Description of instances.

Definition at line 19 of file dt_rv_timer.c.

Data Fields
uint32_t	base_addr[kDtRvTimerRegBlockCount]	Base address of each register block.
dt_clock_t	clock[kDtRvTimerClockCount]	Clock signal connected to each clock port.
top_darjeeling_alert_id_t	first_alert	Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler.

top_darjeeling_plic_irq_id_t	first_irq	PLIC ID of the first IRQ of this instance. This can be `kDtPlicIrqIdNone` if the block is not connected to the PLIC.
top_earlgrey_plic_irq_id_t	first_irq	PLIC ID of the first IRQ of this instance. This can be `kDtPlicIrqIdNone` if the block is not connected to the PLIC.
top_englishbreakfast_plic_irq_id_t	first_irq	PLIC ID of the first IRQ of this instance. This can be `kDtPlicIrqIdNone` if the block is not connected to the PLIC.

Macro Definition Documentation

◆ TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({ if ((dt) < (dt_rv_timer_t)0 || (dt) >= kDtRvTimerCount) return (default); &rv_timer_desc[dt]; })

Return a pointer to the dt_rv_timer_desc_t structure of the requested dt if it's a valid index.

Otherwise, this macro will return (i.e. exit the function) with the provided default value.

Function Documentation

◆ dt_rv_timer_alert_from_alert_id()

dt_rv_timer_alert_t dt_rv_timer_alert_from_alert_id	(	dt_rv_timer_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns: The rv_timer alert, or kDtRvTimerAlertCount.

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

Definition at line 115 of file dt_rv_timer.c.

◆ dt_rv_timer_alert_to_alert_id()

dt_alert_id_t dt_rv_timer_alert_to_alert_id	(	dt_rv_timer_t	dt,
		dt_rv_timer_alert_t	alert )

Get the alert ID of a rv_timer 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_timer.
alert	A rv_timer alert.

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

Definition at line 109 of file dt_rv_timer.c.

◆ dt_rv_timer_clock()

dt_clock_t dt_rv_timer_clock	(	dt_rv_timer_t	dt,
		dt_rv_timer_clock_t	clk )

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

Parameters

dt	Instance of rv_timer.
clk	Clock port.

Returns: Clock signal.

Definition at line 127 of file dt_rv_timer.c.

◆ dt_rv_timer_from_instance_id()

dt_rv_timer_t dt_rv_timer_from_instance_id ( dt_instance_id_t inst_id )

Get the rv_timer instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id Instance ID.

Returns: A rv_timer instance.

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

Definition at line 65 of file dt_rv_timer.c.

◆ dt_rv_timer_instance_id()

dt_instance_id_t dt_rv_timer_instance_id ( dt_rv_timer_t dt )

Get the instance ID of an instance.

Parameters

dt	Instance of rv_timer.

Returns: The instance ID of that instance.

Definition at line 72 of file dt_rv_timer.c.

◆ dt_rv_timer_irq_from_plic_id()

dt_rv_timer_irq_t dt_rv_timer_irq_from_plic_id	(	dt_rv_timer_t	dt,
		dt_plic_irq_id_t	irq )

Convert a global IRQ ID to a local rv_timer IRQ type.

Parameters

dt	Instance of rv_timer.
irq	A PLIC ID that belongs to this instance.

Returns: The rv_timer IRQ, or kDtRvTimerIrqCount.

Note: This function assumes that the PLIC ID belongs to the instance of rv_timer passed in parameter. In other words, it must be the case that dt_rv_timer_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtRvTimerIrqCount.

Definition at line 94 of file dt_rv_timer.c.

◆ dt_rv_timer_irq_to_plic_id()

dt_plic_irq_id_t dt_rv_timer_irq_to_plic_id	(	dt_rv_timer_t	dt,
		dt_rv_timer_irq_t	irq )

Get the PLIC ID of a rv_timer IRQ for a given instance.

If the instance is not connected to the PLIC, this function will return kDtPlicIrqIdNone.

Parameters

dt	Instance of rv_timer.
irq	A rv_timer IRQ.

Returns: The PLIC ID of the IRQ of this instance.

Definition at line 84 of file dt_rv_timer.c.

◆ dt_rv_timer_reg_block()

uint32_t dt_rv_timer_reg_block	(	dt_rv_timer_t	dt,
		dt_rv_timer_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of rv_timer.
reg_block	The register block requested.

Returns: The register base address of the requested block.

Definition at line 77 of file dt_rv_timer.c.

◆ dt_rv_timer_reset()

dt_reset_t dt_rv_timer_reset	(	dt_rv_timer_t	dt,
		dt_rv_timer_reset_t	rst )

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

Parameters

dt	Instance of rv_timer.
rst	Reset port.

Returns: Reset signal.
