ArchLinux 的jdk版本已经14了，但是为了损伤CPU, 所以将jdk repo 更新一下，得到最新的jdk 源码

通过

1
sh configure --with-jvm-features=zgc

的方式开始编译三板斧的第一步

然后通过

1
make CONF=linux-x86_64-server-release images

编译jdk

最后在build/linux-x86_64-server-release/jdk 下就是编译好的jdk ，又一次对CPU进行了损伤

添加如下代码做一个对ZGC的hello

1

5
public class HelloZGC{
    public static void main (String [] args) {
        System.out.println("Say hello to new low pause GC - ZGC!");
    }
}

这时候就可以通过

1
java -XX:+UnlockExperimentalVMOptions -XX:+UseZGC -Xlog:gc* HelloZGC.java

直接运行了

在zsh 环境下-Xlog:gc * 需要特殊处理，所以使用zsh 的情况下，修改一下-Xlog:gc 的格式

gitrepo/jdk/build/linux-x86_64-server-release/jdk/bin/java -XX:+UnlockExperimentalVMOptions -XX:+UseZGC -Xlog:gc*:mylog.log HelloZGC.java

基本可以得到下面的输出

需要注意的是，因为ZGC还在不断的发展(不然也不需要通过-XX:+UnlockExperimentalVMOptions 的方式才能打开了), 所以在做实验的时候，参考的文章可以看，但是不一定是和最新的版本

比如看的文章是在jdk 11 时期写的，但是现在的新版本是jdk 14 , 而自己构建的是jdk 15 , 这之间ZGC发生了很多变更，比如在flags 上的变更就是因为版本迭代

ZGC 的内存大小是2M x * 的方式，目前32M 的最小的堆大小，8M 的小堆还需要ZGC团队在jep 上开展研发(本人在这方面就是一个看客)

最后为什么ZGC可以支持4T的堆，可以通过下面这张图来看到

因为一段时间基于GCC 10 不能正确构建jdk , 所以不能了解ZGC是否已经支持8M的小堆，今天基于jdk 主干，成功通过GCC 10 进行构建
再次测试8M的小堆，发现正常输出，而不是出现OOM

在目前的jdk 11, jdk 14 上的测试还是会OOM, 而jdk 16和主干代码都可以支持8M的小堆
按照https://wiki.openjdk.java.net/display/zgc/Main的描述，此功能是在jdk 14 上提供的支持

jdk 11 暂时还不可用，可能需要等待后期他们讲代码backport 到jdk 11 上来
