ARM64 – And Now… 8 Cores!

I had another ARM64 system on order for some time, and – unexpectedly – it shipped a few days ago..

It is an 8-core ‘Hikey’ board, based on the same 96Boards outline as the DragonBoard 410c..

So far, I have it booting – with the Linaro/Hikey 3.18 kernel – and have put Fedora 22 on it..

Fedora release 22 (Twenty two)
Kernel 3.18.0-linaro-hikey on an aarch64 (tty1)
.........
# uname -a
Linux rghikey 3.18.0-linaro-hikey #1 SMP PREEMPT Wed Jul 1 17:32:09 UTC 2015 aarch64 aarch64 aarch64 GNU/Linux

It is fascinating to see it boot, with eight ‘Tux’s in a row!

$ cat /proc/cpuinfo
Processor : AArch64 Processor rev 3 (aarch64)
processor : 0
processor : 1
processor : 2
processor : 3
processor : 4
processor : 5
processor : 6
processor : 7
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 
CPU implementer : 0x41
CPU architecture: AArch64
CPU variant : 0x0
CPU part : 0xd03
CPU revision : 3
Hardware : HiKey Development Board

At least this board does not need the Android fastboot to update the kernel image, and kernel compilation can more easily be done on the system itself, rather than cross-compiling..    Next stage will be to see if I can get the 4.1-rc4 Linaro kernel to boot successfully..
