thc_i2c_rx_max_size_enable(9)

🌸 thc_i2c_rx_max_size_enable 🌸

okay bestie, welcome to the Kernel API Manual, section 9 — yes we're in the deep kernel lore today and honestly? it's giving main character energy 💅

---

✨ NAME ✨

thc_i2c_rx_max_size_enable — literally just turns the I2C Rx max input size control on (or off, she's versatile 🦋)

---

✨ SYNOPSIS ✨

int thc_i2c_rx_max_size_enable (struct thc_device *dev , bool enable );

---

✨ ARGUMENTS ✨

• dev — the pointer to the THC private device context 🫶 like, the whole vibe of the device lives in here
• enable — whether we're enabling max input size control or not, simple as that ✨

---

✨ DESCRIPTION ✨

So what she actually does: this function enables or disables the I2C RxDMA max input size control feature. Both directions, she's flexible 💖

⚠️ okay so this is the important part, no cap: max input size control only can be enabled after the max input size was set by thc_i2c_set_rx_max_size. Like, set the size FIRST, then enable. Order matters, bestie, do not skip a step 🙈

---

✨ RETURN ✨

• 0 on success — slay 💅
• other error codes on failure — not slay, go check your error code 😭
