Remarks. They also handle ebx register in case it is used for PIC code. ... Use __get_cpuid_max and __cpuid_count from Both gcc and clang have support for these. Make sure to install it before running it. ARM. The command cpuid dumps complete information about the CPU(s) collected from the CPUID instruction, and also discover the exact model of x86 CPU(s) from that information. Read raw hex information from FILE instead of from executions of the cpuid instruction. Stack Overflow: Getting Machine Serial number and CPU Id using c/c++ in Linux That page provides the definition for native_cpuid() that should be included as part of the C source file. (This option is the default.) detection for NEON in Linux ARM? If you use another compiler, you must check if that provides its own support of the x86 cpuid instruction. Header file . The intention of getcpu() is to allow programs to make optimizations with per-CPU data or for NUMA optimization. Both gcc and clang have support for these. ZFS on Linux - the official OpenZFS implementation for Linux. A new free online. -h,-H, --help Display help information. -i,--inst Use the CPUID instruction. 3. cpuid Command – Shows x86 CPU. (On some architectures, this is done via an implementation in the vdso(7).) A new free online conference! 2- go to linux 3- install GCC , lsUSB , Libusb-1.0.x , libusb-1.0-dev (from “Ubuntu software center” ) 4- drag and drop the APX.c file in your desktop 5- connect your tablet to the computer (through mini USB) and put it in APX mode 6- Now on computer fire up “Terminal” and type this code The information it provides is reliable. is anyone aware about a method to get CPUID and brand string, as well as maybe even features, similar to MMX/SSE etc. Linux ARM cpuid/cpubrand C++. Live Embedded Event. 1.简介在计算机领域中需要用到cpu信息的地方有很多。比如,在可信计算中,需要收集终端的软硬件的完整性信息,其中就包含cpu的信息;再比如,一些加密软件需要绑定cpu的某些信息,去生成加密密钥。本文就关于在linux平台下cpu信息的获取展开阐述。 cpu信息获取的方式有两种方式: 1. NOTES top Linux makes a best effort to make this call as fast as possible. They also handle ebx register in case it is used for PIC code. 0.00/5 (No votes) See more: C++.

Your posted code will work only with the Microsoft compiler which is part of Visual Studio because it uses the Microsoft specific header file intrin.h (and stdafx.h) and the MS compiler specific __cpuid, __cpuidex[] intrinsic function. This intrinsic stores the supported features and CPU information returned by the cpuid instruction in cpuInfo, an array of four 32-bit integers that's filled with the values of the EAX, EBX, ECX, and EDX registers (in that order).The information returned has a different meaning depending on the value passed as the function_id parameter.
