[0058] In order to make the above-mentioned objects, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0059] The ARM server supports dual CPU by default, but some users choose single CPU for cost saving. In the case of using single CPU, it is found that the GPU cannot be tested under pressure, which will affect the normal operation of the actual business. After comparison and analysis, it is found that the GPU enters the throttle mode, which causes the GPU to be unable to be tested under pressure. Further measurement of EE waveform and actual test shows that the throttle control signal B30 signal state value of the PCI link is not correct. When the dual CPU is used, the signal is pulled high, and it is verified that the GPU can be tested under pressure in the case of dual CPU. When the single CPU is used, the GPU cannot be tested under pressure, which is because the signal is at low level.

[0060] Therefore, the application adopts a complex programmable logic device (CPLD) to judge the in-place situation of the first central processor and the second central processor. When the first central processor or the second central processor is turned on, the B30 state value of the PCI link connected with the first central processor or the second central processor is adjusted to high level, i.e. the throttle function of the first graphics processor or the second graphics processor is closed, so that even if a single CPU is used, the first graphics processor or the second graphics processor can be tested under pressure.

[0061] Reference Figure 1 , a step flow chart of a graphics processor throttle function adjustment method provided in an embodiment of the application is shown, which can specifically include the following steps:

[0062] Step 101, when the basic input and output system is started, the complex programmable logic device receives the first in-place signal sent by the first central processor or the second in-place signal sent by the second central processor;

[0063] The method of the embodiment of the application can be applied to an ARM server, and the ARM server can include at least one central processor, at least one graphics processor and a complex programmable logic device. The central processor can be connected with the graphics processor through a PCI link. In the case that the central processor is turned off, the graphics processor is in the off state. In the case that only one central processor is started, the graphics processor can be in the throttle mode, so that the graphics processor cannot be tested under pressure.

[0064] In order to make the graphics processor also be able to be tested under pressure in the case that only one central processor is started, the throttle function of the graphics processor in the case that one central processor is started can be closed, so that the graphics processor can be supported to be tested under pressure.

[0065] Specifically, by default, the ARM server can include two central processors, i.e., a first central processor and a second central processor, the first central processor can be connected with the first graphics processor through a first PCI link, and the second central processor can be connected with the second graphics processor through a second PCI link.

[0066] In the case of starting the basic input output system, the central processor is also started to interpret instructions and process data, at this time, the central processor sends a present signal to the complex programmable logic device so that the complex programmable logic device knows the present information of the central processor. Specifically, when only one central processor is present, the complex programmable logic device can only receive the first present signal sent by the first central processor or the second present signal sent by the second central processor.

[0067] Step 102, the complex programmable logic device determines whether the first central processor is started according to the first present signal, or determines whether the second central processor is started according to the second present signal;

[0068] The present signal sent by the central processor to the complex programmable logic device can include two cases, the first case is that the central processor is in a starting state, and the second case is that the central processor is about to be closed, so the complex programmable logic device can determine the present state of the first central processor or the second central processor according to the present signal after receiving the present signal. Specifically, the first central processor can be determined to be in a starting state according to the first present signal, or the second central processor can be determined to be in a starting state according to the second present signal.

[0069] Step 103, if it is determined that the first central processor is in a starting state, the complex programmable logic device adjusts the throttling function of the first graphics processor connected with the first central processor to a closed state, or if it is determined that the second central processor is in a starting state, the complex programmable logic device adjusts the throttling function of the second graphics processor connected with the second central processor to a closed state.

[0070] If the meaning represented by the first present signal is starting, the complex programmable logic device can determine that the first central processor is in a starting state, at this time, the throttling function of the first graphics processor connected with the first central processor can be adjusted to a closed state, so that the first graphics processor can perform a stress test; if the meaning represented by the second present signal is starting, the complex programmable logic device can determine that the second central processor is in a starting state, at this time, the throttling function of the second graphics processor connected with the second central processor can be adjusted to a closed state, so that the second graphics processor can perform a stress test.

[0071] The adjustment method of the throttling function of the graphic processor provided by the embodiment of the application can support the graphic processor to perform stress testing even if only one central processor is in place.

[0072] Referring to Figure 2 The step flow chart of another adjustment method of the throttling function of the graphic processor provided by the embodiment of the application is shown, and the method can specifically include the following steps:

[0073] In step 201, when the basic input and output system is started, the complex programmable logic device receives a first in-place signal sent by a first central processor or a second in-place signal sent by a second central processor.

[0074] The method of the embodiment of the application can be applied to an ARM server, and the ARM server can include at least one central processor, at least one graphic processor and a complex programmable logic device.

[0075] In order to enable the graphic processor to perform stress testing even if only one central processor is started, the throttling function of the graphic processor in the case of one central processor being started can be closed, so that the graphic processor can perform stress testing.

[0076] Specifically, by default, the ARM server can include two central processors, i.e., a first central processor and a second central processor.

[0077] In the case of the basic input output system starting, the central processor also starts to interpret instructions and process data, at this time, the central processor sends the on signal to the complex programmable logic device, so that the complex programmable logic device knows the on information of the central processor. Specifically, when only one central processor is on, the complex programmable logic device can only receive the first on signal sent by the first central processor or the second on signal sent by the second central processor.

