Struct VirtioSoundProxy

pub struct VirtioSoundProxy { /* private fields */ }

Implementations

impl VirtioSoundProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.virtualization.hardware/VirtioSound.

pub fn take_event_stream(&self) -> VirtioSoundEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn configure_queue( &self, queue: u16, size: u16, desc: u64, avail: u64, used: u64, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Configure a queue for the device. This specifies the size and the guest physical addresses of the queue: desc, avail, and used.

pub fn notify_queue(&self, queue: u16) -> Result<(), Error>

Notify a queue for the device. Primarily used for black-box testing.

pub fn ready( &self, negotiated_features: u32, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Ready a device. This provides the set of negotiated_features that the driver and device have agreed upon.

pub fn start( &self, start_info: StartInfo, enable_input: bool, enable_verbose_logging: bool, ) -> QueryResponseFut<(u32, u32, u32, u32), DefaultFuchsiaResourceDialect>

Start the sound device. The response contains the device’s expected static configuration.

• request start_info basic info to start the device
• request enable_input whether audio input (capture) should be enabled
• request enable_verbose_logging whether verbose logging should be enabled

• response features supported features
• response jacks the virtio_snd_config.jacks value to advertise
• response streams the virtio_snd_config.streams value to advertise
• response chmaps the virtio_snd_config.chaps value to advertise
