_clkdm_add_sleepdep(9) 🦋

okay so welcome to this Kernel API Manual page, bestie. We’re talking about _clkdm_add_sleepdep, and the name is literally the whole plot: add a sleep dependency from clkdm2 to clkdm1, and it’s lockless. slay.

🌸 NAME 🌸

_clkdm_add_sleepdep — add a sleep dependency from clkdm2 to clkdm1 (lockless). no cap, that’s the vibe.

✨ SYNOPSIS ✨

int _clkdm_add_sleepdep (struct clockdomain *clkdm1 , struct clockdomain *clkdm2 );

🎀 ARGUMENTS 🎀

  • clkdm1 — the dependent struct clockdomain *, aka “prevent this struct clockdomain * from sleeping.” You’re putting it on do-not-nap duty, fr fr.
  • clkdm2 — the source struct clockdomain *, aka “when this struct clockdomain * is active.” That’s the condition, bestie.

💅 DESCRIPTION 💅

okay so here’s the tea: you’re preventing clkdm1 from automatically going inactive — and then, lowkey, heading to retention or off — if clkdm2 is active. That’s the sleep dependency. ✨

Return tea ☕:

  • -EINVAL — if presented with invalid clockdomain pointers, or called on a machine that does not support software-configurable hardware sleep dependencies.
  • -ENOENT — if the specified dependency cannot be set in hardware.
  • 0 — upon success.
