Problems solved by technology

For example, for a certain CPU, the CPU temperature has two thresholds, (T1, T2). When T2 is reached, the CPU is turned off; when T1 is reached, the CPU is turned on; (For example, with 8 cores, turn off several cores step by step). When the temperature drops to T2, you need to turn on the closed CPU (until it returns to 8 cores), which will cause frequent switching of the CPU, resulting in waste of system resources. Stability poses a hidden danger

Embodiment 1

[0054] Embodiment 1 (automatic adjustment)

[0055] figure 2 It is a flow chart of the method for controlling the hot plug operation of the CPU in the mobile terminal provided by Embodiment 1 of the present invention. figure 2 The methods shown include:

[0056] Step 201: monitoring the change of the switch state of the CPU in the previous time period;

[0057] Step 202: If the change of the switch state is greater than a certain value within a certain period of time, go to step 203;

[0058] In this step, the time period or the number of hotplug switches can be manually adjusted or selected. For example, Scenario 1: The time period is 5 minutes, and the number of hotplug switches is greater than 50 times; Scenario 2: The time period is 1 minute, and the number of hotplug switches is greater than 7 times; the sampling frequency is 1S or once according to the artificial setting. .

[0059]Specifically: start sampling, collect the hotplug status of each CPU according to t...

Embodiment 2

[0062] Embodiment 2 (manually adjusted, or selected according to the recommended value)

[0063] image 3 It is a flow chart of the method for controlling the hot plug operation of the CPU in the mobile terminal provided by Embodiment 2 of the present invention. image 3 The methods shown include:

[0064] Step 301: View the change of the switch status of the monitoring CPU in the previous period; and read the corresponding temperature value.

[0065] Step 302: If the change of the switch state is greater than a certain value within a certain period of time, an alarm is given, and then step 303 is reached;

[0066] This is due to manual adjustment. If the user sees the frequent status of hotplug, he can choose several configuration items recommended by the system. For example, choose 1: lower the temperature range of the lower limit of the CPU with the most frequent hotplug by 2 degrees; choose 2: lower the temperature range of the first two CPUs with more frequent hotplugs...

Abstract

Provided are a method and apparatus for controlling a hot plug operation of a CPU in a mobile terminal. The method includes: adjusting (101) at least one temperature threshold of the CPU when detecting that a number of hot plug operations of the CPU within a preset period is greater than a preset threshold, where the temperature threshold is used for controlling the hot plug operations of the CPU; and controlling (102) the hot plug operation of the CPU by use of the adjusted temperature threshold.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for controlling hot plug operation of a CPU in a mobile terminal. Background technique [0002] Now the number of cores in mobile phones is increasing, and the heat generation is also very high. The temperature values ​​of each CPU in the chip are detected by various temperature sensors. For example, for a certain CPU, the CPU temperature has two thresholds, (T1, T2). When T2 is reached, the CPU is turned off; when T1 is reached, the CPU is turned on; (For example, with 8 cores, turn off several cores step by step). When the temperature drops to T2, you need to turn on the closed CPU (until it returns to 8 cores), which will cause frequent switching of the CPU, resulting in waste of system resources. Stability poses a risk. Contents of the invention [0003] The technical problem to be solved by the method and device for controlling the hot plug operation of th...
