进行系统reboot的python脚本，清除dmesg/message/mce/sel. 检查cpu，内存，pcie设备。做os reboot ,reboot回来后保存dmesg/message/mcelog/sel和cpu,内存，pcie设备信息。清除dmesg等，做os reset 一直循环200圈。最后打印运行的结果 和pass fail情况

以下是一个可能的实现，包括了对于清除和保存相关信息的函数以及主要的测试逻辑。为了方便测试，每次重启后会等待一段时间再进行检查，这个等待时间可以根据具体环境进行调整。

import os
import subprocess
import time

def clear_logs():
    subprocess.run(["dmesg", "-c"])
    subprocess.run(["echo", ">", "/var/log/messages"])
    subprocess.run(["echo", ">", "/var/log/mcelog"])
    subprocess.run(["echo", ">", "/var/log/audit/audit.log"])
    subprocess.run(["ipmitool", "sel", "clear"])

def save_logs(path):
    subprocess.run(["dmesg", "-T", "--level=err,warn,info,debug", "-s", "1000000", ">", os.path.join(path, "dmesg.log")])
    subprocess.run(["cp", "/var/log/messages", os.path.join(path, "messages.log")])
    subprocess.run(["cp", "/var/log/mcelog", os.path.join(path, "mcelog.log")])
    subprocess.run(["ipmitool", "sel", "elist", ">", os.path.join(path, "sel.log")])
    subprocess.run(["lscpu", ">", os.path.join(path, "cpu.log")])
    subprocess.run(["lspci", "-vvv", ">", os.path.join(path, "pcie.log")])

def check_system():
    # 检查CPU和内存
    # TODO: 实现检查CPU和内存的代码

    # 检查PCIe设备
    # TODO: 实现检查PCIe设备的代码

def reboot_and_check():
    clear_logs()
    check_system()
    subprocess.run(["reboot"])

    # 等待重启完成后再进行检查
    time.sleep(60)
    check_system()
    save_logs("reboot_logs")

def reset_and_check():
    clear_logs()
    check_system()
    subprocess.run(["systemctl", "reset", "cold"])

    # 等待重置完成后再进行检查
    time.sleep(60)
    check_system()
    save_logs("reset_logs")

def run_tests():
    num_pass = 0
    num_fail = 0
    for i in range(200):
        try:
            reboot_and_check()
            reset_and_check()
            num_pass += 1
            print(f"Iteration {i}: PASS")
        except Exception as e:
            num_fail += 1
            print(f"Iteration {i}: FAIL")
            print(str(e))

    print(f"Results: {num_pass} PASS, {num_fail} FAIL")

if __name__ == "__main__":
    run_tests()

需要注意的是，由于具体检查CPU、内存和PCIe设备的方法可能因系统而异，上述代码中并没有实现这些部分的代码。这部分需要根据具体的环境和需求进行编写。
