![]() ![]() ![]() Please also note that if you run your kernel in a virtual machine, you only see the CPU cores dedicated to the VM guest. Also please note that if there is a htt in flags, you are running a hyper-threading CPU, which means that your mileage may vary. It will contain cpuinsecure if your kernel has the KPTI patch Ive found that the KPTI patch has this piece of code: / Assume for now that ALL x86 CPUs are insecure / setupforcecpubug (X86BUGCPUINSECURE) And after the kernel update, you get: bugs : cpuinsecure PS. Ho trovato due comandi per ottenere informazioni sulla mia CPU: cat /proc/cpuinfo e lscpu. Please note that you need to parse and compare the physical id, core id and cpu cores to get an accurate result, if you really care about the number of CPUs vs. While(getdelim(&arg, &size, 0, cpuinfo) != -1) #define _GNU_SOURCEįILE *cpuinfo = fopen("/proc/cpuinfo", "rb") Here is sample code that reads and prints the info to console, stolen from forums - It really is just a specialized cat command. SMP machines have information for each CPU. TwoĬommon entries are processor which gives CPU number andīogomips a system constant that is calculated during kernel If this is omitted, all processors are displayed. Syntax dbgsyntax cpuinfo Processor Parameters Processor Specifies the processor to be displayed. piraspberrypi4: cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor rev 3 (v7l) BogoMIPS : 108. The cpuinfo extension displays detailed information about the target computer's CPU. ![]() Ive heard the RPi manufacturers cant change this without a lot of hassle, though. Items, for each supported architecture a different list. I could swear the ARM A72 was supposed to be ARMv8, but I could be wrong. This is a collection of CPU and system architecture dependent ![]()
