OpenJDK riscv-ports upstreaming 进展

皋陶

这是一则RISC-V社区快讯：

一、背景/上次简报

来自华为的BishengJDK-11（OpenJDK-11的下游开源项目）完成了 RV64G 的适配（含JIT）工作并在一周前BishengJDK王亚东向OpenJDK社区发了邮件，询问upstreaming的流程和要求。

PLCT实验室帮助完成了在 Hifive Unleashed 开发板的验证，获得了性能数据并公开同步到了RVI（RISC-V国际基金会）的社区。

赛昉科技（StarFive）支持了PLCT实验室RISC-V开发板。RVI大使傅炜为PLCT提供了 RISC-V OS 的支持。

二、目前收到的回应

虽然是假期，但是也收到了回复。目前 Edward Nevill 回复内容包含了：

第一点：2018年的时候有一个建立 port project 的尝试，当时的发起人 Andrew Haley  和支持者有 Palmer （现在在Google） 和 Andrew Haley（RedHat 的 Java Platform Lead Engineer）。有可能是希望能联系联系，毕竟前面已经有人提议但是没有填坑，看看是否能邀请一起填坑。

第二点：一些标准的申请流程。

回复是公开的邮件列表，为了方便查看我将邮件内容贴在这里：

Hi,

In order to progress this a riscv-port project will need to be created. There was an initial attempt to get a riscv-port project started in Feb. 2018 (seehttps://mail.openjdk.java.net/pipermail/porters-dev/2018-February/thread.html).

The process for creation of a new OpenJDK project is described at http://openjdk.java.net/projects/#new-project

In accordance with the OpenJDK bylaws the initial discussion should be sent to the general discussion list, discuss.at.openjdk.dot.java.dot.net with the subject line "Call for Discussion: New Project: riscv-port".

However, it may be best to have an initial discussion here on porters-dev before submitting the formal Call for Discussion on discuss.

The project will need a project lead who must be a Contributor and must be sponsored by a Group Lead. Although technically any Group Lead could sponsor this project, in practice it should be the Group Lead of the porters project, Dalibor Topic （注：这是oracle负责 jdk-11 的principal product manager [d]）.

All the best,

Ed.

Hi,

   We implemented a RV64G port of OpenJDK11u(TemplateInterpreter, C1 and C2) and open source to https://gitee.com/openeuler/bishengjdk-11/tree/risc-v/ . Would the community like to help us to create a project? And then we can promote it stable with the community.
