The iotools package provides a set of simple command line tools that allow access to hardware device registers. Supported register interfaces include PCI, I/O, memory mapped I/O, SMBus, CPUID, and MSR. Also included are some utilities that allow for simple arithmetic, logical, and other operations. If you ever have to debug hardware, you could probably use these tools.
prettyprint is intended to provide an infrastructure and tools to describe and manipulate hardware registers and fields. Once described, it is possible to read and write fields symbolically. This allows one to browse the state of their hardware. Examples provided include simple state dumpers as well as a FUSE filesystem.
The "EeePC-optimized Kernel for Ubuntu" project aims to produce a set of pre-compiled kernel packages that have been specially tailored to the EeePC's hardware and power usage, and to deliver these packages on a dedicated repository hosted by the author. Delivering these kernel packages over a Debian-style repository ensures that future updates and patches can be automatically downloaded to your EeePC as they're released. Current support is available for Ubuntu v8.04 (Hardy Heron) on the EeePC 700, 900, 900A, 901, 1000, and 1000H models.
v4l-utils is a collection of various video4linux (V4L) and DVB utilities. libv4l is an accompanying collection of libraries that adds a thin abstraction layer on top of video4linux2 (V4L2) devices. The purpose of this layer is to make it easy for application writers to support a wide variety of devices without having to write separate code for different devices in the same class. It consists of 3 different libraries. libv4lconvert offers functions to convert from any (known) pixel format to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420. libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent of the drivers for those devices supporting v4l1 compatibility (which many v4l2 drivers do not). libv4l2 offers the v4l2 API on top of v4l2 devices, while adding support for the application transparent libv4lconvert conversion where necessary.
The lxi-control application is a command line utility for remote controlling LXI enabled devices. Typical devices include instruments such as power supplies, oscilloscopes, digital multimeters, signal generators, etc. The devices are controlled by sending SCPI commands via a LAN IP network to the devices. LXI is the successor to GPIB.
