Implemented Interfaces

QmiDevice implements GAsyncInitable.

Description

QmiDevice is a generic type in charge of controlling the access of multiple QmiClient objects to the managed QMI port.

qmi_device_command_full ()

void
qmi_device_command_full (QmiDevice *self,
                         QmiMessage *message,
                         QmiMessageContext *message_context,

                         GAsyncReadyCallback callback,
                         gpointer user_data);

Asynchronously sends a QmiMessage to the device.

The message will be processed according to the specific message_context given. If no context given, the behavior is the same as qmi_device_command().

If the operation is cancelled via cancellable , a QMI_PROTOCOL_ERROR_ABORTED error will be returned always. If the QMI method may be aborted, there is no guarantee that the operation is truly aborted before the error is returned so it may really happen that the operation really succeeded and the method would still return QMI_PROTOCOL_ERROR_ABORTED. In order to use abortable methods and make sure the response is the correct one, use qmi_device_command_abortable().

When the operation is finished callback will be called. You can then call qmi_device_command_full_finish() to get the result of the operation.

Parameters

self

a QmiDevice.

 

message

the message to send.

 

message_context

the context of the message.

 

timeout

maximum time, in seconds, to wait for the response.

 

cancellable

a GCancellable, or NULL.

 

callback

a GAsyncReadyCallback to call when the operation is finished.

 

user_data

the data to pass to callback function.

Finishes an operation started with qmi_device_command_full().

Parameters

                              gpointer user_data);

Asynchronously sends a QmiMessage to the device.

The message will be processed according to the specific message_context given.

If the operation is cancelled via cancellable , an abort message will be sent to the device in order to really abort the ongoing operation. The qmi_device_command_abortable() method will not finish until either a successful reply is received from the device or otherwise the command abortion is confirmed.

If a successful command response arrives before the abort is processed by the device, the operation will succeed even if cancellable has been set, so that upper layers can do whatever they need to do to properly tear down the operation.

If an error command reponse arrives before the abort is processed by the device, the operation will fail with the error returned by the device.

The QMI_PROTOCOL_ERROR_ABORTED error will only be returned as a result of this operation if the command request was truly aborted by the device, and so, the user of the method should not assume that cancelling the cancellable will always make the method return a QMI_PROTOCOL_ERROR_ABORTED error.

The build_request_fn and parse_response_fn callbacks are required in order to build the abort requests and parse the abort responses, because these are both service and client specific.

When the operation is finished callback will be called. You can then call qmi_device_command_abortable_finish() to get the result of the operation.

Parameters

self

a QmiDevice.

 

message

the message to send.

 

message_context

the context of the message.

 

timeout

maximum time, in seconds, to wait for the response.

 

abort_build_request_fn

[scope async]

abort_parse_response_fn

qmi_device_add_link ()

void
qmi_device_add_link (QmiDevice *self,
                     guint mux_id,
                     const gchar *base_ifname,
                     const gchar *ifname_prefix,
                     GCancellable *cancellable,
                     GAsyncReadyCallback callback,
                     gpointer user_data);

Asynchronously creates a new virtual network device node with a custom prefix on top of base_ifname . This allows having multiple net interfaces running on top of another using multiplexing.

If the kernel driver doesn't allow this functionality, a QMI_CORE_ERROR_UNSUPPORTED error will be returned.

The operation may fail if the given interface name is not associated to the QMI control port managed by the QmiDevice.

Depending on the kernel driver in use and the multiplexing method, the given ifname_prefix may be ignored. The user should not assume that the returned link interface name is prefixed with ifname_prefix as it may not be the case.

When the operation is finished callback will be called. You can then call qmi_device_add_link_finish() to get the result of the operation.

When using the qmi_wwan kernel driver, the configured expected kernel data format will be used to select the type of multiplexing method. If the format is QMI_DEVICE_EXPECTED_DATA_FORMAT_RAW_IP the qmi_wwan specific add_mux/del_mux operations will be used. If the format is QMI_DEVICE_EXPECTED_DATA_FORMAT_QMAP_PASS_THROUGH, the generic rmnet netlink operations will be used. No multiplexing support exists when the format is QMI_DEVICE_EXPECTED_DATA_FORMAT_802_3.

For every other kernel driver (e.g. ipa), rmnet netlink operations are assumed to be supported.

When using the qmi_wwan driver from a kernel older than v5.12, some of the multiplexing features like using QMI_DEVICE_MUX_ID_AUTOMATIC may not be fully available for programs that use ephimeral QmiDevice objects for single operations.

Parameters

self

a QmiDevice.

 

mux_id

the mux id for the link, in the [QMI_DEVICE_MUX_ID_MIN,QMI_DEVICE_MUX_ID_MAX] range, or QMI_DEVICE_MUX_ID_AUTOMATIC to find the first available mux id.

 

base_ifname

the interface which the new link will be created on.

 

ifname_prefix

the prefix suggested to be used for the name of the new link created.

 

cancellable

a GCancellable, or NULL.

 

callback

                                const gchar *base_ifname,
                                const gchar *ifname_prefix,

                                gpointer user_data);

Asynchronously creates a new virtual network device in the same way as qmi_device_add_link() does, but passing the additional flags to the kernel during the operation.

Using QMI_DEVICE_ADD_LINK_FLAGS_NONE as flags is equivalent to calling qmi_device_add_link() directly.

If the link creation with the given set of flags is unsupported by the backend, the operation may fail.

None of the flags supported are applicable when using the multiplexing support provided by the qmi_wwan kernel driver, they are only used if using the rmnet backend for link management support.

Parameters

self

a QmiDevice.

 

mux_id

the mux id for the link, in the [QMI_DEVICE_MUX_ID_MIN,QMI_DEVICE_MUX_ID_MAX] range, or QMI_DEVICE_MUX_ID_AUTOMATIC to find the first available mux id.

 

base_ifname

the interface which the new link will be created on.

 

ifname_prefix

the prefix suggested to be used for the name of the new link created.

 

flags

bitmask of QmiDeviceAddLinkFlags values to pass to the kernel when creating the new link.

                        GAsyncReadyCallback callback,
                        gpointer user_data);

Asynchronously deletes a virtual network interface that has been previously created with qmi_device_add_link().

If the kernel driver doesn't allow this functionality, a QMI_CORE_ERROR_UNSUPPORTED error will be returned.

When the operation is finished callback will be called. You can then call qmi_device_delete_link_finish() to get the result of the operation.

The QMI_DEVICE_MUX_ID_UNBOUND value may be given as mux_id if the user can guarantee that the underlying kernel support doesn't require the mux id info to delete the link. When using the qmi_wwan driver from a kernel older than v5.12, a valid mux_id is required.

Parameters

self

ifname

                             gpointer user_data);

Asynchronously deletes all virtual network interfaces that have been previously created with qmi_device_add_link() in base_ifname .

When the operation is finished callback will be called. You can then call qmi_device_delete_link_finish() to get the result of the operation.
