cpuidle_idle_call(9)

🌸 NAME 🌸

okay so bestie, this is cpuidle_idle_call(9) from the Kernel API Manual, and she is literally the main idle function. no cap, that's the whole name section. 💅

✨ SYNOPSIS ✨

void cpuidle_idle_call (bool stop_tick );

🎀 ARGUMENTS 🎀

• stop_tick — ngl the original says -- undescribed --, so there is literally no description for this one. not me staring at a blank field 😭💀

💅 NOTE 💅

okay so huge vibe check: no locks or semaphores should be used here. periodt. 🔒🚫

On architectures that support TIF_POLLING_NRFLAG, it is called with polling set, and it returns with polling set. If it ever stops polling, it must clear the polling bit. like, that part is not optional, bestie. ✨
