Problems solved by technology
[0003] However, the introduction of the lock mechanism also leads to the risk of deadlock in the operating system. Due to the uncertainty of running programs on multi-core processors, deadlocks often occur, and when deadlocks occur, it often takes a long time for operation and maintenance personnel to solve the problem. The location where the deadlock occurs is detected, which greatly affects the efficiency of problem repair

The invention discloses a deadlock detection method. The method comprises the following steps: after locking operation is conducted, obtaining address information of a lock; performing hash operationon the address information to obtain a corresponding hash value; judging whether a hash value exists in a preset record table or not; and if so, determining a deadlock occurrence position according tothe address information corresponding to the hash value. According to the invention, the generated deadlock is detected by using the hash algorithm; when the hash value exists in the preset record table, it is indicated that the lock is already locked before, and deadlock is caused by locking again; the deadlock occurrence position is determined according to the address information correspondingto the hash value at the moment, the problem repairing efficiency is improved, and the product quality and the stability of an operating system are improved. The invention further provides a deadlockdetection system and device and a readable storage medium, which have the above beneficial effects.
Description
technical field [0001] The present application relates to the field of deadlock detection, in particular to a deadlock detection method, system, device and readable storage medium. Background technique [0002] In modern operating systems and software development, multi-core concurrent programs have been widely used in practical applications due to their high resource utilization and fast computing speed. However, due to the uncertainty and complexity of multi-core concurrent behavior, its development and maintenance are more difficult than single-core. Therefore, in multi-core programming, in order to ensure the consistency of data operations, the operating system introduces a lock mechanism to ensure the safety of critical section codes. [0003] However, the introduction of the lock mechanism also leads to the risk of deadlock in the operating system. Due to the uncertainty of running programs on multi-core processors, deadlocks often occur, and when deadlocks occur, it ...
