DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
The PCI Utilities package contains various utilities dealing with the PCI bus, and also a library for portable access to PCI configuration registers. It includes `lspci' for listing all PCI devices (very useful for debugging of both kernel and device drivers) and `setpci' for manual configuration of PCI devices.
Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard. This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag, and a lot of other details of varying level of interest and reliability, depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots and memory module slots, and the list of I/O ports.
smartmontools contains utilities that control and monitor storage devices using the Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) system built into ATA and SCSI hard drives. This is used to check the reliability of the hard drive and to predict drive failures. Version 5.x is designed to comply with the ATA/ATAPI-5 specification. Future releases will comply with the ATA/ATAPI-6 and ATA/ATAPI-7 specifications. It is meant to be an up-to-date replacement for the ucsc-smartsuite and smartsuite packages, and is derived from that code.
IPMItool is a simple command-line interface to systems that support the Intelligent Platform Management Interface (IPMI) specification. It provides the ability to read the SDR and print sensor values, display the contents of the SEL, print FRU information, read and set LAN configuration parameters, perform remote chassis power control, and act as a serial over LAN client. It can work with IPMI-over-LAN (both version 1.5 and 2.0) interfaces as well as the system interface provided by a kernel driver such as OpenIPMI.
