具体地，可以通过禁止使用待隔离出错地址对应的内存区域来实现隔离。Specifically, the isolation can be implemented by prohibiting the use of the memory area corresponding to the error address to be isolated.
本发明实施例可以通过IMS(Intelligent Memory Surveillance，智能内存监控)来实现：The embodiment of the present invention can be realized through IMS (Intelligent Memory Surveillance, intelligent memory monitoring):
(1)在/home/test/iMSLinux目录下键入命令：insmod iMSDrv.ko；(1) Type the command in the /home/test/iMSLinux directory: insmod iMSDrv.ko;
在该步骤中，在操作系统中，安装IMS的驱动。In this step, the driver of the IMS is installed in the operating system.
(2)运行IMS应用程序。(2) Run the IMS application program.
在/home/test/iMSLinux目录下键入以下命令：Type the following command in the /home/test/iMSLinux directory:
./iMSApp–threshold n–print-mcelog file-interval n–nosign./iMSApp –threshold n –print-mcelog file-interval n –nosign
上述命令行参数定义如下：The above command line parameters are defined as follows:
-threshold n 设置门限值为n；-threshold n set the threshold value to n;
-print 输出内存错误对应的出错地址；-print Output the error address corresponding to the memory error;
-mcelog file 设置日志文件为mce log文件，缺省的文件是/var/log/mcelog；-mcelog file Set the log file to mce log file, the default file is /var/log/mcelog;
-interval n 设置检查mce log文件的时间间隔，单位为秒，缺省值为30；-interval n Set the time interval for checking the mce log file, in seconds, the default value is 30;
-nosign enable iMS的实时监控和保护OS应用程序；若无此参数iMSApp不工作。-nosign enable iMS real-time monitoring and protection OS application; without this parameter iMSApp will not work.
通过该命令，IMS可以设置门限值，设置访问的日志文件，设置访问日志文件的周期，输出出错地址。Through this command, the IMS can set the threshold, set the log file for access, set the period for accessing the log file, and output the error address.
具体地，利用iMS能够依据日志文件，对出错地址进行强化侦测，确认该出错地址是待隔离出错地址后，随即对其进行临时性隔离，这样可以使得操作系统的ECC报错逐步减少，并且不会影响系统的正常运行。为保证系统重启后，曾经出现过的内存错误不再重复出现，操作系统中的iMS会把待隔离出错地址传递给BIOS级的iMS，在下次系统重启时，在BIOS阶段，通过BIOS级的iMS对待隔离出错地址进行隔离，将这些待隔离出错地址从系统可用的内存区域中永久屏蔽掉。Specifically, the use of iMS can strengthen the detection of error addresses based on log files, and after confirming that the error address is an error address to be isolated, it can be temporarily isolated, which can gradually reduce the number of ECC errors reported by the operating system and prevent It will affect the normal operation of the system. In order to ensure that the previous memory errors will not recur after the system is restarted, the iMS in the operating system will pass the address of the error to be isolated to the BIOS-level iMS. When the system restarts next time, at the BIOS stage, the BIOS-level iMS will Isolate the error addresses to be isolated, and permanently shield these error addresses to be isolated from the available memory area of the system.
其中，IMS按照到操作系统并处于Enable以后，全部自动后台运行，不必用户任何操作干预。Among them, IMS runs automatically in the background according to the operating system and after it is enabled, without any user intervention.
