timerlat_u_dispatcher(9)

💅 timerlat_u_dispatcher(9) — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel API manual (yes, that manual, the one we all pretend we've read) and you bump into timerlat_u_dispatcher. she's a tiny function with a big job and honestly? she ate. let's get into it 🎀

---

🌸 NAME 🌸

timerlat_u_dispatcher — dispatch one timerlatu/ process per monitored CPU 💖

like, one whole process for every CPU you're watching. no cap. that's her whole personality.

---

✨ SYNOPSIS ✨

void * timerlat_u_dispatcher (void *data );

that's it. that's the whole signature. void * in, void * out, she's giving mysterious and slightly unhinged 🦋

---

🫶 ARGUMENTS 🫶

• data — -- undescribed -- 💀

ngl, the docs literally say -- undescribed --. nobody wrote anything about this one. she's a mystery, she's an enigma, she's an undocumented pointer. respect the privacy tho 🙈

---

🔥 DESCRIPTION 🔥

so this is a thread main — meaning it's the function a thread starts running. and what does she do? she forks one new process for each monitored CPU. every single one. no skipping, no slacking, one process per CPU, periodt 👑

then she just... waits. patient main character energy. 🌈 and she's waiting on one of two things, whichever comes first:

• rtla telling her to kill the child processes 💀
• some child process dying, and then the cleanup of all the processes 🧹

whichever comes first. that's the vibe check. first one to the party wins and she handles it. lowkey elegant if you think about it 💅

heads up bestie: it's whichever comes first — she does not wait for both. don't be out here assuming she'll hang around for round two 😭

mwah, that's a wrap on timerlat_u_dispatcher(9) from ./tools/tracing/rtla/src, dated October 2026. she forked, she waited, she cleaned up, she left. iconic behavior fr fr 💜🌸✨
