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
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.
cpu_state Integer value representing the state of the CPU: ENABLED(0), DISABLED(1) or
RESERVED(2). 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 example,
for RTE (Real Time Extensions) some processors are reserved specifically to
handle interrupts from RTE cards.
NOTE: N/A value may be returned in some fields if the value is not available or the feature not applica-
ble.
The following is the output of intctl -b (balancing interrupts).
The following interrupt migrations will be performed for balancing interrupts (algorithm selected:
driver_weight)
_____________________________________________________________________
Sl. Card Driver Intr From CPU ID To CPU ID
Num. H/W Path name ID (CPU H/W path) (CPU H/W path)
_____________________________________________________________________
1 1/0/8/1/1 fcd 1 0 (1/120) 7 (3/123)
2 1/0/8/1/0 fcd 1 0 (1/120) 6 (3/122)
3 1/0/0/1/0 igelan 1 0 (1/120) 5 (3/121)
4 1/0/0/3/0 c8xx 2 0 (1/120) 4 (3/120)
5 1/0/0/3/0 c8xx 1 0 (1/120) 4 (3/120)
6 1/0/0/2/1 c8xx 2 0 (1/120) 4 (3/120)
7 1/0/0/2/1 c8xx 1 0 (1/120) 4 (3/120)
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.
127
Do you wish to skip these migrations (y/n):y
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.
The following is a description of each of the columns in the table:
Sl. Num. Serial number (starting from 1) of all the migrations that will be performed for balanc-
ing of interrupts. These serial numbers can be used in selecting migrations that have
to be skipped.
Card H/W Path The hardware path of I/O cards whose interrupt is getting migrated.
Driver Name. The driver associated with the card.
Intr ID. The identity of the interrupt to be moved.
From CPU ID (CPU H/W path)
The CPU id and CPU hardware path to which the interrupt is currently bound and
the interrupt will be migrated off this CPU.
