via email:
"""
Right now we're working on converting the work we did on HW hint providing into
the BTF format, like we discussed in the last meeting. We're making decent
progress, and should be able to share something soon to see what people think.
We're also looking at how to connect the format specification with a
communication mechanism to the drivers to program them to provide the metadata.
Both of these are ongoing.
