Embodiment Construction

[0015] The application will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 Shown is an embodiment of a log storage method provided by the present application, the method comprising:

[0017] S101. Acquire the first subscript of the ring storage queue.

[0018] Since the storage space does not have a ring structure, the ring storage queue in this application is actually implemented through the linear space of the array, and each array element corresponds to each storage block. If the system log is stored in the ring storage queue, when the storage space reaches the tail storage block of the ring storage queue, it needs to switch back to the head storage block of the ring storage queue. The modulo operation of the array realizes jumping from the tail storage block to the head storage block. The above-mentioned circular storage queue is actually a flash ring space that connects multiple storage blocks to form a storage queu...

Abstract

The embodiment of the present application discloses a log storage method, system and storage device, including: obtaining the first subscript of the ring storage queue; determining the first storage offset address corresponding to the first subscript; if the current The storage capacity is equal to the storage upper limit of the log buffer area, the system log in the log buffer area is stored in the storage block indicated by the first storage offset address in the ring storage queue, and the log buffer area is cleared, based on the first subscript Determine the second subscript and its corresponding second storage offset address. After the system log in the log buffer area is saved to the first storage offset address, the second offset address corresponding to the storage block used to save the system log when the log buffer area reaches the storage upper limit at the next moment is obtained, which ensures that the flash The writing is balanced, and the same storage block in the flash will not be erased and written multiple times, which improves the life of the storage block.

Description

technical field [0001] The present application relates to the technical field of embedded systems, in particular to a log storage method, system and storage device. Background technique [0002] Embedded system logs are information that records hardware, software, and system problems in embedded systems, and can also monitor events that occur in embedded systems. Users can check the cause of embedded system errors through the system log, or look for traces left by the attacker when the system is attacked. Especially for the tracking and positioning of some embedded devices whose bugs are not easy to reproduce, it provides a strong basis. [0003] Existing embedded system log preservation generally relies on existing file system partitions, such as the jsff2 partition in the embedded system. Since the log saving of the embedded system is only a part of the operation of the embedded system, in order to ensure the normal operation of the embedded system, it is necessary to in...
