DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the following further elaborates on the embodiments of the present invention in detail with reference to specific embodiments and the accompanying drawings.
[0021] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are used to distinguish two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.
[0022] In one embodiment, please refer to Figure 1 As shown, the present invention provides a method 100 for power consumption management of key modules of a domestic platform, specifically including: Step 101, in response to the processor of the domestic platform receiving a power-on request for a key module, obtain the GPIO bound to the power supply of the key module and the corresponding driver loading method from the power-on request; Specifically, domestic platforms include LoongArch, FT-2000 / 4, Kunpeng, SW64, etc. The key modules refer to the modules that do not need to run in real time in domestic platforms but play an important role in the overall operation of domestic platforms. The key modules can also be called non-real-time operation modules, including communication modules (wireless communication modules, wired communication modules, etc.), computing modules (graphics processors, coprocessors, etc.), storage modules (external memories, non-volatile memories, etc.), etc. When initially designing the hardware, establish a binding relationship between the working voltage of the key module and the GPIO (General-Purpose Input / Output) of the corresponding power domain. Based on the power domain corresponding to the working voltage of the key module, establish a binding relationship between the key module and the GPIO of the corresponding power domain. The driver loading method of the key module is divided into dynamic driver loading method and static driver loading method. The dynamic driver loading method can be loaded on demand. When the key module needs to be powered on and work, load the corresponding driver loading program into the kernel to achieve dynamic driver loading; the static driver loading method is to compile the driver code into the kernel image, and the driver is loaded when the system starts and cannot be unloaded during the system operation. In the domestic server platform, the relevant modules (core hardware) of the memory controller driver can only be statically loaded, while the external storage device driver and the hot-pluggable PCIE (Peripheral Component Interconnect Express) device driver can be loaded on demand through dynamic loading.
[0023] Step 102, change the GPIO level corresponding to the power supply of the key module from the first state to the second state according to the corresponding driver loading method to start the key module to work; Specifically, when the key module is in the powered-on state, the level state of the GPIO corresponding to its power supply is high level, marked as 1. When the key module is in the powered-off state, the level state of the GPIO corresponding to its power supply is low level, marked as 0. The method further includes setting the GPIO corresponding to the power supply of the key module through the association relationship between the working voltages of several key modules and the power domains of the corresponding GPIOs. As Figure 2 shown, Figure 2It is a flowchart for starting a key module. During the initial hardware design, a binding relationship is established between the operating voltage of the key module and the GPIO of the corresponding power domain. Based on the power domain corresponding to the operating voltage of the key module, a binding relationship is established between the key module and the GPIO of the corresponding power domain. If the driver loading method of the key module is the dynamic driver loading method, then load the driver program corresponding to the key module. By modifying the values in the module_init and module_exit functions in the driver program, change the level of the GPIO bound to the power supply of the key module from low level to high level, and change the identifier from 0 to 1 to start the key module. If the driver loading method of the key module is the static driver loading method, then the driver of the key module is loaded during system operation. By pulling up the level of the GPIO bound to the power supply of the key module in the GPIO register, changing it from low level to high level, and changing the identifier from 0 to 1, start the key module.
[0024] Step 103, in response to the processor receiving a signal that the key module has completed its work, restore the level of the corresponding bound GPIO from the second state to the first state according to the corresponding driver loading method to power off the key module.
[0025] Specifically, after the key module starts, it sends a start signal to the processor. After receiving the start signal, the processor starts to monitor the working state of the key module in real time to check whether the work is completed. If the processor receives a work completion signal sent by the key module, then the processor performs a power-off operation on it. According to the corresponding driver loading method of the key module (dynamic driver loading method or static driver loading method), restore the level of the GPIO bound to the key module from the second state to the first state to power off the key module. If the driver loading method of the key module is the dynamic driver loading method, load the driver program corresponding to the key module. By modifying the values in the module_init and module_exit functions in the driver program, change the level of the GPIO bound to the power supply of the key module from high level to low level, and change the identifier from 1 to 0 to power off the key module. If the driver loading method of the key module is the static driver loading method, then the driver of the key module is loaded during system operation. By pulling down the level of the GPIO bound to the power supply of the key module in the GPIO register, changing it from high level to low level, and changing the identifier from 1 to 0, power off the key module.
[0026] The above method for power consumption management of key modules of a domestic platform is based on the working state of the key modules themselves, rather than unified management based on a fixed power consumption management strategy. Based on the corresponding driver loading method of the key modules and the GPIO corresponding to their power supply, the driver is loaded according to the corresponding driver loading method, and the power on and off of the key modules are controlled through the high and low levels of the GPIO. It can be dynamically adjusted according to the different working states of the key modules. When the key modules need to work, they are powered on, and when the work is completed, they are powered off in a timely manner, improving the efficiency of power consumption management, reducing the waste of resources for power consumption management, fully targeting the key modules for power consumption management, and improving the flexibility of power consumption management.
[0027] According to some embodiments of the present invention, the step of changing the level of the GPIO corresponding to the power supply of the key module from the first state to the second state according to the corresponding driver loading method includes: in response to the corresponding driver loading method being the dynamic loading method, loading the driver program corresponding to the key module, and changing the level of the GPIO corresponding to the key module recorded therein from the low level to the high level, so as to change from the first state to the second state. The dynamic driver loading method can be loaded on demand, saving memory. At the same time, the driver can be updated separately, which is convenient for debugging and is conducive to improving the flexibility of power consumption management.
[0028] According to some embodiments of the present invention, the step of changing the level of the GPIO corresponding to the power supply of the key module recorded therein from the low level to the high level includes: by modifying the values in the module_init and module_exit functions of the driver program, changing the level of the GPIO corresponding to the power supply of the key module from the low level to the high level.

The static driver loading method is suitable for key modules with high requirements for performance and security. It is loaded after the system starts up, passes through a complete kernel verification, and has high reliability. After that, no additional loading steps are required.
[0030] According to some embodiments of the present invention, the step of restoring the level of the corresponding bound GPIO from the second state to the first state according to the corresponding driver loading method includes: in response to the corresponding driver loading method being the dynamic loading method, loading the driver program corresponding to the key module, and changing the level of the GPIO corresponding to the power supply of the key module recorded therein from the high level to the low level, so as to restore from the second state to the first state.
[0031] According to several embodiments of the present invention, the step of restoring the GPIO level corresponding to the binding to the first state from the second state according to the corresponding drive loading method further includes: in response to the drive loading method being the static loading method, pulling down the level of the GPIO corresponding to the power supply of the key module in the GPIO register to restore it to the first state from the second state.
