bdisp_hw_alloc_nodes(9)

💅 bdisp_hw_alloc_nodes — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual entry for bdisp_hw_alloc_nodes — section (9), which is the section for kernel internals, iykyk. this is a real one. pull up a chair. 🎀

---

✨ NAME ✨

bdisp_hw_alloc_nodes —

and yes, the description after the dash is literally empty in the source. nothing. a whole vibe. she said "my name is enough." iconic honestly. 🫶

---

🌸 SYNOPSIS 🌸

int bdisp_hw_alloc_nodes (struct bdisp_ctx *ctx );

that's it. one function, returns an int, takes one pointer. clean. minimal. main character energy. ✨

---

🦋 ARGUMENTS 🦋

• ctx — the bdisp context. that's the whole description, bestie, she's a woman of few words 💅

---

🧚 DESCRIPTION 🧚

so what does she do? she allocates dma memory for nodes. that's the tea. dma memory. for nodes. no cap. 🔥

like yes that's genuinely the entire description in the original and i refuse to invent lore that isn't there — that would be lying to you and we don't do that in this group chat 🙈

---

⭐ RETURN ⭐

returns 0 on success. that's the documented value, periodt. 🎀

ngl the manpage only promises 0 on success — it doesn't spell out what a failure gives you back, so don't come for me, i'm just the messenger 💀
