mei_txe_reg_write(9)

✨ NAME ✨

Okay so bestie, this page is straight out of the Kernel API Manual, section 9, and the function is mei_txe_reg_write — its whole job is Writes 32bit data to the txe device. That's the assignment, no cap. It's a void function, so it lowkey just does the write and doesn't hand anything back. Periodt. 💅

🌸 SYNOPSIS 🌸

       void mei_txe_reg_write (void __iomem *base_addr , unsigned long offset ,
       u32 value );

That's the exact signature, fr fr — kernel C realness. 🫶

🎀 ARGUMENTS 🎀

Three args, three little besties:

• base_addr — registers base address. This is where the register block lives, typed as void __iomem *.
• offset — register offset. The exact spot inside the register block you're aiming at, typed as unsigned long.
• value — the value to write. The main character payload: a u32 with the data you're sending. ✨
