🌸 NAME 🌸

vhost_iotlb_init β€” literally just initializes a vhost IOTLB. that's the whole vibe. it sets it up, it gets it ready, it slays. πŸ’…


πŸŽ€ SYNOPSIS πŸŽ€

void vhost_iotlb_init (struct vhost_iotlb *iotlb , unsigned int limit ,
       unsigned int flags );

no cap, that's the whole signature β€” three args, returns nothing (void), just vibes and initialization πŸ¦‹


✨ ARGUMENTS ✨

  • iotlb β€” the IOTLB that needs to be initialized πŸ‘‘ this is the main character of the function, the one getting its glow-up. it's a struct vhost_iotlb *, so hand over the pointer and let the function do its thing.
  • limit β€” maximum number of IOTLB entries πŸ”₯ like, the capacity. the ceiling. how many entries this IOTLB is allowed to hold before it's full, an unsigned int.
  • flags β€” VHOST_IOTLB_FLAG_XXX 🚩 that's the literal spelling in the manpage bestie, the XXX placeholder flags. it's an unsigned int, and it's the flag bag for this init.
