[0058] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0059] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0060] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0061] In the related art, the host is used to adjust the operating parameters of the GPU, and the adjustment process is as follows: Figure 1 As shown, the parameter adjustment tool of the application layer running in the host initiates a parameter adjustment request to the host through the ioctl (I / O Control) system interface (an interface used for communication between device drivers and user space programs in the operating system). After receiving the parameter adjustment request, the host's kernel driver constructs an IPC message and initiates IPC (Inner-Process Communication) communication to the GPU. The System Management Unit (SMU) on the GPU adjusts the operating parameters of the components and modules in the GPU accordingly based on the operating parameters in the received IPC message. However, Figure 1 The parameter adjustment process of the method in the above method needs to be implemented by the kernel driver of the host. The parameter adjustment program code runs in the kernel driver, which makes the entire parameter adjustment process limited by the kernel driver. The exception of the kernel driver code will cause the entire device to freeze or hang, and the parameter adjustment cannot be performed. In addition, the code runs in the kernel driver, which is very inconvenient and costly to debug.

[0062] To solve the above problems, the embodiments of the present disclosure provide a parameter adjustment method, device and system, which minimize the dependence of the entire parameter adjustment process on the kernel driver of the host, achieve high debuggability of the parameter adjustment program code, low development and maintenance costs, and improve the development speed of the program code.

[0063] The embodiment of the present disclosure provides an operation parameter adjustment system, which includes parameter adjustment devices respectively applied to a host 100 and each device 200 (the device 200 includes a target device for which operation parameters need to be adjusted). Figure 2As shown, the parameter adjustment device in the host 100 includes a parameter adjustment module 11. The parameter adjustment device in the device 200 includes a shared memory 21, a target interrupt register 22 and a system management module 23.

[0064] The parameter adjustment module 11 is used to create a parameter adjustment message according to the parameter adjustment operation for the target device when a parameter adjustment operation for the target device is detected, and write the parameter adjustment message into the shared memory 21 in the target device; and then write a set value into the target interrupt register 22 of the target device, so that the target device sends an interrupt signal to the system management module 23 when the target device detects that the target interrupt register 22 is written with the set value, and the parameter adjustment message includes at least one operating parameter for the target device. The parameter adjustment operation includes an input operation and / or an adjustment operation for the operating parameter.

[0065] The system management module 23 is used to read the parameter adjustment message from the shared memory 21 when an interrupt signal is received; and to adjust the parameters for the target device based on at least one parameter in the parameter adjustment message.

[0066] In this embodiment, the parameter adjustment module 11 can be set as a parameter adjustment tool, which runs in the host 100 in the form of a software program, is in the application layer, and can provide users with an interface that can input and / or adjust operating parameters and select target devices. The parameter adjustment tool generates a parameter adjustment operation for a certain target device based on the input operation and / or adjustment operation detected for the interface. Since the parameter adjustment tool runs in the host 100 instead of running in the kernel driver of the host 100, the developer can adjust the code of the parameter adjustment tool as needed, and the debugging of the parameter adjustment tool is very convenient, which reduces the development and maintenance costs of the parameter adjustment tool, and further reduces the development and maintenance costs of host subordinate devices such as GPUs. Moreover, since the parameter adjustment tool runs in the host 100 but not in the kernel driver of the host 100, the parameter adjustment message is directly written to the shared memory during the parameter adjustment process without passing through the kernel driver, so that the entire parameter adjustment process is no longer limited to the kernel driver, ensuring that the parameter adjustment is minimized by the kernel driver of the host.

[0067] In this embodiment, after acquiring the parameter adjustment message, the system management module 23 parses the parameter adjustment message according to the preset data structure definition of the parameter adjustment message to obtain specific operating parameters, and then initiates a parameter adjustment action on the graphics card of the target device based on the specific parameter adjustment conditions targeted by the operating parameters, so that the graphics card can adjust the corresponding modules and devices in the target device based on the operating parameters in the parameter adjustment message. Among them, the data structure definition of the parameter adjustment message can be pre-set, indicating the specific meanings of the parameters at different positions in the entire parameter adjustment message, and / or the specific meanings indicated by the parameters with different identifiers, so as to simplify the parsing process of the parameter adjustment message.

[0068] In this embodiment, since the parameter adjustment module 11 needs to write the parameter adjustment message into the shared memory of the target device, the parameter adjustment module 11 needs to obtain the access capability of the shared memory of each device 200 in advance. The following describes the implementation method of the device to achieve this capability.

[0069] like Figure 3 As shown, the parameter adjustment device in the host 100 also includes a PCIE driver (PCI Express driver, also known as PCIe driver) 12. The device 200 is a PCIE device, that is, the device 200 and the host 100 perform data transmission based on the PCIe (Peripheral Component Interconnect-Epress, peripheral component high-speed interconnect standard) protocol. Then the PCIE driver 12 is used to obtain the address information of the storage space of each PCIE device connected to the host 100 before the parameter adjustment module 11 is initialized for parameter adjustment; according to the address information of the storage space of each PCIE device, a device file (File Handle) of each PCIE device is created. Among them, the PCIE device includes at least one GPU, and the storage space of each GPU includes at least one BAR (Base Address Register) space, and the address information of the GPU can be the starting address and address space length of the BAR space. The target device is one or more of the at least one GPU, and the shared memory 21 is located in a BAR space of the GPU as the target device.

