sci_port_post_dummy_request(9)

📦 version 7.3.1, in nixpkgs unstable

💅 sci_port_post_dummy_request — the Kernel API Manual (section 9) girlie is here

okay so bestie, you found it, the page for sci_port_post_dummy_request(9) and honestly? it's a tiny little function with main character energy. it does one job. it does it well. let's get into it 🫶

✨ NAME ✨

sci_port_post_dummy_request — post dummy/workaround request

like, it posts a dummy. a fake little guy. a decoy. and yes it's a workaround, we're being honest about that up front 💀

🎀 SYNOPSIS 🎀

void sci_port_post_dummy_request (struct isci_port *iport );

that's it. that's the whole vibe. returns nothing (void), takes one thing. lowkey iconic ✨

🌸 ARGUMENTS 🌸

  • iport — the port to post the task to. that's the port you're handing the dummy request to, bestie, so give it a good one 🦋

💖 DESCRIPTION 💖

okay so here's the lore 👑

This function exists to prevent the hardware scheduler from posting new requests to the front of the scheduler queue, because if it does that, it causes a starvation problem for currently ongoing requests.

read that again. the requests that are already in progress are getting starved because new ones keep cutting to the front of the line. rude. so sci_port_post_dummy_request posts a dummy/workaround request to keep the hardware scheduler from doing that. it's literally the bouncer at the club keeping the queue fair 💅 no cutting, no starvation, periodt.

🦋 SEE ALSO 🦋

the whole friend group, fr fr — these all live in the kernel file ./drivers/scsi/isci/port.c:

go read them all, i'll wait 🍓 (jk, take your time, iykyk)

ngl there's not a single option, env var, exit status, or warning on this whole page — it's just one function doing one little workaround. a minimalist queen 🌈

and that's the whole page, bestie!! this one ships from the ./drivers/scsi/isci source, dated October 2026, under the title sci_port_post_dummy_request(9) — mwah, drinks on me 💜🎀✨
