vmw_surface_define_size(9)

💅 vmw_surface_define_size(9) — the Kernel API Manual era 🎀

okay so bestie, buckle up, because we're in the Kernel API Manual today and this one is a whole little function that just... does math for you. no cap. it's vmw_surface_define_size, and yes it lives in the kernel, and no it's not scary, come on. 🦋

---

✨ NAME ✨

vmw_surface_define_size — compute the fifo size for a surface define command. that's it. that's the whole gig. 💖

---

🌸 SYNOPSIS 🌸

uint32_t vmw_surface_define_size (const struct vmw_surface *srf );

like, you hand it a surface pointer and it hands you back a uint32_t. the way that signature just works. 🔥

---

🎀 ARGUMENTS 🎀

• srf — pointer to a struct vmw_surface. that's your surface, your main character, the thing we're sizing a command for. 🫶

---

💜 DESCRIPTION 💜

so what does it actually do? it computes the required size for a surface define command — the command that defines the surface represented by srf. 🧚

that's the vibe check: give it a surface, get back the size the define command needs. it's giving "backend math but make it cute". no side quests, no surprises, just sizing. ✨
