Hi Pierrick,
Here's what I need to run our RME test with FEAT_GCS enabled,
based on your
https://github.com/pbo-linaro/qemu-linux-stack rme_release
If your can run what's needed to update the functional artifacts,
I can re-spin my FEAT_GCS series with that included.
Thanks,
r~

There appears to be no tagged release with FEAT_S1PIE, but
it is upstream. As is the PMU patch we were carrying.

I didn't find the PMU patch upstream, so keeping it locally.

Thanks for the patches Richard.
You can update concerned QEMU tests with attached patch using new artifacts.
Let me know if everything works on your side.
