Module devices::virtio::media

Support for virtio-media devices in crosvm.

This module provides implementation for the virtio-media traits required to make virtio-media devices operate under crosvm. Sub-modules then integrate these devices with crosvm.

Structs

• ArcedMemoryMapper 🔒
  A SharedMemoryMapper behind an Arc, allowing it to be shared.
• CrosvmVirtioMediaDevice 🔒
  Implements the required traits to operate a [VirtioMediaDevice] under crosvm.
• EventQueue 🔒
  Structure supporting the implementation of VirtioMediaEventQueue for sending events to the driver.
• GuestMemoryMapper 🔒
  Newtype to implement VirtioMediaGuestMemoryMapper on GuestMemory.
• GuestMemoryMapping 🔒
  Direct linear mapping of sparse guest memory.
• GuestMemoryShadowMapping 🔒
  Copy of sparse guest memory that is written back upon destruction.
• HostMemoryMapper 🔒
  Provides the ability to map host memory into the guest physical address space. Used to implement VirtioMediaHostMemoryMapper.
• WaitContextPoller 🔒
  Newtype to implement SessionPoller on Rc<WaitContext<Token>>.
• Worker 🔒
  Worker to operate a virtio-media device inside a worker thread.

Enums

• GuestMemoryChunk 🔒
  A chunk of guest memory which can be either directly mapped, or copied into a shadow buffer.
• Token 🔒

Constants

• HOST_MAPPER_RANGE 🔒

Functions

• create_virtio_media_simple_capture_device
  Create a simple media capture device.
• create_virtio_media_v4l2_proxy_device
  Create a proxy device for a host V4L2 device.
