Hi I am trying to use the uio_dmem_genirq.c driver for allocating DMA memory to a PCI device using the uio_pci_generic.c driver.
I got as far as defining an UIO dev containing only Dynamic DMA memory and now I am stuck. I can see how DMA memory is allocated when opening the /dev/uio device but I cannot figure out how to mmap this memory to User space as well so I can share this memory with the PCI device and my user space driver. What am I missing? Jocke
