Method for accessing exclusive device and related apparatus

A network device, comprising:

• an exclusive device,
• a memory storing instructions;
• and
• at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
• obtain, by a first controller, a first request message from a first application, wherein the first request message is used to request to access the exclusive device, both the first controller and the first application are run in a first operating system, and the first operating system is run on a processor other than the exclusive device;
• and
• in response to a second operating system being started, send, by the first controller based on the first request message, a second request message to a second application run in the second operating system, wherein the second request message is used to request the second application to assist in accessing the exclusive device, wherein
• the second operating system is run on the processor other than the exclusive device, the processor that runs the first operating system and the second operating system is connected to the exclusive device through a bus, a second controller is run in the second operating system, and the second controller is configured to control mutually exclusive access of the application in the second operating system to the exclusive device.

A non-transitory computer readable storage medium storing a program of instructions executable by a computer to perform:

• obtain, by a first controller, a first request message from a first application, wherein the first request message is used to request to access an exclusive device of the computer, both the first controller and the first application are run in a first operating system, and the first operating system is run on a processor of the computer other than the exclusive device;
• and
• in response to a second operating system being started, send, by the first controller based on the first request message, a second request message to a second application run in the second operating system, wherein the second request message is used to request the second application to assist in accessing the exclusive device, wherein
• the second operating system is run on the processor of the computer other than the exclusive device, the processor that runs the first operating system and the second operating system is connected to the exclusive device through a bus, a second controller is run in the second operating system, and the second controller is configured to control mutually exclusive access of the application in the second operating system to the exclusive device.
