💅 qcom_labibb_sc_recovery_worker(9) 💅

ok so bestie, welcome to the Kernel API Manual, section 9 — this page is literally called qcom_labibb_sc_recovery_worker and it's here to explain one very specific little worker function. it's giving niche but iconic, iykyk ✨

🌸 NAME 🌸

qcom_labibb_sc_recovery_worker — handle the Short Circuit event 🩹⚡

like, that's the whole job. short circuit happens, this worker shows up. periodt.

🦋 SYNOPSIS 🦋

void qcom_labibb_sc_recovery_worker (struct work_struct *work );

that's it, that's the signature. no cap, it returns nothing and takes one thing 💅

🎀 ARGUMENTS 🎀

  • work — the SC work structure 🫶 this is the work item that got queued up and is now being run, it's the main character of this whole function ngl

✨ DESCRIPTION ✨

okay so here's the lore 🧚:

this is the worker function that handles the Short Circuit Protection hardware event. it's the designated recovery bestie for when the hardware gets messy.

what it does: it checks whether the hardware is still signaling a short-circuit condition. and if that condition is still being signaled after LABIBB_MAX_SC_COUNT times, it will eventually never re-enable the regulator — like, at all. that's the dramatic part 😭 it gives up on purpose, and honestly? valid.

now, two scenarios where this worker just... stops 🌈:

  1. the driver that's consuming the regulator didn't take any action for the SC condition, or
  2. the hardware didn't stabilize

in either case, this worker will stop rescheduling, leaving the regulators disabled — which is already how the Portable Batch System (PBS) left them. so yeah, disabled is the vibe, and this worker isn't about to fight PBS over it 🙈

⚠️ heads up bestie: if the SC condition keeps getting signaled past LABIBB_MAX_SC_COUNT, the regulator stays off forever. this is intentional, not a bug, don't come for me 💀

🔥 RETURN 🔥

  • IRQ_HANDLED — for success ✅ slay
  • IRQ_NONE — for failure 💀 rip

the source file itself, living at:

and its friend group of related functions 🫶:

go read those too, they're all part of the same little regulator squad ✨

and that's the page!! 🎀 sign-off time: this one comes from the ./drivers/regulator source, dated October 2026, and the header/footer both abbreviate the name as qcom_labibb_...overy_worker(9) because apparently even the manpage was too long to fit 😭 iconic honestly. bye bestie, go fix those short circuits 💜🦋
