NDCTL-ENABLE-REGION(1)

✨ NAME ✨

ndctl-enable-region — bestie, this turns on the region(s) you point at and every single descendant namespace that comes with them 💖

---

🌸 SYNOPSIS 🌸

ndctl enable-region <region> [<options>]

---

🦋 DESCRIPTION 🦋

okay so picture this: for every PMEM range / interleave-set out there, a generic REGION device gets registered, right? and LIBNVDIMM ships a built-in driver specifically for those REGION devices 👑

and what does that driver actually do, you ask? it's the one in charge of parsing the namespace labels, and then instantiating PMEM namespaces for each coherent set of labels. that's the whole job. it's giving label-parser main character energy and honestly? we love that for it 💅

---

🎀 OPTIONS 🎀

• <region> — a regionX device name, or a region id number. use it to restrict the operation to the specified region(s). you can pass the keyword all to say "no restrictions, idc", but heads up: that's literally the same as just not passing a --region option at all 🙈
• -b, --bus= — a bus id number, or a provider string (like "ACPI.NFIT"). use it to restrict the operation to the specified bus(es). and yeah, you can pass the keyword all here to indicate the lack of any restriction, but ngl that's the exact same thing as not supplying a --bus option at all 💀
