Testing the Video Stream Cloud Phone Density

1. Log in to the BMC over SSH.

   1	ssh {BMC_user_name}@{BMC_IP_address}

2. Set the fan speed adjustment mode to manual.

   1	ipmcset -d fanmode -v 1 0

   The command output is as follows:

   1 2 3

   Set fan mode successfully. Current Mode: manual Time out : 100000000 seconds

3. Set the fan speed percentage to 100%.

   1	ipmcset -d fanlevel -v 100

   The command output is as follows:

   1 2 3

   Set fan level successfully. Current Mode: manual, timeout 100000000 seconds. Global Manual Fan Level: 100%

4. Query the fan status.

   1	ipmcget -d faninfo

   The command output is as follows:

   1 2 3

   Current Mode: manual, timeout 100000000 seconds. Manual fan level: Fan1: 100, Fan2: 100, Fan3: 100, Fan4: 100

1. Query the GPU process ID.

   1	ps -ef |grep gfx

   The command output is as follows:

   1 2	root 1703 2 1 Aug31 ? 07:31:36 [gfx_0.0.0] root 1739 2 1 Aug31 ? 09:13:08 [gfx_0.0.0]

2. Bind the first GPU process to an idle core.

   1	taskset -pc 32-33 1703

   The command output is as follows:

   1 2	pid 1703's current affinity list: 0-127 pid 1703's new affinity list: 32,33

3. Bind the second GPU process to an idle core.

   1	taskset -pc 64-65 1739

   The command output is as follows:

   1 2	pid 1739's current affinity list: 0-127 pid 1739's new affinity list: 64,65

   If four GPU driver processes are displayed, bind the first two driver processes to cores 32 to 33 and the last two driver processes to cores 64 to 65.

If the 7260 processor + W6600 density test in Table 1 is performed, ensure that Modifying the W6600 Density Test Configuration has been performed.

To test the high-quality image of the Genshin Impact login page, you need to log in to the game account and set the parameters. To perform a multi-channel test, log in to the game for one channel, set the image quality, and log out. Refer to Creating a Base Data Volume and create a base data volume to ensure that the image quality of the containers started later are consistent.

1. Start the cloud phone.

   1	./cfct_video start 1 60

2. Open the Genshin Impact game.

   1	./cfct_video start_ygame 1 60

3. Screen capture.

   1	./cfct_video screencap 1 60

After screen capture is complete, download the screenshots to the local host. If all screenshots are game screens of Genshin Impact, as shown in the following figure, the app is successfully started.

1. Decompress the pressure test tool VideoClientEmulator.tar.gz on the local host or another server.

   1 2	tar -xvpf VideoClientEmulator.tar.gz cd VideoClientEmulator

2. Modify the core binding mode in the config file of the pressure test tool. If the test is performed on the local host, allocate and bind the tool to idle cores. The following is a configuration example:

   # CPU allocated to the pressure test tool
   CPU_FOR_CLIENT=("32" "96" "33" "97")
   CPU_FOR_SERVER="64"
   CPU_FOR_CMD="65"

3. Run the following command to connect to the server.
   If the test is performed on the local host, the IP address can be 127.0.0.1. An example command is as follows. The parameters that follow ./test.sh connect are the server IP address, start port number, and end port number, respectively.

   1	./test.sh connect 127.0.0.1 8001 8060

   Check whether the number of clients displayed in the output is correct. For example:

   1 2	[INFO] checking current client num ... [INFO] current client process num: =60

4. Run the following command to display and collect frame rate data.
   The following command is an example. The parameters that follow ./test.sh start are the server IP address, start port number, end port number, and collection time, respectively.

   1	./test.sh start 127.0.0.1 8001 8060 900

   After the 15-minute countdown, an analysis report of the frame rate data is generated, as shown in the following figure. A CSV file that records single-channel data is generated in the test directory.

   

1. Obtain the native_perf_tools_20230830.tar.gz package by referring to Video Stream Engine, decompress it, and go to the native_perf_tools folder.
2. The native perf tools depend on the nmon tool. If the nmon tool is not installed, run apt to install it.

   1	apt install nmon

3. Run the following commands in sequence to collect data for 15 minutes. {prefix_number} is the prefix of the folder for storing collected data.

   1 2	source env.sh ./native_get_perf_data.sh all {prefix_number}

   

1. log folder in the native_perf_tools folder on the server, which contains performance data of the server, such as performance data of CPUs, GPUs, and encoding cards.
2. The client.log file in the /sdcard/log directory on the mobile phone client is the client log file, including information about the decoding frame rate and network lag.
3. Place the preceding files and folders in the same path, for example, D:\tmp.
   Download ExtractingData_20230310.tar.gz and decompress it. Go to the ExtractingData folder and run the following command:

   python parse.py D:\tmp

   An output folder is generated in D:\tmp, which contains tables and images.
