Use man pages to check command line arguments in configuration:
	man thermald
	man thermal-conf.xml

Prerequisites:
	Kernel
		Prefers kernel with
			Intel RAPL power capping driver : Available from Linux kernel 3.13.rc1
			Intel P State driver (Available in Linux kernel stable release)
			Intel Power clamp driver (Available in Linux kernel stable release)

		CONFIG_X86_MSR, so that x86 MSR can be read/write from user space to control RAPL if no RAPL powecap class driver is not present.

	Default
		If none of the above available cpufreq to control P states.

Version 0.4
- Added power clamp driver interface
- Added per cpu controls by trying to calibrate in the background to learn sensor cpu relationship
- Optimized p states and turbo states and cleaned up
- systemd and service start stop interface

Version 0.3
- Added P states t states turbo states as the cooling methods
- No longer depend on any thermal sysfs, zone cooling device by default
- Uses DTS core temperature and p/turbo/t states to cool system
- By default only will use DTS core temperature and p/turbo/t states only
- All the previous controls based on the zones/cdevs and XML configuration is only done, when activated via command line
- The set points are calculated and stored in a config file when it hits thermal threshold and adjusted based
on slope and angular increments to dynamically adjust set point


Version 0.2
- Define XML interface to set configuration data. Refere to thermal-conf.xml. This allows to overide buggy Bios thermal comfiguration and also allows to extend the capability.
- Use platform DMI UUID to index into configuration data. If there is no UUID match, falls back to thermal sysfs
- Terminate interface
- Takes over control from kernel thermal processing
- Clean up of classes.


Version 0.1
- Dbus interface to set preferred policy: "performance", "quiet/power", "disabled"
- Defines a C++ classes for zones, cooling devices, trip points, thermal engine
- Methods can be overridden in a custom class to modify default behaviour
- Read thermal zone and cooling devices, trip points etc,
- Read temprature via netlink notification or via polling configurable via command line
- Once a trip point is crossed, activate the associate cooling devices. Start with min tstate to max tstate for each cooling device.
- Based on active or passive settings it decides the cooling devices
