✨ iommu_dma_init_options ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's short and sweet — it's iommu_dma_init_options, and no cap it's literally just "set up the options struct." Let's get into it 🎀

🌸 SYNOPSIS 🌸

void iommu_dma_init_options (struct iommu_dma_options *options , struct
       device *dev );

like, that's the whole thing. it returns void — nothing comes back, she just does her thing and dips 🦋

🫶 ARGUMENTS 🫶

  • options — the options to be initialized 💖 this is the struct you're handing over, and she's gonna fill it in for you.
  • dev — the device the options are set for ✨ so like, whose vibe are we tuning here? this device. it's this one.

👑 DESCRIPTION 👑

This is the little tuning hook — it lets the dma-iommu stuff get customized to match the device's properties 🌈 that's it, that's the whole job. specific to device properties, periodt.
