STRUCT VMW_CMD_ENTRY(9)

✨ struct vmw_cmd_entry(9) ✨

okay bestie, so this is a page straight out of the Kernel API Manual — yes, the Kernel API Manual, we're in the big leagues now 💅 — and it's all about struct vmw_cmd_entry, which is literally the little info card that describes a command for the verifier. Think of it as the command's profile pic, bio, and settings all rolled into one 🎀

---

🌸 SYNOPSIS 🌸

struct vmw_cmd_entry {
    int (*func) (struct vmw_private *, struct vmw_sw_context *,
SVGA3dCmdHeader *);
    bool user_allow;
    bool gb_disable;
    bool gb_enable;
    const char *cmd_name;
 };

like, that's the whole shape of it. five little fields, maximum main character energy 👑

💖 Members 💖

• func — the call-back that handles the command. this is the one doing the actual work, no cap ✨
• user_allow — tells you whether this command is allowed from the execbuf ioctl. it's giving permission slip vibes 🫶
• gb_disable — whether the command is disabled if guest-backed objects are available.
• gb_enable — whether the command is enabled iff guest-backed objects are available. note the "iff" bestie, that's a real logical condition, not just a vibe 😭
• cmd_name — the name of the command. literally just the name. iconic, honestly 🌟

so there's a lot here and we are NOT skipping any of it, periodt. first up, the kernel file itself:

---

💀 real talk: that SEE ALSO list is a whole friend group and yes, __vmw_execbuf_release_pinned_bo(9) and vmw_execbuf_release_pinned_bo(9) are two different functions — the double underscore one is not a typo, do NOT merge them in your head bestie 🙈

and that's the page! 🍓 shoutout to the source tree ./drivers/gpu/drm/vmwgfx and the date stamp October 2026 — that's the version/date tea, go drink some water and go read vmwgfx_execbuf.c 💜🧚
