# irqbalance is a daemon process that distributes interrupts across
# CPUS on SMP systems.  The default is to rebalance once every 10
# seconds.  This is the environment file that is specified to systemd via the
# EnvironmentFile key in the service unit file (or via whatever method the init
# system you're using has.
#
# ONESHOT=yes
#    after starting, wait for a minute, then look at the interrupt
#    load and balance it once; after balancing exit and do not change
#    it again.

# IRQBALANCE_BANNED_CPUS
#    64 bit bitmask which allows you to indicate which cpu's should
#    be skipped when reblancing irqs.  Cpu numbers which have their
#    corresponding bits set to one in this mask will not have any
#    irq's assigned to them on rebalance
