📦 version 7.3.1, in nixpkgs unstable

💖 gmc_v8_0_mc_program(9) 💖

ok so bestie, welcome to the Kernel API Manual ✨ this one's a lil function page from the Linux kernel docs and honestly? it's short, it's sweet, and it does exactly one thing. let's get into it 🫶

🌸 NAME 🌸

gmc_v8_0_mc_program — program the GPU memory controller 💅

like, that's the whole job. it programs the memory controller. main character energy, zero side quests.

✨ SYNOPSIS ✨

void gmc_v8_0_mc_program (struct amdgpu_device *adev );

no return value, no drama — it's a void, so it just does the thing and leaves 😌✨

🎀 ARGUMENTS 🎀

  • adev — amdgpu_device pointer 🦋 that's it, that's the one argument. it's a pointer to the amdgpu_device, which is literally the whole GPU's vibe in struct form. iykyk.

💜 DESCRIPTION 💜

ok so what this actually does, no cap: it sets the location of vram, gart, and AGP in the GPU's physical address space 🌈

and yes bestie, it says (VI) — that's the generation tag right there in the description, so this is the VI-flavored version. keep it in mind 👑

so like, three things get placed into the GPU's physical address space: vram, gart, and AGP. that's the whole paragraph fr fr — short and iconic, we love a concise queen 🎀

🔥 SEE ALSO 🔥

the receipts, the whole friend group, and the file it lives in 💀✨

like, go read the siblings when you're done here, they're all part of the same gmc_v8_0 fam and they all ate 💅🍓

ngl this page is tiny but she's doing her job with zero complaints. read the siblings if you wanna see the whole friend group in action 🧚

ok that's the whole page, bestie!! 💖 this one's from ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026 — you'll see that stamped in the footer of the original, so consider this the cute sign-off version ✨ mwah, go program that memory controller 🌈👑🎀
