Before mass production, the ArmSoM team will conduct several rounds of professional functional testing and performance stress testing on the products to ensure product quality and stability.
-
Excellent products require multiple comprehensive functional and performance stress tests to withstand market validation.
-
Hardware environment: ArmSoM-W3 RK3588 development board
-
Software version: OS: ArmSoM-W3 Debian11
-
rk-msch-probe-for-user is an official tool used to monitor and collect statistics on system DDR load and bandwidth usage. It can display real-time DDR load and bandwidth information.
-
Use the rk-msch-probe-for-use tool to monitor and collect statistics on system DDR load and bandwidth usage.
-
Test principle: Run the official Rockchip DDR bandwidth test tool to monitor and collect statistics on system DDR load and bandwidth usage.

The rk-msch-probe-for-user tool needs to run in frequency lock mode. Set DDR frequency lock to the highest frequency 2112MHz
//Switch to user space root@linaro-alip:/# echo userspace > sys/class/devfreq/dmc/governor //Get supported frequency information root@linaro-alip:/# cat sys/class/devfreq/dmc/available_frequencies 528000000 1068000000 1560000000 2112000000 //Set DDR frequency lock to the highest frequency 2112MHz root@linaro-alip:/# echo 2112000000 > sys/class/devfreq/dmc/userspace/set_freq

Run applications that need to monitor ddr information on the device, and monitor ddr bandwidth usage in real time.
According to the test results above: During the 1000ms monitoring time, the average bandwidth of all channels is 1045.22MB/s, and the load is 3.09%.
ALL: Total bandwidth statistics for all channels
CHx: Bandwidth statistics for DDR channel x
LOAD: Bandwidth and load for this channel across all DDR banks
RD: Read bandwidth and percentage across all DDR banks
WR: Write bandwidth and percentage across all DDR banks
