Hi, I am writing a device driver for PCI-X card in linux. Card memory is mapped to BAR-2 register. I got the physical address from BAR-2 using pci_resource_start() function. Then i try to get virtual address using ioremap_nocache(). But it returns virtual address as 0xffffffff. Regards, Munees. Kernelnewbies: Help each other learn about the Linux kernel.
