Current status ,I have the required huge pages' mfn (reserved before dom 0 boots )which we pass on from hypervisor to domain to enable it to use this mfn to make required PTE . The problem lies that domain is unable to modify the PMD (as mentioned in above conversation) which contains this PTE entry as it lies in guest read-only memory as shown in xen's config.h file. So,we tried passing this PMD entry in a hypercall to the hypervisor to modify PMD accordingly but while allocation xen crashes. This is where we are stuck now. http://xen.1045712.n5.nabble.com/file/n3379235/jeremy2-6-32-27.patch jeremy2-6-32-27.patch http://xen.1045712.n5.nabble.com/file/n3379235/xen-patch.patch xen-patch.patch -- View this message in context: http://xen.1045712.n5.nabble.com/Linux-PATCH-Make-hugepages-work-in-current-git-tree-tp2540492p3379235.html Sent from the Xen - Dev mailing list archive at Nabble.com.
