The conditions for deadlock generation are: the processes P1, P2 and P3 respectively apply for three resources R1, R2 and R3 simultaneously, but the three processes are already allocated to the resources R3, R1 and R2 respectively, so that the situation that the process P1 needs to wait for the P2 process when applying for R1, the process P2 needs to wait for R3 process when applying for R2, and the process P3 needs to wait for the P1 process when applying for R3, so that the three processes wait for each other, and a loop waiting state occurs, and deadlock is generated.

Example one

An embodiment of the present invention provides a resource allocation method, as shown in fig. 3, the method may include:

s101, when a first use request is received through a first process, resources to be used carried by the first use request are obtained, and the resources to be used are distributed to the process at the same time.

The resource allocation method provided by the embodiment of the invention is suitable for a scene that a process applies for using mutually exclusive resources.

In the embodiment of the invention, when a first process in the terminal applies for the resource to be used, the terminal receives a first use request through the first process, and at the moment, the terminal acquires the resource to be used carried by the first use request.

In the embodiment of the invention, the terminal registers the first process number corresponding to the first process and the resource to be used in the resource management process.

In the embodiment of the invention, the resource management process is a resident process for managing the mutually exclusive resources, and the storage format in the resource management process is as follows: application bits, usage bits, and usage flag values.

In the embodiment of the invention, the resource management adds the first process number to the application bit of the resource to be used, and sets the use flag value as the second preset value.

In the embodiment of the invention, the use flag value comprises a first preset value and a second preset value, wherein the first preset value represents that the resource to be used is not allocated, and the second preset value represents that the resource to be used is allocated.

Illustratively, the process P1 applies for using the resource R1, the terminal registers the resource R1 with the resource manager W, the resource management process W adds P1 to the application bit of R1, and the value of the use flag of R1 is set to 0.

In the embodiment of the present invention, the terminal includes a computer, a terminal and other terminals that need to perform resource allocation, and the selection is specifically performed according to an actual situation, which is not specifically limited in the embodiment of the present invention.

In the embodiment of the invention, the resource to be used can only be allocated to one process at the same time and cannot be shared by a plurality of processes, namely, the resource to be used is a mutually exclusive resource.

S102, when the resource management process is used for judging that the resources to be used are distributed, a second process and distribution duration corresponding to the resources to be used are obtained from the resource management process.

After the terminal acquires the resource to be used, the terminal judges whether the resource to be used is allocated by using the resource management process, and after the terminal judges that the resource to be used is allocated, the terminal acquires a second process and allocation duration corresponding to the resource to be used from the resource management process.

In the embodiment of the invention, the terminal determines the use mark value of the resource to be used from the resource management process, and when the use mark value is a first preset value, the terminal judges that the resource to be used is distributed; and when the use flag value is the second preset value, the terminal judges that the resource to be used is not allocated.

Illustratively, when the value of the use flag is 1, the resource to be used is characterized to be allocated; when the value of the use flag is 0, the resource to be used is not allocated.

In the embodiment of the invention, when the terminal judges that the resources to be used are distributed, the terminal acquires the second process with the use permission of the resources to be used and the distribution duration distributed to the use permission of the second process from the resource management process.

In the embodiment of the invention, the terminal acquires the second process number corresponding to the second process from the use position of the resource to be used, determines the set time length for setting the use flag value as the second preset value by using the resource management process, and determines the set time length as the allocation time length for allocating the resource to be used by the second process.

Further, when the terminal determines that the resource to be used is not allocated, the terminal allocates the usage right of the resource to be used to the first process.

S103, when the allocation duration reaches the preset allocation duration, releasing the use permission of the resources to be used in the second process so as to carry out the process of applying for the resources to be used in the next round.

When the terminal determines the second process and the allocation duration, the terminal compares the allocation duration with the preset allocation duration, when the allocation duration reaches the preset allocation duration, the terminal judges that the system is deadlocked, at the moment, the terminal releases the use permission of the second process to the resources to be used, and the process of applying for the resources to be used in the next round is carried out.

In the embodiment of the invention, the terminal stores the preset allocation duration, when the terminal determines the allocation duration, the terminal compares the allocation duration with the preset allocation duration, and when the allocation duration reaches the preset allocation duration, the terminal releases the use permission of the resource to be used by the second process, at this time, the terminal does not allow any process to hold the resource to be used, and applies for and calculates the resource to be used again.

In the embodiment of the invention, the resource management process sets the use bit of the resource to be used to be null and changes the use flag value to the second preset value.

Further, when the terminal judges that the allocation duration does not reach the preset allocation duration, the terminal indicates the first process to wait for the resource to be used, and detects whether the allocation duration reaches the preset allocation duration in real time.

Illustratively, as shown in fig. 4, the process R1 applies for using the P1 resource, at this time, the usage flag value of P1 is 1, the current usage process is shown as R2 in the usage bit of P1, and when the terminal determines that the allocation duration of the usage flag value of 1 is longer than the preset allocation duration, the terminal sets the usage bit to null and sets the usage flag value to 0.

It can be understood that the terminal establishes a resource management process, the process manages resources to be used, when the first process applies for using the resources to be used which are already allocated to the second process, the terminal judges whether the allocation duration of the resources to be used reaches the preset allocation duration by using the resource management process, when the allocation duration reaches the preset allocation duration, the terminal releases the use permission of the resources to be used by the second process, and directly performs the next application process of applying for the resources to be used, the terminal does not need to establish a plurality of data structures to perform the processes of determining the application amount, postponing allocation and the like, and the overhead of the terminal can be reduced.

In the embodiment of the invention, the terminal sets the use flag value of the resource to be used as the first preset value, and at the moment, the terminal starts to record the duration set as the first preset value.

And S207, when the use flag value is the first preset value, the terminal judges that the resource to be used is allocated.

After the terminal acquires the usage flag value, the terminal determines that the specific value of the usage flag value is taken. And when the use flag value is the first preset value, the terminal judges that the resource to be used is allocated.
