![]() Running the code on my computer I get the following result. To work it requires that you have pup installed. Instead, application programmers can easily use HWCAP on Linux and the NDK on Android. For example, we want to check the core of the CPU: cat /proc/cpuinfo grep 'cpu cores'. The popular way of detecting the features at runtime by parsing /proc/cpuinfo is not portable to ARMv8-A and existing code will not work without tricky changes. I've heard the RPi manufacturers can't change this without a lot of hassle, $ cat /proc/cpuinfoįeatures : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32īCM2835 is what the Linux Kernel reports for ALL Raspberry Pi SBC. Below is a bash script that automatically finds the architecture code name for your CPU using /proc/cpuinfo and. If you think too much information is easy to get confused, you can use the grep command to output only the fields you want to view. The lscpu command gathers the CPU details such as number of CPUs, threads, cores, sockets, and Non-Uniform Memory Access (NUMA) nodes. The file /proc/cpuinfo displays what type of processor your system is running including the number of CPUs present. cpuinfo is a library to detect essential for performance optimization information about host CPU. In Linux, BogoMips can be easily obtained by searching the cpuinfo file. I could swear the ARM A72 was supposed to be ARMv8, but I could be wrong.Īlso I thought it was Broadcom BCM2711. Method 1- Check CPU information using lscpu The lscpu command line utility collects CPU architecture information from sysfs and architecture-specific libraries like /proc/cpuinfo. BogoMips (from bogus and MIPS) is a crude measurement of CPU speed made by the Linux.
