💅 buffer_icap_reset(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual, page buffer_icap_reset(9). this is like a tiny little manpage, but it's iconic and it does exactly one thing and honestly? respect. 🎀

✨ NAME ✨

buffer_icap_reset — reset the logic of the icap device. literally its whole personality. 🦋

---

🌸 SYNOPSIS 🌸

void buffer_icap_reset (struct hwicap_drvdata *drvdata );

no return value, no drama, just vibes and a reset. periodt.

---

🫶 ARGUMENTS 🫶

• drvdata — a pointer to the drvdata. that's it, that's the whole argument. she's a pointer, she points at the drvdata, we love her. 💖

---

👑 DESCRIPTION 👑

so here's the tea, bestie: writing to the status register resets the ICAP logic in an internal version of the core. that's the move. that's what we're doing here. 🔥

and for the version of the core published in EDK? it's a noop. nothing happens. she's doing nothing and she's doing it beautifully. no cap. 💀
