It could be wrong for the precision of runtime and deadline
when the precision is within microsecond level. For example:
Task runtime deadline period
P1 200us 500us 500us
This case need enbale HRTICK feature by the next command
PC#echo "HRTICK" > /sys/kernel/debug/sched_features
It could be wrong for the precision of runtime and deadline
when the precision is within microsecond level. For example:
Task runtime deadline period
P1 200us 500us 500us
This case need enbale HRTICK feature by the next command
PC#echo HRTICK /sys/kernel/debug/sched_features
PC#trace-cmd
