VirtIO (Virtual I/O) is a standardized interface for virtual devices in
|
|
paravirtualized environments. NuttX implements a complete VirtIO framework
|
|
based on OpenAMP, supporting various VirtIO drivers such as VirtIO-Net,
|
|
VirtIO-Block, VirtIO-Serial, and more.
|
|
|
|
The framework supports different transport layer implementations including
|
|
VirtIO-MMIO, VirtIO-PCI, and VirtIO-Remoteproc.
