Get cpuinfo linux12/14/2023 If py-cpuinfo does not work on your machine, run the script: python tools/get_system_info.pyĪnd create bug report with the generated “system_info.txt” file. There are quite a few commands on linux to get those details about the cpu. Please report a Bug if you suspect any of this information is wrong. get_cpu_info () # Or use /proc/cpuinfo #info = cpuinfo.get_cpu_info_from_proc_cpuinfo() # Or use the Windows registry #info = cpuinfo.get_cpu_info_from_registry() # Or use sysctl #info = cpuinfo.get_cpu_info_from_sysctl() # Or use CPU CPUID register #info = cpuinfo.get_cpu_info_from_cpuid() # Print some CPU values print ( 'Vendor ID: '. This is done this way, because it is much more flexible with new architectures than to supply the information. Here is the table of content of this tutorial: System Information. You can use command like more, less or grep to see the contents of this file. It is used as an interface to kernel data structures. Proc (/proc) file system provides information about CPU and their speed which is a pseudo-filesystem. However, well be using the psutil library in Python so it can run on all operating systems and get almost identical results. Linux /proc/cpuinfo file contains details about individual cpu cores. Run as a script $ python cpuinfo/cpuinfo.py Vendor ID: GenuineIntel Hardware Raw: Brand: Intel (R ) Core (TM ) i5-4440 CPU 3.10GHz Hz Advertised: 3.1000 GHz Hz Actual: 3.0794 GHz Hz Advertised Raw: ( 3100000000, 0 ) Hz Actual Raw: ( 3079444000, 0 ) Arch: X86_64 Bits: 64 Count: 4 Raw Arch String: x86_64 L2 Cache Size: 6144 KB L2 Cache Line Size: 0 L2 Cache Associativity: 0 Stepping: 3 Model: 60 Family: 6 Processor Type: 0 Extended Model: 0 Extended Family: 0 Flags: apic, clflush, cmov, constant_tsc, cx8, de, fpu, fxsr, ht, lahf_lm, lm, mca, mce, mmx, msr, mtrr, nopl, nx, pae, pat, pge, pni, pse, pse36, rdtscp, rep_good, sep, sse, sse2, ssse3, syscall, tsc, vme Run as a library import cpuinfo # Have the library pick the best method for getting your CPU info info = cpuinfo. As far as I know and I have dealt with those sort of things, the way you do get that info from the system is by reading /proc/cpuinfo - you can read it from inside an application by using fopen () and fgets () for example. There are quite popular tools to extract system and hardware information in Linux, such as lshw, uname and hostnamectl. Querying the CPUID register (Intel X86 CPUs) These approaches are used for getting info: Windows, BSD, Solaris, Cygwin, Haiku, and BeagleBone. It does not requireĪny compilation(C/C++, assembly, et cetera) to use. To see how this works, try these two commands : head / proc / cpuinfo. We can determine the CPU usage by taking the percentage of time spent idling and subtracting it from 100. CPU Usage can only be measured over a specified interval of time. Py-cpuinfo should work without anyĮxtra programs or libraries, beyond what your OS provides. Manual pages cover the essentials, but there are many more ways to get online. email protected cat /proc/cpuinfo grep core core id : 0 cpu cores : 1 On the other hand, CPU usage is the percentage of time a CPU takes to process non-idle tasks. Note in both cases the model contains a newline, these solutions are compatible with any CPU.Py-cpuinfo gets CPU info with pure Python. While (fgets(line, sizeof(line), fp) != NULL) '", "r") Ĭhar * model = (*line = ' ') ? line + 1 : line Model name : Intel(R) Core(TM) i7-2600 CPU 3.40GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good nopl xtopology nonstop_tsc pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 popcnt aes xsave avx hypervisor lahf_lmĪddress sizes : 36 bits physical, 48 bits virtualįprintf(stderr, "cannot open /proc/cpuinfo !") To get all the CPU information of the system, run the below command: lscpu The output shows the system CPU features: Architecture: X8664, which shows the CPU is 64bit x86 type. Read the file /proc/cpuinfo and look at the line(s) containing "model name" (at least for a Debian / CentOS / OpenSuse, check for your Linux)Įxample on my raspberrypi : $ cat /proc/cpuinfoįeatures : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32Įxample under CentOS : ~]$ cat /proc/cpuinfo Method 1: Using lscpu Command The lscpu (list CPU) command utility is used to obtain details about the CPU architecture.
