    Query {

}

The Magma Device protocol allow clients to learn about the hardware by making queries, such as device and vendor IDs, and which client drivers are supported by the device’s system driver.
To engage further with the device, clients may establish connections formed of channel pairs: a primary channel for making requests (see Primary protocol below), and a secondary channel for receiving notification messages (see Notification protocol below).

Variants

Query

On success, returns a result either in a buffer or a simple value.

Fields

query_id: QueryId

responder: DeviceQueryResponder

Connect2

Creates a connection to the device comprised of two IPC channels. The primary channel is for the Primary protocol (see below). The notification channel is used for vendor-specific messages which are sent only in the reverse (server-client) direction, typically in response to client command completion.

Fields

client_id: u64

primary_channel: ServerEnd<PrimaryMarker>

notification_channel: ServerEnd<NotificationMarker>

control_handle: DeviceControlHandle
