example 2

[0102] In actual implementation, the adjustment of the fan speed may not depend on the adjustment of the processor frequency, for example, when the ambient temperature of the device is higher than the preset ambient temperature threshold, or the fan power consumption exceeds the preset fan power consumption threshold adjust the fan speed.

[0103] In this optional solution, the out-of-band system adjusts the fan speed when it determines that the fan speed needs to be adjusted. The specific implementation has the following two solutions:

[0104] Solution 1. The out-of-band system determines whether the fan speed needs to be adjusted according to the current temperature of the specific device and the junction temperature of the specific device, and adjusts the fan speed when it is determined that the fan speed needs to be adjusted;

[0105] Solution 2: The out-of-band system determines the target speed of the fan according to the junction temperature of the specific device and ...

[0144] Example 1: The out-of-band system obtains the processor usage and adjusts the processor frequency

[0145] image 3 It is a schematic diagram of a method for obtaining processor occupancy and adjusting processor frequency in an out-of-band system according to Example 1 of the present invention. Such as image 3 As shown, in this method, firstly, the out-of-band system (for example: BIOS) obtains the processor occupancy rate, and when the obtained processor occupancy rate exceeds the preset processor occupancy rate range, the out-of-band system adjusts the processor frequency, and then Then get the processor usage again.

[0146] In Example 1, the processor occupancy rate may be acquired periodically, and the acquisition period may be determined according to the hardware processing capability of the out-of-band system, for example, 1-50 times per second. The processor occupancy rate can also be obtained when a preset condition is met, for example, the power consumptio...

[0188] Example 3. The out-of-band system adjusts the fan speed based on processor occupancy, processor frequency, ambient temperature, current fan speed, current temperature of a specific device, and temperature required for a specific device to work properly.

[0189] Table 1 is a list of parameters obtained in real time by the out-of-band system in Example 3.

[0191] Table 1

[0192] In Example 3, the BMC of the out-of-band system communicates with the BIOS to obtain the processor usage U_cpu in real time. In addition, the BMC of the out-of-band system acquires the processor frequency F_cpu, the environment temperature T_env, and the processor temperature T_cpu in real time. The BMC determines the first fan speed FS1 according to the processor occupancy rate U_cpu, processor frequency F_cpu, and ambient temperature T_env obtained in real time, so that the overall power consumption of the device P(server) is the lowest; according to the combination of the proces...

Abstract

The invention discloses a method and equipment for adjusting processor frequency, which are used for precisely acquiring the occupancy rate of a processor and adjusting the processor frequency. In the method provided by the embodiment of the invention, an out-band system reads the processor occupancy rate from the processor or determines the processor occupancy rate according to the specific parameter value returned from the processor after sending a command for reading a specific parameter value to the processor; the out-band system adjusts the processor frequency according to the obtained processor occupancy rate, wherein the out-band system comprises hardware operated by being independent from a user operation system in the equipment, and software operated on the hardware. After the method provided by the embodiment of the invention is adopted, the out-band system can directly obtain the processor frequency from the processor or determines the processor occupancy rate according to the specific parameter read from the processor, so the processor frequency is adjusted and the method and equipment have the advantage of high precision.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for adjusting processor frequency. Background technique [0002] With the rapid development of IT (Information Technology, information technology) technology, the use of equipment such as servers in various IT systems is becoming more and more popular. With the extensive use of servers and other equipment in IT systems, the problem of equipment power consumption and loss has become increasingly prominent. [0003] For equipment such as servers, the processor is one of the three basic components, which largely determines the processing and computing performance of the equipment. In order to improve the performance of the device, the number of transistors in the processor is continuously increased by multiples. While greatly improving the performance of the device, the power consumption and loss of the processor are also increasing. The power consumption of...
