Hi Floris,

Yes I've seen the news, it's pretty big release. Also it is not marked
as a beta, but as a stable release. Vulkan, Wayland and atomic KMS in
one go is surely quite exciting!

Andreas,

I've branched 364 from 361, and committed all needed changes to build
this new release. Fairly small set, usual symbols/ids/patch refresh, and
the infrastructure for the new drm kernel module.

This module is not needed by other modules, and in turn it depends only
on the nvidia-modeset module, so I've updated the modprobe rules
accordingly. Also it's source-only, there's no binary blobs like for the
others.

I haven't enabled modeset=1 by default, because when I try to enable it
manually the following error appears:

Upstream does not enable it either by default, which is a sign that it's
not completely stable yet.

DKMS builds fine for all architectures on all kernels, but the source
build does not work which is strange, but I don't think I've fully
tested it for the 361 release either so it's probably something to do
with the new kernel modules. I'll investigate in the next couple of
days.

I've run quick tests on my desktop (not on the laptop) and all seems
good, which is good news given the last releases where not very stable!
Ran a few games just fine, VLC + VDPAU and a WebGL page on Chrome. Will
try optimus + bumblebee tomorrow.

Do you think we could move experimental to 358 (and up) soon? Given how
many goodies came with this release, it's bound to attract a lot of
interest :-)

Kind regards,
Luca Boccassi
