This is the model. Although internally the blob is divided into chunks
that can be run separately, folks outside Intel have no visibility into
which chunk tests which circuits (even *inside* ... I don't know what
each chunk does :-) )

How often will updates occur? No idea. Since this is new, I'd expect
that there might be some improvements when there is feedback from
large CSPs running on many more systems than we have.

One of our early implementations included extra sysfs hooks to only
test specific chunks ... but we dropped that complexity as there's no
way for end users to decide which chunks to run.

So the posted series just iterates all chunks for a core.
