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": "53f087febfd12e74ba9f1082e71e9a45adc039ad", "tree": "8908ff3ecc3c97fb536c616df0f9d46356c4739f", "parents": [ "76edc6051e02186fe664ab880447e2d1f96fd884" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Feb 01 05:56:41 2006 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Feb 07 20:57:42 2006 -0500" }, "message": "[PATCH] timer.c NULL noise removal\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "6ba1b91213e81aa92b5cf7539f7d2a94ff54947c", "tree": "0d461bf7c7f444a80d09f09501e9fb378a78220f", "parents": [ "10c94ec16dd187f8d8dfdbb088e98330c05bf03c" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Mon Jan 09 20:52:36 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jan 10 08:01:38 2006 -0800" }, "message": "[PATCH] hrtimer: switch sys_nanosleep to hrtimer\n\nconvert sys_nanosleep() to use hrtimer_nanosleep()\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c0a3132963db68f1fbbd0e316b73de100fee3f08", "tree": "cdd76aacf0ca7ae7780696a06bf9643f8b245ba1", "parents": [ "97fc79f97b1111c80010d34ee66312b88f531e41" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Mon Jan 09 20:52:32 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jan 10 08:01:37 2006 -0800" }, "message": "[PATCH] hrtimer: hrtimer core code\n\nhrtimer subsystem core.

The timer can be fired again after\n del_timer_sync have checked all cpus and before it will recheck\n timer_pending().\n\n2. It has scalability problems. All cpus are scanned to determine\n if the timer is running on that cpu.\n\n With this patch del_timer_sync is O(1) and no slower than plain\n del_timer(pending_timer), unless it has to actually wait for\n completion of the currently running timer.\n\n The only restriction is that the recurring timer should not use\n add_timer_on().\n\n3. The timers are not serialized wrt to itself.\n\n If CPU_0 does mod_timer(jiffies+1) while the timer is currently\n running on CPU 1, it is quite possible that local interrupt on\n CPU_0 will start that timer before it finished on CPU_1.\n\n4. The timers locking is suboptimal. __mod_timer() takes 3 locks\n at once and still requires wmb() in del_timer/run_timers.\n\n The new implementation takes 2 locks sequentially and does not\n need memory barriers.\n\nCurrently -\u003ebase !\u003d NULL means that the timer is pending. In that case\n-\u003ebase.lock is used to lock the timer. __mod_timer also takes timer-\u003elock\nbecause -\u003ebase can be \u003d\u003d NULL.\n\nThis patch uses timer-\u003eentry.next !\u003d NULL as indication that the timer is\npending. So it does __list_del(), entry-\u003enext \u003d NULL instead of list_del()\nwhen the timer is deleted.\n\nThe -\u003ebase field is used for hashed locking only, it is initialized\nin init_timer() which sets -\u003ebase \u003d per_cpu(tvec_bases). When the\ntvec_bases.lock is locked, it means that all timers which are tied\nto this base via timer-\u003ebase are locked, and the base itself is locked\ntoo.\n\nSo __run_timers/migrate_timers can safely modify all timers which could\nbe found on -\u003etvX lists (pending timers).\n\nWhen the timer\u0027s base is locked, and the timer removed from -\u003eentry list\n(which means that _run_timers/migrate_timers can\u0027t see this timer), it is\npossible to set timer-\u003ebase \u003d NULL and drop the lock: the timer remains\nlocked.\n\nThis patch adds lock_timer_base() helper, which waits for -\u003ebase !\u003d NULL,\nlocks the -\u003ebase, and checks it is still the same.\n\n__mod_timer() schedules the timer on the local CPU and changes it\u0027s base.\nHowever, it does not lock both old and new bases at once. It locks the\ntimer via lock_timer_base(), deletes the timer, sets -\u003ebase \u003d NULL, and\nunlocks old base. Then __mod_timer() locks new_base, sets -\u003ebase \u003d new_base,\nand adds this timer. This simplifies the code, because AB-BA deadlock is not\npossible. __mod_timer() also ensures that the timer\u0027s base is not changed\nwhile the timer\u0027s handler is running on the old base.\n\n__run_timers(), del_timer() do not change -\u003ebase anymore, they only clear\npending flag.\n\nSo del_timer_sync() can test timer-\u003ebase-\u003erunning_timer \u003d\u003d timer to detect\nwhether it is running or not.\n\nWe don\u0027t need timer_list-\u003elock anymore, this patch kills it.\n\nWe also don\u0027t need barriers. del_timer() and __run_timers() used smp_wmb()\nbefore clearing timer\u0027s pending flag. It was needed because __mod_timer()\ndid not lock old_base if the timer is not pending, so __mod_timer()-\u003elist_add()\ncould race with del_timer()-\u003elist_del(). With this patch these functions are\nserialized through base-\u003elock.\n\nOne problem. TIMER_INITIALIZER can\u0027t use per_cpu(tvec_bases). So this patch\nadds global\n\n struct timer_base_s {\n spinlock_t lock;\n struct timer_list *running_timer;\n } __init_timer_base;\n\nwhich is used by TIMER_INITIALIZER. The corresponding fields in tvec_t_base_s\nstruct are replaced by struct timer_base_s t_base.\n\nIt is indeed ugly. But this can\u0027t have scalability problems. The global\n__init_timer_base.lock is used only when __mod_timer() is called for the first\ntime AND the timer was compile time initialized. After that the timer migrates\nto the local CPU.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Renaud Lienhart \u003crenaud.lienhart@free.fr\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d59dd4620fb8d6422555a9e2b82a707718e68327", "tree": "78205657d24efcaa3f8314064951ac3814ed95a7", "parents": [ "0d8d4d42f2d00eb65262b49f4edd4cf7ef4eb6fc" ], "author": { "name": "akpm@osdl.org", "email": "akpm@osdl.org", "time": "Sun May 01 08:58:47 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun May 01 08:58:47 2005 -0700" }, "message": "[PATCH] use smp_mb/wmb/rmb where possible\n\nReplace a number of memory barriers with smp_ variants.
