Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, compared with a DRAM memory, a memory cell of a DCPMM device is more prone to error, and the DCPMM device is a novel device, and how to process an MCE signal generated by the DCPMM device is a problem to be solved by those skilled in the art.
Therefore, the embodiment of the application discloses an MCE error processing method, which realizes the processing of MCE errors generated by a DCPMM device.
Referring to fig. 1, an MCE error handling method disclosed in an embodiment of the present application includes:
s101: when the DCPMM device has an error, receiving an MCE error sent by a memory controller of the DCPMM device;
in specific implementation, a memory cell of the DCPMM device is more prone to errors, so that ECC verification is required for data reading and writing of the DCPMM device, when uncorrectable errors occur on the data on the memory cell, the DCPMM device labels toxicity of the data of the memory cell and informs a memory controller through a DDRT bus signal, and the memory controller generates an MSMI signal and sends the MSMI signal to a BIOS after knowing that the uncorrectable errors occur on the DCPMM device, and generates an MCE signal and sends the MCE signal to an operating system.
S102: if the operation corresponding to the MCE error does not have the corresponding application program, directly sending the MCE error to a user interaction process;
s103: if the operation corresponding to the MCE error has a corresponding application program, sending the MCE error to a DCPMM recovery process for repair processing;
after the operating system receives the MCE error, the MCE handler is used to determine the corresponding error type, and the MCE handler is responsible for processing the MCE signal.
For MCE errors generated by DCPMM devices, the memory controller error types may include, but are not limited to, memory read and write errors, memory patrol errors, generic undefined requests, etc. When the MCE handler is used for determining that the operation corresponding to the current MCE error does not have the corresponding application program, namely the operation corresponding to the current MCE error is a memory address inspection operation or a general undefined request, the representation cannot acquire further detailed information of the error address corresponding to the current MCE error, and therefore the MCE error is directly sent to the user interaction process. When the MCE handler is used for determining that the operation corresponding to the current MCE error exists in the corresponding application program, namely the operation corresponding to the current MCE error is the memory read-write operation, the MCE error can be sent to the DCPMM recovery process for repair processing.
Specifically, the specific process of sending the MCE error to the DCPMM recovery process for repair processing may be: sending the MCE error to an application program corresponding to the operation; and determining corresponding detailed description information according to the error address corresponding to the MCE error by using the application program, and sending the detailed description information to the DCPMM recovery process so that the DCPMM recovery process can repair the current MCE error by using a data protection mechanism.
It will be appreciated that the above-described application is specifically a DCPMM-friendly application. After the application program receives a signal corresponding to an MCE error sent by an MCE handler, first, detailed description information related to the MCE error can be obtained according to an error address corresponding to the current MCE error, and the detailed description information and the error address are sent to a DCPMM recovery process together, so that the DCPMM recovery process can process the MCE error. If the processing is successful, the MCE processing mechanism may be exited.
S104: if the DCPMM recovery process fails to repair the MCE error, sending the MCE error to the user interaction process;
it should be noted that, if the MCE error is not successfully repaired by the DCPMM recovery process, the MCE error that has failed to be repaired may be sent to the user interaction process for processing.
S105: and determining an error processing mode by utilizing the user interaction process so as to process the MCE error according to the error processing mode.
In the embodiment of the application, detailed description information of the current MCE error can be provided to a user by using a user interaction process, and the user selects a processing mode for the current MCE error. Specifically, detailed description information of the current MCE error can be displayed through a preset interactive interface, and further, all selectable processing modes can be displayed, and a user can select the error processing mode through clicking or touching and the like so as to process the MCE error according to the processing mode.
According to the above scheme, the MCE error processing method provided by the present application includes: when the DCPMM device has an error, receiving an MCE error sent by a memory controller of the DCPMM device; if the operation corresponding to the MCE error does not have the corresponding application program, directly sending the MCE error to a user interaction process; if the operation corresponding to the MCE error has a corresponding application program, sending the MCE error to a DCPMM recovery process for repair processing; if the DCPMM recovery process fails to repair the MCE error, sending the MCE error to the user interaction process; and determining an error processing mode by utilizing the user interaction process so as to process the MCE error according to the error processing mode. Therefore, according to the application, after the DCPMM device generates an error, the MCE error is sent through the memory controller, the MCE error can be sent to the DCPMM recovery process to be repaired according to whether the operation corresponding to the MCE error exists in the corresponding application program or not, or the MCE error is sent to the user interaction process, the user interaction process determines the error processing mode and processes the MCE error, and the processing aiming at the MCE error generated by the DCPMM device is realized.

