STRUCT DRM_VMW_GB_SURFACE_CREATE_EXT_REQ(9)

💖 struct drm_vmw_gb_surface_create_ext_req(9) 💖

okay so this is from the Kernel API Manual, bestie — it's the struct drm_vmw_gb_surface_create_ext_req(9) page, and honestly it's giving "underrated supporting character who actually carries the whole plot." let's get into it 🫶

✨ NAME ✨

struct drm_vmw_gb_surface_create_ext_req — and that's literally it, no little tagline after the dash. the manpage said "no notes." iconic of it ngl 💅

---

🌸 SYNOPSIS 🌸

okay bestie, here's the whole shape of it, copy it exactly, don't be weird about it:

struct drm_vmw_gb_surface_create_ext_req {
    struct drm_vmw_gb_surface_create_req base;
    enum drm_vmw_surface_version version;
    __u32 svga3d_flags_upper_32_bits;
    __u32 multisample_pattern;
    __u32 quality_level;
    __u32 buffer_byte_stride;
    __u32 must_be_zero;
};

like. look at her. seven fields, all business, zero filler 💜

🎀 Members 🎀

• base — the surface create parameters. it's the whole struct drm_vmw_gb_surface_create_req riding shotgun in here, main character energy fr 🔥
• version — which version of the surface create ioctl you're on, typed as enum drm_vmw_surface_version. version check bestie, always 🦋
• svga3d_flags_upper_32_bits — the upper 32 bits of the svga3d flags. yes, the top half only. the lower half lives somewhere else, we don't ask questions ✨
• multisample_pattern — the multisampling pattern, used when msaa is supported. msaa girlies rise 🌈
• quality_level — precision settings for each sample. it's giving "how much detail do you want per sample, be honest" 💀
• buffer_byte_stride — buffer byte stride. that's it, that's the field, short and slay 🎀
• must_be_zero — reserved for future usage. so like… set it to zero, girl. the name is literally a whole instruction 😭

🦋 Description 🦋

so this struct is the input argument to the DRM_VMW_GB_SURFACE_CREATE_EXT Ioctl. and plot twist — it's also part of the output argument for the DRM_VMW_GB_SURFACE_REF_EXT Ioctl. dual-purpose queen, we love to see it 👑

and that's the page bestie!! this one lives in ./include/uapi/drm, dated October 2026, and it goes by struct drm_v...eate_ext_req(9) when it's being shy (which, honestly, the truncated title is a vibe). mwah, study it, love it, cite it correctly 💖✨🎀🦋🌸💅
