      "message": "clocksource: allow usage independent of timekeeping.c\n\nSo far struct clocksource acted as the interface between time/timekeeping.c\nand hardware. This patch generalizes the concept so that a similar\ninterface can also be used in other contexts. For that it introduces\nnew structures and related functions *without* touching the existing\nstruct clocksource.\n\nThe reasons for adding these new structures to clocksource.[ch] are\n* the APIs are clearly related\n* struct clocksource could be cleaned up to use the new structs\n* avoids proliferation of files with similar names (timesource.h?\n  timecounter.h?)\n\nAs outlined in the discussion with John Stultz, this patch adds\n* struct cyclecounter: stateless API to hardware which counts clock cycles\n* struct timecounter: stateful utility code built on a cyclecounter which\n  provides a nanosecond counter\n* only the function to read the nanosecond counter; deltas are used internally\n  and not exposed to users of timecounter\n\nThe code does no locking of the shared state. It must be called at least\nas often as the cycle counter wraps around to detect these wrap arounds.\nBoth is the responsibility of the timecounter user.\n\nAcked-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Patrick Ohly \u003cpatrick.ohly@intel.com\u003e\nSigned-off-by: David S.

      "message": "clocksource: introduce CLOCK_MONOTONIC_RAW\n\nIn talking with Josip Loncaric, and his work on clock synchronization (see\nbtime.sf.net), he mentioned that for really close synchronization, it is\nuseful to have access to \"hardware time\", that is a notion of time that is\nnot in any way adjusted by the clock slewing done to keep close time sync.\n\nPart of the issue is if we are using the kernel\u0027s ntp adjusted\nrepresentation of time in order to measure how we should correct time, we\ncan run into what Paul McKenney aptly described as \"Painting a road using\nthe lines we\u0027re painting as the guide\".\n\nI had been thinking of a similar problem, and was trying to come up with a\nway to give users access to a purely hardware based time representation\nthat avoided users having to know the underlying frequency and mask values\nneeded to deal with the wide variety of possible underlying hardware\ncounters.\n\nMy solution is to introduce CLOCK_MONOTONIC_RAW.  This exposes a\nnanosecond based time value, that increments starting at bootup and has no\nfrequency adjustments made to it what so ever.\n\nThe time is accessed from userspace via the posix_clock_gettime() syscall,\npassing CLOCK_MONOTONIC_RAW as the clock_id.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

Currently, when NTP makes\nadjustments to the clock frequency, they are made directly to the mult\nvalue.\n\nThis has the drawback that once changed, we cannot know what the orignal\nmult value was, or how much adjustment has been applied.\n\nThis property causes problems in calculating proper ntp intervals when\nswitching back and forth between clocksources.\n\nThis patch separates the current mult value into a mult and mult_orig\npair.  The mult_orig value stays constant, while the ntp clocksource\nadjustments are done only to the mult value.\n\nThis allows for correct ntp interval calculation and additionally lays the\ngroundwork for a new notion of time, what I\u0027m calling the monotonic-raw\ntime, which is introduced in a following patch.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
