Detailed Description

IPC service static VRINGs API.

Macro Definition Documentation

MEM_ALIGNMENT

#define MEM_ALIGNMENT   CONFIG_IPC_SERVICE_STATIC_VRINGS_MEM_ALIGNMENT

#include <zephyr/ipc/ipc_static_vrings.h>

Memory alignment.

This should take into account the cache line if the cache is enabled, otherwise it should be naturally aligned to the machine word size.

VRING_COUNT

#define VRING_COUNT   (2)

#include <zephyr/ipc/ipc_static_vrings.h>

Number of used VRING buffers.

Typedef Documentation

ipc_notify_cb

ipc_notify_cb

#include <zephyr/ipc/ipc_static_vrings.h>

Define the notify callback.

This callback is defined at instance level and it is called on virtqueue notify.

Parameters

vq	Virtqueue.
priv	Priv data.

Function Documentation

ipc_static_vrings_deinit()

int ipc_static_vrings_deinit	(	struct ipc_static_vrings *	vr,
		unsigned int	role
	)

#include <zephyr/ipc/ipc_static_vrings.h>

Deinitialise the static VRINGs.

Deinitialise VRINGs and Virtqueues of an OpenAMP / RPMsg instance.

Parameters

vr	Pointer to the VRINGs instance struct.
role	Host / Remote role.

Return values

0	If successful.
Other	errno codes depending on the OpenAMP implementation.

ipc_static_vrings_init()

int ipc_static_vrings_init	(	struct ipc_static_vrings *	vr,
		unsigned int	role
	)

#include <zephyr/ipc/ipc_static_vrings.h>

Init the static VRINGs.

Init VRINGs and Virtqueues of an OpenAMP / RPMsg instance.

Parameters

vr	Pointer to the VRINGs instance struct.
role	Host / Remote role.

Return values

-EINVAL	When some parameter is missing.
-ENOMEM	When memory is not enough for VQs allocation.
0	If successful.
Other	errno codes depending on the OpenAMP implementation.
