ab8500_char...vbus_in_curr(9)

💖 ab8500_char...vbus_in_curr(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual page for ab8500_char...vbus_in_curr(9). yes that name is a whole mouthful, and yes the truncation with the ... is giving "my crush's contact name got cut off in my phone" energy 😭 but we move. this is a Linux kernel function, it lives in ./drivers/power/supply, and it's about telling your charger how much juice it's allowed to slurp from USB. let's get into it 🫶

✨ NAME ✨

ab8500_charger_set_vbus_in_curr — set VBUS input current limit 💅

like... it literally does what it says on the tin. no cap, this one's an icon.

---

🌸 SYNOPSIS 🌸

int ab8500_charger_set_vbus_in_curr (struct ab8500_charger *di , int
ich_in_ua );

that's the whole signature, copied exactly, don't come for me 🎀

---

🦋 ARGUMENTS 🦋

• di — pointer to the ab8500_charger structure. it's the main character of this whole file, so bestie you're gonna be handing it around a lot ✨
• ich_in_ua — the charger input current limit, in microampere. yes, micro. that's the unit. respect it 🙈

---

💜 DESCRIPTION 💜

so what does it actually do? it sets the current that can be drawn from the USB host ⚡ basically it's the bouncer at the club deciding how many amps get through the velvet rope, and the USB host is standing outside like "let me in" 💀

and if things go sideways? it returns an error code in case of failure. but else? 0 (on success) 🎉 so like, zero means we slayed. remember that, iykyk.

and that's a wrap bestie!! 🎀 this page is from ./drivers/power/supply, dated October 2026, and it's the ab8500_char...vbus_in_curr(9) entry of the Kernel API Manual. go set some current limits, stay hydrated, and remember: 0 means success 💖✨🦋
