Implementations

source

impl Apic

source

pub fn new(acpi_rsdp: usize, phys_to_virt: fn(paddr: usize) -> usize) -> Self

Construct a new Apic.

source

pub fn register_local_apic_handler(
    &self,
    vector: usize,
    handler: IrqHandler
) -> DeviceResult

Trait Implementations

source

impl IrqScheme for Apic

source

fn is_valid_irq(&self, gsi: usize) -> bool

Is a valid IRQ number.

source

fn mask(&self, gsi: usize) -> DeviceResult

Disable IRQ.

source

fn unmask(&self, gsi: usize) -> DeviceResult

Enable IRQ.

source

fn configure(
    &self,
    gsi: usize,
    tm: IrqTriggerMode,
    pol: IrqPolarity
) -> DeviceResult

Configure the specified interrupt vector. If it is invoked, it must be invoked prior to interrupt registration. Read more

source

fn register_handler(&self, gsi: usize, handler: IrqHandler) -> DeviceResult

Add an interrupt handler to an IRQ.

source

fn unregister(&self, gsi: usize) -> DeviceResult

Remove the interrupt handler to an IRQ.

source

fn msi_alloc_block(&self, requested_irqs: usize) -> DeviceResult<Range<usize>>

Method used for platform allocation of blocks of MSI and MSI-X compatible IRQ targets. Read more

source

fn msi_free_block(&self, block: Range<usize>) -> DeviceResult

Method used to free a block of MSI IRQs previously allocated by msi_alloc_block(). This does not unregister IRQ handlers. Read more

source

fn msi_register_handler(
 &self,
 block: Range<usize>,
 msi_id: usize,
 handler: IrqHandler
) -> DeviceResult

Register a handler function for a given msi_id within an msi_block_t. Passing a NULL handler will effectively unregister a handler for a given msi_id within the block. Read more

source

fn apic_timer_enable(&self)

[for x86_64] enable apic timer

source

fn register_device(&self, irq_num: usize, dev: Arc<dyn Scheme>) -> DeviceResult

Register the device to delivery an IRQ.

source

fn init_hart(&self)

Init irq for current cpu. Some IRQ hardware requires per-CPU initialization. Read more

source

impl Scheme for Apic

source

fn name(&self) -> &str

Returns name of the driver.

source

fn handle_irq(&self, vector: usize)

Handles an interrupt.
