amdgpu_vram_mgr_vis_size(9)

💅 amdgpu_vram_mgr_vis_size(9) — like, the Kernel API Manual one, bestie 🎀

okay so this is a page straight outta the Kernel API Manual and it's all about one little function that does one little math thing and honestly? it ate. let's get into it ✨

---

✨ NAME ✨

amdgpu_vram_mgr_vis_size — Calculate visible block size 🦋

---

✨ SYNOPSIS ✨

u64 amdgpu_vram_mgr_vis_size (struct amdgpu_device *adev , struct
gpu_buddy_block *block );

not me copying this exactly because it's giving verbatim and we do NOT edit the synopsis, periodt 💅

---

✨ ARGUMENTS ✨

• adev — an amdgpu_device pointer. yeah. that one. the device bestie 🫶
• block — a DRM BUDDY block structure. it's the block. the buddy. the DRM one 🌸

---

✨ DESCRIPTION ✨

so what does it actually do? it calculates how many bytes of the DRM BUDDY block are inside visible VRAM 💖

that's it. that's the whole thing. it's a little byte-counter for the part of the block that's visible. lowkey iconic, highkey specific 😭

okay that's the page!! and for the cute little sign-off: this one lives in ./drivers/gpu/drm/amd/amdgpu, dated October 2026 (yes, the future, she's ahead of her time 🌈), and it's the amdgpu_vram_mgr_vis_size(9) page of the Kernel API Manual. mwah, bye bestie 💋🎀
