AM5728: Scheduling policy and priority of processes

Vishal Maheshwari

Part Number: AM5728

Hi,

We are using custom board based on AM5728. We are observing that the response of the LCD and some drivers on the software are slow. We are using SDK6.03 currently.

We would like to know :

1. What is the default scheduling policy that is used in the Kernel scheduler in TI SDK 6.03?

2. how can we create processes with a higher priority other than default priority ?

Hello Vishal,

Please see the following man page: https://man7.org/linux/man-pages/man7/sched.7.html, it should answer both your questions.
This can be also proved in the code here https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/kernel/kthread.c?h=ti-linux-4.19.y#n340.Please look into this in the open source community, there are many threads like the following:

Nice article: https://www.tecmint.com/set-linux-process-priority-using-nice-and-renice-commands/
And another one from this Forum: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1305149/tda4vh-q1-set-task-priority-for-network-stack-daemon
