This can cause\ntime jumps in the range of hours.\n\nThis was reported in:\n http://lkml.org/lkml/2007/8/23/96\nand\n http://lkml.org/lkml/2008/3/31/23\n\nI was able to reproduce the problem with a gettimeofday loop test on a\ndual core and a quad core machine which both have sychronized\nTSCs. The TSCs seems not to be perfectly in sync though, but the\nkernel is not able to detect the slight delta in the sync check. Still\nthere exists an extremly small window where this delta can be observed\nwith a real big time jump. So far I was only able to reproduce this\nwith the vsyscall gettimeofday implementation, but in theory this\nmight be observable with the syscall based version as well.\n\nCPU 0 updates the clock source variables under xtime/vyscall lock and\nCPU1, where the TSC is slighty behind CPU0, is reading the time right\nafter the seqlock was unlocked.\n\nThe clocksource reference data was updated with the TSC from CPU0 and\nthe value which is read from TSC on CPU1 is less than the reference\ndata. This results in a huge delta value due to the unsigned\nsubtraction of the TSC value and the reference value. This algorithm\ncan not be changed due to the support of wrapping clock sources like\npm timer.\n\nThe huge delta is converted to nanoseconds and added to xtime, which\nis then observable by the caller. The next gettimeofday call on CPU1\nwill show the correct time again as now the TSC has advanced above the\nreference value.\n\nTo prevent this TSC specific wreckage we need to compare the TSC value\nagainst the reference value and return the latter when it is larger\nthan the actual TSC value.\n\nI pondered to mark the TSC unstable when the readout is smaller than\nthe reference value, but this would render an otherwise good and fast\nclocksource unusable without a real good reason.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "8fb402bccf203ecca8f9e0202b8fd3c937dece6f", "tree": "4f102f9cc81dedbf9271f728a4b1e6e731a6a174", "parents": [ "5deb45e39b946901ae028ccd3a1d0b35fa387475" ], "author": { "name": "Erik Bosman", "email": "ebn310@few.vu.nl", "time": "Fri Apr 11 18:54:17 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sat Apr 19 19:19:55 2008 +0200" }, "message": "generic, x86: add prctl commands PR_GET_TSC and PR_SET_TSC\n\nThis patch adds prctl commands that make it possible\nto deny the execution of timestamp counters in userspace.\nIf this is not implemented on a specific architecture,\nprctl will return -EINVAL.\n\nned-off-by: Erik Bosman \u003cejbosman@cs.vu.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "a6550207538619bc9b90bac2e1d5e54902a432ad", "tree": "cc9bb9b5153810b544c2afcc7721353ff5ce957d", "parents": [ "5a6483feb0c5193519625d0ea8c4254364d423cc" ], "author": { "name": "Matthew Wilcox", "email": "matthew@wil.cx", "time": "Tue Feb 26 10:47:18 2008 -0500" }, "committer": { "name": "Matthew Wilcox", "email": "willy@linux.intel.com", "time": "Fri Apr 18 22:17:04 2008 -0400" }, "message": "kernel: Remove unnecessary inclusions of asm/semaphore.h\n\nNone of these files use any of the functionality promised by\nasm/semaphore.h.\n\nSigned-off-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\n" }, { "commit": "04305e4aff8b0533dc05f9f6f1a34d0796bd985f", "tree": "9938264917b4b9e6e147b883d88fca94c6788b76", "parents": [ "9d57a7f9e23dc30783d245280fc9907cf2c87837" ], "author": { "name": "Ahmed S.
