Moving interrupts
If you have determined that you need to move one or more interrupts as explained in the
previous section, perform the following steps:
1. Choosing the target processor.
a) Use the intctl command to get a list of all interrupts and their associated
processors by entering:
/usr/contrib/bin/intctl
Use the intctl command to get a list of the interrupts on a particular processor by
entering:
/usr/contrib/bin/intctl -c <processor number>
Where <processor number> is the processor number associated with a particular
processor.
b) If there is a processor with no interrupts, select it and go to Step 2. Otherwise go to
(c).
c) If there is a processor with fewer interrupts than other processors, select it and go to
Step 2. Otherwise go to (d).
d) Simply choose another appropriate processor with a similar number of interrupting
devices and go to Step 2.
