Description

一种系统的维护进程运行方法及装置Method and device for running maintenance process of system 技术领域Technical field
本文涉及但不限于计算机操作系统技术领域，尤其涉及一种系统的维护进程运行方法及装置。This document relates to, but is not limited to, the field of computer operating system technology, and in particular, to a system maintenance process running method and device.
背景技术Background technique
承载着关键业务的操作系统通常也承载着巨大的业务压力和负荷，这种情况下，一方面对系统的可靠性是一种严峻的考验，另一方面对系统的可维护性也有越来越高的要求。实际应用场景中，系统故障难以避免，但对于系统故障的分析定位却一直是困扰系统用户和系统开发人员的一大难题，主要原因还在于系统故障时的关键信息(如系统日志等)无法获取，从而无法判断系统的具体故障。Operating systems that carry critical services often carry huge business pressures and loads. In this case, on the one hand, the reliability of the system is a severe test, on the other hand, the maintainability of the system is also increasing. High requirements. In actual application scenarios, system faults are difficult to avoid, but the analysis and location of system faults has always been a major problem for system users and system developers. The main reason is that critical information (such as system logs) cannot be obtained during system failure. Therefore, it is impossible to judge the specific failure of the system.
系统的维护进程对于判断系统的故障及对系统故障的分析有着至关重要的作用。例如，对于系统的日志记录进程，系统日志由日志记录进程负责记录，日志记录进程通过写磁盘来记录日志，但这样的日志记录方式在系统出现异常情况时，无法保证日志能可靠写入磁盘。其主要原因包括：1)日志记录进程写磁盘操作需要经过相当复杂的流程，以Linux操作系统为例，可能涉及缓存、内核中的块设备层、IO(输入输出，本文简称IO)调度层、SCSI层、以及磁盘驱动等模块的处理过程，期间可能会因为各种原因导致阻塞，比如：内存紧张导致内核流程中分配内存时阻塞，进而导致写磁盘操作阻塞；或者系统IO繁忙导致IO阻塞，进而导致写磁盘操作阻塞；2)日志记录进程写磁盘操作依赖于系统中进程调度，如果进程调度出现异常，此时可能无法调度负责记录日志的用户进程，进而也就无法记录日志。导致进程调度出现异常的情况也比较多，比如：当系统CPU负荷过重时、或当前CPU上有更高优先级的进程持续占用CPU时，都可能导致负责记录日志的日志记录进程无法得到调度或产生调度延迟；另外，对于系统的监控进程针对操作系统运行状态的监控，如软件看门狗，通过软件之间的交互来达到监控系统运 行状态的目的，其主要缺点在于：由于软件受进程调度、进程间通信、系统资源等因素的影响，其可靠性无法得到保证；还有，在对于系统运行状态的监控中，也可以使用硬件看门狗进行监控，但其需要额外增加一个硬件设备，适用范围有限，不具备通用性。The maintenance process of the system plays a crucial role in judging the failure of the system and the analysis of the system failure. For example, for the system's logging process, the system log is recorded by the logging process. The logging process records the log by writing to the disk. However, when the system is abnormal, the log cannot be reliably written to the disk. The main reasons include: 1) The logging process requires a fairly complicated process for writing disk operations. Taking the Linux operating system as an example, it may involve caching, block device layers in the kernel, and IO (input and output, referred to as IO) scheduling layer. The processing of modules such as the SCSI layer and the disk drive may be blocked for various reasons. For example, if the memory is tight, the memory is blocked when the memory is allocated in the kernel process, and the write disk operation is blocked; or the system IO is busy, causing IO blocking. In turn, the write disk operation is blocked. 2) The log record process write disk operation depends on the process schedule in the system. If the process schedule is abnormal, the user process responsible for logging may not be scheduled at this time, and thus the log cannot be recorded. There are many exceptions that cause the process to be dispatched. For example, when the CPU load of the system is too heavy, or when a process with a higher priority on the current CPU continues to occupy the CPU, the log record process responsible for logging may not be scheduled. Or generate scheduling delay; in addition, for the monitoring process of the system for the monitoring of the operating state of the operating system, such as software watchdog, through the interaction between software to achieve monitoring system operation The main disadvantage of the purpose of the row state is that the reliability of the software cannot be guaranteed due to factors such as process scheduling, inter-process communication, system resources, etc. Also, hardware can be used in monitoring the operating state of the system. The watchdog is monitored, but it requires an additional hardware device that is limited in scope and not universal.

