Solaris 7 3/99 Online Release Notes (SUNWrdm)

Processor Interrupt Control

Processor interrupt control can be used by system administrators and developers of real-time applications to control interrupt distribution in a multiprocessor system. It can improve the performance of applications running on the processors where interrupts were disabled.

It enables users to disable most interrupts on specified processors. This can be done by using the psradm(1m) command or p_online(2) system call for individual processors, or using the psrset(1m) command for all processors in a processor set.

For more information see the man pages, psradm(1M), p_online(2), and psrset(1M) .
