Function Documentation

max_irq_disable()

int max_irq_disable	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id )

Disable a specific interrupt.

Parameters

desc	- Interrupt controller descriptor.
irq_id	- The interrupt vector entry id of the peripheral.

Returns

0 in case of success, errno error codes otherwise.

max_irq_enable()

int max_irq_enable	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id )

Enable a specific interrupt.

Parameters

desc	- Interrupt controller descriptor.
irq_id	- The interrupt vector entry id of the peripheral.

Returns

0 in case of success, errno error codes otherwise.

max_irq_global_disable()

int max_irq_global_disable

(

struct no_os_irq_ctrl_desc *

desc

)

Disable all interrupts.

Parameters

desc	- Interrupt controller descriptor.

Returns

0

max_irq_global_enable()

int max_irq_global_enable

(

struct no_os_irq_ctrl_desc *

desc

)

Enable all interrupts.

Parameters

desc	- Interrupt controller descriptor.

Returns

0

max_irq_set_priority()

int max_irq_set_priority	(	struct no_os_irq_ctrl_desc *	desc,
		uint32_t	irq_id,
		uint32_t	priority_level )

Set the priority of an interrupt (not supported on CPU1)

Set a priority level for an interrupt.

Parameters

desc	- Interrupt controller descriptor.
irq_id	- The interrupt vector entry id of the peripheral.
priority_level	- The interrupt priority level.

Returns

-EINVAL for an invalid irq_id, -ENOTSUP otherwise.
