MT8195 hardware

[gctucker]

There are currently no MT8195 cherry Chromebooks in the Collabora lab. A minimum of 5 is typically required to run KernelCI tests.

The goal of this task is to determine the capacity required to cover all the testing requirements and whether more devices should be sourced.

• Test load estimated for KernelCI and other projects using cherry in the Collabora lab
• Additional devices sourced if required
• All devices are set up with Depthcharge image and pass healthchecks
• All devices have the MT8192 initial Chromium OS image #1608 flashed on the eMMC
• Device type merged upstream in LAVA
• KernelCI YAML configuration entry added for running at least baseline tests

Enablement of cherry (codename tomato) in the lab is in progress; we have 7 devices operational in the Collabora LAVA lab (custom Depthcharge image flashed; passing LAVA health checks), 5 more units left to be added.

Documentation for the specific model we have in the lab: https://lava.pages.collabora.com/docs/boards/chromebooks/boards/cherry

LAVA device type template has been merged upstream: https://git.lavasoftware.org/lava/lava/-/blob/master/etc/dispatcher-config/device-types/mt8195-cherry-tomato-r2.jinja2
