Stolen ticks are clocksource ticks that have been "stolen" from the cpu, typically because Linux is running in a virtual machine and the vcpu has been descheduled. To account for these ticks we introduce CONFIG_PARAVIRT and pv_time_ops so that we can make use of: kernel/sched/cputime.c:steal_account_process_tick Stefano Stabellini (4): xen: move xen_setup_runstate_info and get_runstate_snapshot to drivers/xen/time.c arm: introduce CONFIG_PARAVIRT and pv_time_ops kernel: missing include in cputime.c xen/arm: account for stolen ticks arch/arm/Kconfig | 9 ++++ arch/arm/include/asm/paravirt.h | 19 ++++++++ arch/arm/kernel/Makefile | 1 + arch/arm/kernel/paravirt.c | 32 ++++++++++++++ arch/arm/xen/enlighten.c | 23 ++++++++++ arch/ia64/xen/time.c | 48 +++------------------ arch/x86/xen/time.c | 76 +-------------------------------- drivers/xen/Makefile | 2 +- drivers/xen/time.c | 91 +++++++++++++++++++++++++++++++++++++++ include/xen/xen-ops.h | 5 ++ kernel/sched/cputime.c | 1 + 11 files changed, 189 insertions(+), 118 deletions(-) create mode 100644 arch/arm/include/asm/paravirt.h create mode 100644 arch/arm/kernel/paravirt.c create mode 100644 drivers/xen/time.c Cheers, Stefano -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
