💜 libnvme — enum nvme_cmbebs

ok so bestie, this page is from the API Manual for libnvme, and it's literally all about one little enum called enum nvme_cmbebs 💅 don't worry, it's way less scary than it sounds.

✨ NAME ✨

enum nvme_cmbebs — this field indicates the controller memory buffer elasticity buffer size 🎀

🌸 SYNOPSIS 🌸

enum nvme_cmbebs {
    NVME_CMBEBS_CMBSZU_SHIFT ,
    NVME_CMBEBS_RBB_SHIFT ,
    NVME_CMBEBS_CMBWBZ_SHIFT ,
    NVME_CMBEBS_CMBSZU_MASK ,
    NVME_CMBEBS_RBB_MASK ,
    NVME_CMBEBS_CMBWBZ_MASK ,
    NVME_CMBEBS_CMBSZU_B ,
    NVME_CMBEBS_CMBSZU_1K ,
    NVME_CMBEBS_CMBSZU_1M ,
    NVME_CMBEBS_CMBSZU_1G

};

🦋 Constants 🌈

okay here's the whole squad, one by one, no gatekeeping 🫶

• NVME_CMBEBS_CMBSZU_SHIFT — the shift amount you use to get the CMB elasticity buffer size units ✨
• NVME_CMBEBS_RBB_SHIFT — the shift amount you use to get the read bypass behavior 👑
• NVME_CMBEBS_CMBWBZ_SHIFT — the shift amount you use to get the CMB elasiticity buffer size base 💫
• NVME_CMBEBS_CMBSZU_MASK — the mask you use to get the CMB elasticity buffer size units 🎀
• NVME_CMBEBS_RBB_MASK — the mask you use to get the read bypass behavior 🔥
• NVME_CMBEBS_CMBWBZ_MASK — the mask you use to get the CMB elasiticity buffer size base 🌸
• NVME_CMBEBS_CMBSZU_B — bytes granularity, like, the teeniest unit 🍓
• NVME_CMBEBS_CMBSZU_1K — 1 KiB granularity ⭐
• NVME_CMBEBS_CMBSZU_1M — 1 MiB granularity 💖
• NVME_CMBEBS_CMBSZU_1G — 1 GiB granularity, big main character energy 👑

heads up bestie: NVME_CMBEBS_CMBWBZ_SHIFT and NVME_CMBEBS_CMBWBZ_MASK describe the size base while the others describe the size units — don't mix them up, iykyk 🙈

and that's the whole page, no cap 💅 this was enum nvme_cmbebs from the libnvme API Manual, dated October 2026 — mwah, go slay your buffer sizes 🧚💜
