💅 register_dca_provider(9) — a Kernel API Manual moment 💅

okay so bestie, welcome to the Kernel API Manual, where today's main character is register_dca_provider. It's short, it's sweet, and honestly it's giving "the docs said ✨figure it out✨" energy, but we're gonna walk through it together 🫶

🌸 NAME 🌸

register_dca_provider — literally just register a dca provider, no cap.

And because the NAME section said it all in one breath, here's the tea it dropped on the way:

  • dca — a struct created by alloc_dca_provider()
  • dev — the device providing dca services

that's it, that's the whole name section, she's concise 💅

✨ SYNOPSIS ✨

int register_dca_provider (struct dca_provider *dca , struct device *dev );

it returns an int, it takes two pointers, and yes the spacing is exactly like that — we do not edit the sacred code block 🙈

🎀 ARGUMENTS 🎀

  • dca — -- undescribed --
  • dev — -- undescribed --

ok so not me reading this and going 😭😭😭 — the manpage literally ships both arguments as -- undescribed --. That's not me being lazy, bestie, that's the actual state of the docs. No shame in it, we just vibe check it and move on. (If you want the deets, the NAME section up top is where the crumbs are: dca is the struct from alloc_dca_provider(), and dev is the device providing dca services. periodt.)

fr fr: don't go inventing extra meaning here. If the page says -- undescribed --, the page says -- undescribed --. We report, we don't speculate 💀
