💖 NAME 💖

okay so bestie, this page is iommu_detach_group_handle(9) from the Kernel API Manual, and it is literally here to detach an IOMMU domain from an IOMMU group. no cap, that's the whole assignment. 🎀

void iommu_detach_group_handle (struct iommu_domain *domain , struct iommu_group *group );

🫶 ARGUMENTS 🫶

• domain — IOMMU domain to attach. 🌀
• group — IOMMU group that will be attached. 🧚
