💫 panthor_fw_post_reset(9) 💫

okay so bestie, welcome to the Kernel API Manual — this one's panthor_fw_post_reset, and yes she's a function, yes she's in the kernel, and yes she's iconic ✨

---

🌸 NAME 🌸

panthor_fw_post_reset — the one you call after a reset. that's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

int panthor_fw_post_reset (struct panthor_device *ptdev);

---

💜 ARGUMENTS 💜

• ptdev — the device, periodt. that's the whole argument, she's low maintenance 💅

---

🔥 DESCRIPTION 🔥

so basically this kicks off the FW — start her up, let her glow ✨

and here's the tea: if this is not a fast reset, then every single FW section gets reloaded, fr fr — the whole point is making sure we can actually recover from a memory corruption 😭 like yes we're doing a full refresh, no cap, because corrupted memory is not the moment 🫶
