Hello, I am getting some errors while doing make. Can you please tell how to fix that? Thanks.

Hi,

this is because you are using a newer kernel, which has changed quite a lot header files. I forgot which kernel I used back then, it is probably somewhere between 2.6 - 3.11.

this is emulator is outdated, if you plan to get PM perf numbers, I suggest use real intel DC PM
