This kept the number of loops down, however it did\nslightly change how we make NTP adjustments. While not an issue\nwith NTPd users, as NTPd makes adjustments over a longer period of\ntime, other adjtimex() users have noticed the half-second\ngranularity with which we can apply frequency changes to the clock.\n\nFor instance, if a application tries to apply a 100ppm frequency\ncorrection for 20ms to correct a 2us offset, with NOHZ they either\nget no correction, or a 50us correction.\n\nNow, there will always be some granularity error for applying\nfrequency corrections. However with users sensitive to this error\nhave seen a 50-500x increase with NOHZ compared to running without\nNOHZ.\n\nSo I figured I\u0027d try another approach then just simply increasing\nthe interval. My approach is to consume the time interval\nlogarithmically. This reduces the number of times through the loop\nneeded keeping latency down, while still preserving the original\ngranularity error for adjtimex() changes.\n\nFurther, this change allows us to remove the xtime_cache code\n(patch to follow), as xtime is always within one tick of the\ncurrent time, instead of the half-second updates it saw before.\n\nAn earlier version of this patch has been shipping to x86 users in\nthe RedHat MRG releases for awhile without issue, but I\u0027ve reworked\nthis version to be even more careful about avoiding possible\noverflows if the shift value gets too large.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReviewed-by: John Kacur \u003cjkacur@redhat.com\u003e\nCc: Clark Williams \u003cwilliams@redhat.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nLKML-Reference: \u003c1254525473.7741.88.camel@localhost.localdomain\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c95b4502ad7fe8f3b9954aec794b00ac0046ab3a", "tree": "c0bf60bb669f0ed8cbd5e2037698454fdb144add", "parents": [ "326ba5010a5429a5a528b268b36a5900d4ab0eba" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Thu Aug 27 17:04:42 2009 -0700" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Aug 28 14:53:24 2009 +0200" }, "message": "ntp: Provide compability defines (You say MOD_NANO, I say ADJ_NANO)\n\nMOD_NANO, ADJ_NANO, MOD_NANO, ADJ_NANO!\nLets call the whole thing off!\nBut oh!

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" }, { "commit": "1bb34a412750291e4e5e9f1d0fe7ae1b7e976098", "tree": "00d481a2ff4302f444fbf7c31e5e661f79dc85a9", "parents": [ "9c0cbd54ce0397017a823484f9a8054ab369b8a2" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Sun Oct 30 15:01:42 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 30 17:37:18 2005 -0800" }, "message": "[PATCH] NTP shift_right cleanup\n\nCreate a macro shift_right() that avoids the numerous ugly conditionals in the\nNTP code that look like:\n\n if(a \u003c 0)\n b \u003d -(-a \u003e\u003e shift);\n else\n b \u003d a \u003e\u003e shift;\n\nReplacing it with:\n\n b \u003d shift_right(a, shift);\n\nThis should have zero effect on the logic, however it should probably have\na bit of testing just to be sure.\n\nAlso replace open-coded min/max with the macros.\n\nSigned-off-by : John Stultz \u003cjohnstul@us.ibm.com\u003e\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b149ee2233edf08fb59b11e879a2c5941929bcb8", "tree": "4ee8e066c4d69ac98afc37ab0ab62ae54271ce02", "parents": [ "6c231b7bab0aa6860cd9da2de8a064eddc34c146" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Tue Sep 06 15:17:46 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:34 2005 -0700" }, "message": "[PATCH] NTP: ntp-helper functions\n\nThis patch cleans up a commonly repeated set of changes to the NTP state\nvariables by adding two helper inline functions:\n\nntp_clear(): Clears the ntp state variables\n\nntp_synced(): Returns 1 if the system is synced with a time server.\n\nThis was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc,\nsparc64.\n\nSigned-off-by: 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" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
