About

The iotools package provides a set of simple command line tools which allow access to hardware device registers. Supported register interfaces include PCI, IO, memory mapped IO, SMBus, CPUID, and MSR. Also included are some utilities which allow for simple arithmetic, logical, and other operations.

If you ever have to debug hardware, you could probably use these tools.

Building

iotools currently does not use an autoconf script or anything similar to build. iotools has only been tested to run and build on Linux. Additionally, it is assumed that gcc is being used to build. In order to build iotools, one just has to type make.

There are a few options that can be used during the build.

• DEBUG - If set to 1, debugging symbols will be generated in the binaries. The build currently turns this option on if the DEBUG variable has not been assigned.

• STATIC - If set to 1, the binary is linked statically. The build currently turns this option on if the STATIC variable has not been assigned.

• CROSS_COMPILE - This variable can be set to a path of another gcc. The build will use the compiler pointed to by CROSS_COMPILE.

Usage

Depending on environmental constraints, any of the commands provided by iotools can be accessed either implicitly using the installed symlinks or explicitly through the iotools binary.
