pwrdm_read_logic_retst(9)

💖 pwrdm_read_logic_retst(9) 💖

okay so this is straight out of the Kernel API Manual, and it's giving “niche OMAP powerdomain lore” in the best way. bestie, we're reading a logic power state. let's get into it 🫶

---

✨ NAME ✨

pwrdm_read_logic_retst — get next powerdomain logic power state

---

🌸 SYNOPSIS 🌸

int pwrdm_read_logic_retst (struct powerdomain *pwrdm );

---

🎀 ARGUMENTS 🎀

• pwrdm — the struct powerdomain * you're using to get the next logic power state 👑

---

🦋 DESCRIPTION 🦋

bestie, this returns the logic power state of the powerdomain pwrdm. if the powerdomain pointer is null, it returns -EINVAL 😭. on success, it returns the next logic power state. that's the whole vibe, no cap ✨

lowkey important: -EINVAL is the null-pointer outcome, and success gives you the next logic power state. that's it 💅
