HOST TO GUEST NOTIFICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240338238 titled 'HOST TO GUEST NOTIFICATION

The abstract describes a method and system for host to guest (h2g) notification using an instruction, specifically a send user inter-processor interrupt instruction. This allows for communication between a virtual device on a host machine and a virtual device driver on a guest machine.

• Instruction used for h2g notification is a send user inter-processor interrupt instruction.
• Processor includes decoder circuitry to decode and execute the instruction.
• Notification is sent from a virtual device on a host machine to a virtual device driver on a guest machine.
• Communication occurs between virtual devices on different physical processors.

Potential Applications: - Virtualization technology - Cloud computing - Server management

Problems Solved: - Facilitates communication between virtual devices on different physical processors. - Enhances efficiency in virtualized environments.

Benefits: - Improved communication between host and guest machines. - Streamlined data transfer processes. - Enhanced performance in virtualized systems.

Commercial Applications: Title: Virtualization Communication Enhancement Technology This technology can be utilized in data centers, cloud computing services, and virtual machine management software to improve communication and data transfer efficiency in virtualized environments.

Questions about the technology: 1. How does this technology improve communication between virtual devices on different physical processors? 2. What are the potential implications of this technology in cloud computing services?

Original Abstract Submitted

a method and system of host to guest (h2g) notification are disclosed. h2g is provided via an instruction. the instruction is a send user inter-processor interrupt instruction. an exemplary processor includes decoder circuitry to decode a single instruction and execute the decoded single instruction according to the at least the opcode to cause a host to guest notification from a virtual device running in a host machine on the first physical processor to a virtual device driver running on a virtual processor in a guest machine on a second physical processor.
