When the hypervisor tries to do this grant in xen/common/grant_table.c it (i) notices that it is an iomem_map rather than device_map or host_map; (ii) it is from dom0; and (iii) it is not a RAM page. It then attempts to call iomem_permit_access(). Hi Karen, Thanks for the patch, I find it useful... but I am wondering why you need to check it is from a dom0 ... I maybe not getting the reason, but iomem_map should be available for page sharing among all domains, shouldn't it ? Thank you, -- Lamia Youseff _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
