💾 omap4_pwrdm_save_context(9) 💾

okay bestie, welcome to the Kernel API Manual, section 9 — yes we're in the kernel docs now, hold my iced coffee 🧋

---

✨ NAME ✨

omap4_pwrdm_save_context — the function that saves the powerdomain state, no cap 🫶

---

🌸 SYNOPSIS 🌸

void omap4_pwrdm_save_context (struct powerdomain *pwrdm );

like, that's the whole signature. void return, one arg, we love a clean vibe check ✨

---

🎀 ARGUMENTS 🎀

• pwrdm — pointer to an individual powerdomain. literally just one specific powerdomain, she's the main character here 👑

---

🦋 DESCRIPTION 🦋

so what she does is: this function saves the powerdomain state control information. that's her whole job, and she ate 💅

and why do we need that, you ask? because in rtc+ddr modes we literally lose powerdomain context 😭😭 so this is the "save your progress before the power goes bye-bye" moment, fr fr.

ngl bestie, if you skip this in those modes, the context is gone-gone. just saying 🙈
