However I don't see it being used anywhere.Could someone point me to the place where it is being used.Reason I ask is because I need to map certain physical memory in "xen", some device register's available in memory space. As I see, there is no directioremap support in xen (atleast the comment says so!). fixmap uses that area, but I think that's now the only thing that uses that area in Xen. We removed dynamic ioremap when we removed device drivers from Xen. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
