binder_wakeu...read_ilocked(9)

💖 binder_wakeup_thread_ilocked(9) — the Kernel API Manual ✨

okay bestie, so we're in the <pink>Kernel API Manual</pink> today and the star of the show is binder_wakeup_thread_ilocked 💅 (the header truncates it all cute as binder_wakeu...read_ilocked(9) but you and me both know the real name, iykyk). let's get into it 🫶

---

🌸 NAME 🌸

binder_wakeup_thread_ilocked — wakes up a thread for doing proc work. that's the whole vibe fr fr 😌

---

🦋 SYNOPSIS 🦋

void binder_wakeup_thread_ilocked (struct binder_proc *proc , struct
       binder_thread *thread , bool sync );

yes she takes three args, yes she returns nothing (void queen, no notes) 👑

---

🎀 ARGUMENTS 🎀

• proc — the process you wanna wake a thread up in. like, which house are we knocking on 🏠
• thread — the specific thread to wake up, and lowkey it may be NULL 🙈
• sync — a bool that says whether this wake-up is gonna be a synchronous one ⚡

---

💜 DESCRIPTION 💜

so this function wakes up a thread inside the proc process. the caller is allowed to hand over a specific thread to wake via the thread parameter — main character energy, very targeted 💅

but if thread is NULL? no problem bestie, she'll wake up the threads that have called poll 🫶

💀 real talk though: for this to actually work the way you expect, the caller should first call binder_select_thread to find a thread to handle the work (assuming they don't already have one in hand), and then pass that result straight into the thread parameter. skip that step and it's giving chaos, no cap 😭
