say use kthread_create func ,my question is :how can i make this thread to run on a cpu and never get switched or scheduled , there is a while(1).....structure in that thread i need it to do work
That's almost certainly a result of a poor design. What problem were you trying to solve by wrapping a 'while(1)' around in-kernel code?
comes with errors like "NMI watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [test thread :1881]",i understand there is a watchdog but is there anyway i can feed the dog myself and let my thread have cpu as much as i want ?
There are ways. But you probably should figure out how to fix your code so feeding the watchdog isn't needed....
