+# 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).
+
+#
+# IRQBALANCE_ONESHOT
+#    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_ONESHOT=
+
+#
+# IRQBALANCE_BANNED_CPUS
+#    64 bit bitmask which allows you to indicate which CPUs should
+#    be skipped when reblancing IRQs.  CPU numbers which have their
+#    corresponding bits set to one in this mask will not have any
+#    IRQs assigned to them on rebalance.
+#
+#IRQBALANCE_BANNED_CPUS=
+
+#
+# IRQBALANCE_BANNED_INTERRUPTS
+#    Interrupts that don't get banlanced as list (separation character
+#    doesn't matter). For example broken chipsets don't allow the timer
+#    interrupt to be set to another CPU than the first, and with this
+#    option that policy can be applied.
