That Pub/Sub interface is a Google API for sending your testing results to
KCIDB. It doesn't allow querying data.

Great!

Last week we have deployed support for submitting the `compatible` values from
the top of the device tree of the machine executing a test, as part of test
environment's information. Here's the I/O JSON schema for that:

https://github.com/kernelci/kcidb-io/blob/40f6d20f4e76d8d2b7288390003082f77d0aabb2/kcidb_io/schema/v04_04.py#L577-L602

In the database that is stored in a string array column. We're still
researching how to best query it and which indexes we would need, so a query
like "give me all tests which executed on Quallcomm boards (`qcom`?)" might be
very slow.

Here's a sample of vendors we're getting in the test results in our
"playground" database (from Maestro only so far), on our WIP dashboards:

https://fresh2-kcidb-grafana-m6io3uhhiq-uc.a.run.app/goto/R9b0F5qIg?orgId=1

And no, we don't have the "vendor" dashboard yet :D

Great! Could you give me a Google account email, so I could give it access to
the server?
