能否做个loong64版本的blas-openblas并弄进上游？arch上游目前仅有x86_64版的。缺省的blas性能很低，只有openblas库性能的1/10左右。openblas数学库用的是非常广的。

还有openmotif，非常基础的Linux图形库软件，用的也非常广。龙芯的loongnix系统有这个软件，arch上游目前同样仅有x86_64版的。

§龙芯是OpenBLAS开源社区成员，向OpenBLAS累计提交4W+行代码,是该社区LA架构的主要维护者。

§OpenBLAS社区从0.3.18版本开始支持LoongArch架构，核心接口均已完成汇编优化,性能提升明显。

§龙芯基本线性代数库很好地支撑了linpack 性能测试以及LAPACK和SCALAPACK等计算库。

seeseesee 今天系统更新，看到已经有了系统级的blas-openblas，不错。安装时有点小问题：

把链接文件/usr/lib/libopenblas.so.0改名后就可以安装。安装后用python测试了一下：“Eigendecomposition of a 2048x2048 matrix in 11.02 s.” 同样测试在loongnix系统里用openblas测试是6.6秒左右。编译源码安装的话，loongnix系统仍没问题，Arch Linux上python多线程测试只能利用一个线程且长时间无反应。

在3A6000+7A2000集显上也遇到这个黑屏问题，照着做成功安装上了！！！

现在发现几个问题：

1、应用程序不显示中文标题

2、smplayer 播放 x264 视频时 mpv 崩溃：

PANIC: unprotected error in call to Lua API (8)

PANIC: unprotected error in call to Lua API (10)

（smplayer选择mplayer播放引擎则可正常播放）

3、计算机空闲进入睡眠机器会进入关机状态，第一次按电源启动起不动，关掉再次启动正常

1. 请求支持aur源中的rustdesk包（开源远程桌面，向日葵的替代）

2. 请求考虑支持Archlinuxcn中的所有由源码构建的包，这些包经典且实用。（是否可和Archlinuxcn的人合作？尽量使cn源中能构建过的支持loong64）

rustdesk 可以试试用 yay rustdesk 命令直接安装

装不了

vans_fans 说的不是龙芯向OpenBLAS社区贡献的问题，说的是现在的LoongArch架构archlinux没有系统级的openblas的问题啊，而x86架构的archlinux是有的。

尝试使用Live-CD安装了带Gnome+GDM的archlinux,但是重启之后进入桌面一直黑屏,KED也是一样.但是安装mate+lightdm就正常, 给安装的Gnome的archlinux安装mate+lightdm, 可以正常进mate, 但是没法进Gnome, 这个是不是没有独显导致的, 我这边的硬件用的是3A6000+7A2000, 用的集显, 没装独显.

CastleKin
是这个原因，独显正常

yetist 未来集显有可能获得支持吗？

最新的 2023.12.30 的 livecd 修复了使用集显时，安装程序部分界面变黑的问题，可以测试一下。
https://mirrors.wsyu.edu.cn/loongarch/archlinux/iso/2023.12.30/

3A6000现在支持怎么样呢？

买了挚科（ZHIKE）ZKL360-TF主机3A6000CPU，想试试，看到介绍又说的是针对的3A5000，很好奇3A6000表现怎么样呢？会不会bug多的没法用，后面应该要把3A6000作为支持重点之一吧，啥时候正式把3A6000纳入呢？

wvb 3A6000跟3A5000指令集是一样的，而且龙芯周边的硬件基本就那几样，所以驱动一般都算有了。总结下来就是可以直接用的

wvb 我买的机器和你一样，今天才装上arch linux，先去github上下载固件并更新，然后到这里找最新的archlinux live cd，可以装成功的。

啥时候支持下主板自带的集显，不然安装后桌面白屏，只能看到个鼠标箭头

seeseesee 重启后又试了一次，在新内核6.7.0-6下出错了。。。，不知道哪里的问题：
