Description
Technical field
The invention belongs to technical field of power management, specifically, being related to a kind of operation system for power supply dormancy mechanism
System and hardware platform exchange method.
Background technology
Domestic series processors of soaring include multiple models, including the 1500A that soars, soar 2000,2000+ that soars etc..It adopts
Computer platform with domestic series processors of soaring includes a variety of different forms, including notebook, server, all-in-one machine
Deng.
Domestic series processors of soaring can all integrate a GPIO (universal input/output) module, which supports multiple
GPIO port, these GPIO ports can be used for realizing some spies by soar platform computer hardware or operating system design personnel
Fixed purpose or function, for example, cycle power function or some hardware module status indicator lamp etc..Current multiple ends GPIO
Mouth is not fully used, and is had many all idle unused.One can be selected to leave unused unused GPIO to realize that power management is stopped
The software and hardware interactive function of dormancy mechanism.
Power management is an important mechanisms of computer system, and the electrical energy that it can reduce computer system disappears
Consumption, improves the Energy Efficiency Ratio of computer system, to reduce use cost, generates huge economic and social benefit.
Electric power management mechanism includes multiple functions module, including power management etc. when suspend mode, sleep and operation, specifically such as
Under：
(1) the execution context of operating system preserves in memory, when computer enters suspend mode shape when suspend mode refers to suspend mode
When state, not all hardware component has all broken power supply, and memory and the hardware component for waking up computer are in activity
State, CPU is not also fully powered-off but is in a kind of low-power consumption mode, can return to activity at any time when receiving wake-up signal
State.The advantages of suspend mode is exactly the special block of speed waken up；
(2) operating system context preserves in a hard disk when sleep refers to sleep, when computer enters sleep state, meter
The electricity of all components of calculation machine is all broken, and electric quantity consumption is approximately zero at this time.When needing to wake up, computer is restarted, is entered
After system, it can be loaded from hard disk again and restore to execute context；
(3) power management refers to power management of the computer system in normal work when running, and computer system is just
It is not that each component is working simultaneously, for example possible network interface card now may be idle, at this moment can reduce net often when work
The power consumption of card, to the electric quantity consumption of entire computer.
Suspend mode is different from sleep, and sleep is unified power-off during normal startup and shutdown, and suspend mode needs individually
The power supply of some or multiple components is broken, while other component being kept to be in active state.That is, into suspend mode shape is entered
To two parts involved in state and the whole flow process normally executed from dormant state recovery：Software flow and hardware pipeline.Wherein,
Software flow is primarily referred to as being preserved and recovered the execution context of operating system, including the freezing of all processes, memory mirror
Make and preserve etc.；Hardware pipeline is primarily referred to as power-off and the power up of each hardware component.
It can lead to there are one hardware component such as embedded controller (Embeded Controller, EC) on usual computer
Lower electric sequential when electrifying timing sequence and the closing of control computer startup is crossed, power supply sequential and some letters of computer can be managed
Single peripheral hardware.Therefore, the powering down and up action of hardware component power supply is controlled in suspend mode to be completed by EC.
Feiteng processor follows ARM64 frameworks, supports the psci power management specifications of CPU, is ordered when sending psci to CPU
When enabling, CPU can enter the dormant state of low-power consumption mode, consume less electricity, just when CPU receives any interrupt signal
It can terminate low-power consumption mode, into normal mode of operation, execute software program.Although Feiteng processor platform can use psci
Order carrys out the power supply of management processor, but psci ordering norms is not provided with the power management function of peripheral hardware.Therefore, be
Feiteng processor platform realizes sleep mode, other than using psci orders to carry out the power supply of management processor, it is necessary to can
The power supply of closing and enabled peripheral hardware.
Although there is ripe electric power management mechanism, using a kind of standard on existing x86 architecture processors platform
The power supply of peripheral hardware is closed and enabled to ACPI Specification, sends commands to processor register realize the disconnected of processor by ACPI
Electric and upper Electricity Functional, but this set of common mechanism is being soared on platform and is being not suitable for.
Chinese invention patent " a method of realizing standby, suspend mode and wake-up in domestic Feiteng processor " (application number
CN201410167068.9), a kind of side realizing standby, suspend mode and wake-up in domestic Feiteng processor of the disclosure of the invention
Method is related to field of computer information security.Operating system of the present invention and CPU are sent out by SMBUS agreements to programmable control chip
Standby, suspend mode power management is executed after sending standby, sleep operation order, programmable control chip to be connected to order.Although the hair
It is bright to realize power management between operating system and CPU by introducing programmable control chip, but exist with the difference of the present invention
In：There is no consider using the GPIO port to leave unused in Feiteng processor, but by being fully introduced into a PLC technology
Chip realizes power management sleep mode, increases development difficulty, and in the exchange method of operating system and hardware platform
On, the two is also different.
Chinese invention patent " control device and method of the CPU power consumption under platform of soaring " (application number
CN201710082179.3), the control device of the CPU power consumption under a kind of platform of soaring of the disclosure of the invention, including：It soars processing
Device, there are three GPIO interfaces for configuration；Programmable controller is connect by three GPIO interfaces with Feiteng processor, processing of soaring
Standby, suspend mode and high load condition are sent to programmable controller by device by GPIO interface；Analog switching circuit, including respectively
Three switching channels of series resistance, programmable controller control the break-make of three switching channels；Power-supply controller of electric, power supply control
Three feedback divider resistances of device processed correspond to three concatenated resistance of switching channels respectively, and power-supply controller of electric is corresponded to according to resistance value
Export scheduled voltage.Although the invention utilizes programmable controller, is realized on Feiteng processor platform and reduce CPU power consumption
Control method, but with the present invention difference lies in：By using in Feiteng processor leave unused three GPIO ports, in conjunction with
One programmable control chip is come the operating system and hardware platform realizing power management sleep mode, but proposed in the present invention
Exchange method it is more simple, only need a GPIO that can complete corresponding function, workload is small, realizes simple.
