radeon_atombios_fini(9)

📦 version 7.3.1, in nixpkgs unstable

💖 radeon_atombios_fini 💖

okay so real talk, this is radeon_atombios_fini, a page straight out of the Kernel API Manual, and it's basically the closing credits function for the atombios era of the radeon driver. we're talking cleanup duty, bestie. the tidy-up. the "ok we're done here, lights off" moment ✨

🌸 NAME 🌸

radeon_atombios_fini — frees the driver info and callbacks for atombios, no cap 🫶

🎀 SYNOPSIS 🎀

void radeon_atombios_fini (struct radeon_device *rdev );

that's it, that's the whole signature. void return, one pointer in, nothing out. she's simple and she knows it 💅

🦋 ARGUMENTS 🦋

  • rdev — the radeon_device pointer 🌈. literally just the device struct, hand it over and she'll do her thing.

⭐ DESCRIPTION ⭐

so what does she actually do? okay:

radeon_atombios_fini frees the driver info and the register access callbacks for the ATOM interpreter, and that's for r4xx+ cards, iykyk 🧚

when does she get called? at driver shutdown. that's the moment. main character energy of "everything must go" 🕯️

not me being the one to free the callbacks — if you're calling this at any other time you're lowkey in the wrong place, bestie 🫣

🔥 SEE ALSO 🔥

okay this list is LONG, so buckle in, she brought her whole friend group 💀

first up, the kernel file herself:

  • ./drivers/gpu/drm/radeon/radeon_device.c

and now the whole squad, in order, all of them, don't skip 🎀:

like I said. whole friend group. invite them all to the group chat 💜

and that's the page!! 🌸 sign-off time: this cutie lives under ./drivers/gpu/drm/radeon, and the version stamp says October 2026. go forth and shut down your drivers responsibly, bestie 🫶✨💅
