gfx_v7_0_init_compute_vmid(9)

📦 version 7.3.1, in nixpkgs unstable

💅 gfx_v7_0_init_compute_vmid(9) — the kernel API manual, but make it make sense 💅

okay so bestie, welcome to the gfx_v7_0_init_compute_vmid page, part of the Kernel API Manual. yes it's a kernel function page. no it's not scary. sit down, grab a strawberry 🍓, let's go.

✨ NAME ✨

gfx_v7_0_init_compute_vmid — gart enable

like, that's the whole vibe. the short-and-sweet one-liner is literally "gart enable". iconic. the function name is a whole mouthful but the description is four syllables. balanced, as all things should be 🫶

🌸 SYNOPSIS 🌸

void gfx_v7_0_init_compute_vmid (struct amdgpu_device *adev );

that's it. it returns void — nothing comes back out, it just does the thing and ghosts you 💀 — and it takes exactly one pointer. no more, no less. main character signature, honestly.

🎀 ARGUMENTS 🎀

  • adev — an amdgpu_device pointer. that's the whole argument list. one (1) pointer. it's giving minimalist. it's giving "i don't need a lot, i just need my adev". take a pointer to the amdgpu device and you're set ✨

🦋 DESCRIPTION 🦋

so what does it actually DO. okay. it initializes the compute vmid sh_mem registers. that's the tea, that's the whole job. it's warming up those registers so the compute side knows what's what. no cap, that's literally the entire documented behaviour — don't go reading extra lore into it 🙈

lowkey important to know it's a void function that only takes adev, so if you're out here expecting return values or extra params, that's not the vibe. check the synopsis again bestie 💅

🔥 SEE ALSO 🔥

the kernel file this lives in, for when you wanna read the source and feel something:

./drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c

and now the whole friend group — every single one of these is a real page and yes you should absolutely go read them all (or at least the ones you actually need, we're not gonna pretend 😭):

that's the page, bestie 🌈 it's from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's been gfx_v7_0_init_compute_vmid(9) the whole time. mwah 💋 go initialize something ✨👑
