Data Structure Documentation

dif_rv_plic

struct dif_rv_plic

A handle to rv_plic.

This type should be treated as opaque by users.

Definition at line 38 of file dif_rv_plic_autogen.h.

Data Fields
mmio_region_t	base_addr	The base address for the rv_plic hardware registers.
dt_rv_plic_t	dt	The instance, set to kDtRvPlicCount if not initialized through dif_rv_plic_init_from_dt.

Typedef Documentation

dif_rv_plic_t

typedef struct dif_rv_plic dif_rv_plic_t

A handle to rv_plic.

This type should be treated as opaque by users.

Enumeration Type Documentation

dif_rv_plic_alert

enum dif_rv_plic_alert

A rv_plic alert type.

Enumerator
kDifRvPlicAlertFatalFault	This fatal alert is triggered when a fatal TL-UL bus integrity fault is detected.

Definition at line 99 of file dif_rv_plic_autogen.h.

Function Documentation

dif_rv_plic_alert_force()

OT_WARN_UNUSED_RESULT dif_result_t dif_rv_plic_alert_force	(	const dif_rv_plic_t *	rv_plic,
		dif_rv_plic_alert_t	alert )

Forces a particular alert, causing it to be escalated as if the hardware had raised it.

Parameters

rv_plic	A rv_plic handle.
alert	The alert to force.

Returns

The result of the operation.

Definition at line 63 of file dif_rv_plic_autogen.c.

dif_rv_plic_get_dt()

OT_WARN_UNUSED_RESULT dif_result_t dif_rv_plic_get_dt	(	const dif_rv_plic_t *	rv_plic,
		dt_rv_plic_t *	dt )

Get the DT handle from this DIF.

If this DIF was initialized by dif_rv_plic_init_from_dt(dt, ..) then this function will return dt. Otherwise it will return an error.

Parameters

	rv_plic	A rv_plic handle.
[out]	dt	DT handle.

Returns

kDifBadArg if the DIF has no DT information, kDifOk otherwise.

Definition at line 53 of file dif_rv_plic_autogen.c.

dif_rv_plic_init()

OT_WARN_UNUSED_RESULT dif_result_t dif_rv_plic_init	(	mmio_region_t	base_addr,
		dif_rv_plic_t *	rv_plic )

Creates a new handle for a(n) rv_plic peripheral.

This function does not actuate the hardware.

Parameters

	base_addr	The MMIO base address of the rv_plic peripheral.
[out]	rv_plic	Out param for the initialized handle.

Returns

The result of the operation.

DEPRECATED This function exists solely for the transition to dt-based DIFs and will be removed in the future.

Definition at line 26 of file dif_rv_plic_autogen.c.

dif_rv_plic_init_from_dt()

OT_WARN_UNUSED_RESULT dif_result_t dif_rv_plic_init_from_dt	(	dt_rv_plic_t	dt,
		dif_rv_plic_t *	rv_plic )

Creates a new handle for a(n) rv_plic peripheral.

This function does not actuate the hardware.

Parameters

	dt	The devicetable description of the device.
[out]	rv_plic	Out param for the initialized handle.

Returns

The result of the operation.
