Detailed Description
The principles and spirit of the present application will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present application and are not intended to limit the scope of the present application in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The technical scheme of the present application is further elaborated below with reference to the drawings and specific embodiments.
Fig. 1 shows a schematic implementation flow chart of a control method according to an embodiment of the present application.
Referring to fig. 1, the control method in the embodiment of the present application at least includes the following operation flows: operation 101, obtaining output power of a power module of an electronic device; operation 102, obtaining attribute information of a first power consumption module of the electronic device, wherein a power limit value of the first power consumption module is adjustable; operation 103, obtaining input power required for maintaining the operation of the second power consumption module of the electronic device; in operation 104, a first power limit value required for maintaining the operation of the first power consumption module is determined according to the output power of the power supply module, the attribute information of the first power consumption module, and the input power for maintaining the operation of the second power consumption module, and the input power required for maintaining the operation of the first power consumption module is controlled not to exceed the first power limit value.
In operation 101, an output power of a power module of an electronic device is obtained.
In this embodiment of the present application, the output power of the power supply module may be determined by obtaining the device identification of the power supply module and then determining the output power of the power supply module according to the device identification.
In this embodiment of the present application, the power module may be an adapter or a battery for an electronic device.
In operation 102, attribute information of a first power consumption module of the electronic device is obtained, and a power limit value of the first power consumption module is adjustable.
In this embodiment of the present application, the first power consumption module may be a CPU, and a power limit of the CPU may be adjustable. Here, the attribute information of the first power consumption module may include an ID of the CPU, a value of PL2 of the CPU determined based on the ID of the CPU, the Core (Core) number of the CPU, and the like.
In this embodiment of the present application, the first Power Limit value required for maintaining the operation of the first Power consumption module may be L2 (Power Limit 2, power Limit, 2 representing the level of the Power Limit) of the CPU. Here, the power limit of the CPU is described simply by using a general purpose definition method, and the power limit of the CPU may have 4 levels, where PL1 is rated power consumption, PL2 is maximum power consumption, and PL3 or PL4 is limit power consumption, and only PL4 may be disposed and PL3 may not be disposed for small electronic devices such as a notebook. Specifically, PL1 is defined as a default TDP (Thermal Design Power, heat dissipation design power consumption) of the CPU, and when the power consumption of the CPU is within the range of PL1, the operation of the CPU is not limited. When the power consumption of the CPU reaches PL2, the power consumption of the CPU exceeds the range of TDP, and the CPU automatically adjusts the main frequency of the CPU according to the current task amount, so that the CPU can perform maximum performance full load operation when the CPU can re-task. The CPU can maintain the continuous operation time of up to 100 seconds under the power consumption of PL2, and then the CPU is limited in operation frequency until the power consumption of the CPU is restored to be within PL 1. When the power consumption of the CPU reaches PL3 and PL4, the power consumption of the CPU reaches a higher power consumption state, and only about 10ms of running time can be maintained, but the CPU is disabled by default, and not all electronic devices can be manually disabled, so that the CPU is insurmountable power consumption peak beyond PL 4. Therefore, the CPU in the present application has PL2 as the power limit value. The PL2 of the CPU may be configured according to the output power of the power supply module of the electronic apparatus, the power of the graphic card, and the like.
In this embodiment of the present application, the first power consumption module has a multi-processing chip, for example: a CPU with multiple cores. The attribute information of the first power consumption module further includes the number of cores and rated input power of the first power consumption module.
In operation 103, an input power required for maintaining operation of the second power consumption module of the electronic device is obtained.
The second power consumption module may include a module connected through PCIe (serial board card), for example: display cards and network cards of electronic devices, and the like.
In this embodiment of the present application, the board identifier of the serial board may be detected, and the input power for maintaining the operation of the module connected to the serial board may be determined according to the board identifier, so as to obtain the input power required for maintaining the operation of the second power consumption module of the electronic device.
In operation 104, a first power limit value required for maintaining the operation of the first power consumption module is determined according to the output power of the power supply module, the attribute information of the first power consumption module, and the input power for maintaining the operation of the second power consumption module, and the input power required for maintaining the operation of the first power consumption module is controlled not to exceed the first power limit value.
