Frederic, Here is a first pass at some changes needed in order to add ARM support.
I have another series coming that instruments the syscalls, exceptions etc. on ARM also, but this one is just to get some prerequisites out for broader discussion. This series applies on top of your 3.8-rc6-nohz4 branch, and is also available here: git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux.git wip/arm-nohz/prereq I'm aware of the >80 column warnings from checkpatch on the atomic64 conversion patch, but wanted to get some feedback on this approach before fixing all those up. Maybe some simpler wrappers in kernel_stat.h would make this a bit cleaner? Kevin Kevin Hilman (5): context tracking: conditionalize guest support based on CONFIG_KVM kernel_cpustat: convert to atomic 64-bit accessors virt CPU accounting: Kconfig: drop 64-bit requirment cputime: use do_div() for nsec resolution conversion helpers ARM: Kconfig: allow virt CPU accounting arch/arm/Kconfig | 1 + fs/proc/stat.c | 36 +++++++++++++------------- fs/proc/uptime.c | 2 +- include/asm-generic/cputime_nsecs.h | 51 +++++++++++++++++++++++++++---------- include/linux/kernel_stat.h | 2 +- init/Kconfig | 2 +- kernel/context_tracking.c | 4 +++ kernel/sched/core.c | 10 ++++---- kernel/sched/cputime.c | 24 ++++++++--------- 9 files changed, 80 insertions(+), 52 deletions(-) -- 1.8.1.2 _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
