What is MSR module?

What is MSR module?

A model-specific register (MSR) is any of various control registers in the x86 instruction set used for debugging, program execution tracing, computer performance monitoring, and toggling certain CPU features.

What are MSR used for?

Mortgage servicing rights (MSR) refer to a contractual agreement in which the right to service an existing mortgage is sold by the original mortgage lender to another party that specializes in the various functions involved with servicing mortgages.

What is MSR virtualization?

MSRs are virtualized or emulated by the Virtual Machine Monitor. Generally speaking, an MSR read or write will trap into the VMM/hypervisor so it can give the correct response (newer processors contain features such as MSR bitmaps for Intel’s Virtual Machine eXtensions which specify the MSRs that do this).

What is MSR safe?

The msrsave utility provides a mechanism for saving and restoring MSR values based on entries in the allowlist. To restore MSR values, the register must have an appropriate writemask. Modification of MSRs that are marked as safe in the allowlist may impact subsequent users on a shared HPC system.

What is Dev CPU?

DESCRIPTION top. /dev/cpu/CPUNUM/msr provides an interface to read and write the model-specific registers (MSRs) of an x86 CPU. CPUNUM is the number of the CPU to access as listed in /proc/cpuinfo.

What is an Lstar MSR?

MSR – Model Specific Registers LSTAR contains the 64bit virtual address in which the instruction pointer is changed to after the syscall instruction is executed. FMASK contains a mask where bits that are set in the mask are cleared in EFLAGs when the syscall instruction is executed.

What does MSR stand for?


Acronym Definition
MSR Mortgage Service Rights (mortgage banking industry)
MSR Management Systems Review
MSR Monthly Status Review
MSR Minimum Sustaining Rate

What is a MSR reader?

A magnetic stripe reader (also referred to as a ”magstripe reader”) is a hardware device that “reads” the information that has. been encoded on the magnetic stripe on the back of a plastic card. The stripes may include information like access privileges, account numbers, or other cardholder details.

How do I disable HVCI in Windows 10?

After logging in to Windows RE, you can turn off HVCI by renaming or deleting the SIPolicy. p7b file from \Windows\System32\CodeIntegrity\ and then restart your device.

How do you clean MSR pots?

What’s the best way to wash MSR cookware? All components except aluminum cookware are dishwasher safe. We recommend using a liquid detergent. Aluminum cookware should be hand-washed to prevent damage to the cookware’s surface.

How do I read my CPUID?

How To Read CPUID Instruction For Each CPU on Linux With x86info and cpuid Commands

  1. lscpu command – Show information on CPU architecture.
  2. x86info command – Show x86 CPU diagnostics.
  3. cpuid command – Dump CPUID information for each CPU. This is the closet tool to CPU-Z app on Linux.

What is CPUID in Linux?

CPUID provides an interface for querying information about the x86 CPU. This device is accessed by lseek(2) or pread(2) to the appropriate CPUID level and reading in chunks of 16 bytes. A larger read size means multiple reads of consecutive levels.
