vmw_stdu_bo_cpu_commit(9)

💅 vmw_stdu_bo_cpu_commit — like, the Kernel API Manual, section 9, bestie ✨

okay so real talk, this is a page straight out of the Kernel API Manual (section 9, the kernel-functions girlies), and today's main character is vmw_stdu_bo_cpu_commit. she's a callback. she does a CPU blit. she's lowkey essential. let's get into it 🎀

---

🌸 NAME 🌸

vmw_stdu_bo_cpu_commit — a callback that does a CPU blit from a buffer object, no cap 💖

---

✨ SYNOPSIS ✨

void vmw_stdu_bo_cpu_commit (struct vmw_kms_dirty *dirty );

like, that's the whole signature. she takes one thing and returns nothing. void queen. 👑

---

🦋 ARGUMENTS 🦋

• dirty — the closure structure. that's it, that's the argument. she just wants her dirty struct and she's happy 🫶

---

💅 DESCRIPTION 💅

so here's the vibe check: sometimes you literally cannot create a proxy surface in a 2D VM. like, it's just not happening. and in that special case, we have to do a CPU blit ourselves. that's the whole job. no proxy surface? no problem. we roll up our sleeves and we blit it on the CPU. it's giving "fine, I'll do it myself" energy 😭✨

for real though, this is the special case path — the fallback when the proxy-surface route isn't available in a 2D VM. don't forget it. 🙈
