rio_unmap_inb_region(9)

💖 NAME 💖

okay bestie, welcome to the rio_unmap_inb_region(9) page from the Kernel API Manual — this is the group-chat moment where we talk about how to Unmap the inbound memory region. that's the whole gig. no cap. 💅

✨ SYNOPSIS ✨

void rio_unmap_inb_region (struct rio_mport *mport , dma_addr_t lstart
);

like, that's the signature, bestie — keep it exactly like that 🫶

🎀 ARGUMENTS 🎀

• mport — the master port. yep, that's the argument label, and honestly it's giving main-character port energy.
• lstart — the physical address of memory region to be unmapped. literally the address of the memory region getting unmapped, no extra lore. ✨
