Fig. 2 is the flowchart 2 of method of the locking farsighted frequency of CPU provided in an embodiment of the present invention to highest frequency.
Fig. 3 is the block diagram of operating system provided in an embodiment of the present invention.
Specific embodiment
As shown in Figure 1, the locking farsighted frequency of CPU provided by the invention is to the method for highest frequency, details are as follows:
Step S1, starting BIOS operation carry out CPU self-test and initialization；CPU initialization module is responsible for CPU progress self-test, just
Beginningization configuration, CPU can be worked normally, and farsighted frequency parameter configuration module is responsible for detecting CPU to the support situation of farsighted frequency function, if
It supports farsighted frequency function, opens cadence, farsighted frequency function, read CPU core number, calculate frequency parameter, configure the default of CPU frequency parameter
Value, traditional mode power management module are responsible for power management of the CPU under conventional power source management mode, carry out overclocking, primary mould
Formula power management module is responsible for power management of the CPU under primary powder source management mode, and configuration parameter carries out overclocking.BIOS is opened
When dynamic operation, the initialization such as CPU self-test, initial work are carried out, then carries out hardware check, hardware basic setup, resource allocation
Work.
Step S2, it reads CPU register and judges whether CPU supports farsighted frequency technology, if supporting, perform the next step, if not
Support, then can not lock operation, terminate operation；After CPU is worked normally, cpuid instruction is assigned to CPU, reads the deposit of CPU ability
Device, judges whether CPU supports farsighted frequency technology, if it does not, can not conduct the locking operations, terminates operation.If supporting farsighted frequency
Technology then performs the next step.
Step S3, cpu data information is obtained according to farsighted frequency technology and farsighted frequency frequency parameter value is set；Call MSR that program is set,
Cadence technical functionality is opened, cadence technical functionality is the precondition of farsighted frequency technology, then calls multi-core processing routine, opens
Open the cadence technical functionality of whole cores.Next it calls configuration space to execute program, opens farsighted frequency technology, and setting is synchronized
To multiple processors.Configuration reading program is called, cpu power control unit register is read, reads the nucleus number of CPU activation.By
It is limited in the thermal design power of CPU, the nucleus number of CPU activation is fewer, and maximum Clock Multiplier Factor is bigger, and the nucleus number of CPU activation is more, most
Big Clock Multiplier Factor is smaller, in practical application scene, needs less CPU core number, higher CPU running frequency, competence exertion maximality
It can, it is therefore desirable to according to the actual application, the nucleus number that setting CPU is activated.MSR reading program is called, farsighted frequency nucleus number limit is read
Register processed obtains CPU core number and is segmented distributed data, and data will indicate that under a certain segmentation Clock Multiplier Factor, the nucleus number that can be supported
Quantity, then farsighted frequency frequency multiplication limit register is read, it obtains Clock Multiplier Factor and is segmented distributed data, data will indicate that CPU not coactivation
The Clock Multiplier Factor numerical value of nucleus number, farsighted frequency nucleus number limit register and farsighted frequency frequency multiplication limit register are corresponding relationships, according to program
The current CPU read activates nucleus number, can calculate the maximum Clock Multiplier Factor numerical value of current farsighted frequency dynamic adjustment.Call MSR setting
The Properties Control register of maximum frequency multiplication numerical value setting to traditional mode as Clock Multiplier Factor default value, while also will by program
Maximum frequency multiplication numerical value is arranged into the Properties Control register of primary mode, including maximum performance controls register, minimum performance
Register, request Properties Control register are controlled, as Clock Multiplier Factor default value.
Step S4, the characteristic selection power management that operating system is supported according to itself is that CPU will be continuously maintained in most
High-frequency operation.The characteristic that operating system is supported according to itself selects power management, if selecting primary mode, closes
Properties Control interface is closed, allows operating system that can not adjust CPU Clock Multiplier Factor, CPU, which will be used, defaults farsighted frequency Clock Multiplier Factor, default times
Frequency coefficient is already set as maximum Clock Multiplier Factor, while remaining constant frequently outside, and outer frequency is equal to CPU operation frequency multiplied by frequency multiplication
Rate, therefore CPU will be continuously maintained in highest frequency operation at this time.If selecting traditional mode, setting cpu performance number of states is
1, energy-efficient performance state is removed, allows CPU that can only operate in maximum performance states, by maximum Clock Multiplier Factor numerical value setting to CPU
It can control in data-interface, operating system reads cpu performance control data and is arranged into farsighted frequency Clock Multiplier Factor control interface,
CPU is allowed to operate under maximum Clock Multiplier Factor, equally, outer frequency remains constant, and outer frequency is equal to CPU running frequency multiplied by frequency multiplication,
Therefore CPU will be continuously maintained in highest frequency operation at this time.
It is arranged by software, the attainable peak of farsighted frequency Technique dynamic frequency institute is locked, makes CPU continuous service most
High-frequency realizes overclocking, improves the performance of whole system far more than the rated frequency of CPU.Under the premise of improving frequency, keep
CPU stable operation is in defined power consumption, electric current, voltage and temperature range, it is ensured that CPU will not be damaged because of ultra-specification, and extension makes
With the service life, quality guarantee can be enjoyed breaking down.CPU indices are run within the specified scope, in CPU design tolerance band
It is interior, it ensures CPU operation stability, ensures the operation stability of whole system.
In this method, by software strategy, realizes overclocking capabilities, cpu performance is allowed to maximize.Auto-Sensing nucleus number, automatically
Match maximum Clock Multiplier Factor；Maximum Clock Multiplier Factor is set, adjusts operating system performance control interface, CPU is allowed persistently to keep highest
Frequency operation；Realize overclocking under the premise of, CPU indices within the specified scope, system stable operation guarantee.
