💖 libnvme(2) — okay bestie, let's talk about struct nvme_channel_config_desc 💖

This one lives in the libnvme manual, section 2, and it's genuinely one of those little structs that's doing the most with the least. It's giving quiet main character energy. Let's get into it 🦋

✨ NAME ✨

struct nvme_channel_config_desc — Channel Configuration Descriptor

Yes bestie, that's literally the whole name. Short. Iconic. To the point. 💅

---

🌸 SYNOPSIS 🌸

Here's the whole glow-up, verbatim, no edits, no notes:

struct nvme_channel_config_desc {
    __le16 chanid;
    __le16 chmus;
    struct nvme_media_unit_config_desc mu_config_desc[];
 };

Okay so the way this works: two lil __le16 values up top, and then a flexible array member at the end that just keeps going as long as it needs to. It's the "there's always room for one more" of struct design. Obsessed. 🫶

🎀 Members 🎀

• chanid — the Channel Identifier. That's it, that's the whole job. It tells you which channel you're looking at. Lowkey essential, highkey underrated. ⭐
• chmus — the Number Channel Media Units</> count. Basically "how many media units are we rolling with in this channel". The math girlies are thriving. 🔥
• mu_config_desc — the Channel Unit config descriptors, and it's a flexible array, so it's not a fixed little thing — it's however many descriptors the channel actually needs. See struct nvme_media_unit_config_desc for the deets, because that's a whole separate struct with its own whole separate lore. 📚

ngl, if you're looking at mu_config_desc and thinking "wait, where does this array end?" — that's a chmus situation, bestie. The count is right there. Use it. 🙈

🧚 quick vibe check

Two __le16s and a flexible array. That's the whole struct. No cap.

• <red>__le16</red> means little-endian 16-bit, so don't go reading these like they're your native-endian lil ints unless you actually know what you're doing. 💀
• The array at the end is flexible — it's not a pointer, it's inline trailing storage. If that sentence made your brain short-circuit, that's normal, take a sip of water. 🍓

🌈 SEE ALSO 🌈

No SEE ALSO section here, bestie — but the page does point you at struct nvme_media_unit_config_desc for the descriptor details, so go say hi to that one next. 👑

<anything>That's the whole page, fr fr. It's short, it's sweet, it's the Channel Configuration Descriptor, and it ate. ✨
