As computers have gotten faster and can now\nsplit microseconds easily, a new kernel interface using nanosecond units was\ndefined (\"the nanokernel\", confusing as that name is to OS hackers), and\nthere\u0027s an STA_NANO bit in the adjtimex() status field to tell the application\nwhich units it\u0027s using.\n\nThe current ntpd supports both, but Linux loses some possible timing\nresolution because of quantization effects, and the ntpd hackers would really\nlike to be able to drop the backwards compatibility code.\n\nUlrich Windl has been maintaining a patch set to do the conversion for years,\nbut it\u0027s hard to keep in sync.\n\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] Provide an interface for getting the current tick length\n\nThis provides an interface for arch code to find out how many\nnanoseconds are going to be added on to xtime by the next call to\ndo_timer.  The value returned is a fixed-point number in 52.12 format\nin nanoseconds.  The reason for this format is that it gives the\nfull precision that the timekeeping code is using internally.\n\nThe motivation for this is to fix a problem that has arisen on 32-bit\npowerpc in that the value returned by do_gettimeofday drifts apart\nfrom xtime if NTP is being used.  PowerPC is now using a lockless\ndo_gettimeofday based on reading the timebase register and performing\nsome simple arithmetic.  (This method of getting the time is also\nexported to userspace via the VDSO.)  However, the factor and offset\nit uses were calculated based on the nominal tick length and weren\u0027t\nbeing adjusted when NTP varied the tick length.\n\nNote that 64-bit powerpc has had the lockless do_gettimeofday for a\nlong time now.  It also had an extremely hairy routine that got called\nfrom the 32-bit compat routine for adjtimex, which adjusted the\nfactor and offset according to what it thought the timekeeping code\nwas going to do.  Not only was this only called if a 32-bit task did\nadjtimex (i.e. not if a 64-bit task did adjtimex), it was also\nduplicating computations from kernel/timer.c and it wasn\u0027t clear that\nit was (still) correct.\n\nThe simple solution is to ask the timekeeping code how long the\ncurrent jiffy will be on each timer interrupt, after calling\ndo_timer.  If this jiffy will be a different length from the last one,\nwe then need to compute new values for the factor and offset used in\nthe lockless do_gettimeofday.  In this way we can keep xtime and\ndo_gettimeofday in sync, even when NTP is varying the tick length.\n\nNote that when adjtimex varies the tick length, it almost always\nintroduces the variation from the next tick on.  The only case I could\nsee where adjtimex would vary the length of the current tick is when\nan old-style adjtime adjustment is being cancelled.  (It\u0027s not clear\nto me why the adjustment has to be cancelled immediately rather than\nfrom the next tick on.)  Thus I don\u0027t see any real need for a hook in\nadjtimex; the rare case of an old-style adjustment being cancelled can\nbe fixed up at the next tick.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
