NAME
irqtune − A Linux IRQ Priority Optimizer
SYNOPSIS
irqtune [options] [master] [slave]
DESCRIPTION
This manual
page explains the way to use the irqtune program.
This program changes the IRQ priority of devices to allow
devices that require high priority and fast service (e.g.
serial ports, modems) to have it.
With irqtune, a 3X speedup of serial/modem throughput is
possible.
USAGE
irqtune
[options] [master] [slave]
arguments:
master -- high priority IRQ on PIC master (DEFAULT: 3)
slave -- high priority IRQ on PIC slave (DEFAULT: 14)

-h -- display help

-x -- show inactive devices in table
error control options:
