vmw_kms_stdu_surface_clip(9)

💅 vmw_kms_stdu_surface_clip — the kernel API manual, but make it make sense

okay so bestie, welcome to vmw_kms_stdu_surface_clip(9) ✨ the kernel API manual page for one very specific little callback. it's short, it's sweet, it's giving "tiny function, big responsibilities." let's get into it 🫶

---

🌸 NAME 🌸

vmw_kms_stdu_surface_clip — the callback that encodes a surface copy command cliprect. that's literally its whole job and it does it slayfully 💅

---

⭐ SYNOPSIS ⭐

void vmw_kms_stdu_surface_clip (struct vmw_kms_dirty *dirty );

no cap, that's the whole signature. returns void — it's a callback, it's not here to give you answers, it's here to do the thing 🔥

---

🎀 ARGUMENTS 🎀

• dirty — the closure structure. that's it. that's the argument. it's the little container of context that gets passed around so the callback knows what it's working with 🧚

---

🦋 DESCRIPTION 🦋

so what does it actually do, you ask? it encodes a surface copy command cliprect — and then it updates the bounding box for the copy. that's it. two jobs, both essential, both iconic 👑

like, think of it as the function that says "okay here's the clip rect, and hey, while we're at it, let's update the bounding box so nothing gets lost." it's the main character of the copy-command pipeline, lowkey 🌈
