Hi all, this series introduces PV wallclock time support on arm and arm64. Changes in v5: - set interface_version to XENPF_INTERFACE_VERSION in an hypercall wrapper - remove trailing whitespace - remove unhelpful printk Changes in v4: - simplify xen_read_wallclock - add a patch to support XENPF_settime64 on x86 Changes in v3: - use ktime_get_ns instead of calling into the arch_timer functions directly - read the wallclock from the late_initcall - s/%llu.%0u/%llu.%09u - in xen_pvclock_gtod_notify use the passed struct timekeeper pointer rather than calling __current_kernel_time64 - use the passed struct timekeeper pointer to get the system time too - drop introduce __current_kernel_time64 Changes in v2: - introduce __current_kernel_time64 - rename dom0_op to platform_op - introduce XENPF_settime64 - extend pvclock_wall_clock with sec_hi - properly convert arch_timer ticker to nsec - use timespec64 interfaces - use sec_hi to get a 64-bit seconds value - use XENPF_settime64 - rename dom0_op to platform_op Stefano Stabellini (7): xen: rename dom0_op to platform_op xen/arm: introduce HYPERVISOR_platform_op on arm and arm64 xen: introduce XENPF_settime64 arm: extend pvclock_wall_clock with sec_hi xen/arm: introduce xen_read_wallclock xen/arm: set the system time in Xen via the XENPF_settime64 hypercall xen/x86: support XENPF_settime64 arch/arm/include/asm/xen/hypercall.h | 7 ++++ arch/arm/include/asm/xen/interface.h | 3 ++ arch/arm/xen/enlighten.c | 76 ++++++++++++++++++++++++++++++++++ arch/arm/xen/hypercall.S | 1 + arch/arm64/xen/hypercall.S | 1 + arch/x86/include/asm/xen/hypercall.h | 6 +-- arch/x86/xen/apic.c | 2 +- arch/x86/xen/enlighten.c | 8 ++-- arch/x86/xen/time.c | 35 ++++++++++++---- drivers/xen/acpi.c | 2 +- drivers/xen/efi.c | 30 +++++++------- drivers/xen/pcpu.c | 8 ++-- drivers/xen/xen-acpi-cpuhotplug.c | 2 +- drivers/xen/xen-acpi-pad.c | 4 +- drivers/xen/xen-acpi-processor.c | 8 ++-- drivers/xen/xenfs/xensyms.c | 4 +- include/xen/interface/platform.h | 18 ++++++-- include/xen/interface/xen.h | 2 +- 18 files changed, 168 insertions(+), 49 deletions(-) Cheers, Stefano _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
