In this embodiment, the following two methods may be adopted to maintain the KVM of the BMC in the connected state:
first, a version of KVM is obtained that is not disconnected over time. Usually, the KVM of the BMC has a certain time limit, and the BMC is disconnected if not operated for a certain time.
Secondly, installing python at the client, executing a KVM-state.py script, and refreshing the KVM webpage version through a driver.refresh () statement, so as to maintain the connection state of the KVM.
S13: and retrieving and determining the video memory control of the server mainboard according to the acquired command.
In this embodiment, a video.exe test tool is adopted, and the test tool calls PCI information of a motherboard through functions GetDevicePCIInfo and a VideoEngineInfo interface to retrieve a video memory control of a server motherboard.
After the test environment is built, executing step S2: and setting an iteration coefficient and a cycle number recording parameter of a video memory test.
The iteration coefficient is used for describing the cycle number of the video memory compression test, and the cycle number recording parameter is used for recording the number of the video memory compression test which is executed. In this embodiment, the iteration coefficient is changed in the 2d-test. Inf file, and the value of the iteration coefficient is 1000000 generally. The 2d-test is a one-cycle stress test for memory. The number of cycles to perform the 2d-test is recorded with the loopcnt parameter.
According to the step S2, the video.EXE testing tool executes 2d-test by using a spawnl function, and refers to an iteration coefficient assignment count set in a 2d-test.INF file, namely, the 2d-test program needs to complete the pressurization of the count loops, and 1 is added to the loopcnt every time a loop is executed.
S3: and executing a cycle of video memory pressurization test.
Specifically, step S3 includes the following processes:
s31: and acquiring the display memory interface information of the mainboard according to the PCI information of the mainboard.
S32: and transmitting the pictures with various different resolutions to the BMC video memory according to the mainboard video memory interface information.
S33: and the BMC video memory performs graphic mask test on the picture to obtain a graphic mask test result.
The specific image mask testing process is as follows:
s331: and determining the first area and the second area according to the resolution of the picture.
The first area is an area for simply performing color rendering, and the second area is an area for needing reserved graph display.
S332: and rendering the first area.
S333: and determining the position of the graph in the second area according to the resolution of the picture.
S334: rendering the second region according to the determined position of the graph.
S34: and displaying the test result of the graphic mask in real time at the KVM terminal.
From the above steps S31 to S34, the pattern mask test performed by the method in the present embodiment includes the following steps:
a) Inquiring the PCI information of the mainboard through a function GetDevicePCIInfo and an interface VideoEngineInfo, and acquiring mainboard video memory interface information VGAPCIInfo;
b) After acquiring the interface information of the main board video memory, transmitting pictures with various resolutions such as broad1.Bmp, broad2.Bmp and the like in the test system into the video memory through spawnl function circulation;
c) The BMC video memory is tested by using two methods of pictures and simple time delay, namely: and carrying out graphic mask test on the picture through the BMC video memory so as to confirm the performance of the BMC video memory.
D) And through BMC and KVM technologies, the KVM is turned on, and the image information is displayed at the KVM terminal.
Thus, a pressure test cycle of the BMC video memory is completed, and the graphic information with different resolutions is displayed at the KVM terminal, so that the pressure test of the BMC video memory can be completed.
With continued reference to fig. 1, after the video memory compression test of one cycle is completed, step S4 is executed: and updating the cycle times by using the cycle time recording parameter.
S5: and judging whether the cycle number is smaller than the iteration coefficient.
And if the loop times are less than the iteration coefficient, returning to the step S3, and continuously executing the video memory pressurization test of the next loop.
If the loop times are not less than the iteration coefficient, that is, the loop times are equal to the iteration coefficient, step S6 is executed: and acquiring a test log.
That is, when loopcnt < count, the test result is returned after the pressure test is performed until the loop count has been completed, when the number of loops is less than the iteration coefficient, the test is not completed, and when the number of loops is not less than the iteration number, that is, when the number of loops is equal to the iteration number, the test is completed, step S6 is performed to obtain the test log.
S7: and determining a BMC video memory test result according to the test log.
Specifically, step S7 includes:
s71: and judging whether the KVM is interrupted or not in the BMC video memory test process according to the test log.
If there is a KVM interrupt in the BMC video memory test process, step S72 is executed: and judging that the test is not qualified.
If no KVM interrupt is detected during the BMC video memory test, step S73 is executed: and judging that the test is qualified.
From the above step S7, if 1000000 test cycles can be successfully completed in the test process, that is, when the video memory processes pictures or images with different resolutions, the video memory can be processed and switched smoothly, the video memory function is good, and PASS is tested. And if the intermediate test is stopped, the spawnl exits abnormally, the loopcnt completion number recorded in the test result is less than the set number, which indicates that the test is interrupted, and the FAIL is tested when the abnormal stop occurs.
