Hi some architectures (eg ia64) don''t have a canonical page size. It is possible to build kernels (and Xen) with different page size. Such configurations are not yet working, but as a first step this patch makes the info available. Ideally pagesize should be a field of platform_parameter but doing so would break binary compatibility. Tested on xen/ia64.

Presumably the guest at this point is happily running on the page size of its choice? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

But as soon as page operations are involved (domain construction, xenstore, grant operations) xen page size has to be known. Xen and domains have to agree on what is a page.
