💅 free_io_pgtable_ops(9) — Kernel API Manual energy

okay bestie, this is the Kernel API Manual page for freeing an io_pgtable_ops structure. short page, big "read the fine print" energy. 💖

✨ NAME ✨

free_io_pgtable_ops — it frees an io_pgtable_ops structure. The caller must ensure that the page table is no longer live, but the TLB can be dirty. like, page table not live = required, dirty TLB = allowed. that's the vibe check. 🫶

🌸 SYNOPSIS 🌸

the signature is literally:

void free_io_pgtable_ops (struct io_pgtable_ops *ops );

🎀 ARGUMENTS 🎀

• ops — the ops returned from alloc_io_pgtable_ops. that's the pointer this function is here to free, bestie. ✨

🔥 SEE ALSO 🔥

• Kernel file: ./include/linux/io-pgtable.h
• struct iommu_flush_ops(9)
• struct io_pgtable_cfg(9)
• struct arm_lpae_io_pgtable_walk_data(9)

• alloc_io_pgtable_ops(9)
• struct io_pgtable(9)
• enum io_pgtable_caps(9)
• struct io_pgtable_init_fns(9)

lowkey the TLB being dirty is fine, but the page table being live is not it. the caller must make sure it's no longer live. no cap. 🚨
