Install the script:
yay -S linux-wifi-hotspot
Create the wifi via:
systemctl enable --now create_ap

使用rockylinux:9的容器镜像创建一个容器实例:
sudo docker run -it rockylinux:9 bash
在容器实例中，运行以下命令准备内核的编译环境:
sed -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g' -i.bak /etc/yum.repos.d/rocky-extras.repo /etc/yum.repos.d/rocky.repo

useradd -m mock
新建一个终端，在该终端上将运行中且已做上述修改的容器实例提交为容器镜像以便下次使用:
[root@dellnew ~]# docker ps

使用上节创建的编译镜像编译内核:
[root@text ~]# docker run --name=testrocky -v /root/buildout:/buildout -it buidrockykernel:latest /bin/bash
[root@fa4d8f532c21 /]# cp /buildout/kernel-5.15.113-200.el9.src.rpm /home/mock/
[root@fa4d8f532c21 /]# su - mock
[mock@fa4d8f532c21 ~]$ rpm -Uvh kernel-5.15.113-200.el9.src.rpm
[mock@fa4d8f532c21 ~]$ cd rpmbuild/SPECS/
[mock@fa4d8f532c21 SPECS]$ time rpmbuild -ba kernel.spec 2>&1 | tee build.log
编译出的内核rpm包位于/home/mock/rpmbuild下，可以通过find /home/mock/rpmbuild | grep rpm$命令找到。
Create a docker instance:
sudo docker run -it rockylinux:9 bash
In docker, run:
sed -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g' -i.bak /etc/yum.repos.d/rocky-extras.repo /etc/yum.repos.d/rocky.repo

useradd -m mock
Then in host machine, do :
[root@dellnew ~]# docker ps

Next time using this latest commited kernel you could directly build kernel src.
Build via following command:
[root@text ~]# docker run --name=testrocky -v /root/buildout:/buildout -it buidrockykernel:latest /bin/bash
[root@fa4d8f532c21 /]# cp /buildout/kernel-5.15.113-200.el9.src.rpm /home/mock/

Enable perftools building, I think it failed because of the libebpf is too new comparing to 5.15.113 kernel. so changes to kerner’s tools/lib/bpf version’s libebpf-devel package for building.
