UNCLASSIFIED

Hi,

Moving logic down the hierarchy (or up the hierarchy into fpgaTop) so
that mkFTop is purely structural (instances wired together) would help
me greatly.

Hand writing code that may be automated in the future is not an issue
for now. As long as I can show that we are capable of making out own
devices and platforms I will have proven what I want to.

If there is anything I can do to help let me know.

Cheers,
Troy

Hi Troy,

Unfortunately, there is at the moment a significant lag between Shep's
new HDL work and the main OpenCPI repository.  This is mostly due to a
batch of platform work on things like FMC150 and USRP N210, that will be
integrated when they are done in a month or two.
We do not have a commitment for full FMC150 support in the short term,
but as you can see we have done some of it already.

Will will probably do a partial sync-up sooner than that (in May) in
order to bring a few small improvements forward, and probably the
ethernet control plane (which will work on the
ML605 and N210 at least).

For your purpose, if you have to now, working with the current OpenCPI
repo is probably best.

We definitely have plans for what we call "container automation".
That is, auto-generating the layer between the application and the
platform, including the optional inclusion of the "device workers" and
"interconnect workers".  Right now the HDL modularity for this isn't
quite right for this purpose.
There are a few half-way steps that would make the mkFTop problem easier
by moving some logic down the hierarchy.
I'll see if we can do that sooner than later, but we are once again on a
"sprint" through the (our) summer that won't allow for real container
automation to happen until later this year.

Interestingly enough we have recently been asked to make the "platform
support" process more regular and documented.
Probably after the USRP N210 we will be ready to do that.
