Classification: CPC G | IPC G

Claim 1:
2. The method of claim 1, further comprising:
storing, by an interrupt controller of the computer system, 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, and wherein the first subsystem and the second subsystem share the interrupt controller;
receiving, by the interrupt controller, an interrupt request from an interrupt initiator, wherein the interrupt request comprises an interrupt initiator safety level of the interrupt initiator;
determining, by the interrupt controller, whether the interrupt initiator safety level matches a interrupt receiver safety level of an interrupt receiver corresponding to the interrupt initiator and based on the interrupt request; and
allowing, by the interrupt controller, the interrupt receiver to accept the interrupt request when the interrupt initiator safety level matches the interrupt receiver safety level.
