Hi, I am new to linux device driver development and I'm trying to learn the DMA transfer. Currently I have created a DMA buffer using pci_alloc_consistent() function. Since I don't have a real DMA enabled pci device, so I am thinking of transfer the data in the DMA buffer to some other buffer within kernel space(let say created through kmalloc) using DMA.
Is it possible to do DMA transfer within kernel space? If yes, please provide some sample code for the same. Thanks in advance Ravi Gupta
