_clkdm_del_sleepdep(9)

💅 _clkdm_del_sleepdep(9) — Kernel API Manual ✨

okay so bestie, welcome to the kernel API manual for _clkdm_del_sleepdep. yes it's a (9) page, yes it's nobody's main character, but it's our main character today 🫶

---

🌸 NAME 🌸

_clkdm_del_sleepdep — remove a sleep dep from clkdm2 to clkdm1 (lockless) 💫

---

🎀 SYNOPSIS 🎀

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

---

⭐ ARGUMENTS ⭐

• clkdm1 — the dependent one, the *struct clockdomain ** you're literally un-blocking from sleeping. free her 🦋
• clkdm2 — the source, the *struct clockdomain ** that has to be active for the dependency to even exist in the first place 👑

---

💖 DESCRIPTION 💖

the whole vibe: you're letting clkdm1 auto-go-inactive — and then after that, on to retention or off — independent of whatever clkdm2's activity state is doing. no more looking at clkdm2 for permission, she's free ✨

returns, and this part matters so read it twice:

• -EINVAL if you hand it invalid clockdomain pointers, or if you call it on a machine that doesn't support software-configurable hardware sleep dependencies 😭 no cap, that machine just can't do the thing
• -ENOENT if the dependency you specified cannot be cleared in hardware 💀
• 0 upon success — slay, icon behavior 👑
