inteltool - a tool for dumping Intel(R) CPU / chipset configuration parameters SYNOPSIS
inteltool [-vh?grpmedPMa] DESCRIPTION
inteltool is a handy little tool for dumping the configuration space of Intel(R) CPUs, northbridges and southbridges. This tool has been developed for the coreboot project (see http://coreboot.org for details on coreboot). OPTIONS
-h, --help Show a help text and exit. -v, --version Show version information and exit. -a, --all Dump all known I/O Controller Hub (ICH) southbridge, Intel(R) northbridge and Intel(R) Core CPU MSRs. -g, --gpio Dump I/O Controller Hub (ICH) southbridge GPIO registers. -r, --rcba Dump I/O Controller Hub (ICH) southbridge RCBA registers. -p, --pmbase Dump I/O Controller Hub (ICH) southbridge PMBASE registers. -m, --mchbar Dump Intel(R) northbridge MCHBAR registers. -e, --epbar Dump Intel(R) northbridge EPBAR registers. -d, --dmibar Dump Intel(R) northbridge DMIBAR registers. -P, --pciexbar Dump Intel(R) northbridge PCIEXBAR registers. -M, --msrs Dump Intel(R) CPU MSRs.

CPUID(4) Linux Programmer's Manual CPUID(4) NAME
cpuid - x86 CPUID access device DESCRIPTION
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. The lower 32 bits of the file position is used as the incoming %eax, and the upper 32 bits of the file position as the incoming %ecx, the latter intended for "counting" eax levels like eax=4. This driver uses /dev/cpu/CPUNUM/cpuid, where CPUNUM is the minor number, and on an SMP box will direct the access to CPU CPUNUM as listed in /proc/cpuinfo. This file is protected so that it can be read only by the user root, or members of the group root. NOTES
The CPUID instruction can be directly executed by a program using inline assembler. However this device allows convenient access to all CPUs without changing process affinity. Most of the information in cpuid is reported by the kernel in cooked form either in /proc/cpuinfo or through subdirectories in /sys/devices/system/cpu. Direct CPUID access through this device should only be used in exceptional cases. The cpuid driver is not auto-loaded. On modular kernels you might need to use the following command to load it explicitly before use: $ modprobe cpuid There is no support for CPUID functions that require additional input registers. Very old x86 CPUs don't support CPUID. SEE ALSO
