Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. Embodiments and features of embodiments in this application may be combined with each other arbitrarily without conflict. The steps illustrated in the flowchart of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.

The technical scheme of the application is further elaborated below with reference to the drawings in the specification and the specific embodiments.

Fig. 1 is a schematic diagram of a flow implementation of a data processing method in the present application, where the method may be applied to various electronic devices, such as a mobile phone, a computer, a watch, a television, a data processing device, a medical device, a tablet device, and so on. And is particularly applicable to system firmware of the electronic device. As shown in fig. 1, the method includes:

step 101, in response to detecting that a persistent error event occurs in a mirror memory in the running process of a system, acquiring a physical address corresponding to the persistent error event through an interrupt program of system firmware;

in the application, the electronic device can detect whether an error event exists in a main memory channel of the mirror memory in the running process of the system, and if the error event exists in the main memory channel of the mirror memory, the electronic device acquires target data corresponding to the error event from a slave memory channel of the mirror memory; the slave memory channel and the master memory channel have the same stored data; then, the occurrence times of the error event are determined after the target data are written into the main memory channel; and comparing the occurrence times with a data threshold value to obtain a comparison result. If the comparison result indicates that the occurrence times are larger than the time threshold, determining that the error event is a persistent error event, and acquiring a physical address corresponding to the persistent error event through an interrupt program of system firmware.

In one implementation, the electronic device may obtain, from a host processor of the system, a physical address corresponding to the persistent error event through an interrupt program of system firmware. The interrupt routine of the system firmware may refer to a system management interrupt (SMI, system Management Interrupt) of the unified extensible firmware interface (UEFI, unified Extensible Firmware Interface).

At this time, the system may be different according to the type of the device, such as an operating system of a computer, an operating system of a mobile phone, and the like.

Step 102, storing the physical address in a hardware error source table of the system firmware;

in this application, the electronic device may create a specific generic hardware error source structure in the hardware error source table (HEST, hardware Error Source Table) by the system firmware before booting the system; the specific general hardware error source structure is used for storing a physical address corresponding to the persistent error event. After the electronic device obtains the physical address corresponding to the persistent error event through the interrupt program of the system firmware, the physical address may be stored in the generic hardware error source structure.

Here, this particular generic hardware error source structure may be referred to as GHESS.

And step 103, sending an interrupt signal to the system so that the system can disconnect the mapping relation between the physical address and the virtual address in the hardware error source table according to the interrupt signal and remap the virtual address.

Here, taking an example that the system of the electronic device may operate in an OS environment, the electronic device may send an interrupt signal to the system using a system control interrupt (SCI, system Control Interrupt) method to trigger an OS interrupt. At this time, the system may unbind the mapping relationship between the physical address and the virtual address in the hardware error source table, and remap the virtual object.

According to the data processing method, when the persistent error event exists in the mirror memory, only the physical address and the virtual object of the persistent error event are unbinding, and the mirror function of the mirror memory still works, so that the correction of other short uncorrectable errors or persistent uncorrectable errors can be facilitated, and as no operating system or application program accesses the persistent memory, the memory controller is not required to attempt to correct the persistent error, and therefore the performance of the system is not affected.

Fig. 2 is a second flow chart of a data processing method in the present application, where the method may be applied to the electronic device, and in particular, may be applied to a system in the electronic device. As shown in fig. 2, the method comprises the steps of:

step 201, receiving an interrupt signal sent by an interrupt program of system firmware in a system running process;

step 202, acquiring a physical address of a mirror image memory from a hardware error source table of the system firmware based on the interrupt signal, wherein the physical address represents a current occurrence of a persistent error event;

and 203, disconnecting the mapping relation between the physical address and the virtual address, and remapping the virtual address.

Here, the Hardware Error Source Table (HEST) includes at least a Generic Hardware Error Source Structure (GHESS), and when the electronic device obtains the physical address of the image memory from the hardware error source table of the system firmware based on the interrupt signal, the electronic device may obtain the physical address of the image memory from the generic hardware error source structure based on the interrupt signal, where the generic hardware error source structure is created by the system firmware before booting the system.

Here, the electronic device breaking the mapping relationship between the physical address and the virtual address refers to unbinding the mapping relationship between the physical address and the virtual address.

It should be noted that: the data processing method provided in the foregoing embodiment corresponds to the system side of the embodiment of the data processing method provided in fig. 1, and belongs to the same concept as the embodiment provided in fig. 1, and the specific implementation process may refer to the method embodiment of fig. 1, which is not repeated herein.

Fig. 3 is a flow chart III of a data processing method in the present application, as shown in fig. 3, the method includes:

step 301, powering up a system;

step 302, initializing an SMI module by a UEFI module;

here, some processes before the initialization of the memory by the UEFI module is completed, for example, may be further included between the step 302 and the step 301, and thus, a related description is omitted herein because these processes are conventional processes initiated by a computer.

Step 303, the uefi module initializes APCI GHESS in the list of list;

in step 304, the uefi module boots the operating system.

Here, some processes after the UEFI module successfully initializes the memory may be included between the step 304 and the step 303, and thus, a related description is omitted herein because these processes are conventional processes initiated by the computer.

Here, after the operating system is successfully booted, the method further includes:

step 305, detecting that a persistent error event occurs in the mirror memory in the running process of the system, and acquiring a physical address of the persistent error event through an SMI module;

step 306, storing, by the SMI module, the physical address of the persistent error event in a GHESS table;

step 307, triggering an operating system interrupt by the SMI module by using the SCI mode;

here, the specific SMI module sends an interrupt signal to the background interrupt program of the OS to inform the OS that there is a memory error currently. And then jumping from the OS background program to the OS foreground program.

In step 308, the operating system and the application program under the operating system disconnect the mapping relationship between the physical address and the virtual address in the GHESS table according to the interrupt signal.

After receiving the interrupt signal, the OS jumps to the OS background program from the OS foreground program, processes the interrupt signal, and jumps to the OS foreground program from the OS background program to continue running after the interrupt signal is processed.

When there is a persistent error event in the mirror memory, the operating system only disconnects the mapping relation between the physical address and the virtual address of the persistent error event, so that the image function of the mirror memory is not affected, that is, the mirror function of the mirror memory can be continuously used after the persistent error event is interrupted, and the user side only performs fault transfer on the persistent error event in the mirror memory.

The embodiment of the application also provides electronic equipment, which comprises: a processor and a memory for storing a computer program capable of running on the processor,

wherein the processor is configured to execute any of the method steps of the above-described processing method when the computer program is run.
