💅 pm_generic_runtime_suspend(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a lil function that lives rent-free in the power-management corner of the kernel, and honestly? She's simple, she's clean, she does exactly one thing. main character energy fr fr 🎀

🌸 NAME 🌸

pm_generic_runtime_suspend — the generic runtime suspend callback for subsystems, no cap 🫶

⭐ SYNOPSIS ⭐

int pm_generic_runtime_suspend (struct device *dev );

literally that's the whole signature. short, sweet, slay 💅

🦋 ARGUMENTS 🦋

  • dev — the device we're suspending. that's her. that's the one. the device to suspend 🫡

✨ DESCRIPTION ✨

okay so here's the vibe check 👑 — if PM operations are defined for the dev's driver, and those operations include ->runtime_suspend, then this function executes it and returns its error code. periodt.

otherwise? it just returns 0. that's it. no drama, no notes, iconic behaviour honestly 🧚

ngl the whole thing is basically "if the driver has a ->runtime_suspend, run it and pass along whatever it says; if not, shrug and return 0." lowkey the most chill function in the file 😭💖
