@zhenyu:

1. gpg --receive-keys 79BE3E4300411886 38DBBDC86092693E

2. repo-ck.com, not ck-repo.com.

I will therefore stop commenting as I have :)

@graysky: sorry for delay, output of Kaby Lake system:
$ gcc -c -Q -march=native --help=target | grep 'march\|mtune'
-march= broadwell
-mtune-ctrl=
-mtune= generic

$ cat /proc/cpuinfo | grep 'model name' | uniq
model name : Intel(R) Core(TM) i3-7100 CPU @ 3.90GHz

@graysky @vp1981: weird it shows broadwell :S

I have host with

$ cat /proc/cpuinfo | grep 'model name' | uniq
model name : Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz

and

$ gcc -c -Q -march=native --help=target | grep 'march\|mtune'

gives me

-march= broadwell
-mtune-ctrl=
-mtune= generic

While on host with

$ cat /proc/cpuinfo | grep 'model name' | uniq
model name : Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz

the same 'gcc...' gives me

-march= skylake
-mtune-ctrl=
-mtune= skylake

I faced with this mismatch for Kaby Lake when was installing Archlinux on that new host. After some investigation I decided that -march|-mtune=skylake is appropriate for Kaby Lake processor.

P.S. It is curious enough that both processor on Intel site are categorized as 'Products formely...', not sure what that mean. See http://ark.intel.com/products/88193/Intel-Core-i5-6200U-Processor-3M-Cache-up-to-2_80-GHz and http://ark.intel.com/products/97147/Intel-Core-i5-7400-Processor-6M-Cache-up-to-3_50-GHz

Are you sure? On your kaby lake what is the output of:

gcc -c -Q -march=native --help=target | grep 'march\|mtune'

@SuperIce97: Ah thanks, I'll give it a try. :)

@francoism90: Kaby Lake has an identical architecture to Skylake (they just improved the manufacturing process which simply allows for higher clock speeds), so you could just use use the Skylake optimized version. You could compile it with native optimizations.

@graysky: thanks, will install generic instead. :)

There is no KL support in gcc v7.1.1. https://gcc.gnu.org/onlinedocs/
