[PATCH] Memory model: Fix the memory model issues for Linux kernel
by Hanjun Guo 24 Sep '22

24 Sep '22

From: Jonas Oberhauser <jonas.oberhauser(a)huawei.com> This is the update and fixes for memory model, simplify the model by removing redundancies, making semantics of seq-cst explicit, making ppo a subset of po, making ppo locally computable, as well as eliminating several spurious bugs in qspinlock and litmus tests, and ensuring correct compilation to the official power model. These issues were detected by Jonas Oberhauser, Viktor Vafeiadis, and the authors of "Verifying and Optimizing Compact NUMA-Aware Locks on Weak Memory Models", and the solutions are proposed by Jonas Oberhauser and Viktor Vafeiadis.

[PATCH for openEuler 22.09] Memory model: Fix the memory model issues for Linux kernel
by Hanjun Guo 24 Sep '22

24 Sep '22

From: Jonas Oberhauser <jonas.oberhauser(a)huawei.com> This the update and fixes for memory model, simplify the model by removing redundancies, making semantics of seq-cst explicit, making ppo a subset of po, making ppo locally computable, as well as eliminating several spurious bugs in qspinlock and litmus tests, and ensuring correct compilation to the official power model. These issues were detected by Jonas Oberhauser, Viktor Vafeiadis, and the authors of "Verifying and Optimizing Compact NUMA-Aware Locks on Weak Memory Models", and the solutions are proposed by Jonas Oberhauser and Viktor Vafeiadis.

Hi all:近期版本编译中发现有不少软件包配置的第三方依赖镜像源（主要是maven仓）为： mirrors.huaweicloud.com；  使用该地址容易出现包下载失败问题，主要原因是该地址并发受限；华为云镜像站建议使用CDN地址： repo.huaweicloud.com,  以maven仓为例，配置如下： ------------------------------------------------------------------------------------------------- Hi all： During the compilation of the latest version, the third-party image source (mainly the Maven repository) configured for many software packages is mirrors.huaweicloud.com. When this address is used, packet download may fail. The main reason is that the concurrent access of this address is limited. We are advised to use the CDN address repo.huaweicloud.com. The following uses the Maven repository as an example. The configuration is as follows: <mirror>     <id>huaweicloud</id>     <mirrorOf>*</mirrorOf>     <url>https://repo.huaweicloud.com/repository/maven/</url> </mirror> best regards Infra - George

Hi All, I'm Bo Zhao, so apologized that I had to step down as DB SIG maintainer today. I worked in openEuler DB SIG for 1 year. SIG partners worked together and made so many great contributions in openEuler. I'm so happy that I can work with you guys. That's an unforgettable time in life. I will post a PR for the roles removing. Thank you all about your helps and hard work. openEuler will be better and successful. Best Regards, Bo Zhao
