intctl command
The intctl command is a HP-UX tool that allows you to manage I/O interrupts among active
CPUs.
For HP-UX 11i v1, intctl is not installed by default with HP-UX, but you can obtain the software
for intctl from the HP-UX Software Pack for 11i v1. Software Pack is available from the Software
Pack DVD included with the HP-UX 11i OE DVDs or from the Software Depot website at:
http://www.hp.com/go/softwaredepot
For more information, see the Interrupt Migration Product Note available at http://docs.hp.com or
see the intctl(1M) manpage.
Notes
• Interrupts are processed only by bound CPUs.
• Therefore, when managing I/O interrupts with intctl, you can manage the I/O interrupts
only among the bound CPUs.
• Further, disabling interrupts on a bound CPU does not convert the bound CPU into an
unbound CPU.
