thc_spi_write_config(9)

💅 thc_spi_write_config(9) — like, the SPI write config glow-up

Hey bestie, welcome to the thc_spi_write_config page from the Kernel API Manual ✨. Yes, it's a kernel function, yes it's got six arguments, and yes we're gonna get through it together. Grab your iced coffee 🍓.

🌸 NAME 🌸

thc_spi_write_config — the one that configures SPI bus write attributes. That's it. That's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

int thc_spi_write_config (struct thc_device *dev , u32 spi_freq_val ,
u32 io_mode , u32 opcode , u32 spi_wr_mps , u32 perf_limit );

Returns an int, takes six things, lowkey iconic honestly 👑

---

🦋 ARGUMENTS 🦋

Six of them. Six! Let's go one by one, no skipping, we don't do that here 🫶

• dev — the pointer of THC private device context. Your main character struct, fr fr.
• spi_freq_val — the SPI write frequency value 🌈
• io_mode — the SPI write IO mode ✨
• opcode — the write opcode. It's giving "instruction" energy.
• spi_wr_mps — the SPI write max packet size 📦
• perf_limit — the performance limitation, and plot twist: it's measured in units of 10us ⏱️

---

💜 RETURN 💜

0 on success, other error codes on failed. So basically if you get 0, slay. Anything else? That's a no from the kernel, bestie 😭

🧚 Sign-off 🧚

This little gem lives at ./drivers/hid/intel-thc-hid/in... and it's dated October 2026 — yes, the future, she's ahead of her time ⭐. Manual section thc_spi_write_config(9), Kernel API Manual, and honestly? Obsessed. Bye bestie, go configure those write attributes 💖✨🎀
