iosys_map_set_vaddr(9)

✨ iosys_map_set_vaddr ✨

okay so bestie, welcome to the Kernel API Manual 💅 you're about to meet iosys_map_set_vaddr, and honestly she's a whole vibe: she points a iosys_map structure at an address that lives in system memory. short, sweet, iconic 🎀

---

🌸 SYNOPSIS 🌸

void iosys_map_set_vaddr (struct iosys_map *map , void *vaddr );

like, that's the whole signature. no cap, that's it 🫶

---

💖 ARGUMENTS 💖

• map — the iosys_map structure in question 🗺️ she's the one getting updated.
• vaddr — a system-memory address. yep, the actual address goes here ✨

---

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓: this function sets the address and clears the I/O-memory flag. that's the whole job. she does both, she does them together, and she does them well. main character energy fr fr 👑

lowkey the important bit: the I/O-memory flag gets cleared, not set. so if you were hoping for an I/O-memory mapping, this is not the function for you — go say hi to iosys_map_set_vaddr_iomem instead 💀
