This series does some cleanup and precursor changes to the hyper-v clock source and introduces support for TSC page based clock in root partition. Hyper-V root partition requires kernel to map the page, specified by the hypervisor (instead of provide the PFN to the hypervisor like it's done in guest partition). v2: 1. Addressed all the comments to the commit messages. 2. TSC page in root partition is now remapped based on size of the tsc_pg variable. The following series implements... --- Stanislav Kinsburskiy (4): drivers/clocksource/hyper-v: Introduce a pointer to TSC page drivers/clocksource/hyper-v: Introduce TSC PFN getter drivers/clocksource/hyper-v: Use TSC PFN getter to map vvar page drivers/clocksource/hyper-v: Add TSC page support for root partition arch/x86/entry/vdso/vma.c | 7 ++--- arch/x86/hyperv/hv_init.c | 2 + drivers/clocksource/hyperv_timer.c | 54 +++++++++++++++++++++++++++--------- include/clocksource/hyperv_timer.h | 7 +++++ 4 files changed, 52 insertions(+), 18 deletions(-)
