libcpuid
|
|
========
|
|
|
|
libcpuid provides CPU identification for the x86 (and x86_64).
|
|
For details about the programming API, you might want to
|
|
take a look at the project's website on sourceforge
|
|
(http://libcpuid.sourceforge.net/). There you'd find a short
|
|
[tutorial](http://libcpuid.sf.net/documentation.html), as well
|
|
as the full [API reference](http://libcpuid.sf.net/doxy).
|
|
|
|
Configuring after checkout
|
|
--------------------------
|
|
|
|
Under linux, where you download the sources, there's no
|
|
configure script to run. This is because it isn't a good practice to keep
|
|
such scripts in a source control system. To create it, you need to run the
|
|
following commands once, after you checkout the libcpuid sources
|
|
from github:
|
|
|
|
1. run "libtoolize"
|
|
2. run "autoreconf --install"
|
|
|
|
You need to have `autoconf`, `automake` and `libtool` installed.
|
|
|
|
After that you can run `./configure` and `make` - this will build
|
|
the library.
|
|
|
|
`make dist` will create a tarball (with "configure" inside) with the
|
|
sources.
|
|
|
|
Testing
|
|
-------
|
|
|
|
After any change to the detection routines or match tables, it's always
|
|
a good idea to run `make test`. If some test fails, and you're confident
|
|
that the test is wrong and needs fixing, run `make fix-tests`.
|
|
|
|
You can also add a new test (which is basically a file containing
|
|
the raw CPUID data and the expected decoded items) by using
|
|
`tests/create_test.py`. The workflow there is as follows:
|
|
|
|
1. Run "cpuid_tool" with no arguments. It will tell you that it
|
|
has written a pair of files, raw.txt and report.txt. Ensure
|
|
that report.txt contains meaningful data.
|
|
2. Run "tests/create_test.py raw.txt report.txt > «my-cpu».test"
|
|
3. Use a proper descriptive name for the test (look into tests/amd
|
|
and tests/intel to get an idea) and copy your test file to an
|
|
appropriate place within the tests directory hierarchy.
|
|
|
|
For non-developers, who still want to contribute tests for the project,
|
|
use [this page](http://libcpuid.sourceforge.net/bugreport.php) to report
|
|
misdetections or new CPUs that libcpuid doesn't handle well yet.

Users
|
|
-----
|
|
|
|
So far, I'm aware of the following projects which utilize libcpuid:
|
|
|
|
* CPU-X (https://github.com/X0rg/CPU-X)
|
|
* fre:ac (https://www.freac.org/)
|
|
* ucbench (http://anrieff.net/ucbench)
|
|
* Multiprecision Computing Toolbox for MATLAB (https://www.advanpix.com/)
|
|
|
|
We'd love to hear from you if you are also using libcpuid and want your project listed above.
