Hi, everyone

How can I prevent other processes than my specific application from being scheduled?

I thougt that when my program being started, it would invokes the kernel to do "local_irq_disable()" and when it ended, it would call "local_irq_enable()" in order that scheduler not working when my specific program runs.

But i seems do not work as I likes.

Please give me some hints what i should do...

Thanks in advance.

Sounds like you need to do (near) real time scheduling by using SCHED_FIFO scheduling class. CMIIW .... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