s205: if the target data corresponding to the error address is stored in the cache storage, performing a flushing operation on the cache storage so as to flush the target data to the error address;
it should be noted that, in the embodiment of the present application, when an application corresponding to an MCE error exists in an operation corresponding to the MCE error, for example, when the operation is a memory read-write operation, after the MCE error is sent to the DCPMM recovery process, an error address corresponding to the current MCE error may be determined by using the DCPMM recovery process, and the error address may be further determined how to perform data rewriting on the error address.

it can be understood that, if the storage area where the error address is located has mirror storage, the embodiment of the present application may read the target data corresponding to the current error address from the mirror storage, and rewrite the target data into the current error address, so that the writing is successful with a higher probability.
S207: if the error address belongs to the address in the software disk array, performing data recovery by using a RAID data recovery mechanism;
if the address in the error address software disk array, such as RAID5, RAID6, etc., the data recovery can be directly performed by using a general RAID data recovery mechanism, so as to complete the data recovery.

s304: if the DCPMM recovery process fails to repair the MCE error, sending the MCE error to the user interaction process;
s305: determining a use mode of an error address corresponding to the MCE error by using the user interaction process;
in this embodiment of the application, if there is no corresponding application program for an operation corresponding to an MCE error, or the MCE error is unsuccessfully repaired by using the DCPMM recovery process, the operation may be sent to the user interaction process. Specifically, information such as an error address corresponding to the MCE error, a usage mode to which the error address belongs, an address mapping type, and a related file type may be sent.
It should be noted that the DCPMM generally has two usage modes, including a memory mode and a persistent storage mode. In the memory mode, the DCPMM device is volatile, that is, all contents are cleared after the system is restarted, that is, an uncorrectable error in the memory mode automatically disappears after the system is restarted. In the persistent storage mode, the DCPMM device is in persistent storage, and data in the DCPMM device does not change after the system is shut down or restarted.
S306: and providing a corresponding error processing mode by using the user interaction process according to the use mode, and receiving a selection instruction aiming at the error processing mode through a preset interface so as to process the MCE error according to the error processing mode selected by the selection instruction.
As a feasible implementation manner, if the use mode to which the error address corresponding to the MCE error belongs is a memory mode, that is, the error will automatically disappear after the system is restarted or shut down, a first type of processing manner may be provided by using a user interaction process; the first processing mode may include, but is not limited to, ignoring the current MCE error to continue the system operation; the system is restarted. That is, if the current error has no influence on the operation or use of the subsequent system, the current MCE error can be ignored, the MCE processing mechanism is exited, and the operation of the system is continued; if the current error has influence on the operation or use of the subsequent system, the MCE processing mechanism can be quitted, and the system is restarted after important information of the system is stored.
If the use mode persistent storage mode to which the error address corresponding to the MCE error belongs is the use mode persistent storage mode, namely the error still exists after the system is restarted or shut down, a second type of processing mode can be provided for the user by utilizing the user interaction process; the second processing manner may include, but is not limited to: deleting the current data of the error address; or to overwrite the current data of the wrong address. When the current data of the error address is overwritten, a specific value may be used for overwriting, for example, the current data of the error address is overwritten by a value 0; other files may also be used for overwriting, such as using the last backup of the file corresponding to the error address to overwrite the current data at the error address. The data coverage manner may be default by the system, or may be specified by the user according to the requirement, and is not specifically limited herein.
