Classification: CPC G | IPC G

Claim 10:
11. The computer system of claim 8, further comprising an interrupt controller coupled to the first subsystem and the second subsystem, wherein the interrupt controller is shared by the first subsystem and the second subsystem, and wherein the interrupt controller is configured to:
store interrupt routing configuration information configured by the first CPU core, wherein the interrupt routing configuration information indicates a third CPU core of the computer system configured to respond to an interrupt;
receive an interrupt request from an interrupt initiator, wherein the interrupt request comprises an interrupt initiator safety level of the interrupt initiator;
determine whether the interrupt initiator safety level matches an interrupt receiver safety level of an interrupt receiver corresponding to the interrupt initiator and based on the interrupt request; and
allow the interrupt receiver to accept the interrupt request when the interrupt initiator safety level matches the interrupt receiver safety level.
