Emulated Devices High-Level Design

Full virtualization device models can typically reuse existing native device drivers to avoid implementing front-end drivers. ACRN implements several fully virtualized devices, as documented in this section.

• USB Virtualization
• UART Virtualization
• Watchdog Virtualization
• AHCI Virtualization
• System Timer Virtualization
• UART Emulation in Hypervisor
• RTC Emulation in Hypervisor
• Host Bridge Emulation
• AT Keyboard Controller Emulation
• Split Device Model
• Interfaces Design
• Shared Memory Based Inter-VM Communication
