xe_uc_runtime_suspend(9)

💅 xe_uc_runtime_suspend — bestie edition 💅

okay so real talk, this is a page from the Kernel API Manual and it's about one tiny little function that does exactly one tiny little thing. lowkey iconic of it honestly. let's get into it 🫶

---

✨ NAME ✨

xe_uc_runtime_suspend — the "UC runtime suspend" girlie herself. that's it, that's the whole name, and she's serving exactly what the label says 💖

---

🌸 SYNOPSIS 🌸

here's the whole signature, no notes, no cap, copied exactly:

void xe_uc_runtime_suspend (struct xe_uc *uc );

yes bestie, it returns void. she does the thing and she does not report back. main character energy tbh 👑

---

🦋 ARGUMENTS 🦋

• uc — the UC object, that's it, that's the whole parameter. the one (1) thing you gotta hand her 🎀

---

💜 DESCRIPTION 💜

so what does she actually do? runtime suspend all UCs. all of them. every single one. not a vibe check, an actual suspend. periodt ✨

ngl there's not a lot more to say here — the description is literally one line and honestly? she ate. minimalism is a look 💅

---

🌈 SEE ALSO 🌈

if you're the kind of person who falls down a rabbit hole (same), here's the whole friend group:

• Kernel file ./drivers/gpu/drm/xe/xe_uc.c — the source file, the origin story 🧚
• xe_uc_init_post_hwconfig(9) — the "init post hwconfig" bestie
• xe_uc_runtime_resume(9) — her counterpart, the one who wakes everything back up 😭
• xe_uc_declare_wedged(9) — the one you call when things are, uh, not going great 💀

---

🍓 lowkey reminder: void return means no status, no error code, nothing to check. don't go looking for a return value that isn't there bestie, it's giving delulu 🙈

---

alright that's the whole page!! stay hydrated, read your kernel docs, and remember that this little function lives in ./drivers/gpu/drm/xe, dated October 2026, and goes by xe_uc_runtime_suspend(9) 💖✨🎀 bye bestie, ily, go suspend some UCs 🦋🌸
