It was a GSoC project, there are patches on phabricator, they just need a review. RHEL has support for ppc64le, so we can add support to ports as well (but not for ppc64, unfortunately, it can be supported in the kernel, but but without support in ports). 3. drm-kmod would be very handy on desktops. I finally aquired another POWER9 system that is a replacement for my amd64 server, running my own services, so I can finally say I'm dogfooding FreeBSD on POWER, but the desktop is still on Linux. 4. Loader support. I've already mentioned it to Timothy, can also mention it here: there's no support at all for loader on PowerNV. We just load the kernel directly. To have ZFS on /, we need a custom kernel. It would be best to have a 2nd stage loader (loaded from Petitboot) that would load the kernel and required modules.
