Seems dom0 ops are completely disabled for domUs, even for domid == DOMID_SELF. I need shared_info->arch.max_pfn ... Even if you could get address of shared_info, you can't map it into user space without some kernel hacking to make that possible (/dev/mem can only map I/O memory when running on Xen). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
