quicki2c_dma_init(9)

💅 quicki2c_dma_init(9) — your girl's guide to the Kernel API Manual ✨

Okay so bestie, buckle up 🎀 this one's from the Kernel API Manual, and it's literally about getting your QuickI2C device's DMA all set up and cute. Let's get into it 💖

---

🌸 NAME 🌸

quicki2c_dma_init — configure THC DMA for a QuickI2C device. That's the whole vibe, no cap ✨

---

🦋 SYNOPSIS 🦋

int quicki2c_dma_init (struct quicki2c_device *qcdev );

Like, it returns an int and takes exactly one arg. Simple, clean, iconic 💅

---

🎀 ARGUMENTS 🎀

• qcdev — pointer to the quicki2c_device structure. That's your device bestie right there 🫶

---

✨ DESCRIPTION ✨

So here's the tea ☕: this function takes TIC's parameters — things like max input length and max output length — and uses them to allocate the THC DMA buffers and configure the THC DMA engines.

Basically it's doing the whole backstage setup so your DMA can have main character energy later. Obsessed, honestly 🔥

---

💜 RETURN 💜

• 0 if it slays (success) ✅
• an error code if it doesn't (failure) 😭

Periodt.

Heads up bestie 💀 the source line got cut off in the manual — it just says ./drivers/hid/intel-thc-hid/in... — so don't come for me, that's literally all it gave us 🙈
