vringh_init_iotlb(9)

okay bestie, this one's from the Kernel API Manual and it's giving "tiny function, big main character energy" — we're folding that manual name in right here at the top so nobody's confused 💅✨

🎀 NAME 🎀

vringh_init_iotlb — initialize a vringh for a ring with IOTLB. that's the whole vibe, short and iconic 🦋

💖 SYNOPSIS 💖

int vringh_init_iotlb (struct vringh *vrh , u64 features , unsigned int
num , bool weak_barriers , struct vring_desc *desc , struct vring_avail
*avail , struct vring_used *used );

🍓 ARGUMENTS 🍓

• vrh — the vringh you're initializing. it's the one getting glowed up, lowkey the main character here 👑
• features — the feature bits for this ring. like its personality settings ✨
• num — the number of elements. and yes, it has to be valid, we'll get to that 😭
• weak_barriers — true if we only need memory barriers, not I/O. so like, barriers-lite 🧚
• desc — the userspace descriptor pointer. point it at the descriptor situation 🎀
• avail — the userspace avail pointer. hand over the avail pointer, bestie 🫶
• used — the userspace used pointer. and the used pointer too, don't forget 💜

🔥 DESCRIPTION 🔥

Returns an error if num is invalid. that's literally the whole description, no cap — if num is invalid, it returns an error, periodt 💀
