thc_spi_read_config(9)

💅 thc_spi_read_config(9) — Kernel API Manual 🌸

okay bestie, welcome to the group chat for thc_spi_read_config ✨ This is a page straight out of the Kernel API Manual, and honestly? It's giving "small function, big job" energy. Sit down, grab a strawberry 🍓, and let's get into it.

🎀 NAME 🎀

thc_spi_read_config — the cutie that configures SPI bus read attributes 💖

No cap, that's literally the whole job. It goes in, it sets up how your SPI bus reads stuff, and it leaves. Iconic behavior.

---

✨ SYNOPSIS ✨

int thc_spi_read_config (struct thc_device *dev , u32 spi_freq_val , u32
io_mode , u32 opcode , u32 spi_rd_mps );

Bestie, look at that signature — five params, returns an int, so clean, so demure 🎀

---

🦋 ARGUMENTS 🦋

• dev — the pointer of the THC private device context 💜 like, this is your main character. It's a pointer to the THC private device context, and everything else kind of hangs off it.
• spi_freq_val — the SPI read frequecy value 🔥 (and yes, we're keeping that spelling exactly as the kernel wrote it, no notes, we don't edit the source, periodt).
• io_mode — the SPI read IO mode 🌈 the vibe check for how reads travel on the bus.
• opcode — the read opcode ⭐ the actual instruction code for reads. Small but mighty, iykyk.
• spi_rd_mps — the SPI read max packet size 👑 literally how big a read packet is allowed to get.

---

💀 RETURN 💀

• 0 on success 🫶
• other error codes on failed 🥲 (that's failed, keep it exactly like that, fr fr — no cleanup, no edits, we respect the original)

Heads up bestie: if it comes back non-zero, something's not slaying. The page just says "other error codes on failed," so that's all we've got to go on — don't let anyone tell you more than the manpage does.

🧚 Sign-off 🧚

This little masterpiece comes from source path ./drivers/hid/intel-thc-hid/in… and is dated October 2026 🌸 and the page itself is thc_spi_read_config(9). That's the whole footer, we're not skipping it, we're celebrating it 🎉💜

Alright, go configure some SPI read attributes. Slay 💅✨
