[Xen-devel] Question about i386 ioremap()
There is a comment in include/asm-xen/asm-i386/io.h which states:
/**
* ioremap - map bus memory into CPU space
* @offset: bus address of the memory
* @size: size of the resource to map
*
* 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.
*/
Is this correct? Isn't this true only in the case of ioremap_nocache()?
Thanks
Aravindh
