💖 amdgpu_vce_sw_init(9) — Kernel API Manual, bestie edition 💖

okay so this is a page straight out of the Kernel API Manual, and yes it's about the AMD GPU driver, and yes it's lowkey a banger. buckle up 🎀

✨ NAME ✨

amdgpu_vce_sw_init — allocate memory for VCE BO

(yes that's the whole name section, it's giving minimalism and honestly? slay 💅)

🦋 SYNOPSIS 🦋

int amdgpu_vce_sw_init (struct amdgpu_device *adev , unsigned long size );

that's it. that's the whole vibe. a function that takes two things and hands you back an int. no cap. ⭐

🌸 ARGUMENTS 🌸

  • adev — the amdgpu_device pointer. like, the whole entire GPU situation. you're holding the keys to the castle here 🔥
  • size — the size for the new BO. this is you deciding how much room the new buffer object gets. choose wisely bestie 🫶

👑 DESCRIPTION 👑

okay so picture this: this is the first step to get VCE online — literally step one, the main character moment 💅 — and what it does is allocate memory for the VCE BO.

the VCE firmware binary doesn't get copied in here, tho. that happens later, over in amdgpu_vce_resume. so this function is out here laying the foundation while the firmware shows up fashionably late 🙈

and bestie, the VCE executes its code from the VCE BO, and it also uses the space in this BO for its stack and data. so it's not just a home, it's a home office, a closet, and a whole storage unit all in one 🎀

ideally this BO should be placed in VRAM for optimal performance — like, that's the dream, that's the goal 🌈 — although technically it also runs from system RAM (albeit slowly). so it works, it's just… not it. slow vibes. 💀

🔮 SEE ALSO 🔮

so the kernel file itself lives at ./drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c — go read it, iykyk 👑

and then the whole friend group, in this exact order because we're not messy:

literally the entire roster. go say hi to all of them 💜

and that's the page!! this one came from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and the whole thing is literally titled amdgpu_vce_sw_init(9) — so yeah, that's the source, the version date, and the whole entire glow-up. bye bestie, go allocate some memory responsibly 🧚‍♀️💖✨
