[PATCH] cleanup: time.h, times.h, timex.h and jiffies.h

2004-10-19T01:13:49Z

This patch moves some definitions among time.h, times.h, timex.h and jiffies.h. The purpose is to sort all jiffies related functions to jiffies.h, to get rid of the cyclic dependency between time.h & timex.h and to move all #include lines to the start of the header files.

[PATCH] Fix reporting of process start times

2004-10-13T14:27:49Z

Derive process start times from the posix_clock_monotonic notion of uptime instead of "jiffies", consistent with the earlier change to /proc/uptime itself. (http://linus.bkbits.net:8080/linux-2.5/cset@3ef4851dGg0fxX58R9Zv8SIq9fzNmQ?na%0Av=index.html|src/.|src/fs|src/fs/proc|related/fs/proc/proc_misc.c) Process start times are reported to userspace in units of 1/USER_HZ since boot, thus applications as procps need the value of "uptime" to convert them into absolute time. Currently "uptime" is derived from an ntp-corrected time base, but process start time is derived from the free-running "jiffies" counter. This results in inaccurate, drifting process start times as seen by the user, even if the exported number stays constant, because the users notion of "jiffies" changes in time. It's John Stultz's patch anyways, which I only messed up a bit, but since people started trading signed-off lines on lkml: Signed-off-by: Tim Schmielau Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] jiffies-to-clockt fix

2004-05-10T07:05:07Z

From: john stultz This patch polishes up Tim Schmielau's (tim@physik3.uni-rostock.de) fix for jiffies_to_clock_t() and jiffies_64_to_clock_t(). The issues observed was w/ /proc output not matching up to wall time due to accumulated error caused by HZ not being exactly 1000 on i386 systems. The solution is to correct that error by using the more accurate TICK_NSEC in our calculation. Additionally, this patch corrects 3 warnings in the TCP layer uncovered by this change.

[JIFFIES]: linux/times.h needs asm/param.h (for USER_HZ)

Add "clock_t_to_jiffies()" conversion function with

some rather minimal overflow protection.

[PATCH] use 64 bit jiffies: infrastructure

2003-02-04T02:19:44Z

Provide a sane way to avoid unneccessary locking on 64 bit platforms, and a 64 bit analogous to "jiffies_to_clock_t()".

Make in-kernel HZ be 1000 on x86, retaining user-level 100 HZ clock_t.

2002-07-01T07:41:38Z

Stop using "struct tms" internally - always use timer ticks (or one of the sane timeval/timespec types) instead. Explicitly convert to clock_t when copying to user space for the old broken interfaces that still use "clock_t". Clean up and unify jiffies<->timeval conversion.
