vmw_cmdbuf_man_destroy(9)

💅 vmw_cmdbuf_man_destroy(9) — Kernel API Manual, bestie 💖

Okay so real talk, we're deep in the Kernel API Manual today and the page we're reading is vmw_cmdbuf_man_destroy. Yes it's a mouthful, no you don't have to say it out loud. It's giving "final boss of cleanup functions" and honestly? Iconic. 🎀

---

✨ NAME ✨

vmw_cmdbuf_man_destroy — take down a command buffer manager.

Like, gently. But also permanently. It's the breakup arc. 💔

---

✨ SYNOPSIS ✨

void vmw_cmdbuf_man_destroy (struct vmw_cmdbuf_man *man );

Not me copying this exactly, character for character, weird spacing and all. That's the assignment and I ate. 💅

---

✨ ARGUMENTS ✨

• man — pointer to a command buffer manager. That's your main character right there 🫶. You're handing it over, it's getting taken down, everyone say bye.

---

✨ DESCRIPTION ✨

Okay so what even happens here: this function idles the command buffer manager, and then destroys it. Idle first, destroy second. Order matters, bestie, do not flip it 🙈.

That's literally the whole thing. Two steps. Very demure, very mindful. It's cleanup with main character energy and it does exactly what it says on the tin ✨.

💀 Lowkey a reminder: this page is just the destroy pass. Idles first, destroys after. If you skipped the idle part, that's not a vibe and it's not what the page says.

And that's the whole page, bestie! 💖 It lives over in ./drivers/gpu/drm/vmwgfx, it's dated October 2026, and the manual name is vmw_cmdbuf_man_destroy(9) in case you forgot already (I wouldn't blame you, that's so many letters 😭). Slay your cleanup. 🌈✨🦋