S202：为所述专用CPU核分配专用的CPU内存资源，同样地，将分配的CPU内存资源与原操作系统进行隔离，保证原操作系统不会管理和使用该分配的物理内存，防止原操作系统内存异常对专用CPU核上运行的任务造成影响；S202: Allocating a dedicated CPU memory resource to the dedicated CPU core, and similarly, isolating the allocated CPU memory resources from the original operating system to ensure that the original operating system does not manage and use the allocated physical memory, thereby preventing the original operating system. Memory exceptions affect the tasks running on the dedicated CPU core;
S203：为所述专用CPU核与原操作系统之间进行通信和数据交互分配专用的数据硬件资源；要在专用CPU核上实现对原操作系统的监控或对原操作系统的日志记录，需要了解原操作系统的运行状态，具体可以通过共享内存的方式实现，这就需要为此分配专用的内存资源，该部分内存资源对原操作系统和专用CPU核都是可见的，为可靠起见，还可以控制该部分内存的访问权限，如：使原操作系统对该部分仅有可写权限，使专用CPU对该部分内存仅有可读权限等；S203: Allocating dedicated data hardware resources for communication and data interaction between the dedicated CPU core and the original operating system; to implement monitoring of the original operating system or logging of the original operating system on the dedicated CPU core, it is necessary to understand The running state of the original operating system can be realized by means of shared memory. This requires a dedicated memory resource to be allocated for this purpose. The memory resources of the original operating system are visible to the original operating system and the dedicated CPU core. For the sake of reliability, Control the access rights of the part of the memory, such as: the original operating system has only writeable rights to the part, so that the dedicated CPU has only readable rights to the part of the memory;

需要说明的是，所述运行环境模块需要完成的相应功能包括：初始化专 用CPU核相关的硬件环境；加载对应的系统的维护进程；从指定存储介质中读取系统的维护进程对应的程序，将其加载到为专用CPU核预先分配的内存中；跳转到系统的维护进程对应的程序入口开始执行。初始化专用CPU核相关的硬件环境包括：初始化CPU相关的寄存器，使专用CPU核运行于实模式下；初始化CPU的IDTR寄存器，使其指向BIOS初始化的中断描述符表；如此，可以使该CPU通过中断的方式直接利用BIOS的提供的功能(因为中断服务程序在BIOS中实现)，比如磁盘访问的功能；完成内存相关的初始化。比如，为专用CPU核预留的物理内存区域的初始化。It should be noted that the corresponding functions that the running environment module needs to complete include: initializing Using the hardware environment related to the CPU core; loading the maintenance process of the corresponding system; reading the program corresponding to the maintenance process of the system from the specified storage medium, loading it into the memory allocated for the dedicated CPU core; jumping to the system The program entry corresponding to the maintenance process starts execution. The hardware environment related to initializing the dedicated CPU core includes: initializing the CPU-related registers, causing the dedicated CPU core to run in real mode; initializing the CPU's IDTR register to point to the BIOS-initiated interrupt descriptor table; thus, the CPU can be passed The way of interrupting directly utilizes the functions provided by the BIOS (because the interrupt service routine is implemented in the BIOS), such as the function of disk access; complete memory-related initialization. For example, initialization of a physical memory area reserved for a dedicated CPU core.
如图4所示，步骤S102将所述分配的硬件资源与原操作系统隔离包括以下步骤：As shown in FIG. 4, step S102 isolates the allocated hardware resources from the original operating system, including the following steps:
S401：将分配的专用CPU核从原操作系统的进程调度模块中剔除；保证原操作系统中的进程不会被调度到该专用CPU核上。S401: The allocated dedicated CPU core is removed from the process scheduling module of the original operating system; ensuring that processes in the original operating system are not scheduled to the dedicated CPU core.
