Cat cpuinfo linux 64 Bit#

CPU architecture: AArch64 means 64 bit ARM board:.WARN_TAINT_ONCE(diff, TAINT_CPU_OUT_OF_SPEC, * Mismatched CPU features are a recipe for disaster. Features are evaluated by cpuinfo code, and only show if all cores support them /* All Serialized cores are shown in list with line breaks instead of separated processors. But by looking directly at /proc/meminfo, more details are revealed: MemTotal Total amount of physical RAM, in kilobytes. In fact, the output of the free command is similar in appearance to the contents and structure of /proc/meminfo. The /proc/cpuinfo virtual file contains a lot of information about the CPUs installed in our system. The following methods show the most useful tools, which are installed by default on almost any Linux distribution. This is the expected output to Arm based processors. Much of the information here is used by the free, top, and ps commands. Obtain CPU information via command line There are several command line utilities we can use to obtain CPU information on Linux. Processor : AArch64 Processor rev 3 (aarch64)įeatures : fp asimd evtstrm aes pmull sha1 sha2 crc32 It does not look quite right to me because I used to seeing cpu information present for each core (something like shown in Number of processors in /proc/cpuinfo).ĭoes the output of /proc/cpuinfo indicate a problem with the board or its configuration? Or is this output expected with some dev boards?ĪRM Cortex A53 (octa-core): $ cat /proc/cpuinfo I also noticed a cat of /proc/cpuinfo is returning something that does not look quite right, but I'm not sure if its cause for concern. I observed the self tests are running a little slower than expected, so I'm mildly investigating it. Linux hikey 3.18.0-linaro-hikey #1 SMP PREEMPT Mon Nov 30 00:11: The board provides two Cortex-A53 processors, provides eight cores, and uses Linaro Linux: $ uname -a I purchased it for testing a couple of libraries on ARM64 cpu architecture.

I have a LeMaker HiKey development board.
