Hello Everybody,
I want to ask following quesion:
sleep_avg in 2.6 kernel incremented every time process
go to sleep by the time in jiffies ,for which
task is in switch mode,this is good measure of task
being an intarctive
if i try to introduce the same variable in linux 2.4
kernel,with last_run,is the time when process calls
schedule,and if write the simple function,
just like in 2.6
fun(struct task_struct *p)
{
sleep_time=jiffies - p->last_run;
if(sleep_time)
sleep_avg+=sleep_time
}
and if sleep_time become MAX_SLEEP_AVG ,
i just print the log declaring it interactive,
but getting lot of error,like 'xtime' variable
is not of appropriate typr even though no
changes in 'xtime' variable
moreover the main problem is when to call 'fun'
I just called it ,every time before the
state of process is TASK_RUNNING,
Is it any problem in this approach?
or if totally wrong then plz tell
what exactly to do to just declare task as interactive
