sba_dump_ranges(9)

💅 sba_dump_ranges(9) — Kernel API Manual edition 💅

okay so welcome to the Kernel API Manual, bestie — this one is a tiny little debugging moment and it's honestly giving “look at your ranges” energy ✨

---

💖 NAME 💖

sba_dump_ranges — debugging only - print ranges assigned to this IOA 🎀

---

✨ SYNOPSIS ✨

one function, one argument, zero plot twists:

void sba_dump_ranges (void __iomem *hpa );

---

🎀 ARGUMENTS 🎀

• hpa — base address of the sba. that's the whole argument, bestie, no cap 🫶

---

🦋 DESCRIPTION 🦋

okay so what it does is print the MMIO and IO Port address ranges forwarded by an Astro/Ike/RIO IO Adapter (aka Bus Converter). that's the vibe. it's marked debugging only in the NAME, so it's literally here to print ranges assigned to this IOA and nothing more dramatic 💅
