🦋 mips_cdmm_cur_base(9) — Kernel API Manual, bestie edition 🦋

okay so welcome to mips_cdmm_cur_base(9) from the Kernel API Manual 💖 this is the entry about finding the current physical base address of the CDMM region. lowkey iconic, highkey useful.

✨ NAME ✨

mips_cdmm_cur_base — find the current physical base address of the CDMM region. no cap, that’s the whole assignment 💅

🌸 SYNOPSIS 🌸

phys_addr_t mips_cdmm_cur_base (void );

🎀 ARGUMENTS 🎀

• void — no arguments. literally none. the function said “i need space” and meant it 🫶

⭐ RETURN ⭐

Physical base address of the CDMM region according to the cdmmbase CP0 register, or 0 if the CDMM region is disabled. so if it’s disabled, you get 0 — that’s the vibe check 💀
