![]() If the kernel cares about a feature or KVM. Display Level 1,Level 2, Level 3 cache information, online status and minimum and maximum frequency. On x86, flags appearing in /proc/cpuinfo have an X86FEATURE definition in arch/x86/include/asm/cpufeatures.h. Thread(s) per core: 2, Number of threads a physical core contains.ĬPU(s): 8, Logical cores, number of CPU’s that are used by the Operating System. Socket(s): 1, Physical chip which is connected into the motherboard’s socket.Ĭore(s) per socket: 4, Number of physical cores a socket contains. Most of the information is self explanatory however some of the more important ones: You can check how your CPU is being used with the htop command. For example, a system with 16 CPUs lists information for CPUs 0-15. If such flag represents a hardware feature, it also means that the hardware supports it. The output from cpuinfo includes sections for every CPU in your system. If a given flag is present, it means that the kernel supports it and is currently making it available.
