plat_get_fdt(9)

🌸 plat_get_fdt(9) — a Kernel API Manual moment 🌸

okay so bestie, you're reading plat_get_fdt(9) from the Kernel API Manual and honestly? it's a little guy with a big job. let's get into it 💅

---

✨ NAME ✨

plat_get_fdt — hand you a pointer to the platform's device tree blob, no cap 🎀

---

🦋 SYNOPSIS 🦋

void * plat_get_fdt (void );

---

💖 ARGUMENTS 💖

• void — literally no arguments. nothing. zero. she takes nothing and gives everything 🫶

---

👑 DESCRIPTION 👑

so this function is the platform-independent API for getting a pointer to the flattened device tree blob. iconic behaviour fr fr ✨

here's the vibe: the interface between the bootloader and the kernel is not consistent across platforms — it's giving chaos, honestly 😭 — so it's necessary to provide this API so that common startup code can locate the FDT. one function to find them all, basically 🌈

and who's using it? the KASLR code, that's who — it calls this to get command line arguments and the random seed out of the device tree. so any platform wishing to use KASLR should provide this API and select SYS_SUPPORTS_RELOCATABLE. that's the deal, bestie, both parts, no skipping 💜

---

🔥 RETURN 🔥

Pointer to the flattened device tree blob. that's it, that's the whole return value, she's simple and she slays ⭐

💀 tiny reminder before you go: the bootloader/kernel interface is genuinely inconsistent across platforms, so don't go assuming it's uniform — that's literally why this API exists. be normal about it 🙈

mwah, that's the whole page! sourced from ./arch/mips/include/asm, dated October 2026, and still serving plat_get_fdt(9) realness. go forth and locate that FDT, bestie 💖🎀🦋👑
