vmw_collect_dirty_vbs(9)

💅 vmw_collect_dirty_vbs(9) — like, the Kernel API Manual page, bestie ✨

okay so this is a page from the Kernel API Manual and honestly? it's giving "niche but iconic." we're in the vmwgfx binding crew today 🎀

---

🌸 NAME 🌸

vmw_collect_dirty_vbs — builds up SVGA3dVertexBuffer data so a SVGA3dCmdDXSetVertexBuffers command has something cute to wear 💖

---

✨ SYNOPSIS ✨

void vmw_collect_dirty_vbs (struct vmw_ctx_binding_state *cbs , const
     struct vmw_ctx_bindinfo *bi , unsigned long *dirty , u32 max_num );

like, it returns void, so don't go looking for a return value, she simply doesn't do that 💅

---

🦋 ARGUMENTS 🦋

• cbs — pointer to the context's struct vmw_ctx_binding_state. the main character of this whole situation ngl 🫶
• bi — pointer to wherever the binding info array lives inside cbs. she points, we follow ✨
• dirty — bitmap showing which bindings still need to be emitted. the "who's still got something to say" list 💀
• max_num — the maximum number of entries that can fit in the bi array. know her limits, respect her limits 👑

---

💜 DESCRIPTION 💜

so basically, vmw_collect_dirty_vbs scans the bi array looking for bindings that actually need to be emitted, then builds up a buffer of SVGA3dVertexBuffer data out of them. it's giving "curated collection" 🌈

and on output — this is the part, lowkey the best part — you get three things handed back to you through cbs:

• cbs->bind_cmd_count — how many bindings are getting emitted 🔥
• cbs->bind_first_slot — the index of the first emitted binding ⭐
• cbs->bind_cmd_buffer — the actual command data, right there, ready to go 💖

so like, that's the whole vibe. scan, collect, fill in those three fields. periodt ✨

ngl there's no BUGS section, no exit statuses, no signals on this one — just vibes and vertex buffers. don't go making stuff up 🫶

and that's the page!! this little beauty lives over in ./drivers/gpu/drm/vmwgfx, dated October 2026, and yeah — it's a vmw_collect_dirty_vbs(9) situation from start to finish 💖✨🎀 slay, go emit those bindings bestie 🌸
