Just to throw out a single data point for the curious, video support for Skylake on master seems to be working pretty well for me.
At first there was a lot of tearing and corruption (usable, sort of), but using "uxa" instead of "sna" acceleration seems to have fixed things so far: /etc/X11/xorg.conf.d/20-intel.conf (taken from the Arch wiki): Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection Trying to watch youtube was pretty painful, but it works well for what I do (lots of text, light web browsing). FWIW, using "sna" and the "tearfree" option didn't improve the corruption.
