ja:Hw-probe zh-hans:Hardware probe

hw-probe (hardware probe) is a Perl program which is able to:

• collect output from a number of utilities—such as lspci(8) and hwinfo(8)—and some other logs,

analyze collected data:

• check if drivers were loaded,

• check for driver or hardware operability status (partially),

• benchmark (quick and simple)—by using several tools such as 7-Zip and hdparm,

• contribute this information to the Linux Hardware Database.

Statistics that is based on the database data—both current and historical one—can be viewed at Trends.

Installation

Install the hw-probe package. Additional packages that might be useful:

• 7zip — benchmarking (with --check-7z or --check-extended option),

• hdparm — probing and benchmarking storage devices,

• memtester — memory testing during benchmarking,

• mesa-utils — probing and benchmarking OpenGL on X,

• perl-json-xs — JSON-formatted devices.json output file.

Usage

Make a probe:

# hw-probe --all --upload

Decode ACPI tables (requires acpica package):

# hw-probe --all --upload --decode-acpi

Benchmarking

Specific benchmarking options:

• --check-7z — test CPU and RAM with 7z b,

• --check-cpu — test CPU by applying md5sum(1) to 512 MB of zeroes from dd(1),

• --check-graphics — test GPU with glxgears,

• --check-hdd — test storage devices with hdparm(8),

• --limit-check-hdd=number — limit number of drives to be tested—i.e. test only the first number of them,

  --check-memory — test 8 megabytes of RAM with memtester(8).

Perform all benchmarking tests mentioned above, including 7-Zip one:

# hw-probe --check-extended
