@Rebel-Rider Thank you. Just odered.

The wiki is still WIP but theres now a chinese wiki aswell

@mainbord
At present, the mainline kernel EDP interface is not supported. The CM5-LAPTOP configuration has been submitted for mainline review and should be released soon.

@happyday
默认是DHCP自动获取的，你可以改为固定IP，网上很多资料。百度一下就能解决。

只找到了这个

@santu
重启和重新上电以后运行如下命令发出来

@markerrors 我也遇到了，然后解决办法是，把wifi密码的认证模式从wpa3转为wpa2就可以了。

just use flatpak

there are many app on flathub with arch64 support.

@plumlis The performance is perfect, there is absolutely no issues present, on glmark2 with Xorg all tests are running between 1400-1500 fps(this is heavily window system dependent so take it with a HEAVY grain of salt when making comparisons!!!). I have much better battery life as well. Everything is much better than my previous laptop.

My harddrive I used to compile armbian with 6.1 broke, all though If you are willing I could send patches, the issue with my specific setup is that it highly depends on out of tree patches. Perhaps I might be able to upstream some of it to the coolpi armbian github? Although the issue with that is that I am locked out of my google accounts currently.

If you are willing to put in (not too much) effort I could send you some patches to apply to the official Coolpi Armbian repository, note that it requires a x86_64 Intel/AMD machine with Linux and Docker(If you dont use Ubuntu).

我是做SPI设备驱动，但是默认情况下Master端不打开DMA，我也测试了。如何设置为master mode呢？

@28717885
参考如下文档

@plumlis
This method has been tried before, and as you said, the actual effect can be seen in the Ubuntu system. However, if it is a system with kylin and uos, it must always run in performance mode to run smoothly. We will re evaluate whether to update to the existing kernel configuration. Thank you for your suggestion.

@plumlis
The testing before AX210 was problematic. The most basic BT cannot recognize it, it seems that the firmware version of WIFI is incorrect.

@plumlis
FFmpeg can be changed to a native package. Or using the Chromium browser, the decoding issue of this player has been bothering us for a long time. Take some time later to focus on solving it.

@plumlis
The battery of the RTC connector has a spacing of 0.8mm. From the current phenomenon, it is not that the hardware RTC cannot save time, but rather that the hardware RTC time has not been synchronized with the system. So adding this battery won't make any changes.

以下结果来自大模型：
在Linux中，可以通过多种方式将应用程序绑定到特定的CPU上执行，这样可以减少上下文切换，提高性能。以下是一些常用的方法：

使用 taskset 命令:
taskset 命令可以用来限制一个进程只能使用指定的CPU或CPU集合。使用以下命令启动一个应用程序并将其绑定到特定的CPU：

taskset -c 0,1,2 my_application
这将允许 my_application 只在CPU 0、1和2上运行。

使用 nice 和 renice 命令:
nice 命令可以在启动时设置一个进程的调度优先级，而 renice 可以更改一个已经运行的进程的优先级。这不是直接绑定CPU，但可以影响进程的调度。

nice -n 10 --adjustment=+5 my_application
使用 cgroups:
cgroups（控制组）是一种Linux内核特性，它可以将进程分组，并为这些组应用特定的系统资源限制。通过 cgroups，你可以将进程绑定到特定的CPU。

首先，创建一个新的cgroup：

sudo cgcreate -g cpuset:/my_group
然后，添加CPU到这个cgroup：

sudo echo 0-2 > /sys/fs/cgroup/cpuset/my_group/cpuset.cpus
接下来，将应用程序添加到这个cgroup：

sudo cgclassify -g cpuset:my_group my_application
使用 numactl 命令:
numactl 命令用于控制NUMA（非统一内存访问）系统中的CPU和内存亲和性。它也可以用于将进程绑定到特定的CPU。

numactl --physcpubind=0,1,2 my_application
使用 sched_setaffinity 系统调用:
在编程时，可以使用 sched_setaffinity 系统调用来设置进程的CPU亲和性。这需要在编写应用程序时进行设置。

使用 top 或 htop 工具:
在使用 top 或 htop 时，可以通过交互式命令将进程绑定到特定的CPU。在 htop 中，可以使用 ~ 键来切换“CPU绑定”模式，然后选择CPU。

编辑 /etc/security/limits.conf:
对于基于System V的进程控制，可以在 limits.conf 文件中设置CPU亲和性。

请注意，绑定CPU可能会影响系统的调度器性能，并且不是所有的应用程序都会从CPU绑定中受益。在进行CPU绑定之前，应该仔细考虑应用程序的需求和系统的整体性能。

@george
Nice, I'll waitting for good news.

@yaitoro
Yes, this is the official store address.

@happyday cpu内核运行有上下文，颗粒调度，你要独占一个核，也可以绑定操作

@markerrors 有完整可复现过程？

@traceback
I found the solution in github:
FirstSecond

@plumlis
对，就是这个地方，自行修改就好了。

@happyday
需要从github下载代码到机器，然后修改，编译，替换。

@george
插拔了几次 也清理了一下 还是一样的结果 但是不会频繁的输出i2c read err 就是HDMI还是没有输出 只是开机画面有 dmesg 变成这个了

我这个是V10的核心板 底板是最近才买的新底板

@Momo-0 Thank for your reply.
I think the point is pcie 3.0 /4.0
maybe pcie 3.0 version nvme ssd should be okay.

How to update to 6.x kernel?
I tried to compile this
https://github.com/yanyitech/coolpi-kernel/tree/linux-6.1-stan-rkr1
Next I install kernel according to the instructions
https://forum.cool-pi.com/topic/514/cool-pi-cm5-laptop-linux-quick-start-guide

5.10 installed successfully but after install 6.1 it's does not booted

@george
Could you help? does it give this error when connecting?
[ 8.515533] dw-mipi-dsi2 fde20000.dsi: [drm:dw_mipi_dsi2_bind] ERROR Failed to find panel or bridge: -517

@Twsuts-0 备份还原搞定了吗
