py-cpuinfo's Issues

Subprocess stderr is sometimes printed to console

Change this:
p1 = subprocess.Popen(command, stdout=subprocess.PIPE)

to this:
p1 = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

Make test suite auto run on both python 2 and 3

Instead of having to run the test suite for each version of python manually. Make it run itself on all versions of python.

Change version number format

Right now our version numbers are 0.API_change.features. It should be changed to API_change.features.bug_fixes. So the current version of 0.2.7 would become 2.7.0

Wrong CPU frequency in get_cpu_info_from_proc_cpuinfo()

On line 867 of cpuinfo.py processor_hz is set to '01612.0' which overwrites the actual processor frequency. Why did you do that?

Make it work on Android

Looks like Android has /proc/cpuinfo. See if we can make it work on ARM and X86 versions.

Add list of all CPU flags in documentation

See list of flags:
https://en.wikipedia.org/wiki/CPUID#EAX.3D1:_Processor_Info_and_Feature_Bits
https://en.wikipedia.org/wiki/CPUID#EAX.3D7.2C_ECX.3D0:_Extended_Features

Provide (signed) release tarballs

Hi,

I'd like to package py-cpuinfo for Debian. It would be very convenient if you could provide release tarballs.

Additionally, you might consider signing your releases. You can find more informations about it here.

Cheers,
Hugo (hle)

Makefile is hard coded for python 2

Update the Makefile so it can work with python3 too.

Does not work on ARMv8 64-bit (aarch64) systems

While building tables package I noticed that py-cpuinfo does not work on AArch64 systems.

extra stuff

Looks like cpuinfo method to gather information about systems fails because it cannot figure out what's the actual speed of the system. Basically it gets default None and then helper functions are throwing exception and it backs out. If you cannot find the frequency maybe you should set it to 0 or -1.

You also need to add arch regexp for aarch64, there is no armv8-a in arch strings in any distribution as I know.

Remove has_blah methods

Instead of having both a has_blah() and blah() method. Just check if blah() exists. This will prevent errors where we forget to have both setup.

dmesg is missing extra Features in flags

We are missing the "Features2", "AMD Features", and "AMD Features2" CPU flags.

Combine data from all sources instead of picking one

Right now it picks data from the first source that returns something. The problem with this, is that each source only provides a few fields. If we get data from all the sources, we can combine all the fields. This should also remove coupling between data sources.

CPUID breaks on brands with many NULL terminators

We were assuming that all brand strings ended on one NULL terminator. But some have more:

"Intel(R) Core(TM) i5-4300U CPU @ 1.90GHz "

This causes a crash on such systems.

Not working on RHEL7.3 ppc64le

I have installed it by command "pip install py-cpuinfo" . However, while running the bazel tests in tenosrflow I am getting the following error
Exception: py-cpuinfo currently only works on X86 and some ARM CPUs.

After that I installed it from source . And for TF tests getting some different kind of error i.e. "KeyError: 'l2_cache_size" . PFA for more details.

CPUID failure segfaults Python

If something goes wrong when running the CPUID byte code, it crashes Python. We need to try running it is a subprocess to fix the problem.

get_cpu_info_from_cpuid breaks with Python3

Querying the CPUID register is broken in Python3

Please ship tests to pypi

Downstream developers love to test during their packaging efforts. PLease include the tests in your pypi tarball.

Missing AVX2 CPU flag on OS X

Apologies for the naive question, but will this package detect support for AVX2 instructions?

conda package (on conda-forge)

Since py-cpuinfo is a pure Python package, installation is of course not a big issue. However, some packages that have compiled C-extensions (like one of ours) might depend on it and those now often tend to provide conda packages to make installation easier. Only conda packages can be dependencies of conda packages, so that's why we created a conda package for py-cpuinfo on anaconda.org (https://anaconda.org/brian-team/py-cpuinfo) -- judging from the number of downloads, it's quite popular!
What do you think of having a package on conda-forge (http://conda-forge.github.io/) instead? I'd be happy to create the package recipe (again, for a pure Python package this is rather trivial) and I could list you and me as maintainers (or only you or only me if you prefer).

Add Arch to Readme

Add this to the readme:

Possible values for Arch field:
X86_32
X86_64
ARM_7
ARM_8
PPC_32
PPC_64
SPARC_32
SPARC_64

Add basic documentation

The readme.md page has a lot of duplicate info, and is missing a lot:

Remove second giant example output
Explain the structure of the retuned info object
Add python -m cpuinfo to list of ways to use it
Add a list of API calls and what they do
Add a list of supported OSes and their status

Not working on Red Flag Linux ppc64le

Hi everyone,I met a problem about py-cpuinfo to my OPENPOWER8 cpu.
When I try to use ESRALLY to stress my ES,ESRALLY say py-cpyinfo only support x86 or ARM.
Could you give me some adivce ?thanks

Doesn't work on an ARMv5TEJ KuroBox Pro

It would be awesome if this script worked with the ARMv5TEJ KuroBox Pro.

Here is the information that is gathered from your script and I'm available for other information as well:

system_info.txt

Please, consider supporting this. People running some of the original Raspberry Pi's (which are ARMv6 CPUs, IIRC) would also love to get this working.

Thanks,

Rogério.

On Windows use win32 cpuid function instead of registry

The Windows registry is missing newer flags like sse3, et cetera. See if we can use Python ctypes to call the win32 cpuid function instead.

