💅 libnvme(9) — enum nvme_mi_config_smbus_freq 💅

okay so bestie, welcome to the libnvme manual, section 9, and today's main character is an enum called nvme_mi_config_smbus_freq. that's a whole mouthful, i know, but it's literally just a little menu of SMBus/I2C frequencies, and honestly? she ate. 🦋

🌸 NAME 🌸

enum nvme_mi_config_smbus_freq — the SMBus/I2C frequency values, i.e. the speed picks, i.e. the vibe check for your bus clock ✨

---

🎀 SYNOPSIS 🎀

here's the whole fam, look at them:

enum nvme_mi_config_smbus_freq {
    NVME_MI_CONFIG_SMBUS_FREQ_100kHz ,
    NVME_MI_CONFIG_SMBUS_FREQ_400kHz ,
    NVME_MI_CONFIG_SMBUS_FREQ_1MHz

};

no cap, that's the entire structure. three constants, zero drama. 👑

---

💖 Constants 💖

okay so these are the actual values, and yes there are exactly three, and yes i'm listing all three because we do not skip:

• NVME_MI_CONFIG_SMBUS_FREQ_100kHz — literally 100kHz. the chill, slow-and-steady one. 🐢
• NVME_MI_CONFIG_SMBUS_FREQ_400kHz — that's 400kHz, the middle child, the balanced icon. 🌈
• NVME_MI_CONFIG_SMBUS_FREQ_1MHz — 1MHz bestie. main character energy, maximum zoom. 🔥

---

🧚 Description 🧚

so what are these even for? these are the values used in the SMBus Frequency device configuration. that's it, that's the whole assignment. 💅

when you wanna peek at the current setting, go see libnvme_mi_mi_config_get_smbus_freq — she's the getter, she reads the tea. and when you wanna change it up, that's libnvme_mi_mi_config_set_smbus_freq, the setter, the one who actually does something about it. 🫶

iykyk: these constants only make sense paired with those two config calls — don't just scatter them around and hope for the best, bestie. 🙈

and that's the whole page!! short, sweet, three frequencies and a dream. 💜

sign-off time, because the fine print deserves love too: this little love letter is the enum nvme_mi_config_smbus_freq page, dated October 2026, and it lives in the libnvme(9) API Manual. mwah. 😘🎀🌸
