Try Steps
Replace the repository for speedup:
sed -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g' -i.bak /etc/yum.repos.d/rocky-extras.repo /etc/yum.repos.d/rocky.repo
yum makecache
Install docker:
dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
# replace all of the `download.docker.com` into `https://mirrors.ustc.edu.cn/docker-ce`
yum makecache
yum install -y docker-ce
systemctl enable docker
systemctl start docker
Pull rockylinux9 and prepare building environment via:
docker pull rockylinux:9
docker run -it -v /root/source:/source rockylinux:9 /bin/bash
sed -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g' -i.bak /etc/yum.repos.d/rocky-extras.repo /etc/yum.repos.d/rocky.repo

Create docker instance:
docker run -it -v /root/source:/source rockylinux:9 /bin/bash
In docker, prepare for building kernel:
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

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.
