virtqueue_map_free_coherent(9)

💅 virtqueue_map_free_coherent(9) 💅

okay bestie, welcome to the Kernel API Manual page for virtqueue_map_free_coherent(9) — and yes, we’re gonna make it make sense. ✨ It’s giving “tiny cleanup function with main character energy,” and we’re obsessed. 🫶

💖 NAME 💖

virtqueue_map_free_coherent — free coherent mapping. literally the whole name, no cap. 💅

✨ SYNOPSIS ✨

the signature, untouched, because we do not play games with code:

void virtqueue_map_free_coherent (struct virtio_device *vdev , union
virtio_map map , size_t size , void *vaddr , dma_addr_t map_handle );

🎀 ARGUMENTS 🎀

• vdev — the virtio device we are talking to, bestie. that’s the main character right there. 👑
• map — metadata for performing mapping. it’s the little helper-info situation for the mapping, iykyk. ✨
• size — the size of the buffer. yes, the actual size, no cap. 📏
• vaddr — the virtual address that needs to be freed. bye bestie, you’re getting the free treatment. 💅
• map_handle — the mapped address that needs to be freed. also getting the free treatment, slay. 🫶
