From: "Yong, Jonathan" <jonathan.y...@intel.com> This series introduces convert_art_to_tsc, to convert ART time to TSC. The main advantage of ART is that ART can be captured simultaneous to the capture of audio and network device clocks, allowing a correlation between timebases to be constructed.
The getnstime_raw_and_real symbol has been renamed to ktime_get_raw_and_real_ts64, including in all consumers. All patches are already in Linus's kernel. Patches should apply for linux-yocto-4.1 standard/base. Arnd Bergmann (1): ntp/pps: replace getnstime_raw_and_real with 64-bit version Christopher S. Hall (4): time: Add cycles to nanoseconds translation time: Add timekeeping snapshot code capturing system time and counter time: Add driver cross timestamp interface for higher precision time synchronization x86/tsc: Always Running Timer (ART) correlated clocksource DengChao (1): timekeeping: Provide internal function __ktime_get_real_seconds arch/x86/include/asm/cpufeature.h | 2 +- arch/x86/include/asm/tsc.h | 2 + arch/x86/kernel/tsc.c | 59 ++++++++++++++++ include/linux/pps_kernel.h | 7 +- include/linux/timekeeping.h | 57 +++++++++++++++- kernel/time/timekeeping.c | 136 ++++++++++++++++++++++++++++++++++--- kernel/time/timekeeping_internal.h | 2 + 7 files changed, 251 insertions(+), 14 deletions(-) -- 2.7.3 -- _______________________________________________ linux-yocto mailing list linux-yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/linux-yocto
