STRUCT VMW_CMDBUF_ALLOC_INFO(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

struct vmw_cmdbuf_alloc_info — the little metadata bundle that keeps track of a command buffer space allocation, bestie 💅

This one lives in the Kernel API Manual, and it's lowkey just three fields doing a very specific job. No cap.

✨ SYNOPSIS ✨

struct vmw_cmdbuf_alloc_info {
    size_t page_size;
    struct drm_mm_node *node;
    bool done;
 };

🎀 Members 🎀

Okay so there are literally three things in here, and each one is doing main character work:

  • page_size — the size of the command buffer space you're asking for, measured in pages. That's the ask 🫶
  • node — a pointer to the range manager node. That's the hookup to the range manager, iykyk 🔥
  • done — a bool that's true if this allocation has actually succeeded. It's giving "did we slay or did we flop" energy 💀
Heads up: done being true means this allocation has succeeded. Like, that's the whole vibe check for the struct — don't read it as anything fancier than that 🙈

🌈 SEE ALSO 🌈

The kernel file this all hangs out with is ./drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c, and honestly the friend group is extensive. Obsessed with how many of these there are, honestly — periodt:

and that's the whole page, bestie ✨ This lil doc came to you straight out of ./drivers/gpu/drm/vmwgfx, dated October 2026, and it's filed under struct vmw_cmdbuf_alloc_info(9) in case you need to find it again. Go forth and allocate responsibly 🎀🦋💜
