![]() ![]() i just happened to try again after the release of 38, ended up using the minimal image, made it through a dnf update and it was working fine until just recently.Īnyone else running fedora on a rev 1.1 board? i’m open to try other suggestions before opening a bug report. if i swap over to a USB3 nic, no issues and it’s been rock solid, which should rule out userspace.Īt this point, i’m starting to think it’s my board revision because whenever i tried booting fedora aarch64 images in the past, they would all kernel panic.i can login or even ssh into it before it happens. lscpu (though I expect it will pull back the same info as can be found in /proc/cpuinfo worth a shot though) To get a better answer the community would likely need additional information such as the kernel version. if i’m using the onboard nic, it’ll boot up, reach the login prompt, then ~30 seconds later, it’ll kernel panic. Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Unx-like operating. ![]() ![]() However, on an up-to-date fedora 38 (minimal) install: more /proc/cpuinfo grep 'model name' head -n 1 more /proc/cpuinfo grep 'cpu MHz' for the meminfo file, I want to get total memory, memory free and total used. stable on ubuntu server 23.04 (just tested).stable on dietpi (raspbian / debian 12).ssd for storage, using a known good usb-to-sata adapter.Some said to use System. Its like the name of CPU, the speed of CPU, the used memory of RAM, the free memory of RAM and so on But I dont know how to get it. Public void Call(int level, ref CpuIdInfo cpuInfo) Im trying to develop simple program like Windows Gadget to show users about their hardware information. To display this information, just run lscpu in the terminal to see the info: We can see details such as: CPU architecture. _delegate = Marshal.GetDelegateForFunctionPointer(_codePointer) _delegate = (CpuIDDelegate) Marshal.GetDelegateForFunctionPointer(_codePointer, typeof(CpuIDDelegate)) Marshal.Copy(codeBytes, 0, _codePointer, codeBytes.Length) _codePointer = (ĪllocationType.COMMIT | AllocationType.RESERVE, Private delegate void CpuIDDelegate(int level, ref CpuIdInfo cpuId) īyte codeBytes = (IntPtr.Size = 4) ? x86CodeBytes : 圆4CodeBytes StringBuilder ret = new StringBuilder(16) Public static void AppendAsString(StringBuilder builder,uint value) There are a couple ways, one is to look at the /proc/cpuinfo. You can modify following Windows code for Linux (you need to change Virtual Alloc function) Lets take a look at how we can view CPU info on Ubuntu Linux. How can I tell whether my processor has a particular feature (64-bit instruction set, hardware-assisted virtualization, cryptographic accelerators, etc. Then you need get processor name via cpuid instruction or ARM equivalent. Also you can allocate memory and set it as executable and copy to it code which is calls cpuid.įirst you must detect CPU architecture (for Windows this can be done via environment variables PROCESSOR_ARCHITECTURE and PROCESSOR_ARCHITEW6432) - what processor is using (x86/x86_64/ARM/ARM64) You must use cpuid instruction (or OS functions that calls cpuid). This.regex = new Regex(pattern, RegexOptions.Compiled) Public CpuInfoMatch(string pattern, Action update) New size\s+:\s+(.+)", value => CacheSize = Conversion.ObjectToString(value))įoreach (string cpuInfoLine in cpuInfoLines)įoreach (CpuInfoMatch cpuInfoMatch in cpuInfoMatches) New MHz\s+:\s+(.+)", value => MHz = Conversion.ObjectToDouble(value)), New value => Stepping = Conversion.ObjectToInt(value)), New name\s+:\s+(.+)", value => ModelName = Conversion.ObjectToString(value)), New value => Model = Conversion.ObjectToInt(value)), New family\s+:\s+(.+)", value => CpuFamily = Conversion.ObjectToInt(value)), Use the cat command to display the data held in /proc/cpuinfo. New value => VendorId = Conversion.ObjectToString(value)), / Reads /proc/cpuinfo to obtain common values net core only mono, but I'm pretty sure it should work. net core you will most likely have to grab from nuget. On Linux I used the FreeCSharp class from the example in this link How to get available virtual and physical memory size under Mono? to create a class that can read cpuinfo. ![]()
