Print_cpuinfo_example executable which is useful to print theĪvailable CPU instruction sets. If the API was called with an entry count larger > than necessary (e.g., KVMMAXCPUIDENTRIES), it would succeed, but the > nent field would continue to show a value larger than the actual number > of entries filled by the KVMGETCPUID2 API. When building the libraries, waf will also build the Get it from the official source: Direct download link: Both the 32-bit and 64-bit. You can change the output folder by passing a different Nessecary files needed to use the library (e.g. The final install step will create a folder containing all the Python waf install -destdir cpuid_install To configure and build cpuid, run the following commands: python waf configure Have some additional waf tools which can be found at waf. We use the waf build system to build the cpuid static library. Released version of the library: git clone Buildįetch the sources, and we also recommend that you switch to the last Run automated tests with different compilers like g++, clang and msvc. We have tested cpuid on various versions of Windows, Linux and Mac. Instruction sets detected on x86: FPU, MMX, SSE, SSE2, SSE3, SSSE3, SSE 4.1, SSE 4.2, PCLMULQDQ, AVX, AVX2 and AVX-512 extensions.Ĭpuid license is based on the BSD License.Vendor += string((const char *)&cpuID.Cpuid is a C++ library for CPU dispatching.
