Detailed Description

TMS570 interrupt support functions definitions.

Function Documentation

bsp_interrupt_dispatch()

void bsp_interrupt_dispatch

(

void

)

Interrupt dispatch.

Called by OS to determine which interrupt occured. Function passes control to interrupt handler.

Returns

Void

tms570_irq_get_priority()

unsigned tms570_irq_get_priority

(

rtems_vector_number

vector

)

Gets priority of the interrupt vector.

This function is here because of compability. It returns priority of the isr vector last set by tms570_irq_set_priority function.

Warning

It does not return any real priority of the HW layer.

Parameters

[in]

vector

vector of isr

Return values

0	vector is invalid.
priority	priority of the interrupt

tms570_irq_set_priority()

void tms570_irq_set_priority	(	rtems_vector_number	vector,
		unsigned	priority
	)

Set priority of the interrupt vector.

This function is here because of compability. It should set priority of the interrupt vector.

Warning

It does not set any priority at HW layer. It is nearly imposible to

set priority of the interrupt on TMS570 in a nice way.

Parameters

[in]	vector	vector of isr
[in]	priority	new priority assigned to the vector

Returns

Void