[0078] In step 202, the complex programmable logic device judges whether the first central processor starts according to the first on signal, or judges whether the second central processor starts according to the second on signal.

[0079] The on signal sent by the central processor to the complex programmable logic device can include two cases, the first case is that the central processor is in the starting state, and the second case is that the central processor is about to be closed, so the complex programmable logic device can judge the on state of the first central processor or the second central processor according to the on signal after receiving the on signal. Specifically, the first central processor can be judged to start according to the first on signal, or the second central processor can be judged to start according to the second on signal.

[0080] In an embodiment of the present application, the complex programmable logic device judges whether the first central processor starts according to the first on signal, or judges whether the second central processor starts according to the second on signal, including:

[0081] In step S11, if the first on signal is in a high level state, it is determined that the first central processor is in a starting state, or if the second on signal is in a high level state, it is determined that the second central processor is in a starting state.

[0082] The on signal can include two cases, the first case is that the on signal is in a high level state, indicating that the central processor is in a starting state, and the second case is that the on signal is in a low level state, indicating that the central processor is about to be closed, so the complex programmable logic device can judge the on state of the first central processor or the second central processor according to the on signal after receiving the on signal. Specifically, if the first on signal is in a high level state, it can be determined that the first central processor is in a starting state; if the second on signal is in a high level state, it can be determined that the second central processor is in a starting state.

[0083] Step 203, if it is determined that the first central processor is in the start state, the complex programmable logic device adjusts the throttle control signal state value of the first PCI link of the first central processor to high level, or if it is determined that the second central processor is in the start state, the complex programmable logic device adjusts the throttle control signal state value of the second PCI link of the second central processor to high level.

[0084] The central processor is connected with the graphic processor through the PCI link, and the opening or closing of the throttle function of the graphic processor is controlled by the throttle control signal of the PCI link. The complex programmable logic device can close the throttle function of the graphic processor by adjusting the throttle control signal of the PCI link to high level, and can open the throttle function of the graphic processor by adjusting the throttle control signal of the PCI link to low level.

[0085] Specifically, if the first in-place signal is in a high level state, the complex programmable logic device can determine that the first central processor is in the start state, at this time, the throttle control signal state value of the first PCI link of the first central processor can be adjusted to high level, so that the first graphic processor can perform the stress test; if the second in-place signal is in a high level state, the complex programmable logic device can determine that the second central processor is in the start state, at this time, the throttle control signal state value of the second PCI link of the second central processor can be adjusted to high level, so that the second graphic processor can perform the stress test.

[0086] In an embodiment of the present application, the method further comprises:

[0087] S21, if it is determined that the first central processor or the second central processor is in the start state, the complex programmable logic device adjusts the throttle function of the third graphic processor connected with the first central processor and the second central processor to the closed state.

[0088] One graphic processor can be connected with one central processor alone, or can be connected with two central processors, for example, the third graphic processor can be connected with the first central processor and the second central processor.

[0089] Thus, if the meaning represented by the first in-place signal is start, the complex programmable logic device can determine that the first central processing unit is in a start state, at which time, the throttling function of the third graphics processing unit connected with the first central processing unit and the second central processing unit can be adjusted to a closed state, so that the third graphics processing unit can perform a stress test; if the meaning represented by the second in-place signal is start, the complex programmable logic device can determine that the second central processing unit is in a start state, at which time, the throttling function of the third graphics processing unit connected with the first central processing unit and the second central processing unit can be adjusted to a closed state, so that the third graphics processing unit can perform a stress test.

[0090] In an embodiment of the present application, the method further comprises:

[0091] S31, the complex programmable logic device receives the first high temperature alarm signal sent by the first central processing unit or the second high temperature alarm signal sent by the second central processing unit;

[0092] In the process of running the central processing unit, the central processing unit can send a high temperature alarm signal to the complex programmable logic device, and the high temperature alarm signal can include two cases of low level and high level, when the high temperature alarm signal is low level, it indicates that the temperature of the central processing unit does not reach the preset threshold, and the central processing unit can continue to run normally; when the high temperature alarm signal is high level, it indicates that the temperature of the central processing unit is too high, and the complex programmable logic device can control the central processing unit to execute the shutdown code logic program, so as to avoid physical burnout of the CPU.

[0093] Specifically, the complex programmable logic device can receive the first high temperature alarm signal sent by the first central processing unit, or the second high temperature alarm signal sent by the second central processing unit, and the complex programmable logic device can judge the state of the high temperature alarm signal after receiving the high temperature alarm signal, and control the central processing unit to execute the corresponding code logic program according to the state of the high temperature alarm signal.

[0094] S32, if the first high temperature alarm signal is high level, the first central processing unit is closed, or if the second high temperature alarm signal is high level, the second central processing unit is closed.

[0095] After the complex programmable logic device receives the first high temperature alarm signal, if it is determined that the first high temperature alarm signal is high level, it indicates that the temperature of the first central processing unit is too high, and the first central processing unit can be closed to avoid being burned out; after the complex programmable logic device receives the second high temperature alarm signal, if it is determined that the second high temperature alarm signal is high level, it indicates that the temperature of the second central processing unit is too high, and the second central processing unit can be closed to avoid being burned out.

