Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer architectures struggle to dynamically configure processor operations based on the presence of a hypervisor, leading to inefficiencies in resource management and security across different execution domains.
Innovation Solution
The implementation of a hypervisor status register that indicates the presence of a hypervisor, allowing the processor to configure its operations, such as address translation and security controls, dynamically based on this status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processor uses a fixed architecture without hypervisor awareness, then the system structure is simple, but resource management efficiency and security isolation deteriorate
Solution Approach 1:
The patent applies dynamics by making the processor configuration adaptable based on hypervisor presence. The processor dynamically switches between different operational modes (with or without hypervisor) and adjusts its behavior accordingly, allowing efficient resource management when hypervisor is present while maintaining simplicity when absent.
Solution Approach 2:
The patent changes key processor parameters such as address translation behavior, security control settings, and execution domain management based on the hypervisor status. By modifying these parameters dynamically, the processor achieves efficient resource management without requiring a completely different hardware architecture.
2Reliability
If the processor implements comprehensive security controls and address translation for hypervisor presence, then security and isolation are improved, but processing speed and system simplicity deteriorate
Solution Approach 1:
The security controls and address translation mechanisms are activated only when needed (when hypervisor is present). The processor dynamically enables or disables these security features based on the operational context, maintaining strong security isolation when required while avoiding performance overhead when not needed.
Solution Approach 2:
The patent implements partial security controls that are applied selectively based on the execution domain and hypervisor presence. Rather than applying comprehensive security measures to all operations unconditionally, the system applies security controls only where necessary, balancing security isolation with processing speed.
3Adaptability or versatility
If the processor operates without hypervisor awareness, then the system is simpler and faster, but adaptability to virtualized environments deteriorates
Solution Approach 1:
The patent makes the processor universal by enabling it to operate in multiple modes: with hypervisor, without hypervisor, in virtualized environments, and in bare-metal configurations. The processor incorporates hypervisor awareness capabilities while maintaining backward compatibility with traditional operation modes, achieving multi-functionality without requiring separate hardware designs.
Solution Approach 2:
The processor dynamically adapts its configuration based on the detected hypervisor presence and operational context. This dynamic adaptability allows the same hardware to efficiently support both virtualized and non-virtualized workloads, as well as different execution domain requirements, without requiring complex static reconfiguration.

AI summary
Systems, apparatuses, and methods related to a hypervisor status register in a computer processor are described. For example, a memory coupled to the computer processor can store instructions of routines of predefined, non-hierarchical domains. The computer processor can store a value in the hypervisor status register during a power up process of the computer system. The value stored in the hypervisor status register that identifies whether or not an operating hypervisor is present in the computer system. The computer processor can configure its operations (e.g., address translation) based on the value stored in the hypervisor status register.
