✨ NAME ✨

iommufd_vfio_compat_ioas_get_id — bestie, this is the one that makes sure a compat IOAS actually exists 💅

(this is a section 9 kernel API page from the Kernel API Manual, iykyk 🎀)

🌸 SYNOPSIS 🌸

int iommufd_vfio_compat_ioas_get_id (struct iommufd_ctx *ictx , u32
*out_ioas_id );

okay so it hands you back an int, and yes we love a return value moment 🫶

🦋 ARGUMENTS 🦋

• ictx — the context you're operating on, like, the whole vibe you're working inside of ✨
• out_ioas_id — the IOAS ID of the compatibility IOAS. this is where the answer lands, no cap 🎯

---

💖 DESCRIPTION 💖

Return the ID of the current compatibility IOAS. literally that's the whole job and it ate 🔥

The ID can be passed into other functions that take an ioas_id — so think of it as the little golden ticket you hand off to your other functions so they know which IOAS you mean 👑
