i
intctl(1M) intctl(1M)
cpu cell The cell number of the cell to which the CPU is connected.
intr type A character representing the interrupt type:
L line based interrupt
T transaction based interrupt
M MSI based interrupt
X MSI-X based interrupt
intr ID The identity of the interrupt to be moved.
card description
A brief description of the interface card.
cpu path The hardware path of the CPU (relevant with the
-s and -r options). The cpu path
and cpu state fields are displayed when specifying the
intctl -p option.
cpu state Integer value representing the state of the CPU: ENABLED(0), DISABLED(1) or
RESERVED(2) (relevant with the -s, -r, and
-l options). These states are interrupt
states and do not have any relationship to the thread state.
ENABLED The CPU is capable of receiving external interrupts from interface cards.
DISABLED The CPU cannot handle external interrupts from interface cards.
RESERVED The state is reserved to receive interrupts from specific cards, for exam-
ple, for RTE (Real Time Extensions) some processors are reserved
specifically to handle interrupts from RTE cards.
The
cpu path and cpu state fields are displayed when specifying the intctl -p
option.
NOTE: N/A value is returned in some fields if the value is not available or the feature is not applica-
ble.
The following output is an example from the intctl -b command for balancing interrupts.
Following interrupt migrations will be performed for balancing interrupts (algorithm selected:
driver_weight)

Please select the migrations you want to skip.
Comma separated serial numbers or ’all’ or ’none’ : 1,2,7
Following migrations (serial number(s)) will be skipped.

intctl: Moved the interrupt: 1, of card 1/0/0/1/0, driver igelan, from CPU:0 to CPU:5
intctl: Moved the interrupt: 2, of card 1/0/0/3/0, driver c8xx, from CPU:0 to CPU:4
intctl: Moved the interrupt: 1, of card 1/0/0/3/0, driver c8xx, from CPU:0 to CPU:4
intctl: Moved the interrupt: 2, of card 1/0/0/2/1, driver c8xx, from CPU:0 to CPU:4
Balancing of interrupts done.
