P_set_policy_disable.html [plain text]
<strong>Function</strong> - Disables a scheduling policy for a processor set.
[in processor-set-control port] The control port for the processor set for which a scheduling policy is to be disabled.
[in scalar] Policy to be disabled. The values currently defined are POLICY_TIMESHARE and POLICY_FIXEDPRI.
[in scalar] If true, causes the scheduling policy for all threads currently running with policy to POLICY_TIMESHARE.
function restricts the set of scheduling policies allowed for
<var>processor_set</var>. The set of scheduling policies allowed for a
processor set is the set of policies allowed to be set for threads
assigned to that processor set. The current set of permitted policies
can be obtained from <strong>processor_set_info</strong>. Timesharing may
not be forbidden for any processor set. This is a compromise to reduce
the complexity of the assign operation; any thread whose
<var>policy</var> is forbidden by its target processor set has its
<var>policy</var> reset to timesharing. Disabling a scheduling
<var>policy</var> for a processor set has no effect on threads
currently assigned to that processor set unless
<var>change_threads</var> is TRUE, in which case their policies will
be reset to timesharing.
Only generic errors apply.
