Trait for local interrupt controllers (like CLINT)

Local interrupt controllers manage CPU-local interrupts such as timer interrupts and software interrupts.

Required Methods

fn init(&mut self, cpu_id: CpuId) -> InterruptResult<()>

Initialize the local interrupt controller for a specific CPU

fn enable_interrupt( &mut self, cpu_id: CpuId, interrupt_type: LocalInterruptType, ) -> InterruptResult<()>

Enable a specific local interrupt type for a CPU

fn disable_interrupt( &mut self, cpu_id: CpuId, interrupt_type: LocalInterruptType, ) -> InterruptResult<()>

Disable a specific local interrupt type for a CPU

fn is_pending(&self, cpu_id: CpuId, interrupt_type: LocalInterruptType) -> bool

Check if a specific local interrupt type is pending for a CPU

fn clear_interrupt( &mut self, cpu_id: CpuId, interrupt_type: LocalInterruptType, ) -> InterruptResult<()>

Clear a pending local interrupt for a CPU

fn send_software_interrupt(&mut self, target_cpu: CpuId) -> InterruptResult<()>

Send a software interrupt to a specific CPU

fn clear_software_interrupt(&mut self, cpu_id: CpuId) -> InterruptResult<()>

Clear a software interrupt for a specific CPU

fn set_timer(&mut self, cpu_id: CpuId, time: u64) -> InterruptResult<()>

Set timer interrupt for a specific CPU

fn get_time(&self) -> u64

Get current timer value