In this embodiment of the present application, the attribute information of the first power consumption module includes a rated input power of the first power consumption module. Correspondingly, the device identifier of the first power consumption module can be obtained, the rated input power of the first power consumption module is determined according to the device identifier of the first power consumption module, the device identifier of the second power consumption module is obtained, the input power of the second power consumption module is determined according to the device identifier of the second power consumption module, and the first power limit value required for maintaining the operation of the first power consumption module is further determined according to the output power of the power supply module, the rated input power of the first power consumption module and the input power for maintaining the operation of the second power consumption module.
For example, the first power consumption module is a CPU of the electronic device, and the second power consumption module includes a graphics card GPU of the electronic device. Accordingly, after obtaining the CPU identifier of the CPU, the rated power of the CPU may be determined according to the CPU identifier. After the board identifier of the serial board PICE is obtained, the input power for maintaining the operation of the modules such as the display card connected with the serial board can be determined according to the board identifier. Thus, the first power limit value required for maintaining the operation of the first power consumption module can be determined further based on the output power of the power supply module, the rated input power of the first power consumption module, and the input power for maintaining the operation of the second power consumption module.
In this embodiment of the present application, taking the first power consumption module as the CPU of the electronic device again, where the second power consumption module includes the graphics card GPU of the electronic device as an example, the first power consumption of the CPU may be determined according to a first mapping between the rated power consumption of the CPU and the set power consumption of the CPU under the preset power consumption of the power supply device. And determining a first power limit value of the maximum power consumption of the CPU according to a second mapping between the rated power consumption of the display card and the CPU set power consumption under the preset first power consumption.
In this embodiment of the present application, the communication lines for supporting the operation of the first power consuming module are different from the communication lines for supporting the operation of the second power consuming module.
For example, the first power consumption module is a CPU of the electronic device, and the second power consumption module includes a graphics card GPU of the electronic device. The CPU may be configured and adjusted in the BIOS option of the electronic device. Whereas GPUs need to be connected to PCIe, do not have FW (firmware) debug interfaces similar to BIOS, and can only obtain relevant information through SMBus of PCIe, so adjustable options cannot be configured in BIOS to adjust GPU parameters.
In this embodiment of the present application, the output power of the power module of the electronic device, the attribute information of the first power consumption module, and the input power required for maintaining the operation of the second power consumption module of the electronic device are also obtained in response to the electronic device start-up request. And comparing the output power of the power supply module, the attribute information of the first power consumption module and the input power for maintaining the second power consumption module to work with a pre-stored power limit value to obtain a comparison result. Further, if the comparison result shows that the output power of the power supply module, the attribute information of the first power consumption module and the input power for maintaining the operation of the second power consumption module are consistent with the pre-stored power limit value, the operation is performed with the pre-stored power limit value. And if the comparison result shows that the output power of the power supply module, the attribute information of the first power consumption module and the input power for maintaining the operation of the second power consumption module are inconsistent with the pre-stored power limit values, adjusting the first power limit value required for maintaining the operation of the first power consumption module.
In this embodiment of the present application, the pre-stored power limit value may be an initial default value of the first power consumption module of the electronic device or a first power limit value stored after the previous adjustment of the first power limit value of the first power consumption module of the electronic device.
For example, when the power key of the electronic device is triggered, during the startup process of the BIOS, the output power of the power module of the electronic device, the attribute information of the CPU, and the input power required for maintaining the operation of the power consumption module configured on the PICe, such as the graphics card of the electronic device, are first obtained. If the comparison result shows that the output power of the power supply module, the attribute information of the CPU, and the input power required for maintaining the operation of the power consumption module configured on the PICe, such as the display card of the electronic device, are consistent with the output power of the power supply module of the electronic device detected in the previous BIOS start-up process, the attribute information of the CPU, and the input power required for maintaining the operation of the power consumption module configured on the PICe, such as the display card of the electronic device, the output power of the power supply module of the electronic device, the attribute information of the CPU, and the input power required for maintaining the operation of the power consumption module configured on the PICe, such as the display card of the electronic device, are not changed, the value of PL2 of the CPU determined in the previous BIOS start-up process can be maintained unchanged. If the electronic device is a new device, in the process of starting the BIOS for the first time, the value of PL2 of the CPU may be set to an initial default value of the electronic device when the electronic device leaves the factory.
