OpenLMI Hardware information
============================
OpenLMI Hardware provider contains hardware information, it does not
implement any methods. List of provided information divided by DMTF profiles
can be found below.

CPU Profile
-----------
CPU Profile provides information about CPU and associated cache:

* Processor

  - Number of CPUs, cores, threads
  - Model
  - Clock and FSB speeds
  - Data and Address width
  - Architecture
  - Flags
  - Family
  - Stepping
  - FRU data (Manufacturer, Model, Serial Number, Part Number)

* Processor Cache

  - Level
  - Size
  - Type (Data / Instruction / Unified)

Used Resources
^^^^^^^^^^^^^^
* dmidecode program *[from dmidecode package]*
* lscpu program *[from util-linux package]*
* /proc/cpuinfo file
* /sys/devices/system/cpu/* files

System Memory Profile
---------------------
System Memory Profile provides information about system memory and slots:

* Memory

  - Size
  - Speed (in both MHz and ns)
  - Size of standard memory page
  - All supported sizes of huge pages
  - Current state of transparent huge pages [Unsupported, Never, Madvise, Always]
  - Detection of NUMA layout

* Memory slots + modules

  - Number of slots and modules
  - In which slots are modules plugged in
  - Size of modules
  - Speed of modules
  - Data and Total width

Physical Asset Profile
----------------------
Physical Asset Profile provides basic information about physical assets
in system, usually with FRU data, currently for following hardware
(with associations):

* System chassis
* Baseboard (motherboard)
* Chassis ports (USB, LAN, VGA..)
* Chassis slots (Media card slot, Express card slot..)
* Pointing devices on chassis (Touch pad, Track point..)
