vmw_shader_lookup(9)

📦 version 7.3.1, in nixpkgs unstable

💅 vmw_shader_lookup — bestie, let's find that shader

okay so this is a page from the Kernel API Manual (section 9, kernel-space icon behavior only, no userland shenanigans) and it's literally about one thing: looking up a compat shader. that's it. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

struct vmw_resource * vmw_shader_lookup (struct vmw_cmdbuf_res_manager
*man , u32 user_key , SVGA3dShaderType shader_type );

like, yes, the line break in the middle is ugly, but that's the signature, bestie — copy it exactly and don't come for me. 💅

🌸 ARGUMENTS 🌸

  • man — pointer to the command buffer managed resource manager, which is the thing that identifies the shader namespace. think of it as the group chat where this shader lives. 🫶
  • user_key — the user space id of the shader. it's giving "i'm looking for my friend, here's their @". ✨
  • shader_type — the shader type. congrats, that's the whole description, no notes. 😭

💖 DESCRIPTION 💖

so here's the tea: if the shader was found, you get back a refcounted pointer to a struct vmw_resource. refcounted means somebody's keeping tally, so be a good citizen and don't just ghost it. 👑

if it wasn't found? you get an error pointer instead. not NULL, babe — an error pointer. use your IS_ERR() checks, iykyk. 🧚

that's genuinely the entire function. short and iconic. periodt. 💀

🦋 SEE ALSO 🦋

like the whole shader friend group, all here, all slaying. 🔥

ngl the "cotable" one is a whole mouthful, but i believe in you. 🙈

and that's the page!! 💜 source ./drivers/gpu/drm/vmwgfx, dated October 2026, and the manual is vmw_shader_lookup(9) in the Kernel API Manual — mwah, go read your error pointers responsibly bestie 🍓🌈⭐
