STRUCT VMW_DX_STREAMOUTPUT(9)

🦋 struct vmw_dx_streamoutput(9) 🦋

okay so bestie, this is a page from the Kernel API Manual and it's literally all about struct vmw_dx_streamoutput — the streamoutput resource metadata vibe. no cap, that's the whole NAME section, she's short and she knows it 💅

---

✨ SYNOPSIS ✨

like, here's the shape of her, exactly as she comes:

struct vmw_dx_streamoutput {
    struct vmw_resource res;
    struct vmw_resource *ctx;
    struct vmw_resource *cotable;
    struct list_head cotable_head;
    u32 id;
    u32 size;
    bool committed;
 };

look at her. iconic. no notes 🎀

🌸 Members 🌸

okay this is the part where we go member by member, because every single one matters, fr fr 🔥

• res — the base resource struct. like the foundation, the main character of the struct world 👑
• ctx — a non-refcounted context that res belongs to. and yes bestie, clock that "non-refcounted" — it's giving "not holding a reference," so don't go assuming it's keeping anything alive 🙈
• cotable — the refcounted cotable holding this Streamoutput. this one DOES hold a reference, unlike her friend ctx above, iykyk ✨
• cotable_head — the list head for the cotable-so_res list. she's the little hook that keeps the list together 🫶
• id — a user-space provided identifier. the userspace said "here, this is her name" 💖
• size — a user-space provided mob size. again, userspace decided, not us 🌸
• committed — a bool that tells you whether the streamoutput is actually created or just pending creation. like is she real-real or is she still loading 😭⏳

👑 SEE ALSO 👑

the kernel file lives right here, go be nosy:

• ./drivers/gpu/drm/vmwgfx/vmwgfx_streamoutput.c

and her whole friend group, all of them, not skipping a single one:

• vmw_dx_streamoutput_unscrub(9)
• vmw_dx_streamoutput_scrub(9)
• vmw_dx_streamoutput_lookup(9)
• vmw_dx_streamoutput_add(9)
• vmw_dx_streamoutput_set_size(9)
• vmw_dx_streamoutput_remove(9)
• vmw_dx_streamoutput_cotable_list_scrub(9)

---

💀 quick vibe check: ctx is non-refcounted, cotable is refcounted — mix those up at your own peril bestie, that's a whole lifetime-management situation.
