国科学院软件研究所智能软件研究中心的方亚芬，目前参与软件所与华为在openEuler方面的合作，负责openEuler向树莓派的移植部分工作。 >>> 申请在openEuler社区开通SIG：RaspberryPi，PR链接为：https://gitee.com/openeuler/community… 。 >>> >>> 烦请处理，谢谢。 >>> >>> >>> -- >>> 祝工作顺利，生活愉快。 >>> >>> ------------------------------------------ >>> 方亚芬 >>> 中国科学院软件研究所智能软件研究中心 >>> 邮箱：yafen(a)iscas.ac.cn <mailto:jiran@iscas.ac.cn> >>> 地址：北京市海淀区中关村南四街4号5楼 >>> >>> >>> _______________________________________________ >>> Tc mailing list -- tc(a)openeuler.org >>> To unsubscribe send an email to tc-leave(a)openeuler.org >>> > > > -- > 祝工作顺利，生活愉快。 > > > ------------------------------------------ > 方亚芬 > 中国科学院软件研究所智能软件研究中心 > 邮箱：yafen(a)iscas.ac.cn > 地址：北京市海淀区中关村南四街4号5楼 >

今天TC会议议题纪要：议题1 Add WukongOS (WebOS)sig ->zhangpan 1. TC同意暂时关闭此PR，重新创建 WASI-sig，做底层技术储备，着重打造工具链 2. wasi和webos的趋势存在一致性，webos可以和wasi结合，但不一定绑定，后期在wasi或传统webos技术之上做出webos的demo 议题2: Add RaspberryPi SIG ->方亚芬会议纪要： 1. RaspberryPi针对内核的修改需要回合到openeuler kernel主线，以避免重新拉仓库导致后续openeuler kernel升级带来的维护等相关问题 2. RaspberryPi的用户态脚本可以单独出rpm包，打包流程参考openeuler新报引入流程 3. 针对内核修改代码自动化测试方法需要跟kernel maintainer对齐 4. 后续RaspberryPi出版本节奏与openeuler保持一致议题3：工具引入及社区治理 -> xiongwei (myeuler) 1. 统一引入所列的工具，TC原则上接收引入符合openeuler规范的工具，相关工具引入可以直接通过所属SIG组决定 2. SIG组运作情况例行审视，由xiongwei负责 3. 同意package语言包选择，后续考虑在引入新包时作为必填项议题4： Introduce some big data and ai develop runtime/framework -> zhengxian 纪要： 1.梳理提供基础能力首批引入哪些包，能实现openeuler中自洽，确认开源合规和依赖 2.开源合规问题可以直接咨询律师，其他问题可以在邮件组中讨论 3.具体引入包依照openeuler引入流程议题5： Add DPDK SIG -> humin 纪要： 1. DPDK sig在openEuler的开源定位是面向各种平台和网卡的，不应局限于某一个项目或某款硬件 2. TC同意PR更新后合入议题6： Add bounds_checking_function SIG -> zhaozhijian 纪要： 1、同意bounds_checking_function的申请。 2、刷新README.md文件，说明我们遵循的是C11标准，开源的函数比C11少的逻辑是什么，以及后续的规划是什么？议题7： A-Tune status report -> Shanshishi 纪要： 1、社区资料做分层改进，提供快速上手、白皮书、详细参考等 2、以用户真实需求驱动项目版本开发和演进 3、拓展用户，可以对商业产品与合作伙伴进行推荐吸引 4、开发需求要根据用户真实需求进行优先级调整议题8：Add UKUI sig -> Joey Ma 纪要：TC同意引入UKUI, 对应的PR审视后合入议题9：Add ebpf-xdp sig -> zhengxian --->未讨论，转入下次会议议题 From: Zhanghailiang via Tc [mailto:tc@openeuler.org] Sent: Wednesday, March 25, 2020 9:22 AM To: tc(a)openeuler.org Cc: Joey Ma <majunjiev(a)gmail.com>;

[tc][package]About how to manage and maintain packages/dependencies
by Fred Li 25 Mar '20

25 Mar '20

Hi TC members, Infrastructure team and community members, Recently there are many issues about adding dependencies or new packages [1][2][3]. As a linux operating system, it is extremely critical to manage the dependencies. As we know, Technical committee is managing the packages management policy, however who maintain the new packages is not clear. I have draft idea on this. Please give your advice, opinions on how to maintain the dependencies. - policy. Dependencies are still packages, thus they follow the flow on how to introduce the packages into openEuler community. - Who to maintain: if the packages are new and only dependencies, probably one specific team is an option to do this. - How to automate: Infrastructure should provide a function on getting update from upstream automatically - Dependencies management: an expert should maintain the detailed work on how to choose for ISO and yum for each specific version of release.
