msr

MSR is a software tool that allows users to display or modify x86 model-specific registers (MSRs). The program supports several syntax options for arguments, allowing for flexibility in the types of displays and modifications that can be made.

Users can choose from a variety of options when entering arguments, including displaying all MSRs, displaying an MSR with a specific number, displaying any MSRs with names that contain a given subname, displaying a specific field within an MSR, and setting an MSR or field to a specific value.

MSR also includes various options for customizing the display and modification process. These include the ability to display information only for the first CPU, display MSR names only (unless only a number is known), display and set MSR values symbolically only, display and set MSR field values symbolically only, display MSR numbers only, and various combinations of displaying and setting MSR and field values as numbers only.

Additionally, users can choose to display MSR field descriptions only or MSR field names only, rather than both. These options provide flexibility and customization for users who require specific types of displays or modifications. Overall, MSR is a powerful tool for managing x86 model-specific registers and offers a wide range of options for customization and control.