System exit called if CPU is not supported

Hi,

i use py-cpuinfo in the Glances project (https://github.com/nicolargo/glances). On Raspberry Pi, if the CPU is not supported, Py-Cpuinfo call an (ugly) sys.exit(0) (https://github.com/workhorsy/py-cpuinfo/blob/master/cpuinfo/cpuinfo.py#L1478). It should be more "Pythonific" to raise an error.

Thanks in advance for the enhancement.

Add a test suite

Extract all the things that get cpu info into a DataSource object. Like:
DataSource.has_kstat
DataSource.kstat_m_cpu_info
DataSource.has_proc_cpuinfo
DataSource.proc_cpuinfo

That way we can override the methods to return hard coded strings. This will make it easier to test on different platforms.

Include py-cpuinfo version in output

It would be very useful to include the py-cpuinfo version number in the output:

$ python cpuinfo/cpuinfo.py
cpuinfo version: (3, 1, 0)
Vendor ID: GenuineIntel
Brand: Intel(R) Pentium(R) CPU G640 @ 2.80GHz
...

Make CPU flags uniform no matter the info source

Different tools (/proc/cpuinfo, lscpu, et cetera) have different names for CPU flags. Make a list of all of them, and make the output uniform.

Make it work on Raspberry Pi

See the commands to get the Hz:

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

Make test suite test real functions too

We have a problem where the test suite will work correctly with the mock objects. But fail with the real objects. So lets test the real thing too.

CPUID breaks test suite when SE Linux is on (Fedora 25)

I tried to build new update 0.2.6 on fedora 25 and here is what I get the output
https://kojipkgs.fedoraproject.org//work/tasks/3355/18353355/build.log which is

processor_brand string is Intel(R) Pentium(R) D CPU 3.20GHz

Make it work on a BeagleBone

We can get the Hz from the cpufreq-info command.

Importing is different depending on install method

If you install with pip or setup.py you have to do:

from cpuinfo import cpuinfo

to get the cpuinfo module. This is because the module cpuinfo is in a package called cpuinfo.

If you import directly from the cpuinfo.py file (as in you copied the file directly into your project). You can import like this:

import cpuinfo

This is super confusing. How do we make this consistent? I would prefer to do "import cpuinfo"

The ctypes.pythonapi.memmove call segfaults CPUID in Virtual Box

In Virtual Box some operating systems will segfault when CPUID calls ctypes.pythonapi.memmove. These include BSD, Cygwin, OSX, and Solaris. But Windows, Linux, and BeOS work.

Not working on Fedora 24 ppc64le

In Fedora, I tried to build latest 0.2.7 release and it is failing to build on architectures like s390(x), ppc(le64), arm(aarch64). I think previous versions were also failed to build.

May I know if this py-cpuinfo project should work on those architectures as well? The traceback I get while test suite execution is

Can this project be updated to support these other architectures?

Thanks.

Not working on OS X 10.12 Sierra

Not sure what may be causing this, and I didn't find any options for verbose output.

Calling cpuinfo.get_cpu_info() returns None on my machine, 2011 MBA running OS X 10.12.3. Getting the info with sysctl seems to work fine on the command line.

Happy to provide any additional info that may help debug this.

CPUID breaks when it returns nothing (Fedora 26)

Only works after commenting out the _get_hz_string_from_beagle_bone() part

get_cpu_info() always returned None. Some debugging showed that the line

hz_brand = output.split('current CPU frequency is')[1].split('.')[0].lower()

in _get_hz_string_from_beagle_bone throws an error. In get_cpu_info_from_proc_cpuinfo I commented the following block out

# Try getting the Hz for a BeagleBone
        if hz_advertised == '0.0':
            scale, hz_advertised = _get_hz_string_from_beagle_bone()
            hz_actual = hz_advertised

After that it worked.

FreeBSD Segfaults with Python2/3

I have written my own def for FreeBSD support as the standard dmesg -a | grep Features results in a segfault.

http://pastebin.com/nyjn38B8

Please incorporate this and add info = get_cpu_info_from_freebsd() just after the Windows block to fix the issue. Thanks.

Getting CPU info from dmesg fails on Linux but not BSD

It looks like there are 2 versions of dmesg, one that takes an "-a" argument, and one that does not. Plus they are formatted a little differently on Linux and BSD.

Not working on ARM64 odroid-c2

Not currently supported on aarch64.
I know it's duplicated here (#49), but the other guy has not provided the system_info.
No much info is is available on this particular board, so I think it is just fixing cpufreq-info output parsing.

system_info.txt

It is not obvious if Hz Raw is the current Hz, or the advertised Hz

We should have a tuple for the current Hz, and the advertised Hz:

hz_actual: 800 MHz
hz_advertised: 1.6000 GHz
hz_current_raw: (8000000, 0)
hz_actual_raw: (1600000000, 0)

This way we can use the numbers in comparisons.

Make a script for easy gathering of CPU info

The script should gather:

From Python:
sys.version_info
multiprocessing.cpu_count()
platform.uname()
platform.architecture()
platform.system()
platform.machine()

output of commands:
cpufreq-info
sestatus -b
dmesg -a
cat /proc/cpuinfo
sysctl machdep.cpu
isainfo -vb
kstat -m cpu_info
