idpf_map_rem...ng_mmio_regs(9)

💅 idpf_map_rem...ng_mmio_regs — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of idpf_map_rem...ng_mmio_regs(9), straight out of the Kernel API Manual. yes the title is lowkey truncated in the header (idpf_map_rem...ng_mmio_regs) — that's just how it's printed, girl, don't come for her 🎀

---

🌸 NAME 🌸

idpf_map_remaining_mmio_regs — maps the MMIO regions that live outside mbx and rstat. that's the whole vibe 💅

---

✨ SYNOPSIS ✨

int idpf_map_remaining_mmio_regs (struct idpf_adapter *adapter );

---

🫶 ARGUMENTS 🫶

• adapter — the driver-specific private structure. she's the main character of this whole function, fr fr 💖

---

🦋 DESCRIPTION 🦋

so here's the tea 🍵 this one gets called when idpf_cfg_lan_memory_regions is not supported. like, the fancy config path said no, so we're doing it the manual way, and honestly? iconic.

what she does: calculates the offsets and sizes for the regions before, in between, and after the mailbox and rstat MMIO mappings — then maps those ranges. no cap, she's literally doing geometry for your registers 📐✨

---

🔥 RETURN 🔥

• 0 on success — slay 💚
• or an error code on failure 😭 (it's giving "something went wrong, check on her")

💀 real talk though: this is kernel-level MMIO mapping, so if the offsets and sizes are wrong, things go very bad very fast. she's a precise queen — treat her like one.
