...are defined to be the logical OR of the values for the mapping and the physical page. This patch implements the necessary changes in pgtable.h for s390. There is a common code change in mm/rmap.c, the call to page_test_and_clear_young must be moved. This is a no-op for all architecture but s390. page_referenced checks the referenced bits for the physiscal page and for all mappings: o The physical page is checked with page_test_and_clear_young. o The mappings are checked with ptep_test_and_clear_young and friends. Without pgstes (the current implementation on Linux s390) the physical page check is imple...

Hi, AFAIK, the status of Xen in lenny is currently the following: - no dom0 kernel - domU kernel only for i386 (no domU kernel for amd64) I was told (I don't remember where) that this is because the vanilla kernel only supports domU for i386, and has no dom0 support, so distros have to port the patches to their kernels (please correct me if I'm wrong). However: - etch shipped with dom0

This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git

Hi everyone, I am very excited to see that dom0 pvops is finally coming close to working, so I wanted to give it a try. >From the description it was not clear to me which kernel to chose as base for the patches.hg, so I took the latest (that was ~ 2 weeks ago) kernel on git.kernel.org I could find (post-2.6.28 git tip at that point). I managed to more or less apply all of the patches in the

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
