Interrupt Processing Method and Apparatus, and Electronic Device

An electronic device, comprising:

• one or more memories configured to store instructions;
• and
• one or more processors coupled to the one or more memories, wherein when executed by the one or more processors, the instructions cause the electronic device to
• determine, in response to a first interrupt request, a target central processing unit (CPU) to respond to the first interrupt request;
• determine a first target interrupt running entity in the target CPU;
• switch, in response to the first interrupt request, a target thread from a user mode to a kernel mode;
• replace a running entity of the target thread with the first target interrupt running entity;
• switch back the target thread comprising the first target interrupt running entity from the kernel mode to the user mode;
• and
• run the first target interrupt running entity using the target CPU.

A chip comprising:

• a communication interface configured to receive a signal;
• and
• a processor coupled to the communication interface and configured to processes the signal to:
• determine, in response to a first interrupt request, a target central processing unit (CPU) to respond to the first interrupt request;
• determine a first target interrupt running entity in the target CPU;
• switch, in response to the first interrupt request, a target thread from a user mode to a kernel mode;
• replace a running entity of the target thread with the first target interrupt running entity;
• switch back the target thread from the kernel mode to the user mode;
• and
• run the first target interrupt running entity using the target CPU.
