Once a device has been described, prettyprint can find any instances of the device and produce a tree of objects which can be read from and written to symbolically. prettyprint includes a simple device description 'language'.

The second piece is prettyprint - a library and set of tools which allow you extract hardware data in human-readable form. It also includes a bunch of simple arithmetic and logical tools to make your scripting even easier. Currently iotools includes support for PCI, IO, memory mapped IO, MSR, CPUID, TSC, SMBus, and CMOS. With iotools you can write simple shell scripts to read the device information you need, process it, and write it back to the hardware. The first piece is iotools - a suite of simple command line tools which allow you to read and write hardware registers.

We're software guys, so the solution, of course, was to write some code! We thought some of you out there might find our work useful, so we're happy to release these tools. If you've never had to do this, let us assure you - it isn't much fun, especially when you have a few hundred bit fields to decode. Generally that means we need to examine a bunch of hardware registers and see how the device is configured. One of the most difficult and tedious things we do here in the Platforms Team is figure out what is going wrong with a new piece of hardware.
