(schedParms [relative_priority [scheduling_policy]])
The amount to decrease task priority. Similar to the Unix renice utility, a positive number will decrease the task priority. A negative number can be used to increase the task priority.
The OS scheduling policy to apply to the task, one of the following:
SCHED_FIFO The driver will execute until it blocks or is preempted by a higher priority process,
SCHED_RR The driver will be time-sliced with other processes at the same priority.
SCHED_OTHER An alternative scheduling algorithm that decays the priority if it consumes too much processor without blocking.
This command queries or sets the OS scheduling parameters for the driver process. The command is rarely needed, but may be helpful in tuning the real-time performance of the driver.
The correctness and effectiveness of this command is OS dependent.
