Okay so bestie, welcome to the Kernel API Manual page for cpm_muram_addr(9) — yes the (9) is giving "kernel section, don't @ me", and yes we're gonna get through this together 🫶

💖 NAME 💖

cpm_muram_addr — turn a muram offset into a virtual address ✨

No cap, that's literally the whole job. You hand it an offset, it hands you back a virtual address. Glow-up for numbers 💅

---

🌸 SYNOPSIS 🌸

void __iomem * cpm_muram_addr (unsigned long offset );

Look at that signature. void __iomem * — yes it's a pointer, yes it has __iomem on it, and yes you should respect that annotation or the sparse checker will absolutely come for you 💀

🎀 ARGUMENTS 🎀

• offset — the muram offset you want converted 🦋 that's it, that's the whole argument, she's lowkey simple and we love her for it
