hi, with writable page tables it takes a little more work tracking page types from within a domU. Basically, I need to duplicate Xen's pgd walks when pinning and unpinning pgds, within the domU, in order to obtain a consistent map of page types for my own pages. It seems it would be a lot easier just to allow domUs access to a DOM0_GETPAGEFRAMEINFO-like hypercall that would extract this info from Xen. Would you consider merging a patch to do this, and how/where would you prefer it to be implemented? thanks, Jacob _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
