NAME

irqbalance - distribute hardware interrupts across processors on a multiprocessor system

SYNOPSIS

irqbalance [debug | oneshot]

DESCRIPTION

irqbalance is a Linux daemon that distributes interrupts over the processors and cores you have in your computer system. The design goal of irqbalance is to do find a balance between power savings and optimal performance. To a large degree, the work irqbalance does is invisible to you; if irqbalance performs its job right, nobody will ever notice it's there or want to turn it off.

OPTIONS

debug
Prints debug messages on stdout.
oneshot
Only do a one shot setup.

ENVIRONMENT

IRQBALANCE_BANNED_CPUS
Bitmap of CPUs that are banned from IRQ balancing
IRQBALANCE_ONESHOT
Same as the oneshot option mentioned above.
IRQBALANCE_DEBUG
Same as the debug option mentioned above.
IRQBALANCE_BANNED_INTERRUPTS
Interrupt that don't get balanced 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.
