ice_pkg_buf_alloc_section(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_pkg_buf_alloc_section(9) — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the ice driver, you're building a package buffer, and you need to carve out room for a section. that's literally this function. she's a helper, she's essential, and she's about to make your whole build go 🫶

🌸 NAME 🌸

ice_pkg_buf_alloc_section — and ngl bestie, the original page has no description line here at all. iconic of her honestly, she lets the synopsis do the talking 💅

✨ SYNOPSIS ✨

void * ice_pkg_buf_alloc_section (struct ice_buf_build *bld , u32 type ,
u16 size );

she returns a void *, she takes three args — keep reading, we're going through every single one 🎀

🦋 ARGUMENTS 🦋

  • bld — pointer to the pkg build (allocated by ice_pkg_buf_alloc). like, this is the build object you already made, don't come in here with a random pointer, that's not the vibe 🙈
  • type — the section type value. yes, the actual type. slay 💖
  • size — the size of the section to reserve, in bytes. bytes, bestie. bytes. 📏

👑 DESCRIPTION 👑

so what does she actually do? she reserves memory in the buffer for a section's content, and she updates the buffer's status accordingly ✨ that's the whole job and she does it flawlessly.

and then — this is the good part — she returns a pointer to the first byte of the section start within the buffer. so you take that pointer, and you use it to fill in the section contents. that's the whole flow, iykyk 🧚

⭐ real talk: that returned pointer is your main character. don't lose it, don't overwrite it, just write your section contents through it.

💀 NOTE 💀

all package contents must be in Little Endian form. not a suggestion. not a "well actually". it's giving non-negotiable 🔥
