is anyone aware about a method to get CPUID and brand string, as well as maybe even features, similar to MMX/SSE etc. Questions: How can I get the machine serial number and CPU ID in a Linux system? Modified Table 1. (e-> flags & KVM_CPUID_FLAG_SIGNIFCANT_INDEX))) return e;} return NULL;} EXPORT_SYMBOL_GPL (kvm_find_cpuid_entry); /* * Intel CPUID semantics treats any query for an out-of-range leaf as if the * highest basic leaf (i.e. Memory type, size, timings, and module specifications (SPD). Elixir Cross Referencer - Explore source code in your browser - Particularly useful for the Linux kernel and other low-level projects in C/C++ (bootloaders, C libraries...) Live … Getting processor information using cpuid instruction and inline assembly. A CPU tool for benchmarking the peak of floating points - pigirons/cpufp Intel tries very hard to be compatible with GCC on Linux and VC on Windows. Answers: Here is what the Linux kernel seems to use: static inline void native_cpuid(unsigned int *eax, unsigned int *ebx, unsigned int *ecx, unsigned int *edx) { … CPUID.0H:EAX) were requested. I'm fairly certain, ICL doesn't support GNU style inline assembly in Windows mode. nasm -f elf cpuid.asm ld -s -o cpuid cpuid.o 64bit x86 machines nasm -f elf cpuid.asm ld -s -m elf_i386 -o cpuid cpuid.o Info for non-Linux/x86 users. 12/98-012 Modified Figure 1 to add the reserved information for the Intel386 processors. detection for NEON in Linux ARM? For those of you are still interested but don't have access to Linux/x86 system here is the assembly code I wrote (everything after a ; is a comment): Mainboard and chipset. The a, b, c, and d constraints are used in the output to … In this post we are going to learn how to extract those information using inline assembly in c. Added the Processor serial number information returned when the CPUID instruction is executed with EAX=3. CPU-Z is a freeware that gathers information on some of the main devices of your system : Processor name and number, codename, process, package, cache levels. Real time measurement of each core's internal frequency, memory frequency. cpuid is a processor specific instruction used to get processor's information and features. Modified Figure 2. Sample code is highly appreciated. Modified cpuid3b.asm and cpuid3.c example code to check for, and identify, the Celeron processor, model 6. CPUID - Intel SGX Capabilities Detection (Extended) - cpuid_sgx.c It seems to lack any form of __cpuid and cpuid.h ain't existing also - at least on my distro (OpenSuSE12.3) It's not vital for … The input to cpuid (the variable "op") is passed to "asm" in the eax register, as cpuid expects it to. Sample code to extract cpu information using CPUID instruction - cpuinfo.cpp
