🌸 evergreen_get_allowed_info_register(9) 🌸

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil function from the radeon crew and honestly it's giving "short but essential" — like a single tweet that somehow explains the whole plot. let's get into it ✨

💫 NAME 💫

evergreen_get_allowed_info_register — the girl whose whole job is to fetch the register for the info ioctl 🎀 like, that's it, that's her job description, and she does it flawlessly.

🌈 SYNOPSIS 🌈

int evergreen_get_allowed_info_register (struct radeon_device *rdev ,
u32 reg , u32 *val );

copy it exactly, no cap, the spacing is the vibe 💅

🦋 ARGUMENTS 🦋

  • rdev — a radeon_device pointer 🫶 literally just the pointer to the radeon device, that's the whole thing.
  • reg — register offset in bytes ⭐ yes, bytes, we're counting in bytes, don't come at me with no other unit.
  • val — register value 💜 the value lives here. that's where the value goes.

🧚 DESCRIPTION 🧚

so the way this works is: it returns 0 for success ✨ or -EINVAL for an invalid register 💀 that's the entire behaviour, bestie — no secret bonus modes, no hidden features, no extra lore. 0 means slay, -EINVAL means the register you handed over was not it. periodt. 🔥

👑 SEE ALSO 👑

the kernel file it lives in (iykyk) is here:

./drivers/gpu/drm/radeon/evergreen.c

and here's the full friend group, the whole squad, every single one of them 🫶 don't skip any, they're all main characters:

🎀 reminder bestie: 0 = success, -EINVAL = invalid register. those are the only two plot twists. 💀

aaaand that's the whole page!! mwah 💋 this came from ./drivers/gpu/drm/radeon, dated October 2026, and it's filed under evergreen_g...nfo_register(9) — go forth and register responsibly, bestie 🌸🦋⭐👑
