[Openpvrsgx-devgroup] Current Status linux_openpvrsgx

[Philipp Rossak]

Hey Nikolaus,

Thanks for the infos!

I had a more detailed look into the sources today and I'm very optimistic
to get the sunxi devices (A83T and A31) working with DDK 1.17.

Can you direct me to the user space blobs, that you are using? I found that
many, that I'm not really sure which to choose.
Maybe we should also create a repo for these so we have them all at one
place.

Sorry! I just missed that Jeroen wants to be added to the project. That
mail got somehow lost in my emails. I added him today to the repo.
(@Nikolaus I gave you also admin permissions, so you can also do this in
the future)

Cheers
Philipp

Now Replying all
