💅 isci_remote_device_not_ready — Kernel API Manual

okay so this is a page from the Kernel API Manual, and honestly? it's a tiny little function with main character energy. it's called isci_remote_device_not_ready and it lives in the kernel, bestie. let's get into it 🎀

✨ NAME ✨

isci_remote_device_not_ready — this is the function that gets called by the ihost when the remote device is not ready. yeah, the name is giving exactly what it says on the tin 💀

so what does it actually do? it marks the isci device as ready — and no, not "ready_for_io", just plain old ready, okay? read the quotes carefully, they matter — and then it signals the waiting proccess. that's it. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

void isci_remote_device_not_ready (struct isci_host *ihost ,
                                   struct isci_remote_device *idev ,
                                   u32 reason );

like… look at her. void. she returns nothing. she doesn't need to. she just does the thing and leaves. 👑

💖 ARGUMENTS 💖

  • ihost — this parameter specifies the isci host object. it's the host, babes. the big one. the home base 🏠
  • idev — this parameter specifies the remote device. the device in question. the one that's being all not-ready rn 🙈
  • reason — reason to switch on. literally that's the description. a u32 holding the reason you switch on. iykyk 🔥

🧚 DESCRIPTION 🧚

okay this is the important bit, pay attention:

sci_lock is held on entrance to this function.

so like… when you walk in the door, sci_lock is already held. it's not your job to grab it, it's already grabbed. do not touch. do not release. just vibe with the lock already in your hand, fr fr 💅

⭐ SEE ALSO ⭐

peep the kernel file for this one, plus her whole friend group:

that's the whole squad. construct, start, ready, not_ready, stop, gone, found — she's got lore for every stage of the device lifecycle and honestly? obsessed 🌈

and that's the page, bestie!! 🫶 source is ./drivers/scsi/isci, dated October 2026, and the page you just read is isci_remote_...ce_not_ready(9) — go forth and signal your waiting proccesses 💜✨
