[Xen-devel] [PATCH 0/4] tools interface changes for supporting MFNs with 32 or more significant bits
In order to support now possible MFNs with 32 (or more) significant bits, two changes are required to the interfaces the Dom0 tools use: The individual page error indication must no longer be or-ed into the passed in MFN (because the bits used by the error indicator may collide with non-zero bits in the MFN), and a replacement for XEN_DOMCTL_getpageframeinfo2 is needed where full-width MFNs can be passed in and the result is being returned in a non-ambiguous way. 1) linux: add new (replacement) mmap-batch ioctl 2) libxc: use new (replacement) mmap-batch ioctl 3) qemu: use new (replacement) mmap-batch ioctl 4) add and use XEN_DOMCTL_getpageframeinfo3 Signed-off-by: Jan Beulich <jbeulich@novell.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
