I got a hint from github user "mirh" that there is also an Intel GMA driver with newer
Linux support:


It turned out to be an older DDK (1.5) but with fixes applied up to ca. v4.0.

I have added it as well to our collection (should we call it a "museum"???).

So we have now a mix of DDK 1.5 up to DDK 1.17 and kernel support v3.7 up to v5.10...

IMHO this should already be enough material if someone is interested in studying
the architecture of the DDK and kernel driver on different SGX releases, different
SoC and different kernels.

Maybe a bachelor or master thesis?

There is also a full tree now which should include our CedarView and Poulsbo
