libnvme(9)

🎀 libnvme(9) — the enum nvme_cmbmsc page, bestie edition 🎀

okay so this is a page straight out of the libnvme manual (that's the manual name, iykyk), and honestly? it's a little one. but we're gonna treat it with the respect it deserves because it's about controller memory buffer memory space control and that's kind of a big deal 💅

---

✨ NAME ✨

enum nvme_cmbmsc — literally this field indicates the controller memory buffer memory space control. that's the whole vibe. no cap. 🦋

---

✨ SYNOPSIS ✨

here's the whole enum, copy-paste ready, don't touch anything:

enum nvme_cmbmsc {
    NVME_CMBMSC_CRE_SHIFT ,
    NVME_CMBMSC_CMSE_SHIFT ,
    NVME_CMBMSC_CBA_SHIFT ,
    NVME_CMBMSC_CRE_MASK ,
    NVME_CMBMSC_CMSE_MASK

};

like, that's it. five constants. short and iconic 👑

---

✨ Constants ✨

okay so each one of these does exactly one thing and we're gonna learn them together 🫶

• NVME_CMBMSC_CRE_SHIFT — the shift amount to get the capabilities registers enabled. that's the whole job. slay 💖
• NVME_CMBMSC_CMSE_SHIFT — the shift amount to get the controller memory space enable. shifts, but make it memory space ✨
• NVME_CMBMSC_CBA_SHIFT — the shift amount to get the controller base address. base address, but shifted. periodt 🌸
• NVME_CMBMSC_CRE_MASK — the mask to get the capabilities registers enabled. masking is self-care, ngl 🎀
• NVME_CMBMSC_CMSE_MASK — the mask to get the controller memory space enable. last one, and yes it ate 💅

real talk: there are no options, no exit statuses, no environment variables, no warnings and no SEE ALSO on this page — it's just the enum and its five constants, and we are not gonna pretend otherwise. keep it honest bestie 🔥
