Hi Benoit,
good to see you're still around.

Thanks for mentioning this. I forgot it exists, since it was still on
the old mailing list.

Could you run your tests against the simple implementation that I posted
a while ago (https://patchwork.kernel.org/cover/11049365/) and provide
your feedback? Since it is already based on the current tpm_tis_core, it
is probably easier to integrate necessary changes there.
By the way, has it gotten any easier in the meantime to get hold of your
TPMs to use them for kernel tests?
Alexander
