rpmh_regula...optimum_mode(9)

✨ rpmh_regulator_vrm_get_optimum_mode 💅

okay so bestie, this is a page straight outta the Kernel API Manual 📖 — yes, that Kernel API Manual, the one with all the driver internals — and it's about one very specific little function. her full name is rpmh_regulator_vrm_get_optimum_mode (a mouthful, i know, she ate tho 💅) and in the header it gets shortened to rpmh_regula...optimum_mode(9) because even manpages gotta truncate for the vibes. anyway. let's get into it 🫶

🌸 NAME 🌸

rpmh_regulator_vrm_get_optimum_mode — literally just get the mode based on the load ✨ that's her whole job, that's the entire assignment, and she does it flawlessly 💖

---

🦋 SYNOPSIS 🦋

unsigned int rpmh_regulator_vrm_get_optimum_mode (struct regulator_dev
*rdev , int input_uV , int output_uV , int load_uA );

so yeah. she takes a struct regulator_dev * and three whole ints, and she hands you back an unsigned int. no cap, that's the signature, copy it exactly, i don't make the rules 🎀

---

🎀 ARGUMENTS 🎀

• rdev — the regulator device pointer for the rpmh-regulator 👑 like, the actual device we're talking about here. main character energy fr.
• input_uV — input voltage. yes bestie, in microvolts 🌈
• output_uV — output voltage. also volts-ish, also µV-coded 💜
• load_uA — the aggregated load current, measured in microamps ⚡ note the word aggregated, she's not out here guessing, this is the combined number iykyk

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function is used in the regulator_ops for VRM type RPMh regulator devices. that's it. that's the whole description. she's a supporting cast member in the regulator_ops situation and she's thriving 🌟

ngl it's giving "short but essential" and honestly? iconic. no further notes 🧚

---

🔥 RETURN 🔥

• 0 on success 🎉
• a negative error number on failure 😭 (that's your standard kernel "something went wrong" vibe check, so watch for that negative, bestie)

👑 SEE ALSO 👑

go check these out, they're all in the same little friend group 🫶:

• Kernel file ./drivers/regulator/qcom-rpmh-regulator.c 📁 (yes, the whole file, go read her)
• enum rpmh_regulator_type(9)
• enum regulator_hw_type(9)
• struct rpmh_vreg_hw_data(9)
• struct rpmh_vreg(9)
• struct rpmh_vreg_init_data(9)
• rpmh_regulator_send_request(9)
• rpmh_regulator_init_vreg(9)

like, the whole rpmh regulator cinematic universe tbh 🌈⭐

💀 and remember pookie — this is kernel API documentation, so the return value is real and the negative error number will absolutely find you if you ignore it. no cap.

🌸 that's the page!! it lives under ./drivers/regulator (that's the source/version situation 🫶) and it's dated October 2026 — so she's a future icon, literally ahead of her time 💅✨ mwah, go ship some regulators bestie 🎀
