💖 heci_hcsr_set(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for heci_hcsr_set — no cap, it's a tiny one but she's iconic 🎀

---

✨ NAME ✨

heci_hcsr_set — writes H_CSR register to the heci device 🦋

---

🌸 SYNOPSIS 🌸

void heci_hcsr_set (struct issei_device *idev , u32 reg );

like, that's the whole signature. she's short. she's sweet. she does one thing 💅

---

🎀 ARGUMENTS 🎀

• idev — the device structure 🫶
• reg — the new register value ✨

---

💜 DESCRIPTION 💜

so here's the tea: heci_hcsr_set writes the H_CSR register to the heci device. that's it, that's the function, and she ate 🔥

the one lil plot twist 👀 is that it ignores the H_IS bit, because that bit is write-one-to-zero. so yeah, it does not get touched, no cap 💀
