本文档详细介绍了如何在UOS操作系统上手动配置AMD显卡的OpenCL环境，包括安装amdgpu-pro套件以及解决安装过程中遇到的兼容性问题。此外，还探讨了在UOS上为Intel核心显卡配置OpenCL环境的步骤，尽管最终由于门罗币挖矿算法不支持Intel核心显卡导致挖矿失败。整个过程涉及了OpenCL平台、设备、驱动和库的安装与配置，以及在不同设备间切换OpenCL环境的方法。

概述

AMD的显卡驱动虽然是开源了,但是对于OPENCL的编译那一套环境一直是自己在搞,貌似没有交给社区,所以要在UOS上配置基于AMD显卡的OPENCL环境,就不能简单的通过apt-get这样的命令直接安装搞定了,需要安装amdgpu-pro这一套,这个里面就包含了他显卡的全套东西(内核驱动,Xorg驱动,OpenGL,OpenCL库)等等.由于官网的amdgpu-pro只针对RHEL/ubuntu的长期维护版本提供支持,其余的Linux发行版就照顾不到了,不过基于debian的发行版还是可以白嫖的,不过就是得手工安装而不能一条命令自动安装了.
具体的可以参考这里:

https://linuxconfig.org/install-opencl-for-the-amdgpu-open-source-drivers-on-debian-and-ubuntu

安装过程

下载安装包
安装包我都是bing.com上面搜别人安装的文章给的连接 ,具体的自己去AMD网站用AMDGPU-Pro搜吧.
具体的版本我先后试了好几个版本,总是在内核驱动那里出问题,dkms编译不过去,要么就是我内核太高,5.4了,最后测试出来 https://drivers.amd.com/drivers/linux/amdgpu-pro-20.40-1147287-ubuntu-18.04.tar.xz 这个给18.04.5做的20.40版本可以正常安装.
做本地源
下载下来的包里面Packages文件都给你生成好了的,直接添加个源就好

actionchen@actionchen-PC:~/M-门罗币/neo$ cat /etc/apt/sources.list.d/demo.list 
deb [trusted=yes] file:/home/actionchen/M-门罗币/OPENCL-AMD/amdgpu-pro-20.40-1147287-ubuntu-18.04

我的就是这样,不要介意,我就是为了运行这个门罗币挖矿程序的OPENCL部分才想起来要在UOS上配置OPENCL环境的.
3. 直接开始安装需要的几个包

amdgpu-dkms
opencl-amdgpu-pro-icd
clinfo-amdgpu-pro
opencl-orca-amdgpu-pro-icd

安装这几个,他会自己去把其他依赖的包也给装上
安装完后/opt/amdgpu-pro/bin/clinfo 执行一下就可以看到有platform ,device信息了,Platform 包括支持的Opencl版本信息,device包括显卡的硬件配置信息了.
如果这时候运行程序还是报运行环境不对的话,再安装

ocl-icd-opencl-dev

这个包就对了,其实这个就是个opencl的loader(opencl-icd),前面也装了amd的loader,这里是系统的loader,loader会去/etc/下面扫描各种厂商信息的,如果不装这个,运行程序指定对应的loader也是可以的(反正就是把libopencl.so搞对就行)

最后就是直接运行你的opencl程序了,不过我这里有点杯具,这个门罗币的挖矿代码要求显存大于2GB,而我这个联想万年辣鸡笔记本配置的还是跟Intel核显没啥区别的 AMD 625 Mobile,刚好就是2G显存,真不知道这些笔记本厂商是为了啥,为了帮显卡厂商出掉些次品芯片吗 ?

关于一台机器多个opencl设备以及opencl的平台和设备之间关系的,可以参考下面这篇文章
https://streamhpc.com/blog/2015-08-14/opencl-basics-multiple-opencl-devices-with-the-icd/

综合起来就是:一个platform下面可以对一个多个设备,另外一个设备可以有多个Opnecl实现(例如苹果就比较牛叉,自己给设备实现一套而不是厂商实现) ,还有就是平台和设备的Opencl版本可以不一样.

下一步测试一下在UOS V20 (5.4kerne,非标准4.19内核)桌面上搞一把intel核显的Opencl环境,希望能搞起.

Intel核心新显卡的opencl配置

官网

安装方法参考

直接下载编译好的包安装就完全完事

cd neo

由于门罗币的挖矿算法就没说支持Intel核心显卡,所以用intel 核心显卡来挖矿就成为了不可能
https://github.com/tevador/RandomX

SChernykh is developing GPU mining code for RandomX. Benchmarks are included in the following repositories:

 - CUDA miner - NVIDIA GPUs. OpenCL miner - only for AMD Vega and AMD
 - Polaris GPUs (uses GCN machine code).

但是我还是尝试跑了一下,由于装上了intel 的Opencl环境,就有2个platform ,2个device ,运行挖矿程序的时候需要指定一下,门罗币这个挖矿程序还挺好,提供了命令行参数

actionchen@actionchen-PC:/tmp$ clinfo -l
Platform #0: Intel(R) OpenCL HD Graphics
 `-- Device #0: Intel(R) Graphics [0x9b41]
Platform #1: AMD Accelerated Parallel Processing
 `-- Device #0: Iceland

sudo ./xmrig -x 127.0.0.1:1089 -o xmr.f2pool.com:13531 -u 487oBceUnMnDAM9Fmk8UHu49g7SyKmdaXW3UUYVib7rmj8RbesS812BUQd9p2aJ2p8LYRs3raUsaxBR4NX1rxqRYV9CeSdb.001 -p x -k  --randomx-init=3  --opencl --opencl-platform=0 --no-cpu

估计是公司的防火墙做了加固,直接连鱼池是连不上的,直接reset了,所以挂个代理出去.

执行这个后运行到opencl的代码时候会报错退出.我也不知道是我安装的intel opencl二进制包的兼容性问题还是确实是因为挖矿程序生成的Opencl代码绑定了AMD显卡的特定接口.反正核显挖menluo币矿也失败了.

小结

笔记本辣鸡显卡和CPU核心显卡都没法挖ML(menluo)币,优化之路到此为止了.

另外,记录下怎么开1GB的大页面,按照挖矿软件官网运行那个脚本没用,开启方法是在系统启动的grub里给内核传参数 hugepagesz=1GB hugepages=3 ,这个1GB页面文件是否能开启成功和CPU还有关系
检查方法如下,如果硬件不支持估计也是开不了的:

cat /proc/cpuinfo | egrep -o pdpe1gb | head -n 1

另外,详细信息可以参考权威文档:
