HOST TO GUEST NOTIFICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18574849 titled 'HOST TO GUEST NOTIFICATION

Simplified Explanation: The patent application describes a method and system for host to guest (H2G) notification using an instruction to send user inter-processor interrupt.

• H2G notification is achieved through a specific instruction.
• The instruction is a send user inter-processor interrupt instruction.
• A processor decodes and executes the instruction to trigger a host to guest notification between virtual devices on different physical processors.
• The notification is sent from a virtual device in a host machine to a virtual device driver in a guest machine.

Key Features and Innovation:

• Use of a specific instruction for host to guest notification.
• Decoding and execution of the instruction by a processor.
• Facilitating communication between virtual devices on different physical processors.

Potential Applications: The technology can be applied in virtualized environments to enhance communication between host and guest machines.

Problems Solved:

• Facilitates efficient communication between virtual devices.
• Enables seamless interaction between host and guest machines.

Benefits:

• Improved performance in virtualized environments.
• Enhanced synchronization between host and guest machines.

Commercial Applications: Potential commercial applications include virtualization software, cloud computing platforms, and data centers.

Prior Art: Readers can explore prior art related to inter-processor communication in virtualized environments.

Frequently Updated Research: Stay updated on advancements in inter-processor communication in virtualized systems for potential improvements in H2G notification technology.

Questions about Host to Guest Notification: 1. What are the key components involved in H2G notification technology? 2. How does H2G notification technology impact the efficiency of virtualized environments?

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.
