Without a miop module, nodectl list from the BMC fails and the high-speed network between Blade 3s in a Cluster Box is lost.
Additionally, Ubuntu 25.04 LTS is due soon and I notice that the Ubuntu image made available with miop modules included is built with a 4k page-size: increasing this to 16k or 64k could lead to ~15% increases in performance (see this article - and note that the vendor kernels for Raspberry Pi 4 & 5 are now using a 16k page-size for performance reasons), so a lot of potential is being squandered here.
Please consider making the source to the miop driver available - even if under NDA or similar - so that developers can build their own custom kernels whilst retaining this key functionality.