[0096] In an embodiment of the present application, the method further comprises:

[0097] S41, when the basic input output system is started, the complex programmable logic device receives the first in-place signal sent by the first central processing unit and the second in-place signal sent by the second central processing unit;

[0098] In the case that both CPUs of the ARM server are in the starting state, if the graphic processors connected with the two CPUs are both in the throttling state, the graphic processors cannot perform the stress test at this time, so in the case that both CPUs of the ARM server are in the starting state, the stress test of the graphic processors can be supported by closing the throttling functions of the two graphic processors.

[0099] Specifically, in the case that the basic input output system is started, the first central processing unit and the second central processing unit can send in-place signals to the complex programmable logic device, so that the complex programmable logic device can learn the in-place information of the central processing unit according to the received in-place signals.

[0100] S42, the complex programmable logic device determines whether the first central processing unit is started according to the first in-place signal, and determines whether the second central processing unit is started according to the second in-place signal;

[0101] After receiving the in-place signals, the complex programmable logic device can determine the in-place state of the first central processing unit or the second central processing unit according to the in-place signals, specifically, it can determine whether the first central processing unit is started according to the first in-place signal, and determine whether the second central processing unit is started according to the second in-place signal.

[0102] S43, if it is determined that the first central processing unit is in the starting state, the complex programmable logic device adjusts the throttling function of the first graphic processor connected with the first central processing unit to the closed state, and if it is determined that the second central processing unit is in the starting state, adjusts the throttling function of the second graphic processor connected with the second central processing unit to the closed state.

[0103] If the first in-place signal is in a high level state, the complex programmable logic device can determine that the first central processor is in a start state, at this time, the throttling function of the first graphics processor connected with the first central processor can be adjusted to a closed state, so that the first graphics processor can perform a stress test; if the second in-place signal is in a high level state, the complex programmable logic device can determine that the second central processor is in a start state, at this time, the throttling function of the second graphics processor connected with the second central processor can be adjusted to a closed state, so that the second graphics processor can perform a stress test. Thus, in the case that both CPUs in the ARM server are started, the graphics processor can also support stress testing.

[0104] In an embodiment of the present application, the method further comprises:

[0105] S51, the complex programmable logic device receives the first high temperature alarm signal sent by the first central processor and the second high temperature alarm signal sent by the second central processor;

[0106] In the case that both CPUs in the ARM server are started, the complex programmable logic device can receive the first high temperature alarm signal sent by the first central processor and the second high temperature alarm signal sent by the second central processor, and after receiving the high temperature alarm signal, the complex programmable logic device can judge the state of the high temperature alarm signal and control the central processor to execute the corresponding code logic program according to the state of the high temperature alarm signal.

[0107] S52, if the first high temperature alarm signal is in a high level state, the first central processor is closed, and if the second high temperature alarm signal is in a high level state, the second central processor is closed;

[0108] After the complex programmable logic device receives the first high temperature alarm signal, if it is determined that the first high temperature alarm signal is in a high level state, it means that the temperature of the first central processor is too high, so the first central processor can be closed to avoid being burned out. After the complex programmable logic device receives the second high temperature alarm signal, if it is determined that the second high temperature alarm signal is in a high level state, it means that the temperature of the second central processor is too high, so the second central processor can be closed to avoid being burned out. Thus, in the case that the temperature of both CPUs in the ARM server is too high, both CPUs can be closed to avoid burning out the central processor.

[0109] S53, if the first high temperature alarm signal is in a high level state and the second high temperature alarm signal is in a low level state, the first central processor is closed, or if the second high temperature alarm signal is in a high level state and the first high temperature alarm signal is in a low level state, the second central processor is closed.

[0110] After receiving the high temperature alarm signals sent by the two central processors, if the temperature of one central processor is too high and the temperature of the other central processor is within the normal temperature range, only the central processor with the too high temperature can be turned off, and the central processor with the temperature within the normal temperature range can be normally operated.

[0111] Specifically, if the first high temperature alarm signal is in the high level state and the second high temperature alarm signal is in the low level state, only the first central processor can be turned off; if the second high temperature alarm signal is in the high level state and the first high temperature alarm signal is in the low level state, only the second central processor can be turned off. Thus, the central processor with the too high temperature can be prevented from being burned out, the ARM server can continue to operate by using the central processor with the temperature within the normal temperature range, the user can be prevented from delaying the processing of the business, and the graphics processor connected to the central processor with the temperature within the normal temperature range can be subjected to the pressure test.

[0112] Referring to Figure 3 , a flowchart for adjusting the throttle function of the graphics processor is shown. The specific process is as follows:

[0113] 1. In the case of starting the basic input and output system, the complex programmable logic device adjusts the throttle control signal of the first PCI link of the first central processor and / or the throttle control signal of the second PCI link of the second central processor according to the first in-place signal sent by the first central processor and / or the second in-place signal sent by the second central processor, to determine the starting state of the first central processor and / or the second central processor;