In this embodiment of the present application, before obtaining the attribute information of the first power consumption module of the electronic device, a chassis identifier is further obtained, and a chassis type of the electronic device is determined according to the chassis identifier. And under the condition that the type of the chassis of the electronic equipment is the first type, determining a first power limit value required for maintaining the operation of the first power consumption module, and controlling the input power required for maintaining the operation of the first power consumption module not to exceed the first power limit value. And under the condition that the type of the case of the electronic equipment is the second type, controlling the input power required for maintaining the operation of the first power consumption module not to exceed a second power limit value, wherein the volume of the case of the first type is smaller than that of the case of the second type, the first power limit value is smaller than or equal to the second power limit value, and the second power limit value is prestored in a storage module of the electronic equipment.
Specifically, the first type of chassis identifier may be an SFF (small form factor) or a uSFF (ultra small form factor) electronic device, for example: a small desktop or notebook computer. The second type of chassis may be a conventional desktop or workstation, etc. For models in which the output power of the power supply module is limited and the configuration is diversified, the power limitation of the CPU must be reasonably limited. Accordingly, the chassis type of the electronic device of the SFF or the uSFF may be determined as the first type herein.
The first type of chassis and the second type of chassis are relative concepts, and the above description of the first type of chassis and the second type of chassis is exemplary, and is not limited to the first type and the second type, and may be set as needed in a specific use process.
The main board identification is obtained according to the main board, and the chassis volume suitable for the main board is determined based on the main board identification, so that the size of the chassis volume can be further determined, and whether the condition of the small chassis is met or not is determined according to the size of the chassis volume.
In this embodiment of the present application, the second power limit may be an initial default value of the first power consumption module of the electronic device or a first power limit stored after the previous adjustment of the first power limit of the first power consumption module of the electronic device. For example: the second power limit may be a default PL2 value of the CPU of the electronic device, or may be a PL2 value stored after the previous adjustment of the PL2 value of the CPU of the electronic device.
In this embodiment of the present application, when the determination result shows that at least one of the output power of the power supply module, the attribute information of the first power consumption module, and the input power for maintaining the operation of the second power consumption module is changed, the first power limit is adjusted according to the updated output power of the power supply module, the attribute information of the first power consumption module, and the input power for maintaining the operation of the second power consumption module, and the input power required for maintaining the operation of the first power consumption module is controlled not to exceed the first power limit.
Specifically, when the determination result shows that at least one item of configuration information of hardware configuration such as output power of a power supply module of the electronic device, attribute information of the CPU, and input power required for maintaining operation of a power consumption module configured on the PICe, such as a display card of the electronic device, is changed, the PL2 value of the CPU may be adjusted according to the output power of the power supply module of the electronic device, the attribute information of the CPU, and the input power required for maintaining operation of the power consumption module configured on the PICe, such as the display card of the electronic device, and the input power required for maintaining operation of the CPU is controlled not to exceed the adjusted PL2 value of the CPU.
In this embodiment of the present application, it may be determined whether the first power limit needs to be adjusted according to the motherboard identifier of the electronic device and the output power of the power module. The determination may also be made based on a relationship between the original first power limit of the first power consuming module and the output power of the power source module: whether the power of the equipment connected with the serial board card needs to be detected or not; and whether the first power limit value of the first power consumption module is required to be adjusted according to the detected power of the equipment connected with the serial board card.
Specific application examples of the control method according to the embodiment of the present application may be described in detail herein.
Fig. 2 shows a schematic implementation flow chart of a specific application example of the control method according to the embodiment of the present application.
Referring to fig. 2, a specific application example of the control method in the embodiment of the present application at least includes the following operation flows: in the process of triggering a power key of the electronic equipment and starting the system, the following four steps of automatic screening and PL2 value distribution operation of the CPU are executed through the BIOS:
since the control method for the first power limit value of the first power consumption module may be configured in the BIOS system file applicable to a plurality of types of electronic devices, it is not necessary to control the PL2 value of the CPU for some types of electronic devices. Therefore, here, it is possible to configure in the BIOS file a setting according to the setting field to show whether or not the current electronic device needs to control the PL2 value of the CPU. For an electronic device that needs to control the PL2 value of the CPU, the following operations are performed:
1. the next execution is determined by obtaining the PSU ID.