[0070] After the PCIE driver 12 creates the device files of each PCIE device, the parameter adjustment module 11 can obtain the device files of each PCIE device connected to the host 100; perform memory mapping (memory map, mmap) according to the file handle corresponding to the device file of each PCIE device, and map the storage space of each PCIE device to the corresponding virtual address space. Taking the PICE device as a GPU as an example, after the PCIE driver 12 creates the corresponding device file based on the address information of the BAR space of each GPU, the parameter adjustment tool (that is, the parameter adjustment module 11) can open the device file of each GPU during initialization, and then map each BAR space of each GPU to the process space of the parameter adjustment tool based on the mmap method, thereby obtaining the ability to access the BAR space of each GPU.

[0071] In some embodiments, when the PCIE driver 12 detects that the PCIE device connected to the host 100 has changed, the device file can be updated according to the change, such as deleting the device file of the non-existent PCIE device, creating the device file of the newly added PCIE device, and updating the device file of the PCIE device according to the change of the address information of the storage space of the PCIE device. In addition, after determining that the device file update is completed, the PCIE driver 12 can notify the parameter adjustment module 11 of the update status, so that the parameter adjustment module 11 can update the memory mapping of the device file based on the update status of the device file to ensure that the parameter adjustment is accurate.

[0072] In some embodiments, when the device 200 is a GPU, the target interrupt register 22 can be set in a BAR space of the device 200. The shared memory 21 and the target interrupt register in the same device 200 can be set in the same BAR space or in different BAR spaces. The present disclosure does not impose any restrictions on this.

[0073] In this embodiment, in order to ensure smooth parameter adjustment, after writing the parameter adjustment message into the shared memory of the target device, the parameter adjustment module 11 also needs to notify the system management module 23 of the target device that the parameter adjustment needs to be performed. Figure 3 As shown, the parameter adjustment device in the device 200 also includes a monitoring module 24. After writing the parameter adjustment message into the shared memory of the target device, the parameter adjustment module 11 can write a set value into the target interrupt register 22 of the target device. When the monitoring module 24 in the target device detects that the target interrupt register 22 is written with the set value, it sends an interrupt signal to the system management module 23 of the target device. In this way, the system management module 23 can be simply, directly and accurately notified to adjust the operating parameters of the target device.

[0074] In this embodiment, the monitoring module 24 may be implemented by hardware and / or software in each device 200, and the present disclosure does not limit this.

[0075] In some embodiments, the parameter adjustment message may be an IPC message. That is, the parameter adjustment message may be a message based on IPC communication. The operating parameters carried in the parameter adjustment message correspond to the target device. Different target devices may have different types of operating parameters, and the present disclosure does not limit this.

[0076] For example, if Figure 4 As shown, it is assumed that the user needs to adjust the frequency of a GPU from the original 1.5GHz to 1.1GHz. The parameter adjustment tool (i.e., the parameter adjustment module 11) can create an IPC message based on the latest frequency "1.1GHz" input by the user and the selected target GPU (i.e., the target device), and send the IPC message carrying at least the operating parameter "1.1GHz" to the shared memory 21 of each target GPU, and then write the set value to the target interrupt register 22 of each target GPU. For each GPU, the monitoring module 24 thereon will continuously monitor the target interrupt register 22, and when it detects that the target interrupt register 22 is written with the set value, it will send an interrupt signal to the system management module 23 of the device. After receiving the interrupt signal, the system management module 23 will read the IPC message from the shared memory 21, and then adjust its own frequency from the original 1.5GHz to 1.1GHz indicated by the IPC message.

[0077] like Figure 5 As shown, the embodiment of the present disclosure further provides a parameter adjustment method, which is applied to the above host 100, and the method includes:

[0078] Step S401, when a parameter adjustment operation for a target device is detected, creating a parameter adjustment message according to the parameter adjustment operation, wherein the parameter adjustment message includes at least one operating parameter for the target device, and the parameter adjustment operation includes an input operation and / or an adjustment operation for the operating parameter;

[0079] Step S401, writing the parameter adjustment message into the shared memory in the target device;

[0080] Step S401, write a set value into the target interrupt register of the target device, so that when the target device detects that the set value is written into the target interrupt register, it sends an interrupt signal to the system management module of the target device, so that the system management module obtains the parameter adjustment message from the shared memory in response to the interrupt signal, and adjusts the parameters for the target device based on the parameter adjustment message.

[0081] In a possible implementation, the method may further include:

[0082] Obtain device files of each PCIE device connected to the host; perform memory mapping according to the file handle corresponding to the device file of each PCIE device, and map the storage space of each PCIE device to the corresponding virtual address space;

[0083] The PCIE device includes at least one GPU, the storage space of each GPU includes at least one BAR space, the target device is one or more of the at least one GPU, and the shared memory is located in a BAR space of the GPU serving as the target device.

[0084] In a possible implementation, the method may further include: controlling a PCIE driver of the host to obtain address information of a storage space of each PCIE device connected to the host; and creating a device file of each PCIE device according to the address information of the storage space of each PCIE device.

[0085] In one possible implementation, the parameter adjustment message includes an IPC message.

[0086] like Figure 6 As shown, the embodiment of the present disclosure further provides a parameter adjustment method, which is applied to the above-mentioned device 200, and the method includes:

[0087] Step S501, when an interrupt signal is received, reading a parameter adjustment message from a shared memory of the device;

[0089] Among them, the parameter adjustment message is written into the shared memory by the host controlling the device.

[0090] In a possible implementation, the device is one or more PCIE devices connected to the host;

[0091] The PCIE device includes at least one GPU, and the storage space of each GPU includes at least one BAR space. When the device is one or more GPUs in the at least one GPU, the shared memory is located in a BAR space of the GPU.

[0092] In a possible implementation, the method may further include:

[0093] A target interrupt register in the device is monitored, and when it is detected that a set value is written into the target interrupt register, an interrupt signal is sent to a system management module of the device.

[0094] In one possible implementation, the parameter adjustment message includes an IPC message.
