STRUCT THREAD_GROUP_CPUTIMER(9)

💅 STRUCT_THREAD_GROUP_CPUTIMER(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual (section 9, kernel internals, very main character energy) — and it's about one lil struct that just wants to keep time for your whole thread group. let me walk you through it 🫶

---

✨ NAME ✨

struct thread_group_cputimer — thread group interval timer counts. that's it, that's the whole vibe: it's the thing holding the interval timer numbers for a thread group. 🕰️

---

🌸 SYNOPSIS 🌸

here's the whole struct, bestie, and yes it's literally a one-member situation, we love a minimalist king 👑

struct thread_group_cputimer {
    struct task_cputime_atomic cputime_atomic;
 };

---

🎀 Members 🎀

• cputime_atomic — the atomic thread group interval timers. atomic, meaning nobody's out here catching it mid-update, fr fr. ⚛️✨

---

🦋 Description 🦋

so what is this thing? it's the struct that contains the version of task_cputime, above, that is used for thread group CPU timer calculations. like, task_cputime has a cousin and this is it, and its whole job is being the one the thread group CPU timer math reaches for. no cap, that's the entire description. 🌈

---

⭐ SEE ALSO ⭐

• Kernel file ./include/linux/sched/signal.h — go read it, iykyk 💖
• set_restore_sigmask(9) — another page, another adventure 🧚

---

ngl the "above" in the description is doing a lot of heavy lifting here — it's pointing at task_cputime from earlier in whatever doc you're reading this in, so don't come for me if you landed here cold 🙈

---

and that's a wrap, bestie!! this page came to you from ./include/linux/sched, dated October 2026, and it's filed under struct threa...oup_cputimer(9) because apparently even the header had to be abbreviated. slay, stay atomic, and don't forget to man 9 responsibly 💜🎀🔥
