✨ rio_write_config_16(9) ✨

okay so bestie, this is a page from the Kernel API Manual and it's literally about writing 16 bits into configuration space. it's giving "small but mighty" energy ngl 💅

🎀 NAME 🎀

rio_write_config_16 — write 16 bits to configuration space. that's it. that's the whole vibe. no cap 💖

🌸 SYNOPSIS 🌸

int rio_write_config_16 (struct rio_dev *rdev , u32 offset , u16 data );

like yes she's a function, yes she returns an int, yes she takes three things. iconic of her honestly 🫶

🦋 ARGUMENTS 🦋

  • rdev — the RIO device. the main character of this whole operation honestly 👑
  • offset — the offset into the device's configuration space. like where exactly we're dropping the data off, iykyk 📍
  • data — the data to be written. this is the payload bestie, the whole reason we're here 💌

✨ DESCRIPTION ✨

so what she does is: she writes 16 bits of data to the specified offset within the RIO device's configuration space. that's the tea ☕ and it's literally that simple. no drama, no hidden catches, just 16 bits going exactly where you tell them to go 🌈

bestie reminder: offset is measured into the device's configuration space, so make sure you're pointing at the right spot 🎯

💜 SEE ALSO 💜

first up, the kernel file where this all lives:

./include/linux/rio_drv.h

and then the whole friend group, in order, because we don't skip anyone in this house 🫶:

mwah 💋 that's the page! this icon ships from the kernel directory ./include/linux and it's stamped October 2026 — go forth and write those 16 bits, bestie, you're gonna slay 🔥
