Function Documentation

init_storage()

void ecl::irq::init_storage

(

)

Initializes storage for callbacks and setups default handler for every IRQ.

Here is the call graph for this function:

subscribe()

void ecl::irq::subscribe	(	irq_num	irqn,
		const irq::handler_type &	handler
	)

Subscribes to the given IRQ.

Parameters

[in]	irqn	Valid IRQ number.
[in]	handler	New IRQ handler for given IRQ.

Here is the call graph for this function:

unsubscribe()

void ecl::irq::unsubscribe

(

irq_num

irqn

)

Unsubscribes from the given IRQ.

Default handler will be used for given IRQ if this call succeed.

Parameters

[in]

irqn

Valid IRQ number.

Here is the call graph for this function:

mask()

static void ecl::irq::mask ( irq_num  irqn )

inlinestatic

Masks or disables the given IRQ.

Parameters

[in]

irqn

Valid IRQ number.

unmask()

static void ecl::irq::unmask ( irq_num  irqn )

inlinestatic

Unmasks or enables the given IRQ.

Parameters

[in]

irqn

Valid IRQ number.

get_current_irqn()

static irq_num ecl::irq::get_current_irqn ( )

inlinestatic

Gets current IRQ number.

Warning

Results are unspecified if called not within IRQ context.

Returns

Current IRQ number

in_isr()

static bool ecl::irq::in_isr ( )

inlinestatic

Checks if a processor is in handler mode of execution at this time.

Return values

true	Processor is in handler mode. I.e. servicing IRQ or exception.
false	Processor is in thread mode.

disable()

static void ecl::irq::disable ( )

inlinestatic

Disables interrupts globally.

enable()

static void ecl::irq::enable ( )

inlinestatic

Enables interrupts globally.

clear()

static void ecl::irq::clear ( irq_num  irqn )

inlinestatic

Clears pending interrupt of the given IRQ.

Parameters

[in]

irqn

Valid IRQ number.
