>Description:
This kernel module provides access to i386/amd64 CPUs MSR (Model Specific
Register) registers and cpuid info through /dev/cpu%d devices, where %d
corresponds to cpu number.

It can be used with x86info to retrive information available from MSR registers.

NOTE: amd64 was not tested yet, do it, please, and report on success/failure.

X=============================================================================
X
XCPU kernel module was installed.
X
XTo load it, issue
X
X% kldload cpu
X
XThen you can access MSR registers or cpuid info via /dev/cpu%d or using
X3d-party programs, e.g. x86info.
X
XNOTE! DANGER! This module was not yet propely tested, and amd64 support
Xwas not tested at all. It's currently for development/testing only.
XDon't use on productions systems!
X
XPlease, report any problems to maintainer. Thanks!
