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.
A machine state register (MSR) is one of three process control registers present
in the PowerPC processor architecture. Contents. 1 Processors. 1.1 e200z3

Jun 8, 2017 ... Accessing Model Specific Registers. Each MSR that is accessed by the RDMSR
and WRMSR group of instructions is identified by a 32-bit integer. MSRs are 64-
bit wide. The presence of MSRs on your processor is indicated ...
The registers with addresses 0H, 1H, 10H, 11H, 12H, and 13H in Table B-1 are
available only in the Pentium processor. Code code that accesses registers. 0H,
1H, and 10H will run on a P6 family processor without generating exceptions ...
/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. The register access is done by opening the file and ...
IA32_MPERF MSR (E7H) increments in proportion to a fixed frequency, which is
configured when the processor is booted. ... If an Intel 64 processor has hardware
support for opportunistic processor performance operation, the power-on.
libMSR: Flexible Access to MSR registers on x86/64 Linux Systems. Modern
processors offer a wide range of control and ... libMSR requires user-level access
to /dev/cpu/X/msr to read and write MSR registers. While this is often no problem
