Problems solved by technology
[0009] In order to solve the problem in the background technology that when a large number of correctable faults occur in a hardware module within a short period of time, the operating system will be in a continuous fault processing state, occupying a large amount of processing resources of the operating system, and even causing the operating system to fail to run normally. The embodiment provides a fault device and method

Embodiment Construction
[0066] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0067] For the convenience of understanding, some nouns appearing in the embodiments of the present invention are first explained:
[0068] Disabled state: refers to the state in which the hardware module cannot generate a correctable fault interrupt based on the correctable fault, that is, the state in which the operating system cannot receive the correctable fault interrupt generated by the hardware module. The mechanism by which correctable fault interrupts are generated by each hardware module is generally independent of the other.
[0069] Enabled state: refers to the state in which the hardware module can generate correctable fault interrupts based on correctable faults, that is, the state in which the operating system can receiv...

The invention discloses a device and a method for treating faults, and belongs to the technical field of computers. The method comprises the following steps of calculating the frequency of corrective fault interruption of a hardware module of a server within the preset time period; detecting whether the frequency is greater than the disenabling threshold value or not; when the detecting result shows that the frequency is greater than the disenabling threshold value, switching the enabling state of the corrective fault interruption of the hardware module into the disenabling state. The method solves the problem that the operation system cannot normally run as the operation system is in the continuous fault treatment state and a large amount of treatment resources of the operation system is occupied when a large amount of corrective faults of the hardware module occurs in short time. The method can realize the effects that the corrective fault interruption is reduced, the operation system can normally run, and the running efficiency of the operation system is improved when a large amount of corrective faults of the hardware module occurs in short time.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a fault processing device and method. Background technique [0002] A correctable fault is a common hardware fault that occurs while the server is running. [0003] When a correctable fault occurs, the hardware module generates a correctable fault interrupt (English: Corrected Machine-Check Error Interrupt; CMCI for short) according to the correctable fault, and notifies the operating system to enter the interrupt handler to process the correctable fault interrupt, The operating system determines the hardware module according to the correctable fault interrupt and performs corresponding fault processing. Taking the correctable fault occurring in the memory as an example, the steps for the interrupt handler in the operating system to handle the correctable fault interrupt are as follows: [0004] 1. The interrupt handler collects the fault data corresponding to the correctable...
