Function Documentation

dt_rv_plic_alert_from_alert_id()

dt_rv_plic_alert_t dt_rv_plic_alert_from_alert_id	(	dt_rv_plic_t	dt,
		dt_alert_id_t	alert )

Convert a global alert ID to a local rv_plic alert type.

Parameters

dt	Instance of rv_plic.
alert	A global alert ID that belongs to this instance.

Returns

The rv_plic alert, or kDtRvPlicAlertCount.

Note: This function assumes that the global alert ID belongs to the instance of rv_plic passed in parameter. In other words, it must be the case that dt_rv_plic_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtRvPlicAlertCount.

Definition at line 84 of file dt_rv_plic.c.

dt_rv_plic_alert_to_alert_id()

dt_alert_id_t dt_rv_plic_alert_to_alert_id	(	dt_rv_plic_t	dt,
		dt_rv_plic_alert_t	alert )

Get the alert ID of a rv_plic alert for a given instance.

Note: This function only makes sense if the instance is connected to the Alert Handler. For any instances where the instance is not connected, the return value is unspecified.

Parameters

dt	Instance of rv_plic.
alert	A rv_plic alert.

Returns

The Alert Handler alert ID of the alert of this instance.

Definition at line 78 of file dt_rv_plic.c.

dt_rv_plic_clock()

dt_clock_t dt_rv_plic_clock	(	dt_rv_plic_t	dt,
		dt_rv_plic_clock_t	clk )

Get the clock signal connected to a clock port of an instance.

Parameters

dt	Instance of rv_plic.
clk	Clock port.

Returns

Clock signal.

Definition at line 96 of file dt_rv_plic.c.

dt_rv_plic_from_instance_id()

dt_rv_plic_t dt_rv_plic_from_instance_id

(

dt_instance_id_t

inst_id

)

Get the rv_plic instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id

Instance ID.

Returns

A rv_plic instance.

Note: This function only makes sense if the instance ID has device type rv_plic, otherwise the returned value is unspecified.

Definition at line 58 of file dt_rv_plic.c.

dt_rv_plic_instance_id()

dt_instance_id_t dt_rv_plic_instance_id

(

dt_rv_plic_t

dt

)

Get the instance ID of an instance.

Parameters

dt	Instance of rv_plic.

Returns

The instance ID of that instance.

Definition at line 65 of file dt_rv_plic.c.

dt_rv_plic_reg_block()

uint32_t dt_rv_plic_reg_block	(	dt_rv_plic_t	dt,
		dt_rv_plic_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of rv_plic.
reg_block	The register block requested.

Returns

The register base address of the requested block.

Definition at line 70 of file dt_rv_plic.c.

dt_rv_plic_reset()

dt_reset_t dt_rv_plic_reset	(	dt_rv_plic_t	dt,
		dt_rv_plic_reset_t	rst )

Get the reset signal connected to a reset port of an instance.

Parameters

dt	Instance of rv_plic.
rst	Reset port.

Returns

Reset signal.
