💅 acpi_get_gen..._coordinates(9) 💅

✨ NAME ✨

acpi_get_genport_coordinates — retrieve the access coordinates for a generic port 🌸

---

🎀 SYNOPSIS 🎀

int acpi_get_genport_coordinates(u32 uid, struct access_coordinate *coord);

---

🦋 ARGUMENTS 🦋

• uid — the ACPI unique id. it's the little name tag that tells you which thing we're talking about 🏷️
• coord — the access coordinates get written back out for the generic port. heads up: expect a 2 levels array, no cap, that's just how it is 💅

ngl bestie, the description here is short and sweet — but that's literally all there is, so we're not gonna invent extra lore. facts only, always 💖

and that's the whole page, mwah 💋 — this one came from ./drivers/acpi/numa, dated October 2026, and yeah the header and footer up top and down there are the same thing, iconic of them tbh 🧚💜
