 To develop eBPF programs, you need to install the following software and tools:
 
-- Linux kernel: Since eBPF is a kernel technology, you need to have a relatively new version of the Linux kernel (minimium version 4.8 and above, suggested version is 5.15+ or 6.2+) to support eBPF functionality.

   - If possible, install a new version of Ubuntu (e.g. 23.10) would be better. 
 - LLVM and Clang: These tools are used to compile eBPF programs. Installing the latest version of LLVM and Clang ensures that you get the best eBPF support.

 bpftime 可以类似 Kernel 中的 Uprobe 那样，自动将 eBPF 运行时注入到用户空间进程中，无需修改用户空间进程的代码，也无需进行重启进程即可使用。对于 ubpf 和 rbpf 而言，它们依然需要手动编写胶水代码和其他用户空间程序进行集成，相对来说限制了它们的使用场景。在某些场景下，bpftime 可能能作为 kernel eBPF 的一种替代方案，它也不依赖于具体内核版本或 Linux 平台，可以在其他平台上运行。
