vsp1_dl_body_pool_create(9)

💅 vsp1_dl_body_pool_create(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're in kernel-land today and honestly? it slaps. this page is about vsp1_dl_body_pool_create, and no I will not be pronouncing all those underscores out loud, but I will explain it beautifully. 🫶

✨ NAME ✨

vsp1_dl_body_pool_create — create a pool of bodies from a single allocation. literally one allocation, many bodies. it's giving efficiency icon behavior. 👑

---

🌸 SYNOPSIS 🌸

struct vsp1_dl_body_pool * vsp1_dl_body_pool_create (struct vsp1_device
*vsp1 , unsigned int num_bodies , unsigned int num_entries , size_t
extra_size );

like yes the args got line-wrapped, that's just how the doc came, we don't fix what isn't broken 💅

---

🎀 ARGUMENTS 🎀

• vsp1 — the VSP1 device. the main character of this whole situation, ngl.
• num_bodies — how many bodies we're allocating. that's the count, bestie, set it right.
• num_entries — the maximum number of entries that a body can contain. max! not "somewhere around", not "vibes-based" — the max. 🙈
• extra_size — extra allocation provided for the bodies. yes it's extra. yes it's on purpose. slay.

---

🦋 DESCRIPTION 🦋

So what are we actually doing? We allocate a pool of display list bodies, and each one has enough memory to hold the requested number of entries plus extra_size. one allocation, all the bodies, chef's kiss. 🔥

On success you get back a pointer to a pool. On failure — and this is the part where you go 😭 — it returns NULL if memory can't be allocated. no cap, that's the whole deal: NULL means go check your memory situation.
