Hi, We are using the IMX8 mini as the mainboard, we found that when system is runing, there would be a 300ms stall which happend frequently.
To find the reason, we made a test tool just using two threads, which invoke "gettimeofday" to get the time cyclically.
We found that at one point, there was a delay of more than 300ms between the two prints.
We used the perf sched record ./pthread_test command to obtain the on-site scheduling information, and found that there was indeed a delay of 300ms.
I am appreciated if someone could help me out.
