Hi
I am working on a PCI device driver in Linux. I am trying to map 128MB PCI memory space to virtual address of Pentium CPU. I am observing that ioremap() call returns only PAGE ALIGNED virtual address. My device driver requires the virtual address to be 128MB aligned! (I need the virtual address start in the form - xxxx x000 0000
0000 0000 0000 0000 0000 (given in binary x-dont care).
How do I ensure it in Linux? Can anybody help me? Thanks, Murthy