S402：将所述专用CPU核从中断路由模块中剔除；保证来自外部的外设中断不会被路由到该专用CPU上。S402: The dedicated CPU core is removed from the interrupt routing module; ensuring that external peripheral interrupts are not routed to the dedicated CPU.
S403：设置所述专用CPU核对应的核间中断掩码位；避免来自其它CPU的核间中断被发送到该CPU上。S403: Set an inter-core interrupt mask bit corresponding to the dedicated CPU core; prevent an inter-core interrupt from another CPU from being sent to the CPU.

上述将分配的硬件资源与原操作系统隔离的实现保证了专用CPU核使用的硬件资源的独立性。The above-described implementation of isolating the allocated hardware resources from the original operating system ensures the independence of the hardware resources used by the dedicated CPU core.
可选地，在实际应用中，所述系统的维护进程包括：系统的日志记录进程和/或系统的监控进程；所述步骤S101为系统的维护进程分配对应的硬件资源包括：为所述日志记录进程和/或监控进程分配对应的硬件资源；所述步骤S103控制所述维护进程在所述硬件资源内运行包括：控制所述日志记录进程和/或监控进程在所述对应的硬件资源内运行。Optionally, in a practical application, the maintenance process of the system includes: a logging process of the system and/or a monitoring process of the system; and the step S101 is to allocate corresponding hardware resources to the maintenance process of the system, including: The recording process and/or the monitoring process allocate corresponding hardware resources; the step S103 controlling the maintenance process to run in the hardware resource comprises: controlling the logging process and/or monitoring process in the corresponding hardware resource run.
当所述系统的维护进程为系统的日志记录进程时，如图5所示，所述控 制所述日志记录进程在所述对应的硬件资源内运行包括：When the maintenance process of the system is a logging process of the system, as shown in FIG. 5, the control is performed. The logging process running within the corresponding hardware resource includes:
S501：原操作系统将日志信息记录于专用的数据硬件资源中；S501: The original operating system records the log information in a dedicated data hardware resource;
S502：原操作系统将所述数据硬件资源中的日志信息以固定的格式写入为原操作系统和对应的专用CPU核之间通信所保留的数据硬件资源中的对应位置；S502: The original operating system writes the log information in the data hardware resource in a fixed format into a corresponding position in a data hardware resource reserved by communication between the original operating system and the corresponding dedicated CPU core;
S503：从为原操作系统和专用CPU核之间通信所保留的数据硬件资源中的对应位置中读取相应的数据硬件资源的日志信息；S503: Read log information of a corresponding data hardware resource from a corresponding position in a data hardware resource reserved for communication between the original operating system and the dedicated CPU core;
S504：调用磁盘操作接口将相应的数据硬件资源中的日志信息直接写入指定的磁盘扇区范围中。可选地，调用BIOS提供的磁盘操作接口将相应数据硬件资源中的信息直接写入指定的磁盘扇区范围中。BIOS提供的接口通常为中断接口，比如INT 13H。S504: Calling the disk operation interface to directly write the log information in the corresponding data hardware resource to the specified disk sector range. Optionally, the disk operation interface provided by the BIOS is called to directly write information in the corresponding data hardware resource into the specified disk sector range. The interface provided by the BIOS is usually an interrupt interface, such as the INT 13H.
