| |
Hi,
I am trying to port bus_to_virt and virt_to_bus to the DMA-mapping scheme. I found a way to move virt_to_bus() as follows: page = virt_to_page(cmd->request_buffer); offset = (unsigned long)address & ~PAGE_MASK; dma_addr_t addr = pci_map_page(dev, page, offset, size,direction);
But now I want to get virtual address for dma_addr_t.
Any help is greatly appreciated.
with regards, Anil
