|
||||
|
||||
## Emulated Devices
|
||||
|
||||
- [`CMOS/RTC`] - Used to get the current calendar time.
|
||||
- [`i8042`] - Used by the guest kernel to exit crosvm.
|
||||
- [`serial`] - x86 I/O port driven serial devices that print to stdout and
|
||||
take input from stdin.
|
||||
|
||||
[`cmos/rtc`]: https://chromium.googlesource.com/chromiumos/platform/crosvm/+/refs/heads/main/devices/src/cmos.rs
|
||||
[`i8042`]: https://chromium.googlesource.com/chromiumos/platform/crosvm/+/refs/heads/main/devices/src/i8042.rs
|
||||
[`serial`]: https://chromium.googlesource.com/chromiumos/platform/crosvm/+/refs/heads/main/devices/src/serial.rs
|
||||
|
||||
## VirtIO Devices
|
||||
|
||||
- [`balloon`] - Allows the host to reclaim the guest's memories.
|
||||
- [`block`] - Basic read/write block device.
|
||||
- [`console`] - Input and outputs on console.
|
||||
- [`fs`] - Shares file systems over the FUSE protocol.
|
||||
- [`gpu`] - Graphics adapter.
|
||||
- [`input`] - Creates virtual human interface devices such as keyboards.
|
||||
- [`iommu`] - Emulates an IOMMU device to manage DMA from endpoints in the
|
||||
guest.
|
||||
- [`net`] - Device to interface the host and guest networks.
|
||||
- [`p9`] - Shares file systems over the 9P protocol.
|
||||
- [`pmem`] - Persistent memory.
|
||||
- [`rng`] - Entropy source used to seed guest OS's entropy pool.
|
||||
- [`snd`] - Encodes and decodes audio streams.
|
||||
- [`tpm`] - Creates a TPM (Trusted Platform Module) device backed by libtpm2
|
||||
simulator.
|
||||
- [`video`] - Encodes and decodes video streams.
|
||||
- [`wayland`] - Allows the guest to use the host's Wayland socket.
|
||||
- [`vsock`] - Enables use of virtual sockets for the guest.
|
||||
- `vhost-user` - VirtIO devices which offloads the device implementation to
|
||||
another process through the [vhost-user protocol].
|
||||
- [vmm side]: Shares its virtqueues.
|
||||
- [device side]: Consumes virtqueues.
