✨ gfx_v8_0_init_compute_vmid(9) ✨

okay so bestie, we're in the Kernel API Manual today and this little function is literally the moment gart enable happens 💅 no cap, that's what the NAME section says, and we're not gonna argue with the NAME section.

---

🌸 NAME 🌸

gfx_v8_0_init_compute_vmid — gart enable 🫶

like, that's the whole pitch. short. sweet. iconic.

---

🦋 SYNOPSIS 🦋

void gfx_v8_0_init_compute_vmid (struct amdgpu_device *adev );

it returns void (so, nothing, she gives nothing back and that's valid 💀) and it takes exactly one (1) argument. one. singular. main character energy.

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. that's it, that's the whole arg list. just hand her the device pointer and let her cook 🔥

---

💖 DESCRIPTION 💖

so what does she do? she initializes the compute vmid sh_mem registers. periodt. 🎯

ngl that's the entire description in the original and I'm not about to invent lore that isn't there — the manpage said "Initialize compute vmid sh_mem registers" and I'm relaying it to you verbatim-in-spirit because the facts do not change, only the vibe ✨

vibe check: passed 🌈

👑 SEE ALSO 👑

• Kernel file ./drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c — like, go read the source bestie, she's right there 📖
• gfx_v8_0_get_gpu_clock_counter(9)
• gfx_v8_0_get_hdp_flush_mask(9)

both of those are her siblings and honestly they're all serving in the same file 💜
