vmw_surface_...ize_extended(9)

💅 vmw_surface_...ize_extended(9) — bestie edition 🎀

okay so this page lives in the Kernel API Manual, and the header is literally vmw_surface_...ize_extended(9) (yes the ellipsis is really in there, it's giving "we ran out of column width" energy ✨). Buckle up, we're learning about surface sizes today.

🌸 NAME 🌸

vmw_surface_get_serialized_size_extended — returns the number of bytes required for a surface with given parameters. Support for sample count. 🫶

---

✨ SYNOPSIS ✨

u32 vmw_surface_get_serialized_size_extended (SVGA3dSurfaceFormat format
, struct drm_vmw_size base_level_size , u32 num_mip_levels , u32
num_layers , u32 num_samples );

That's the whole signature, no cap. It returns a u32 (the byte count, iykyk) and takes five things. Let's meet them 👇

🦋 ARGUMENTS 🦋

okay so about these bestie… the source doc says -- undescribed -- for every single one of them. Not me making stuff up on the internet — I'm literally reading the page. 💀 So here they are, in order, fully present and accounted for, with the honest truth that the manpage gives zero detail:

• format — SVGA3dSurfaceFormat. The doc's description is literally -- undescribed --. 🙈
• base_level_size — struct drm_vmw_size. Also -- undescribed --. 😭
• num_mip_levels — u32. Also -- undescribed --. 🍓
• num_layers — u32. Also -- undescribed --. 🌈
• num_samples — u32. Also -- undescribed --. 💜

fr fr if you need the real semantics, go read the header file down below — the manpage is not gonna be the one to tell you. 😌

and that's the whole page, slay 💅✨

this little icon came from ./drivers/gpu/drm/vmwgfx in October 2026, and the footer proudly announces itself as vmw_surface_...ize_extended(9) one more time — main character energy, bookending the whole thing 👑🫶 go drink some water and go read that header file bestie 💖
