vmw_cmdbuf_reserve_cur(9)

📦 version 7.3.1, in nixpkgs unstable

💅 vmw_cmdbuf_reserve_cur 💅

okay bestie, so this is a page from the Kernel API Manual — it's vmw_cmdbuf_reserve_cur(9), and honestly? it's a little icon doing one very specific job. let's get into it 🫶

✨ NAME ✨

vmw_cmdbuf_reserve_cur — reserve space for commands in the current command buffer. that's it, that's the whole vibe. lowkey obsessed with how direct it is 💖

🌸 SYNOPSIS 🌸

void * vmw_cmdbuf_reserve_cur (struct vmw_cmdbuf_man *man , size_t size
, int ctx_id , bool interruptible );

like, look at her. returns a void *, takes four things, no drama 💅

🎀 ARGUMENTS 🎀

  • man — the command buffer manager. the main character, the one holding everything together ✨
  • size — the requested size of the commands. how much room you're asking for, fr fr.
  • ctx_id — the context id, if any. otherwise you set it to SVGA3D_REG_INVALID 🦋 (yes, exactly that, don't be creative).
  • interruptible — whether to sleep interruptible while waiting for space. basically: how do you want to wait, bestie? 😴

💜 DESCRIPTION 💜

so here's the tea: if it works, it returns a pointer to command buffer space. successful slay 🎉

otherwise? it returns an error pointer. not a slay. 😭💀

that's genuinely the whole description — no hidden lore, no extra paragraphs. it's giving "short and efficient" and we respect it 👑

🔥 SEE ALSO 🔥

the whole friend group, assembled 💖 go check them out:

ngl bestie, remember the golden rule: ctx_id goes to SVGA3D_REG_INVALID when there's no context id. that's the detail everyone forgets and then wonders why things are weird 🙈

and that's the page!! 🧚‍♀️ huge thank you to ./drivers/gpu/drm/vmwgfx for bringing us this content, dated October 2026, filed under vmw_cmdbuf_reserve_cur(9). mwah 💋 periodt.
