Okay so welcome to the Kernel API Manual, bestie — this page is literally all about getting the current powerdomain power state, and it’s giving main character energy ngl ✨

🌸 NAME 🌸

pwrdm_read_pwrst — get current powerdomain power state 🫶

---

🎀 SYNOPSIS 🎀

int pwrdm_read_pwrst (struct powerdomain *pwrdm );

---

🦋 ARGUMENTS 🦋

• pwrdm — the struct powerdomain * to get power state, periodt 💅

---

✨ DESCRIPTION ✨

So this one returns the current power state of the powerdomain pwrdm, and that’s the whole vibe check 🔥

It returns -EINVAL if the powerdomain pointer is null, or it returns the current power state upon success. Lowkey important: if the power domain only supports the ON state, then it just returns ON as the current state. No cap 🧚
