HWINFO(8) System configuration HWINFO(8) NAME
hwinfo - probe for hardware SYNOPSIS
hwinfo [ OPTIONS ] DESCRIPTION
hwinfo is used to probe for the hardware present in the system. It can be used to generate a system overview log which can be later used for support. OPTIONS
Note that running hwinfo without any options is roughly equivalent to 'hwinfo --all --log=-'. --<HARDWARE_ITEM> This option can be given more than once. Probe for a particular HARDWARE_ITEM. Available hardware items are: all, arch, bios, block, bluetooth, braille, bridge, camera, cdrom, chipcard, cpu, disk, dsl, dvb, fingerprint, floppy, framebuffer, gfxcard, hub, ide, isapnp, isdn, joystick, keyboard, memory, modem, monitor, mouse, netcard, network, partition, pci, pcmcia, pcm- cia-ctrl, pppoe, printer, redasd, reallyall, scanner, scsi, smp, sound, storage-ctrl, sys, tape, tv, uml, usb, usb-ctrl, vbe, wlan, xen, zip --short Show only a summary. Use this option in addition to a hardware probing option. --listmd Normally hwinfo does not report RAID devices. Add this option to see them. --only DEVNAME This option can be given more than once. If you add this option, only data about devices with DEVNAME will be shown. --save-config SPEC Store config for a particular device below /var/lib/hardware. SPEC can be a device name, an UDI, or 'all'. This option must be given in addition to a hardware probing option. --show-config UDI Show saved config data for a particular device. --map If disk names have changed (e.g. after a kernel update) this prints a list of disk name mappings. Note that you must have used --save-config at some point before for this can work. --debug N Set debug level to N. The debug info is shown only in the log file. If you specify a log file, the debug level is implicitly set to a reasonable value. --verbose Increase verbosity. Only together with --map. --log FILE Write log info to FILE. --dump-db N Dump hardware data base. N is either 0 for the external data base in /var/lib/hardware, or 1 for the internal data base. --version Print libhd version. --help Print usage. ENVIRONMENT
hwprobe can hold a comma-separated list of probing flags preceded by '+' or '-' to be turned on or off. To get a complete list of supported flags, run 'hwinfo -all' (note: not '--all') and look at the top of the output. hwinfo also looks at /proc/cmdline for a hwprobe option. EXAMPLES
- show all disks hwinfo --disk - just an overview hwinfo --short --block - show a particular disk hwinfo --disk --only /dev/sdb - save disk config state hwinfo --disk --save-config=all - try 4 graphics card ports for monitor data (default: 3) hwprobe=bios.ddc.ports=4 hwinfo --monitor - monitor detection runs the Video BIOS to get the monitor data; dump a complete BIOS code execution trace to the log hwprobe=bios.ddc.ports=1,x86emu=trace:dump:trace.only=0:dump.only=0 hwinfo --monitor --log=foo FILES
/var/lib/hardware/hd.ids External hardware data base (in readable text form). Try the --dump-db option to see the format. /var/lib/hardware/udi Directory where persistent config data are stored (see --save-config option). BUGS
Not all hardware can be detected. SEE ALSO

LSHW(1) LSHW(1) NAME
lshw - list hardware SYNOPSIS
lshw [ -version ] lshw [ -help ] lshw [ -X ] lshw [ [ -html ] [ -short ] [ -xml ] [ -json ] [ -businfo ] ] [ -dump filename ] [ -class class... ] [ -disable test... ] [ -enable test... ] [ -sanitize ] [ -numeric ] [ -quiet ] DESCRIPTION
lshw is a small tool to extract detailed information on the hardware configuration of the machine. It can report exact memory configura- tion, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines (PowerMac G4 is known to work). It currently supports DMI (x86 and IA-64 only), OpenFirmware device tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA (only tested on x86), SCSI and USB. -version Displays the version of lshw and exits. -help Displays the available command line options and quits. -X Launch the X11 GUI (if available). -html Outputs the device tree as an HTML page. -xml Outputs the device tree as an XML tree. -json Outputs the device tree as a JSON object (JavaScript Object Notation). -short Outputs the device tree showing hardware paths, very much like the output of HP-UX's ioscan. -businfo Outputs the device list showing bus information, detailing SCSI, USB, IDE and PCI addresses. -dump filename Dump collected information into a file (SQLite database). -class class Only show the given class of hardware. class can be found using lshw -short or lshw -businfo. -C class Alias for -class class. -enable test -disable test Enables or disables a test. test can be dmi (for DMI/SMBIOS extensions), device-tree (for OpenFirmware device tree), spd (for memory Serial Presence Detect), memory (for memory-size guessing heuristics), cpuinfo (for kernel-reported CPU detection), cpuid (for CPU detection), pci (for PCI/AGP access), isapnp (for ISA PnP extensions), pcmcia (for PCMCIA/PCCARD), ide (for IDE/ATAPI), usb (for USB devices),scsi (for SCSI) or network (for network interfaces detection). -quiet Don't display status. -sanitize Remove potentially sensitive information from output (IP addresses, serial numbers, etc.). -numeric Also display numeric IDs (for PCI and USB devices). BUGS
lshw currently does not detect Firewire(IEEE1394) devices. Not all architectures supported by GNU/Linux are fully supported (e.g. CPU detection). "Virtual" SCSI interfaces used for SCSI emulation over IDE are not reported correctly yet. NOTES
lshw must be run as super user or it will only report partial information. FILES
/usr/local/share/pci.ids /usr/share/pci.ids /etc/pci.ids /usr/share/hwdata/pci.ids A list of all known PCI ID's (vendors, devices, classes and subclasses). /proc/bus/pci/* Used to access the configuration of installed PCI busses and devices. /proc/ide/* Used to access the configuration of installed IDE busses and devices. /proc/scsi/*, /dev/sg* Used to access the configuration of installed SCSI devices. /dev/cpu/*/cpuid Used on x86 platforms to access CPU-specific configuration. /proc/device-tree/* Used on PowerPC platforms to access OpenFirmware configuration. /proc/bus/usb/* Used to access the configuration of installed USB busses and devices. /sys/* Used on 2.6 kernels to access hardware/driver configuration information. EXAMPLES
lshw -short Lists hardware in a compact format. lshw -class disk -class storage Lists all disks and storage controllers in the system. lshw -html -class network Lists all network interfaces in HTML. lshw -disable dmi Don't use DMI to detect hardware. SEE ALSO
