✨ ab8500_fg_calculate_scaled_capacity(9) ✨

okay so real talk, bestie — this is a page from the Kernel API Manual, and today's main character is ab8500_fg_calculate_scaled_capacity. it's giving "small function, big job" energy, and honestly? we're obsessed 💅

🌸 NAME 🌸

ab8500_fg_calculate_scaled_capacity — the capacity-scaling girlie of the ab8500 fuel gauge. that's it, that's the vibe. lowkey her whole personality is "make the numbers look right for the people upstairs." 🎀

🦋 SYNOPSIS 🦋

int ab8500_fg_calculate_scaled_capacity (struct ab8500_fg *di );

like, she takes one pointer and hands you back an int. clean, simple, iconic. no cap. ✨

💖 ARGUMENTS 💖

  • di — a pointer to the ab8500_fg structure. that's the fuel-gauge bestie herself, the whole struct, the main character. she needs it, so hand it over 🫶

👑 DESCRIPTION 👑

so here's the tea, and it's actually important tea ☕ — ab8500_fg_calculate_scaled_capacity calculates the capacity that gets shown to the upper layers. like, the stuff that people (and by people i mean the rest of the kernel and eventually your little battery icon) actually see.

and the way it does that? it scales the capacity so that 100% is the reference — pulled from the actual capacity at the moment the charger gets removed, when charging is hanging out in maintenance mode. yeah. that exact moment. that's the moment she cares about. ⚡

so: charger out, maintenance mode, actual capacity in hand → boom, now that's your 100% reference, and everything else gets scaled around it. periodt. 💀🔥

🌈 SEE ALSO 🌈

okay this is the part where the page just. keeps. going. it's a whole group chat of related symbols and honestly? i respect the commitment 💜. the kernel file lives at ./drivers/power/supply/ab8500_fg.c and the struct squad rolls deep:

iykyk — if you're poking at the ab8500 fuel gauge, you're gonna meet all of these eventually 🧚

fr fr, don't skip the DESCRIPTION — the whole "100% reference from the actual capacity on charger removal in maintenance mode" thing is the entire point of this function. miss it and the scaling will confuse you, no cap 😭

and that's the page!! this lil slice of kernel-api goodness is served up from ./drivers/power/supply, dated October 2026, and it's literally the ab8500 fuel gauge's finest hour. go forth, scale that capacity, and slay 💖⭐🎀
