IOREMAP_NOCACHE(9) Public Functions Provided IOREMAP_NOCACHE(9) NAME ioremap_nocache - map bus memory into CPU space SYNOPSIS void __iomem * ioremap_nocache(resource_size_t offset, unsigned long size); ARGUMENTS offset bus address of the memory size size of the resource to map DESCRIPTION ioremap performs a platform specific sequence of operations to make bus memory CPU accessible via the readb/readw/readl/writeb/ writew/writel functions and the other mmio helpers. The returned address is not guaranteed to be usable directly as a virtual address. If the area you are trying to map is a PCI BAR you should have a look at pci_iomap.