当所述系统的维护进程为系统的监控进程时，如图6所示，控制所述监控进程在所述对应的硬件资源内运行包括：When the maintenance process of the system is a monitoring process of the system, as shown in FIG. 6, controlling the monitoring process to run in the corresponding hardware resource includes:
S601：向为原操作系统和专用CPU核之间通信所保留的数据硬件资源中的对应位置写入监控信息；所述监控信息可以为心跳信息；S601: Write monitoring information to a corresponding location in a data hardware resource reserved for communication between the original operating system and the dedicated CPU core; the monitoring information may be heartbeat information;
S602：从为原操作系统和专用CPU核之间通信所保留的数据硬件资源中的对应位置读取所述监控信息；S602: Read the monitoring information from a corresponding position in a data hardware resource reserved for communication between the original operating system and the dedicated CPU core;
S603：根据所述监控信息的更新情况判断原操作系统是否正常运行。例如，当所述监控信息为心跳信息时，系统监控程序中判断心跳信息是否更新，如果指定周期内，心跳信息一直未更新，则表明原操作系统已发生异常；如果指定周期内，心跳信息存在更新，原操作系统正常。当系统监控程序监控到原操作系统发生异常，则发起相应的操作，比如：直接复位硬件；或者先搜集当前的内存镜像信息用于后续的故障分析定位，然后再进行复位。S603: Determine whether the original operating system runs normally according to the update status of the monitoring information. For example, when the monitoring information is heartbeat information, the system monitoring program determines whether the heartbeat information is updated. If the heartbeat information is not updated within the specified period, it indicates that the original operating system has an abnormality; if the heartbeat information exists within the specified period Update, the original operating system is normal. When the system monitor monitors the abnormality of the original operating system, it initiates corresponding operations, such as: directly resetting the hardware; or collecting the current memory mirror information for subsequent fault analysis and positioning, and then resetting.
需要说明的是，在上述运行环境模块需要为系统的维护进程提供运行环境时，针对上述日志记录进程及系统监控进程提供对应的运行环境，需要在实模式中运行，以便于使用BIOS接口，其实现需要独立于原操作系统，具体的实现方式可以有多种选择，包括但不局限于以下几种： It should be noted that, when the operating environment module needs to provide a running environment for the maintenance process of the system, the corresponding running environment is provided for the foregoing logging process and the system monitoring process, and needs to be run in the real mode, so as to use the BIOS interface. The implementation needs to be independent of the original operating system. There are many options for the specific implementation, including but not limited to the following:
1)完全重新实现，不提供操作系统环境。由于专用CPU运行于实模式中，同时其实现的功能简单、独立，可以考虑将日志记录进程和系统的监控进程实现的功能串行化，并使用固定内存的方式，如此，可以考虑直接编写相应的代码，实现硬件初始化、日志记录进程和系统的监控进程加载及运行的功能，而不考虑实现进程调度、内存管理、输入输出等复杂的功能；1) Completely re-implemented, no operating system environment is provided. Since the dedicated CPU runs in real mode and its functions are simple and independent, you can consider serializing the functions of the logging process and the monitoring process of the system, and using fixed memory. So, you can consider writing the corresponding directly. The code implements hardware initialization, logging process, and system monitoring process loading and running functions, regardless of complex functions such as process scheduling, memory management, input and output, etc.
2)对原操作系统进行改造。改造原操作系统的初始化流程，在完成硬件初始化后，使其不进入保护模式，不重新初始化中断描述符表(IDT)，而直接使用BIOS的中断描述符表(从而可以直接使用BIOS提供的中断接口)，并在此之后实现日志记录进程和系统的监控进程加载及运行的功能。如此设计可以利用原操作系统硬件初始化流程，减小设计的复杂度；2) Transform the original operating system. Reform the initialization process of the original operating system, after completing the hardware initialization, it does not enter the protection mode, does not re-initialize the interrupt descriptor table (IDT), and directly uses the BIOS interrupt descriptor table (so that the interrupt provided by the BIOS can be directly used Interface), and after that, implement the function of loading and running the logging process and the monitoring process of the system. This design can use the original operating system hardware initialization process to reduce the complexity of the design;
3)直接使用相关的可以运行在实模式中的操作系统，比如DOS操作系统(磁盘操作系统)。如此，可以直接将相关操作系统中实现的相关功能(比如：进程调度、内存管理等)应用在专用CPU核上，实现更为复杂的功能。3) Directly use related operating systems that can run in real mode, such as DOS operating system (disk operating system). In this way, related functions (such as process scheduling, memory management, etc.) implemented in the relevant operating system can be directly applied to the dedicated CPU core to implement more complicated functions.
