mips_cm_phys_base(9)

💅 mips_cm_phys_base(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function from the MIPS corner of the kernel and honestly? she's short but she matters 🎀

---

🌸 NAME 🌸

mips_cm_phys_base — grab the physical base address of the CM, that's the whole job, no cap 💖

---

✨ SYNOPSIS ✨

phys_addr_t mips_cm_phys_base (void );

like, that's it. that's the whole signature. she's tidy 👑

---

🦋 ARGUMENTS 🦋

• void — no arguments. zero. none. she takes nothing from you, she just gives 🫶

---

🧚 DESCRIPTION 🧚

okay so here's the tea ☕ this function returns the physical base address of the Coherence Manager global control block — and if there's, like, no Coherence Manager present at all? she returns 0. simple as that 💀

she's providing a default implementation which reads the CMGCRBase register where that register is available 👀 and here's the iconic part: platforms that figure out this address some other way can totally override her — you just define a function with the same prototype and you've stolen the spotlight, main character energy fr fr 🌟

ngl if you ever override this default, double-check your prototype matches exactly — same prototype or it's not the same function, bestie 🙈

and that's a wrap, pookie 🎀 this page came from ./arch/mips/include/asm and she's dated October 2026 — go forth and find that base address, iykyk 💅💖
