pci_map_single函数在Linux内核中起着重要的作用。通过调用该函数,可以将PCI设备的内存空间映射到主机系统的内存空间中,从而实现对PCI设备的访问。pci_map_single函数的定义如下: ```c void *pci_map_single(struct pci_dev *pdev, dma_addr_t addr, size_t size, enum pci_dma_data_direction dir); ```...

There has been talk of deprecating dma_map_single() in favour of dma_map_sg() (i.e. make all transfers use scatter/gather and eliminate dma_map_single() in favour of a single sg entry table) but nothing has been done about it (at least as far as I know). James Thanks, Jamie W...
