Sorry, left one thing out. When running, if you do not have
GBM/Wayland enabled for Mali (or no Mali support), you should run
with:
weston --use-pixman
or:
weston-launch -- --use-pixman

Launching from SSH is a bit more complicated:
sudo weston-launch --user=$username --tty=/dev/tty3 -- --use-pixman

(Replace tty3 with the TTY of your choice: it must be in text mode.)

Once you have done this, you will find three issues:
  - passing -1 to drm_send_vblank event causes OOPS - now fixed in your tree
  - not sending pageflip events for same-fb flips causes Weston hang -
fixed with my patch, and I believe now fixed in atomic (though it may
still have some timing issues; I hope to get to review this early next
week)
  - not having a preclose hook causes OOPS when Weston exits in the
middle of rendering - fixed in
https://git.collabora.com/cgit/user/daniels/linux.git/commit/?h=wip/4.4.x/rockchip-drm-fixes&id=d14f21bcd7e7a1b9ca129c411a9da9c911037965
and the preceding commit, which I hope to re-send for 4.4 -fixes in
the next couple of days

Hope this helps.

Cheers,
Daniel
