1．回顾上周的工作，这一阶段优化同步到openEuler社区的工作已经完成 2． glibc库编译失败，可能原因是gcc的优化导致，目前提交了一个修复补丁，解决部分问题，但glibc包整体上依然编译失败，需要支持解决会上Eric（ARM）提了几个问题： 1． https://gcc.gnu.org/pipermail/gcc-patches/2020-June/546950.html gcc社区原生的问题，会影响HPC场景的编译，ARM的同事Wilco提了一些意见，建议通过修改abi的方式实现，会后我们需要看下基于这个思路如何实现 2．关于Compiler SIG在JDK/GCC上的优化后续upstream的讨论会后和ARM公司的简宁胜做了交流，在OpenJDK上SVE指令的支持进行分工合作，ARM的同事将投入Vector API mask对SVE的支持，Compiler SIG的同事在vector api SVE backend剩余OP的支持工作上进行投入发件人: Meeting Book [mailto:uMeeting@huawei.com] 发送时间: 2020年9月7日 11:25 收件人: dev(a)openeuler.org 主题: [Dev] 【Meeting Notice】Compiler SIG weekly meeting Time: 2020-09-08 10:00-11:00 Topic Compiler SIG weekly meeting Time 2020-09-08 10:00-11:00((UTC+08:00)Beijing) Join Conference Join (External) >><https://welink-meeting.zoom.us/j/162757639> Meeting ID 162 757 639 Convener 郭歌 Tips: Dial the access number to join conference<http://app.huawei.com/eshare/voiceMeetings> 注：仅支持部分国家和地区。( Only some countries and regions are supported.) 如果加入会议提示“会议已结束或会议号不存在”，请在官网下载最新版本入会。立即下载<https://zoom.us/download> If a message is displayed, indicating that the meeting has ended or the meeting ID does not exist, download the latest meeting client and try again.Download<https://zoom.us/download>

你好，目前openEuler的主干以及20.03版本都已经升级到10.0.1了，但是补丁还没有发布，待补丁发布后，预期可以在 http://repo.openeuler.org/openEuler-20.03-LTS/update/aarch64/Packages/ 下面看到供升级的包（也有可能有别的提供方式，比如在sp版本中提供，这个要看release-management SIG的安排）对于将llvm升级到11.0.0版本，我认为现在还不是最好的时机，因为11.0.0版本社区实际上还没有发布最终正式版本，目前只有rc版本，请见 http://llvm.org/，我们会在社区发布final版本的时候升级至最新版本我们致力于为openEuler社区提供【最具竞争力的】【稳定版本】，对于一些包我们会保持活跃的开发态，和上游社区的开发状态保持一致，但llvm目前还不在此列祝好发件人: 妞妞乖乖妈妈 [mailto:jeremiah.shi@qq.com] 发送时间: 2020年9月8日 7:49 收件人: guoge (A) <guoge1(a)huawei.com> 抄送: Zhanghaijian (A) <z.zhanghaijian(a)huawei.com>; liuzhiqiang (I) <liuzhiqiang26(a)huawei.com>; 502874763 <502874763(a)qq.com> 主题: Re: 答复: Clang在openeuler编译，求助亲爱的郭歌@jdkboy，早上好，我在openEuler 20.03 TLS everything 的安装还需要再更新一下安装库。昨天在Ubuntu 20.4环境下，已经部署成功了 Clang 10.0.0.4. 近期我在关注Clang code static Anayzer. 如果能OpenEuler上升级到Clang 10.0.0.X，也是很不错的：）在社区里，我找到了源代码包：clang-10.0.1.src.tar，没有能够编译成功。这方面，还请教您，看看可不可以在移植到openEuler上，我们保持好一点的成绩。从Mac OS 10.15来看，Apple的成绩是 Clang 11.X. 亟盼佳音：） Shalom Anno Domini 2020-09-08-7:48 jeremiah@jeremiah-VirtualBox:~/Desktop$ sudo aptitude install clang sudo: aptitude: command not found jeremiah@jeremiah-VirtualBox:~/Desktop$ ps aux | grep -i apt root 2655 0.4 1.1 196788 90764 ?

Jtreg is launching!
by hedongbo 07 Sep '20

07 Sep '20

jtreg is the test harness used by the JDK test framework. This framework is intended primarily for regression tests. It can also be used for unit tests, functional tests, and even simple product tests. It is the latest version without CVE. We have set up a repo request[1] in openEuler.

Virt sig会议议程纪要： 1、openEuler 20.09虚拟化特性代码已经合入，正在进行稳定性和可靠性等测试。 a) vcpu hotplug/mem hotplug/HPRE加速三个特性已经测试完成。 b) 虚拟机可信启动/安全启动/PMU NMI-Watchdog/双层调度等特性正在开展测试中; c) VMtop、ARM虚拟机支持超线程、ARM虚拟机cpu feature支持Custom三个特性尚未开展测试，正在分析及测试设计； 2、EulerRobot质量体系构建进展： a) EulerRobot已经开源，已有部分开发者参与，希望后续有更多开发者参与，共同完善和优化openEuler虚拟化质量体系。 b) crystal-ci当前存在物理机部署后卡死无法使用情况，crystal-ci团队解决中，等解决完后再进行对接。 c) openEuler下虚拟化qemu/libvirt等仓库，代码门禁已经OK，正在实现让qemu/libvirt仓库代码合入后自动化生成Patch同步到src-openEuler中便于版本rpm制作，后续代码提交将切换至openeuelr仓库。 3、openEuler 支持riscv虚拟化的进展如下，后续主要进行bugfix。 a) Qemu支持RISC-V架构的KVM； b) 支持RISC-V架构虚拟机热迁移； c) 支持vhost的ioeventfd方案； From: Chenzhendong (alex) via Virt [mailto:virt@openeuler.org] Sent: Friday, September 4, 2020 10:19 AM To: virt(a)openeuler.org; dev(a)openeuler.org Cc: Zhangxiaofeng (F) <victor.zhangxiaofeng(a)huawei.com> Subject: [Virt] 【Meeting Notice】Virt sig meeting Time: 2020-09-04 14:30-15:30 Virt sig会议议程： 1、openEuler 20.09 虚拟化特性进展 alexchen 2、EulerRobot质量体系构建进展 kuhnchen 3、openEuler RISC-V虚拟化支持进展 Jiangyifei ------- 原始邮件 -------- 发件人： Meeting Book <uMeeting(a)huawei.com<mailto:uMeeting@huawei.com>> 日期： 2020年9月4日周五 10:03 收件人： zdchenhn(a)163.com<mailto:zdchenhn@163.com> 主题：【Meeting Notice】Virt sig meeting Time: 2020-09-04 14:30-15:30 Topic Virt sig meeting Time 2020-09-04 14:30-15:30((UTC+08:00)Beijing) Join Conference Join (External) >><https://welink-meeting.zoom.us/j/258690350> Meeting ID 258 690 350 Convener 陈振东 Tips: Dial the access number to join conference<http://app.huawei.com/eshare/voiceMeetings> 注：仅支持部分国家和地区。( Only some countries and regions are supported.) 如果加入会议提示“会议已结束或会议号不存在”，请在官网下载最新版本入会。立即下载<https://zoom.us/download> If a message is displayed, indicating that the meeting has ended or the meeting ID does not exist, download the latest meeting client and try again.Download<https://zoom.us/download>
