![]() It's not a crazy idea to have a cpu cap field output from 'xm info', but we would need a feature request for that, since the lack of it isn't a bug. ![]() cpu model + bios revision, for guessing isn't sufficient), is to just reboot to BIOS or to a bare-metal kernel. If you are aware of the directory structure in Linux, you already know that proc is a special directory in. we > should really show the same number in /proc/cpuinfo which means adding. Other commands to check CPU information in Linux. Again, open the terminal, key-in: cat /proc/cpuinfo (Please do note there is a space after the cat. Is the use of the serial-number string property already. I'm afraid the best we'll be able to do for the case that someone gets on a machine they are unfamiliar with, and needs to check capabilities that dmidecode doesn't report (and some heuristic, e.g. Every Raspberry Pi has a unique serial number. While it's true that vmx isn't there, I have these extra flags from dmidecode that we've lost from cpuinfo after masking out the features grep Serial /proc/cpuinfo Serial : 1651660a0642ebb0 (taken from my A20 based SoC, Lamobo R1 aka Banana Pi R1 and ArmBian/Jessie with kernel 4.5.2) grep Serial /proc/cpuinfo Serial : 64355040058f0d000000 (taken from my H3 based Soc, Orange Pi One with Armbian/Jessie kernel 3. On my system dmidecode gives the same output for a bare-metal -164 kernel that it does for a xen -190 kernel. Get the serial of the device from /proc/cpuinfo. So one should interpret this /proc/cpuinfo entry as a 4-core CPU with hyperthreading. Version: Intel(R) Xeon(R) CPU E5520 2.27GHz My understanding so far has been that different cores within the same physical CPU would have different core id, and if core id s are identical, this is due to hyperthreading. Signature: Type 0, Family 6, Model 26, Stepping 5ĬMOV (Conditional move instruction supported)įXSR (Fast floating-point save and restore) Board revision number and serial number are concepts that don't appear to exist in the arm64 architecture, but we will continue to make that. There got be some reason why this vmx is missing. When we do support arm64 it will be with the absolute minimum number of changes to the upstream kernel (ideally none), and the content of /proc/cpuinfo would not be high on the list of priorities. The report by dmidecode is consistent with /proc/cpuinfo. This corresponds to the dmidecode output: ID: FB 06 00 00 01 03 00 00 matches a 06FB CPUID, i.e. Thus in your case it’s the CPU itself which is returning the Intel (R) Xeon (R) CPU E5335 2.00GHz string. There is also a field inside the information of each processor field which says cou cores are 2.This still does not work even with dmidecode. Revision : 0000 Serial : 0000000000000000 But legacy board code kernel reports: busybox cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor. On x86, it uses the CPUID Processor Brand String feature, where supported. Now it says that there are 4 processors on the system.

On my laptop, I get the following output: While we often use the term 'Linux' (or sometimes GNU+Linux) to refer to the operating system, it's a kernel first and foremost. ![]() ![]() How does one interpret the information printed out by the following command in Linux
