yamon_dt_append_memory(9)

💅 yamon_dt_append_memory — bestie edition 🎀

okay so this is from the Kernel API Manual, section 9, and the function is literally called yamon_dt_append_memory. say it with me: yamon_dt_append_memory. iconic name, no notes ✨

---

🌸 NAME 🌸

yamon_dt_append_memory — append YAMON-provided memory info to /memory 🫶

---

💖 SYNOPSIS 💖

int yamon_dt_append_memory (void *fdt , const struct yamon_mem_region
*regions );

like yes bestie we're calling it with an fdt and a regions pointer, keep up 💅

---

🦋 ARGUMENTS 🦋

• fdt — the FDT blob. that's the whole vibe. 🧚
• regions — a zero size terminated array of physical memory regions. yes, the termination is a zero size, don't forget it or it's giving infinite loop energy 😭

---

✨ DESCRIPTION ✨

So what it does is generate a /memory node in fdt, based upon memory size information provided by YAMON in its environment and the regions array. both. together. slay 💜

Literally the whole job is: YAMON says how much memory, you hand over your regions, and boom — /memory node gets generated in the fdt. periodt.

---

🔥 RETURN 🔥

0 on success, else -errno. that's it, that's the return value. negative errno is the "something went wrong bestie" signal 💀

and that's a wrap, bestie! written from ./arch/mips/include/asm, dated October 2026, and yes the page is literally named yamon_dt_append_memory(9) — go off, kernel docs 💅🎀🌸
