_base_wait_for_doorbell_int(9)

📦 version 7.3.1, in nixpkgs unstable

💖 _base_wait_for_doorbell_int — a Kernel API Manual moment 💖

okay so bestie, welcome to the _base_wait_for_doorbell_int(9) page from the Kernel API Manual, and no cap, this one is a little baddie: it's the function that just sits there and waits for the controller to interrupt us, and that interrupt only ever shows up because somebody wrote to the doorbell. like, ring the bell, get an interrupt. it's giving "ding dong, the IOC is home." 🔔✨

🌸 NAME 🌸

_base_wait_for_doorbell_int — waiting for controller interrupt (generated by a write to the doorbell). that's the whole vibe, fr fr. 💅

🎀 SYNOPSIS 🎀

int _base_wait_for_doorbell_int (struct MPT3SAS_ADAPTER *ioc , int timeout );

like, copy that exactly, don't @ me, it's literally the signature 👑

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object, aka the whole adapter's little world in one struct 🫶
  • timeout — the timeout, and bestie it's measured in seconds ⏳

⭐ RETURN ⭐

  • 0 when it's a success — slay 💖
  • non-zero when it's a failure — not slay, but at least it tells you 😭

💀 NOTES 💀

  • MPI2_HIS_IOC2SYS_DB_STATUS — this bad boy gets set to one when the IOC writes to the doorbell. that's the whole tell, iykyk 🔥

🌈 SEE ALSO 🌈

okay so this list is long, but we do not skip. we never skip. every single one of these is here, exactly as it was, in the same order, because I am a responsible icon and you deserve the full set 🧚💜

yeah. that's all of them. every last one. we ate and left no crumbs 🍓

and that's the page, bestie!! 💖 this little cutie lives over in ./drivers/scsi/mpt3sas, and the docs are dated October 2026 — so like, future icon behavior honestly. mwah, go ring that doorbell 🎀🔔👑
