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 streamlines pvti page get/set in pvclock for both of its users Patch 2 registers the pvti page on Xen and sets it in pvclock accordingly Patch 3 adds a file to KVM/Xen maintainers for tracking pvclock ABI changes. Changelog is included in individual patches. (only patch 2 changed in this version) Thanks, Joao Joao Martins (3): x86/pvclock: add setter for pvclock_pvti_cpu0_va x86/xen/time: setup vcpu 0 time info page MAINTAINERS: xen, kvm: track pvclock-abi.h changes MAINTAINERS | 2 + arch/x86/include/asm/pvclock.h | 19 ++++---- arch/x86/kernel/kvmclock.c | 7 +-- arch/x86/kernel/pvclock.c | 14 ++++++ arch/x86/xen/suspend.c | 4 ++ arch/x86/xen/time.c | 100 +++++++++++++++++++++++++++++++++++++++++ arch/x86/xen/xen-ops.h | 2 + include/xen/interface/vcpu.h | 42 +++++++++++++++++ 8 files changed, 175 insertions(+), 15 deletions(-) -- 2.11.0
