Linux on MacBook Pro Late 2016 and Mid 2017 (with Touchbar)

Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se

Problems to solve

Unix sockets and its programming

Since cpu and the operating system is dividing the clock cycle to multiple devices, how to make the sound seems continuous?

Maybe it's done by sending "discrete" data to the audio card, and the audio card plays it "continuously"?

doc about using linux ( as a desktop maybe?)

for scientific surfing:

instsall shadowsocks-libev config it to run on 127.0.0.1:1080

however, with firefox, i could still only go on the sites that are not blocked, though I make sure that my ip is outside the greatwall. I contribute this problem to DNS pollution. For the log of sslocal shows that google.com is redirected to 0.0.0.0. With chrome, this problem never happens. Maybe chrome has some dns resolver overiding?
