.BI "void __iomem * ioremap_nocache(resource_size_t\ " "offset" ", unsigned\ long\ " "size" ");"
.SH "ARGUMENTS"

.SH "DESCRIPTION"
.PP
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\&.
.PP
If the area you are trying to map is a PCI BAR you should have a look at
\fBpci_iomap\fR\&.
