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. Test/Benchmark intel-corei7-64 intel-skylake-64 (1) CppPerformanceBenchmarks (Test: Math Library) (1st) 5m 15.70s 4m 36.39s (2nd) 5m 16.37s 4m 36.51s (3rd) 5m 15.54s 4m 37.80s CppPerformanceBenchmarks is a set of C++ compiler performance benchmarks.

For this patch, 'bitbake world' gets successfully built with latest poky master. Signed-off-by: Naveen Saini <naveen.kumar.saini@intel.com> Signed-off-by: Anuj Mittal <anuj.mittal@intel.com> |
