iommu_free_pages(9)

💖 NAME 💖

iommu_free_pages — bestie, it frees pages. that's the whole vibe ✨

🌸 SYNOPSIS 🌸

void iommu_free_pages (void *virt );

🎀 ARGUMENTS 🎀

• virt — the virtual address of the page you're freeing. like, the actual address of the page. hand it over and it's gone 🫶

🦋 DESCRIPTION 🦋

okay so here's the thing, and this is important: the page you're passing in must have been allocated by iommu_alloc_pages_node_sz. that's not a suggestion, that's the rule 💅 if it came from anywhere else, you're not in the allocated-by-the-right-function club and we can't help you 😭

lowkey do a vibe check on your pointer before you call this. was it born from iommu_alloc_pages_node_sz? yes? slay, proceed. no? absolutely do not 🙈
