I have a LeMaker HiKey development board. I purchased it for testing a couple of libraries on ARM64 cpu architecture. The board provides two Cortex-A53 processors, provides eight cores, and uses Linaro Linux:
$ uname -a Linux hikey 3.18.0-linaro-hikey #1 SMP PREEMPT Mon Nov 30 00:11:03 UTC 2015 aarch64 GNU/Linux
I observed the self tests are running a little slower than expected, so I'm mildly investigating it. I also noticed a
/proc/cpuinfo is returning something that does not look quite right, but I'm not sure if its cause for concern. 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).
Does the output of
/proc/cpuinfo indicate a problem with the board or its configuration? Or is this output expected with some dev boards?
