From 04510bfabd50bb33da8ccc5075a2c5163605d552 Mon Sep 17 00:00:00 2001 From: Naveen Saini Date: Wed, 21 Aug 2019 10:11:38 +0800 Subject: conf: add new machine intel-skylake-64 Add 64-bit new machine (intel-skylake-64) with -march=skylake and avx2 instruction-set set up. We do see a qemu-usermode failure at build time, on setup of avx2 instruction-set as QEMU does not support AVX instruction set. Check this: https://bugs.launchpad.net/qemu/+bug/1818075 So to bypass this issue disabling qemu-usermode for intel-skylake-64 machine. Due to above limitation and in order to not affecting existing machines, this new machine is being proposed to add. A quick performance comparision between intel-corei7-64 vs intel-skylake-64 machines Measurements are in time, taken by the benchmark tests. Less is better.

For this patch, 'bitbake world' gets successfully built with latest poky master.