For example, PSU model 380W, 310W, or other set power may be identified by a Powper Meter PIN.
2. And determining the next execution content by acquiring the chassis model.
Taking the PSU model of the electronic device as an example, here, it is further determined whether the electronic device is an SFF-type chassis. If so, the operation for controlling the PL2 value of the CPU is continued. If not, no operation for controlling the PL2 value of the CPU is performed.
For example, the control method for the first power limit value of the first power consumption module may be configured in the BIOS system file applicable to the electronic devices of multiple chassis types, and the PL2 value of the CPU does not need to be controlled for some of the chassis types of electronic devices. In the case where it is determined that the current box type is a box type that does not require control of the PL2 value of the CPU, other operations may be performed to set other parameters of the electronic apparatus without performing operations for controlling the PL2 value of the CPU.
3. The next execution is determined by obtaining the CPU model.
By way of example, screening and assignment of PL2 values may be accomplished herein by obtaining a CPU ID. The screening and distribution of the set rounds can be configured according to actual needs. Two rounds of screening and dispensing are configured during this operation in this embodiment of the present application. Referring back to the electronic device in which the output power of the PSU is 380W and the chassis is of the SFF chassis type, it is first determined whether the rated power of the CPU is 125W. If the rated power of the CPU is 125W, setting the PL2 value of the CPU according to the preset mapping of the rated power of the CPU and the PL2 value of the CPU.
4. Detecting PCIe ID determines further decisions on screening and allocation schemes of PL2 values by CPU, thereby completing automatic detection and PL2 values of CPU.
For example, a plurality of PL2 setting schemes of the CPU may be preconfigured in advance according to the type of the cabinet of the electronic apparatus, the output power of the power supply module, the rated power of the CPU, and the like, for example:
the chassis type of the electronic equipment is P350 SFF, the CPU is a single-core CPU with the rated power of 65W, the output power of the power supply module PSU is 380W, the display card type is NVIDIA A2000 GFX, and the PL2 value of the CPU is configured according to the worst basis of other modules of the electronic equipment, namely, larger input power for maintaining the operation of other power consumption modules of the electronic equipment is preset.
The actual Power consumption Power-1 of the CPU is 65W, namely PL1/65W and PL2/264W of the CPU, and the total loss of the electronic device is assumed to be 15%, namely 85% of the rated Power of the PSU can be converted and utilized by a plurality of Power consumption modules of the electronic device.
The input Power-2 for maintaining graphics NVIDIA A2000 GFX operation is 70W.
The input Power-3 for maintaining operation of the other Power consuming modules of the chassis type P350 SFF electronic device is 90W.
Thus, the predicted total power consumption of the plurality of power consuming modules of the electronic device is 264 w+70w+90w=424W. The PSU here has a rated power consumption of 380W.
Based on the above determination, the PL2 value of the CPU can be set as:
(264W-(424W-380W))*85％＝187W。
therefore, the control method of the embodiment replaces a large amount of complex T3 BOM limiting work by the automatic detection action in the simple BIOS starting process, and has simple error detection mode and extremely high reliability. And the huge amount of work of two-stage checking of BIOS code value checking and T3 BOM rule can be effectively avoided. The PL2 value control method of the CPU has simple adjustment mode and high flexibility, can be rapidly configured according to the CPUs, the GPUs, the PSUs and the like of different products, effectively avoids the situation that the actual power consumption of the device configuration of the user-defined collocation of the electronic device exceeds the rated power consumption of the PSU, and accordingly avoids the system restarting problem of the electronic device.

Therefore, the output power of the power supply module of the electronic equipment, the attribute information of the first power consumption module and the input power for maintaining the second power consumption module to work are obtained, and the first power limit value of the first power consumption module with the adjustable power limit value is automatically adjusted according to the parameters of the electronic equipment. On the premise of meeting the performance requirements of the electronic equipment, the situation that the actual power consumption exceeds the output power which can be actually output by the power supply module in the use process of the self-defined configured or built electronic equipment is effectively avoided.
