This was an attempt to get upstream weston working per this issue commaai#16
Feel free to reuse any of this if it happens to be useful. I am giving up on the bounty as it's exceeded my resources, time and abilities to pursue it.
Build the system per the readme in the root directory first. This will ensure you have the prerequisite files and docker images that we'll use to build weston.
Run ./build.sh to compile weston in a docker and extract it out to disk.
Run ./install.sh to copy (over SSH) to your tici for testing. It won't actually install it.
And probably using "weston-prefix" instead of "/usr" as the prefix will have other problems and should be fixed, but this was just a quick test to see how difficult it would be and what problems we'd run into after the build and install process succeeds.
For testing purposes I ended up doing the following (after build and install) on the tici itself over SSH, as root:
Allowed writing to /:
mount -o rw,remount /
Copied the weston files into /weston-prefix (since that's what I defined as the prefix during build):
mv /home/comma/weston-prefix/ /weston-prefix
Ran ldconfig so that it can find the shared libs (libweston):
ldconfig /weston-prefix/lib/aarch64-linux-gnu/
Created this script based on the systemd service for weston:
#!/bin/bash
XDG_RUNTIME_DIR=/var/tmp/weston
echo 0 > /sys/class/backlight/panel0-backlight/brightness
sleep 0.1
echo 1023 > /sys/class/backlight/panel0-backlight/brightness
/usr/comma/modetest -M msm_drm -s 26@111:1080x2160-60
/usr/comma/modetest -M msm_drm -s 26@111:1080x2160-60
sleep 1
mkdir -p $XDG_RUNTIME_DIR
chown -R comma: $XDG_RUNTIME_DIR
mkdir -p /data/misc/display
echo 0 > /data/misc/display/sdm_dbg_cfg.txt
LD_LIBRARY_PATH=/weston-prefix/lib/aarch64-linux-gnu
/weston-prefix/bin/weston --idle-time=0 --tty=1 --config=/usr/comma/weston.ini #-B drm-backend.so
Disable the comma and weston services:
systemctl disable comma weston
This way I could reboot and try the script out...
I would run this normally to see what errors I would get, and they are the same I posted below.
The errors below are from the actual service file (extracted using journalctl after a reboot) after copying /weston-prefix into /usr just to see what happens prior to writing this note indicating that I am giving up on this and reflashing back to stock.
See the log below. Based on my understanding of the error below, it appears that weston is looking for /usr/lib/dri/msm_drm_dri.so which does not exist on the tici or in the build. I'll post the output files that would be created after you run build.sh right after the weston startup logs below:

so i just did a quick search on my tici and i see this:
/usr/lib/aarch64-linux-gnu/dri/msm_dri.so
and if i look at the error i see
Nov 21 17:07:53 tici bash[49399]: MESA-LOADER: failed to open msm_drm: /usr/lib/dri/msm_drm_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/aarch64-linux-gnu/dri:$${ORIGIN}/dri:/usr/lib/dri)
so i wonder if the path and name are just incorrect... what happens if i just symlinked that ?
nah just segfaults
