PVCLOCK_TSC_STABLE_BIT can be set starting Xen 4.8 which is required for vdso time related calls. In order to have it on, you need to have the hypervisor clocksource be TSC e.g. with the following boot params "clocksource=tsc tsc=stable:socket". Series is structured as following: Patch 1 probes for kvm guest in ptp_kvm in the event having pvclock_pvti_cpu0_va() moved to common pvclock (on the next patch) Patch 2 streamlines pvti page get/set in pvclock for both of its users Patch 3,4 registers the pvti page on Xen and sets it in pvclock accordingly Patch 5 adds a file to KVM/Xen maintainers for tracking pvclock ABI changes. [ Only patches 1 and 2 requires ack/review - the rest is acked/reviewed ] Changelog is in individual patches.
