panthor_pwr_...in_force_off(9)

💅 panthor_pwr_domain_force_off — NAME ✨

okay so this is a page straight out of the Kernel API Manual, and the function is panthor_pwr_domain_force_off — bestie, it does exactly what it says on the tin: it forcefully powers down a domain. no negotiating, no "please", we're just cutting the lights 🔥

---

🎀 SYNOPSIS 🎀

int panthor_pwr_domain_force_off (struct panthor_device *ptdev , u32 domain );

like, you hand it a device and a domain, and it goes yeet at the power supply ⚡

---

🌸 ARGUMENTS 🌸

• ptdev — the device, bestie. that's the thing you're working with 🫶
• domain — the domain you want to forcefully power down. yes, forcefully. it's right there in the name 💅

---

💖 DESCRIPTION 💖

so here's the vibe check: this function will attempt to retract and power off the requested power domain. two steps, one dream ✨

but — and this is the important part, no cap 🙈 — if retraction fails, the operation is aborted. like, we don't even get to the power-off era. it's giving "we tried and we stopped".

and if power off fails? the domain will remain retracted and under the host control. so it's not fully off, it's just... parked. sitting there. in host-controlled limbo 💀

---

🌈 RETURN 🌈

0 on success, or a negative error code on failure. that's the whole story, periodt 👑
