Peter Anvin" <hpa@...or.com>, x86@...nel.org, Andy Lutomirski <luto@...capital.net> Subject: [PATCH v1 0/3] x86/xen: pvclock vdso support Hey, This small series presents support for vDSO for Xen domains. 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 and Patch 3 (new in this version) adds an entry to maintainers for tracking pvclock ABI changes. Changelog since RFC is included in individual patches. Any comments/suggestions are welcome. 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 | 22 ++++++++++-------- arch/x86/kernel/kvmclock.c | 6 +---- arch/x86/kernel/pvclock.c | 13 +++++++++++ arch/x86/xen/enlighten.c | 2 ++ arch/x86/xen/time.c | 51 ++++++++++++++++++++++++++++++++++++++++++ arch/x86/xen/xen-ops.h | 1 + include/xen/interface/vcpu.h | 28 +++++++++++++++++++++++ 8 files changed, 111 insertions(+), 14 deletions(-) -- 2.1.4
