drm-next-4.6-11-STABLE ... up to date?

[Doug Kirk]

I'm wondering if this branch has been kept up-to-date with all the activity
regarding the i915kms driver?

Also, I freshly installed 11-RC2 last night, and following the instructions
at https://github.com/FreeBSDDesktop/freebsd-base-graphics/wiki made a
kernel from drm-next-4.6-11-STABLE. However, it immediately panic'd at boot
with a kernel page fault. As it was at the end of my day, I didn't
investigate further, but may do so tonight.

My current goal is to get X running on my XPS13-9350 (Skylake i7, Iris
540 at 3200x1800). Do I need to be on 12-CURRENT to accomplish that?

Is there a single page somewhere detailing all the necessary steps to get X
running with the recent driver work? As I understand it, I need to:

    1) Build a kernel from the FreeBSDDesktop fork, because there's some
updated stuff needed by the i915kms driver;
    2) Build xorg-server, xf86-*, and mesa(?) from
https://github.com/FreeBSDDesktop/freebsd-ports-graphics using the
"xserver-mesa-next" branch to get X 1.18.
    3) Configure X to use the "intel" driver with "sna" acceleration;
    4) Profit!

Finally, a huge THANK YOU to Matt Macy and everyone else working to get
FreeBSD graphics & X11 up-to-date.
